- Quite possibly the dumbest project I've ever undertaken, this was an odyssey but well worth it in the end. It's hard to fully explain the depth of the rabbit hole that I was led down and I ended up having to study things like fluid dynamics, physics and chemistry. As the title suggests, this is a physically realistic (or at least, somewhat realistic) internal combustion engine simulation. It also generates audio which I feel is some of the best procedurally generated audio for a V8 engine I've ever heard.

I find it amusing that everyone on Reddit commenting on this has like 300 IQ and knows everything about engines AND simulations, but can't figure out that a simulation that runs in real-time and is intended for video game usage is not meant to replace professional engineering software. That's right guy from Reddit watching this, I'm talking to you. I did this for FUN to be used in GAMES and it's an *A P P R O X I M A T I O N* to generate cool audio. If it's so trivial and pointless, write a better one yourself and post a video about it. I'm looking forward to it.
Everyone else, thanks for watching! (sorry for the rant)
Me and my homies all hate that guy
hey I just beat him up for u got u bro
Yeah that reddit guy is an idiot. This project is epic! And i hope we get to see it being used in a video game!
what are your pc's specs and also is there a way to download this program
The most stupid people talk the loudest
this guy is the most chad programer i have ever seen, him so cassualy saying "I optimized this extremely accurate physics simulation to run at 85 thousand frames per second" and "I coded it in my own programming language for efficency" is absolutely insane
If Ange and jdh ever team up they could probably write a universe simulator
And built an engine in real life...
Scripting language* still super impresive
I thought "chad" is an insult?
@@Exitof99 ??? chad is a compliment
"Quite possibly the dumbest project I've ever undertaken" - Quite possibly the biggest understatement I've ever seen
I'm afraid to watch his other projects then :)
It really is something to behold I've seen alot of engine simulations but not like this... This is something else...
The best project he made. Doing video games and game engines - that is the dumbiest thing (I made some of this too). Now I am doing CAD editors and very happy with this )
i get the feeling that this project will pay off quite well for this individual in the long run
As a fourth dimensional being, I was surprised when a bunch of pistons and conrods suddenly appeared out of nowhere.
No harm, no foul.
Funniest thing I’ve ever heard
in 3 dimensions they disappear into nowhere. in 4 dimensions, you’d see them coming.
I get the joke but you got it the wrong way round, a 3 dimensional being would see 4th dimensional pistons and conrods appearing and disappearing

@@charlesfranks1902physics depends on the type of car game your playing. Arcade like games like forza and nfs wont have realistic physics, while simulation or simracing games like beamng and gran turismo (I think. Never played it.) will.
I'm speechless. Your so clever. The way you just casually created this for fun whilst being so accurate. All of the people complaining about the sound, make your own and share it. The fact it doesn't sound identical to its respective engine means nothing. For a start it gets surprisingly close but even if it didn't, it wouldn't make any difference, this is still really impressive. Not sure why people find it so difficult to pay someone a compliment.
This fucking rocks, holy shit dude. I'm down for a technical breakdown video!
Thanks! I'll see what I can do
Yea that’d be great!
Count me in! Waiting for the bell! Btw. you stated that all of this begun as you hated the sound of game engines (yeah, me too). You asked a question: why the sound is not simulated? Can you please share some conclusions? Is it a cpu/mem usage? Do you see any ideas for optimization (remove this, remove that....) to gain performance without reducing the quality too much? You made me super curious.

Here are some ideas for your project:
- rotary engine
- simulate things that interact with the engine's behavior and sound like turbos, exhaust, etc
Diesel, Turbo Diesel, waste gates, VVT, The old VW Beetle. "W" engine? VR6?
"Tunable" exhaust, From muffler, to pipe diam, and length, up to the scavenging effect of a headers/manifolds build, That would be another incredible tool for builders, and muffler shops. To be able to hear the (approx.) sound a header or muffler will make.
What abt two strokes
Exhaust would be extremely difficult to simulate…
Turbo sounds will make the simulator even more popular (the iconic "tsu tsu tsu")
Just different valvetrains (valve-in-block, rotary valves) would be nice.
This is HUGE. I always dreamed about a sim with **good** sound that'll let me build stupidly weird engines so I can check how'd they sound and now it's here. And it's free.
You're a boss, Ange. Thank you.
If you didn't, check out game called Automation. Except good sound.
@@karatas1782 Nothing like this.
Beamng drive has pretty good sounds
@@doursen Its actually pretty close as a virtual dyno. Usually within 10% margin of error of the real life engine.
@@pontiac_hat It's not that good because you're missing a ton of options. Fuel is limited to whatever their ratings are and there's no options for things like high-flow billet heads, billet blocks, huge turbos (I think their max was like 76mm front housing and 94mm rear housing), no screw blower options, etc etc. It just felt like it was made by someone who knows the basics about vehicles and not made by someone who is a car enthusiast.
tl;dr, Automation is made by a gamer for gamers, not a car enthusiast/engineer turned game developer.
Edit: I could go on and on and on about all the mechanical issues I had with the game but cba, take too long to write it all out.

@@MostafaElSakariif your against free and open source software in nay way you are actively making the world a worse place
@@happygofishing assuming by "nay" you mean "any", no. That's just a stupid position to have as being against FOSS as a concept is too.
Since you're clearly arguing from a idealigious position, let me refute you with one. FOSS is about choice, that's why linux lets you shoot yourself in the foot even though it could be prevented. Through and through, it's user choice, that's paramount, maximum choice, always let the user choose, never take choice away from the user. Great! So what if the user wants to choose something proprietary? Forcing someone to make the "right" choice is taking AWAY their choice. If you don't believe people are free to make wrong choices, you don't believe people are free to make choices at all.
The distribution model of software is just as important as for hardware. High end specialty software flat out wouldn't get the financial investments needed to develop it if it was just going to be given away for free. (yes free as in speech not as in beer, but if the code is open, that means someone can just fork it and make a free as in beer version) I hate apple with a passion, but you know what I hate more? The EU giving itself more powers because consumers are too terrified at the thought of buying a phone without a fruit engraving on the back to buy from a company that doesn't fuck them over. If the wider userbase does not like the current offerings they are free to use other offerings or make their own. If, on the other hand, people like you continue arguing that "being against FOSS in any way is actively making the world worse" and people start legislating things that directly takes away user choice. I am no longer free to buy a phone with a lightning port even if Apple is willing to sell it to me and I'm willing to buy it. Being against the very concept of non-FOSS things is being against the very concept of FOSS to begin with since FOSS is about user choice. Let me stress again, FOSS is about choice, that includes the choice to use it, or not to use it, depending on when you think it's best applicable. Proprietary offerings are what drive markets, TWS earbuds were basically fucking invented by Apple's airpods, which they forced people to use if they wanted the newest iphone. That was a shitty and anti-consumer thing to do, buuuut then the market happened and other companies made their own offerings which were better, less locked down, and more plentiful. Proprietary spearheads followed by more organic market growth to compete with those offerings is how progress works.
If you think FOSS is the only right answer, you're not pro freedom, you're just an authoritarian who happens to argue his thing is good for people... so an authoritarian. Freedom to choose, means freedom to be wrong, freedom to want high choleserol, freedom to to eat bacon and butter and buckets of cheese.
Sincerely,
I use arch btw.
Imagine if the BeamNG devs were able to implement this somehow! I think I'd struggle to ever play anything else. Definitely going to watch this again on headphones, because for me, the car sound is the best part of driving. The aural feedback stirs the soul, and if something like this can be added to EVs to play back authentic ICE sounds through a speaker, it will be a heck of a lot better than having nothing but wind and road noise with a distant electrical hum.
That is what I was thinking
Evs are a scam and more pullutant than ice cars. Change my mind.
I was impressed by the sound of the v8 engine, but when you showed the kohler V engine and it sounded just like it does at my work, I was blown away. This is seriously impressive.
Yeah I was pretty proud of that one, sounds pretty much exactly like the real engine. Thanks for watching!

Man this scratches an itch!! I always wondered why (as a kid) devs didn't just code the laws of physics into their game engines, lmao. Durr.

Same wtf and they recorded real engine car sounds for FH5 but they should have hit up this guy. Eventually we will simulate all sounds for effects as indistinguishable as real sounds!
@@carsnob yeah, right? It's such an eye opener! Also, glad I wasn't alone in my naivety 😂
@@BayLeafff no bro I was thinking the same like it was weird for me to think that it’s odd that car games have had super shitty generated sounds I wondered as a kid even! But obviously I was too young and had no real knowledge of physics or even knew that we are able to simulate physical sounds just as realistic as real world vibrations. I just wondered like why couldn’t devs just record actual car sounds as a kid or knew there has to be a way to make them just as real with computers. I bet there’s like highly advanced/complicated industrial speakers today that vibrate like real life sounds like maybe 4D sound lol idk too tired been up zonin!
Bocchi Engine isn't real, it can't hurt you
Bocchi Engine:
when we learned about engines in school, I just could not believe that pistons are spinning that fast and all 4 cycles are included, I find it amazing they can hold for hundred thousands kilometers
This is extremely impressive. Best synthesised engine noise I’ve every heard. I would not be surprised if gaming companies buy this code off you to add to their games
Probably not with an 80.000 FPS fluid simulation but you never know :D
I would expect instead they would use this to record the different states of the vehicle instead.
@@littlemrh it sounds like recording the exhaust flow wave form in various speed+throttle+horspower configurations and making a closed form parameterized function approximation out of them and then using the audio pipeline (based on the exhaust system) to create the sound itself
@@ratchet1freak Being able to enter the parameters of any given engine framework would essentially yield an identical wavelength, youd only need to add reverb to give its depth and shine depending on exhaust systems
@@arctiazarno8134 but that's only a set of audio filters, which is cheap,
it's the exhaust flow&pressure waveforms that you need to get your initial sounds that you pass through the filter. And that is expensive to compute (requiring the rigid body+fluid sim at 8k fps). If you can precomputethose wave forms suddenly you only have an audio filter pipeline to worry about
Imagine BeamNG with realistically simulated engines that are 3D
*computer explodes*
beamng can barely run its own physics simulations above 60fps on most computers, I shudder at the thought of an engine simulation
@@elllieeeeeeeeeeeeeeeeeeeeeeeee wdym? any respectable gaming pc within the last 4 years should be able to easily run beamng over 100fps. Although this sim can barely handle a 10 cylinder engine since it's single threaded so I don't think it'd work out.
@@Kevin15673 yeah but this needs 80000fps otherwise the engine will implode

BeamNG should implement this into the game's audio engine.
Edit: I didn't mean physical simulate the engine, just the sounds. That's why I wrote audio engine.
Not sure about that, but I'd love to see this as a customizable engine you could put in a vehicle.
Yes!!!
They already have some sort of it. Prob not that complex but thus not that cpu demanding. You can play with the system in "automation - car company" or smth like that I don't remember the name of the game
they would be crazy not to.
I wish the entire engine simulation in Beam was as sophisticated as this. As it is, Beam is pretty good, but also quite simplistic in some ways, so it's awesome to know that there are demonstrated alternatives. However the physics simulation in beam runs at 2000 Hz I believe, so the 80,000 Hz for this engine sim to be stable is a lot higher
wow, nice :D
The biggest compliment to this video
Here before this blow up :))
The engine sounds in BeamNG are very good, but they could be even better with this simulation, I would love to get goosebumps and start crying from the sound of the cars :)
Plus a simulation of this level with the exhaust system and I'm crying and shaking 😂
I can't believe that BeamNG actually commented on my video... this is so wild
Woah, that’s how you know this engine sim is impressive
WOW, this is awsome!!! i cant wait to look into this project more!!! there are some (and one in particular)engine configurations i have been dreaming of for some 30-40 years. thank you.
I've just found my favorite channel on the entire internet :D DUDE I've had this same thought for so long - why not just simulate engine sound in real-time? You sir, you are the one. Awesome work, keep it up!
Your side projects are entire PhD dissertations.
This makes me simultaneously happy and utterly depressed :) - Please never stop making this kind of content, it's an absolute joy.
This sounds amazing. It would be interesting seeing a rotary engine being simulated with this.
It would also be great if airplane jet engines, turbochargers and inline 4 engines are simulated. :) Also, would love tire squeal to be simulated as well.

As an engineer who made models of physiological systems in college you've just broken my brain. You've reverse engineered audio. I can feel this engine, my brain refuses to believe the actual engine isn't in your garage. If this were in a game, motor-heads could tinker with models of their favorite classic cars in a simulation and the audio feedback would make it extremely real.
Been thinking abt that in forza h5 there’s not enough difference in sounds when modding but at least they recorded real life engine/exhaust sounds. But they may have well just hired this guy lol.

This is absolutely incredible! I'm at the stage of looking through textbooks and trying to learn more about engines to see how I can simulate the torque curve accurately. Surprised that it took YT _this_ long to recommend me this video.

@@TortugaAW Anything that can rev to 11,000+ revs. I'd love to hear it.
So motorcycle engines?
There’s been numerous different engine configurations in F1 per the parameters of different F1 Eras. But yes typically they’re low displacement high rpm engines. Anywhere from Turbo V6’s to V12’s
i used the audi i5. 21k rpm. it does sound like a f1 v10
This is amazing work man! I myself would be very interested to learn how you approached the fluid dynamics and combustion chemistry in this project!
I am speechless for the great work you did its just so amazing. Keep up the good work.
this balance perfectly on being completely overengineered to an absurd levels but also being quite geniusly straightforward and almost simple
THIS IS ABSOLUTELY INCREDIBLE, I've been waiting for something like this for DECADES just like you. I almost can't believe this is real. With modern CPUs you could just run this whole thing on its own dedicated thread without any issue at all or taking perf away from anything else. I used to try physically make engines in garrysmod but the physics systems are just too jank obviously. This looks like so much fun even just to play with. Can't wait until developers start using this type of smart stuff in their game engines. Even I'm getting ideas of getting the output torque values and sounds from this and linking it up with an existing game engine somehow..
Hey it's DeSinc
didnt know desinc was a car guy
Considering that the simulation itself runs at a whopping 80000fps, i imagine that you would have to have another really, really powerful hardware to be actually linked to a game
desinc saying something genuinely smart
@@Radiation_R yeah that second piece of really really powerful hardware is called another CPU core. There's a reason why we have multi-core CPUs.
This is absolutely insane!! Amazing job dude!
Absolutely love how the engine sounds haha
Thank you! This is something that has bugged me for ages in video games, and that's getting good sounds. Just like you said, lots of in-game engines don't some quite right and I always dreamed of making something that could help make it feel right. And you certainly took the steps to make that happen!
I'd suggest getting into contact with the developers of "Automation", a car-manufacturing & designing tycoon game for the PC. They've had to source IRL sound recordings of engines for the in-game engine sounds, and then modify those to fit the many, many different ways players can design their engines. A non-ideal, time consuming and labor intensive ordeal. With your simulation tech, they can accurately create audio from scratch to fit any variation of engine, all procedurally made in-game. They might be willing to work something out with you.
Also, it would be cool to see you try simulating a rotary engine!
Automation + BeamNG having this king of sound engine would be soooo good
Many game devs record sounds of real cars into their games, but I don't know how they edit them into games. Probably just slowly rev the engine from idle to limiter and then just add that sounclip to the game and make it loop or smt
Those sounds were actually made via physical modelling synthesis. No real car recordings were used in the samples
yeah this dude definitely has a product. Curious to see if it handles turbulence from more cylinders well. Also interesting how deep the post processing is (thinking Lexus LFA on dyno v. in car with exhaust resonances)
@@ffivguy1990 How certain are you of this? As I remember a while back, one of their excuses for why they weren't going to add certain engine designs (rotary, supercharged engines, diesel, etc.) was because they would need to source more recordings for those and they didn't want to.
As a mechanical engineer student, I can safely say this is one of the most interesting projects I've seen on TH-cam. I hope it gets the attention it deserves. You're awesome dude.
Engineering tech literally just for the credits rn in country
(I hate my life I suck at math 👌🏽)
This is brilliant. Well done mate. You deserve a lot of praise for your efforts. Hopefully someone has bought this.
This is great stuff, I was so amazed to see that someone shares the exact same frustration of video game engine sounds that I have. I've always wanted to make some simulation like this and take into account the complexity of an actual engine and not just play a tone. Congrats! And also congrats on the choice of engine to start with!
Don't know if someone mentioned this before or if it's youtube compression that makes it even out, but I think this simulator will be really awesome if sound volume increased with throttle angle more. Also intake suction noise will be an awesome improvement.
Overall awesome job, I pulled the code and will try to fiddle around a little, you may get a PR soon.
it’s pretty mind boggling how fast all this stuff can go without ripping itself apart, especially given that it’s literally exploding

@@annoyingoranger100 r/confidentlyincorrect
Even if he was referring to how the engine runs it still doesn't literally explode. Only part inside the engine that literally explodes is the gasoline, but he said "how fast this stuff can go" meaning how fast the crankshaft spins or how fast the pistons move. Neither of those are exploding, they are however powered by a substance that explodes.
its really remarkable that someone would do something this complex out of just passion or curiosity. in these moments you can really appreciate what humans can do.

@@Badsniperarmy It's not ignorant. Sound (specifically the speed of sound) is affected by temperature, but only really slightly so it shouldn't matter much. The environment that the sound is in matters much more, since sound bounces off objects.

This would probably be hard to implement, but adding turbos, superchargers, exhaust pipes with different header lengths, resonators, and mufflers would be pretty awesome to see, and also would get you a super realistic sound.
Could you make this work for a rotary engine? Like a Wankel or a LiquidPiston?
Maybe an option for turbo/superchargers?

I'd love to see support for variable valve timing, variable length runners, push rod, SOHC, DOHC, and different header lengths. It'd be awesome to digitally spec out a motor and get it the way you like then build it in real life with minimal R&D.
I think the wankle engine should be easier to program since the piston itself acts as the valves, so less moving parts.
@@boltbreakgarage3842 Fuck yeah💦💧
@@boltbreakgarage3842 The possibility with a program like this could be practically endless... I think with the amount data he pulls from this simulation its even possible to calculate if certain fuels will even combust in different engine types. The fact is that it just depends on what he will do with it and how far he is willing to take it.
For example a person like TwoStrokeStuffing (fellow youtuber) could simulate an engine idea and get a resonable oproximation on how the engine will behave (and if it will even work) before putting time and efford in to build it.
This is so randomly cool! Thanks and well done! I would legit run this just for fun haha I love the engine braking noise.
This is very interesting ! I appreciate what you have made !
"A real time internal combustion engine simulation" - Okay, that sounded like a lot of work, nicely done man.
"Because I want to know how hard is it to simulate the engine sound" - wow, okay that sounded like a bit of an overkill. But go on.
"A rigid body simulator simulates the interactions between all of the internal components" - WOW okay that's even more of an overkill, right?
"A physically realistic fluid simulation" - WOW THAT's overkill
"Piranah is my own custom scripting language that I made" - gREAT now you're inventing scripting languages too. What next.
"I've actually built one of these 454 engines myself" - This man can and has done EVERYTHING under the sun.
"GM's values matches simulations' predicted values" - alright this is neat. I guess your stubborness paid off then.
"I'm very familiar with the Kohler V-twin engine" - okay, again, is there anything that you haven't done?
"Sound and horse power figures pretty much matches reality after I've entered the parameters for this completely DIFFERENT engine" - BRUH
"I literally read entire textbooks while researching this, and I've also read a lot of research papers." - Yeah man, it definitely shows!
That was my line of thought too. Absolutely mind boggling
Modern Renaissance Man
That's outrageous. I think about all the times I've watched the "making of..." videos for Forza and Gran Turismo and they have the supercars with mics at the exhaust, and here's this guy just modelled an engine and it sounds way better and more realistic than any game I've ever heard. You Sir deserve a medal. You will have project managers for game developers of those big studios ripping those guys with their mics apart. Like the comment says below I hope you get a call to buy or licence this software. Well done, good sir👍🏻
Damn they actually recorded the sounds for GT?
Forza, well the 4 cylinders still don’t sound perfect… as always
This guy, I would love to keep learning from you. Please, keep posting !
the engine stop sounds are what make it for me. they're just. so good.
This is the first time I see a physics engine being used to generate sound. Mindblowing.
This is like the most impressive thing
Damn, that engine noise is music to my ears. Well done!
I'm impressed to no end of every bit of the feat in this video, and the attention to detail. For the voiceover though I really recommend a De-Esser or some kind of multiband to tame that sibilance, your S and T sounds be whistling lol
For full realism, add subtle sounds associated with the valvetrain, cylinder walls, and bottom end!
I highly agree, that would be interesting to hear
They are already there... low and high frequency noise.
Add a subtle knocking noise that gets louder and louder with a 0.01% chance per hour to spawn
@@erdinca.2448 it mostly emulates the low and high frequency notes of the exhaust imo
Not sure whether it does already but I’d love to see it simulate induction noise aswell
this is the greatest engine simulation i've ever seen. as for your claims, this would mean we could test some modifications on this simulation first before before actually applying to the real engine? how cool is that!!
Maybe for guys doing serious piston and head work. Bigger valves etc.
I haven't seen a way to manipulate head port design or change lobe pattern and change valvetrain geometry.
Or simulate different manifold, intake, and exhaust effects.
I believe this is mainly restricted to engine noises since it doesn’t have the simulation quality for actual full on engines in the real world. If you’re looking for that, there are probably demos by various car companies showing off their latest simulation software.
As he said himself that this is meant for video games and not professional engineering software.
@@DannyLeWasTaken really? I totally wasn't aware of that. Thanks for mentioning it.
I just found you via your Steam Engine Simulator on Steam. You're insane.
This is genuinely great, I love engineering more than just cars so even in games my focus is towards the technical side of things, sounds beinf somewhat a part of that and I hate when cars dont have the sound that conforms to the engine it has and the way the engine behaves under load. Especially hate it when LICENCED cars don't sound like their real counterparts.
As a gamedev student planning to go into the racing sim industry you've also made my job somewhat easier. Got to say i'm very grateful for this software.
Having done audio development for vehicle based video games over the past 20+ years, this is the first time I've done a double take when it comes to a purely synthesised internal combustion engine. Massive kudos for what you've done here......
Next this guys gonna be like “and actually during this project my computer crashed so in order to counteract this I made my own operating system and had to hand make my own computer from scratch the hardest thing about that was the gpu with how much optimization it needed but after that the one to one universe simulator ran faster that ever” also I would love to see the technical side of things so I’ll definitely stick around for that
Yeah , i was amazed when he said he made his own scripting language
yes i'm interested as hell in technical details, i'm sure i can learn something new! also this is so freaking cool, this is way beyond most of the things people do just for fun!!
I am 1000% interested in technical details! Your earlier video on general physics engine design was so helpful to me when making a boids simulation in Rust. Love this type of content
This V8 engine sounded much more life like then I've ever heard, I'm sure 12 cylinder radial engine would sound impressive.
"Quite possibly the dumbest project I've ever undertaken" This is INCREDIBLE! Cars and engineering in general have always been in my area of interests, and imagining every component of the engine, transmission, diff, all working together at once, every gear, oil pump, etc is fun to think about. Was always wondering why no one had done this! (accurately simulating each part that is, maybe Automation but the sound isn't there like it is here). Would love to see this implemented in an actual game like dirt rally or BeamNG. Definitely make a breakdown video!
Sadly, I don’t think it’s possible to simulate in BeamNG since his simulation runs on rigidbody at like 80000 fps but hopefully one day.
@@SpaceGood. for sure, neat to think about though, when computing power becomes powerful enough and common enough for the consumer to experience this
@@kianmcgavin7659 oh really? That's super cool!
Well I think beamng actually already provides great engines sounds
Haha V10 go brrrrrr
I would for one love to know the intricate inner workings of how you came about to build this sim! The research papers the textbooks, the whole 9 yards. Obviously summarised for the video!
This is one of the coolest things I've ever seen in the realm of simulated cars. It took me straight back to being under the hood of my El Camino, pushing its throttle open by hand to hear the brand new 350's engine noise, and the sound coming out of its dual exhaust (with headers!). Damn, I miss that car right now...
Absolutely amazing. This is rare - someone with great aesthetic sense and skills in programming, physics, graphics, and communication. And the willingness to share knowledge. Congrats!
This makes me feel so dumb. Even though I studied mechanical engineering this is something I could only dream of making myself.
Arguably the coolest video ive ever seen. Good job man
This is nuts good work!
The amount of different skills required to write this stuff is simply amazing. You wrote your own scripting language, you know about sound processing, physics simulaton, mechanics and so forth. And here am I, not even being fluent enough in english to even describe how amazed I am. Mad respect bro!
