NEW VIDEO EVERY WEDNESDAY! - ยานยนต์และพาหนะ
Hey mate I need someone to fill in as a lead guitarist for my Beatles cover band. You'll fit perfectly as George Harrison.
He's busy starring in the new lego movie.
This is why I love the internet!
@@tedcrilly46 the coment was great but your Answer... I just Died!!! thank you for making my day!
LMAO !!!
If Friends were to have a remake and they need someone to play Ross from the past then... 😁
Thanks for the general info. All of these things were the muffler to me until I watched your video. 😂
Yea bro to this day I thought, that exhaust is one long pipe with muffler at the end. Guess not 😂😂
Same 😄
*"How old are you?"*
*"somewhere between 17 and 75"*
A tip : watch movies on kaldroStream. Me and my gf have been using it for watching lots of of movies recently.
@Enrique Quinn yea, been using KaldroStream for since december myself :)
@Enrique Quinn yea, I have been using KaldroStream for years myself :D
Thank you Jason. I recently replaced my stock muffler with a light stainless steel cat-back exhaust system with 2 and 1/2 " dual piping. It made a notable difference. I wanted to get the Titanium Cat-back exhaust like the Focus RS but it was not available.
Still, it's lighter than the stock. It sounds much better with that low-end growl. Most of all, I've noticed an increase in both horsepower and torque. Because it's equipped with a resonator, it's louder but not too loud. Thanks again.
Nice video I learned more from this video then I do at my shop
Or the fast and the furious movies 😅😅
Me: Trying to peacefully sleep in my room with the lights off
My sleep paralysis demon in the corner watching me: 0:00
Thanks! Glad you find the videos helpful.
you're awesome, i took all the sciences / engineering classes in school and they just seemed to ignore mechanical engineering, your video's are like a school to me, great job, looks like you don't really need school after all, just need the grades to get to univercit (over here in england any way)
People don't enjoy loud exhausts? Who are these heathens?
+Lee S I enjoy loud exhausts on a short drive or on a mountain cruise, but if my 4-banger econobox sounds like a racecar on the way to work it will start to get old pretty quick.
+Lee S yeah imagine how enjoyable it would be if it sounded like a NASCAR race every time you drove anywhere, it would get old fast.
Lee S Liberals
You may try removing your entire exhaust including the manifold and I promise you, you will undo that pretty quickly.
My neighbors
Correct, it's simply used for determining the CAT's efficiency. It is not used in adjustments for the A/F ratio (this is done by the first O2 sensor).
you dont want it to be loud?!??! THATS THE WHOLE POINT ;D
PEOPLE (aka my neighbours) don't want it to be loud. Car guys want it to be loud.
I kinda knew, but didn't really know. This was very helpful!
I may one day do a motorcycle playlist, yes.
I appreciate the thought! Maybe one day someone from Dubai who's confused will ship me an exotic. :)
🤪
In your opinion does 2 exhaust male more power than single what you think
Aahhhhh it’s been 10 years since this one came out 😅
That's what she said 😂😂😂
I WOULD LIKE TO THANK YOU , FOR ALL EFFORTS YOU MAKE . WISH YOU SUCCESS , IN ALL ASPECT ....... AMAZING PERSON
Many thanks for this video.
I already knew what an exhaust is and all the parts and I still learned in this video 👍🏼
These little vids always help
Love that car, would love to have one. No idea honestly; if it's in great condition it'd be an awesome car to own. That said, it could be a difficult car to maintain just due to how rare it is/parts availability. I'd chat on some NSX forums to see what people think.
Great upload! I love watching the videos from your channel, they are very clear and I always learn new things.
What sort of cars have a resonator? Sports cars, or luxury cars, or do all modern cars have them now?
I’d really like to see a performance resonator video
I suppose I could, though it's fairly simple so I'll try to describe. Basically you just take the volume of one cylinder when the piston is at it's lowest point, then subtract the volume of the cylinder with the piston at it's highest point. Then multiply this number by the number of cylinders. This will give you the engine displacement (the volume that the pistons displace) aka engine volume. You can calculate it simply by taking the bore and stroke, and finding the volume of the cylinder.
I paused after he said you don't want it loud, i'll find another video.
Good Day Sir!
I said good day sir!
love your work EE, my go to place when i need to know something, thanks for the excellent effort!
Love your videos.If it wasnt 4 u i wouldnt have a good understanding on automobiles.Looking forward on the muffler video, like how u added ur car as example
hi jayson. may i ask the pros and cons of deleting an egr system in diesel engine, theres plenty of vids out there but your explanations is the only one i trust. thank you
Wtf he should've been my instructor in high school
Yes, and really shouldn't damage the engine. But it's illegal in many states unless you're only tracking it.
Glad to hear it! You may like my second set of playlists on my channel, I've ordered most of my videos logically so you can learn them in a manner that everything makes sense.
your drawing was really good
can you do a whole video on EGR systems and if a delete is good
On some vehicles with Exhaust Gas Recirculation (EGR), the system functions off of the back pressure of the exhaust system. If you put a more free flowing exhaust system on, the EGR may not function and that COULD cause engine damage due to high internal temperatures during cruising speeds (speeds where EGR would be in effect).
nice vid, looking foward to the follow ups! cat converters something that will be pretty cool.
Loving the recent basics videos you've been doing, have to say some of the more complicated videos are a bit beyond me atm. Basically - More BASICS please!
I love all these vids thank you
Do a video on straight pipe
Straight pipe is exactly that, no interference (hence no cat).
I'd love to see a video about Helmholtz resonators!
A video on the main differences bewteen a diesel and petrol car, what does one have that the other doesn't etc would be good.
Yes, he has majored in mechanical engineering
The ignition timing is fine with an exhaust. If you up the a/f outside of the correctable range (ECU's will only correct A/F to a certain degree based on O2 feedback) then it'll run lean and then long term lean conditions can lead to engine wear. That's A LOT, though. You typically won't find issues with that unless you're running carbs (as they can't automatically correct A/F). Typically O2 sensors allow like 20% A/F correction, you likely won't see that w/o flow mods (cam, heads, intake, etc.)
thanks for that quick summary
The new look works great!
Basically how rigid the car is, in a corner a stiff chassis won't flex, and the car will remain stable (depending on the suspension). A soft chassis may mean the body can flex a little bit, which isn't desirable. This is why convertibles has strengthen chassis', to make up for not having a roof.
Your videos are very informative and interesting. Thanks for making them! Keep up the great work!(:
It means the chassis is stiff enough and has good enough handling to withstand the power of the engine. Pretty much, the chassis can stand up to the torsion of the drivetrain and keep the tires on the ground firmly planted for maximum grip on corner exits.
I wouldn't say there's any rule like that, but it would depend where the O2 sensor is located. If it's a V8 and the O2 sensors are located in the headers before both sides join (not sure why, but it could be done) then there would be two. It's likely that that they would just put it where they join up though. As for the rest of the exhaust, the number of cylinders wouldn't matter. A 2 cyl and I6 would have the same amount.
i think u should a heat wrap vid and keep up the good work!
love ur videos ..ur very bright...i am a mechanic too so i know my stuff,,well done
I always wanted to know this when I was a kid. Thank u
Thank for your tutorials
I believe they're common in many different types of cars.
A very wise mechanic once told me that he had never seen an engine performance problem if a downstream (after the cat) O2 sensor was not working. Presumably that distal sensor just assesses the cat efficiency. On newer systems, is input from the distal sensor used for anything other than that?
Your videos are fantastic. Would you be able to do some on motorcycles and the physics/engineering principles that surround them?
good video, explained very well.
Perhaps, I'm not much of a sound guru so I wouldn't be the best to ask. Maybe some one on here will have a better understanding.
You may have misread his statement, he's saying he'd buy one for me, not that I should buy one. I do want a new car, but for the time being cannot afford what I'd like. So I shall wait! It's a true statement nonetheless, cars are not wise financial investments - they're just fun.
I guess that the torque wouldn't ruin the chassis and the forces involved would leave it intact. Unless they designed it, or tested it, it's likely just speculation. I've heard the transmission can handle 700 hp, who knows. Eventually I'll get into that scene, and plan on making the results very clear.
Be sure to get some WD-40 or PB Rust blaster or similar, it will really help get those rusted bolts and nuts out and off, also depending on how badly rusted your exhaust is you may have to cut stuff off, may also want to replace your muffler and exhaust hangers.
Thanks this has givin me at least a general idea but I was wondering on street cars how do they purposely make the exhaust loud?
Thanks for this short a informative video!!! Hi (I don’t know much about cars) …I notice that there is gases escaping from the resonator… is that normal…!?! Thanks!!!
Yep.
Will you ever go into the science of racing? Maybe do a second channel called racing explained? How about tuning explained as well?
Check out my F1 playlist, probably have some additional material like this soon.
it's a second O2 sensor. if it fails for the converter fails you won't be able to pass emmissions testing. On new cars they just plug in a code reader to find out if you pass, on older cars they will actually probe your tail pipe.
March of 2012, yes.
Great video man.
I've only got two really on my car, one replacing the distributor cap, the other replacing the thermostat. It's become apparent I need to upload a video simply covering my car.
Can you make a video on how manufactures tune for the exhaust note they want, for example like how they did with the LFA
So helpful! Thank you!
You wouldn't legally be able to drive your car in the majority of states. But if it's just for track use, I suppose you could see some power gains. Do the right thing, keep the cat, or get a high flow one!
Engineering Explained personally i feel id prefer to have a cat. Maybe backwards for a jeep driver. But we have a responsibility to take care of this planet and the animals
So glad i subscribed
No shouldn't be difficult, maybe some bolts that don't want to break free, but that's about it.
What is a resonator?
How it works?
clear explaination😄
is there a benefit to a tubular manifold rather than cast manifold for FI?
love the videos as well! thanks.
thanks for letting me know & thanks again for all the great videos :)
First I would like to thank you for how much I've learned with your videos. My question is, I remember back in the 90's, the legendary acura NSX had two large tail pipes, and the nissan 300zx had 4 smaller tail pipes. If both had the same HP would the exhaust system make them different?
Search my channel for "traction circle" and "drifting", you should find what you're looking for.
Awesome! :)
hi,
thanks for the great videos
i often hear some commentators say that this chases can handle up to 1000hp and so but what does that mean?? and what happens when you cross the limit??
i think chases engineering would make a good video
Your suck an engineering nerd. Love it!!!
Hmm, that was done by Yamaha's musical division, quite beyond me. But a cool idea.
Me too
Easier said than done, but I'm working on a few. Let me know if you have any contacts! I do have a video with a nitrous kit from Nitrous Express; should have a catback coming as well soon.
I'd like you to talk about how modifying your exhaust can shorten engine life. I've heard that when exhaust gases find less resistance than the engine expects, it runs maladjusted and you can damage the exhaust valves. And I'm guessing it ruins the whole engine timing... but I don't know if an adjusted ECU can "teach" the engine a new timing according to the modifications (but that can overstress internals), and for carburated cars without electronic management I totally don't know what happens.
Cost, bought this car 6 years ago. I do need to film it eventually.
I still watch this.
Hey I'm a student mechanic in MA and your videos are great but the heat shield still on when your trying to show what's under. If you could please for the viewers actually show that piece or part shall I say that you are speaking of right in view thx
I believe most diesel engines do not have cats. DPF is a good idea for a future video.
You mean if they both had the same engine, or same hp? Yes, it could make a difference, depending on the total area of the pipe allowing for the gases to leave. If they have the same hp, then, well, they have the same hp.
Hi! Please explain EGR on diesels. Is it good or bad thing? And does it right to turn it off???
heyy does removing resonator effect the fuel consumption?
Hi thanks for the nice videos :)
would you mind explaining going faster on the corners?
and when cars go sideways please
Can you make videos on exhaust system fundamentals?
EE.. i have avrequest.. please Make a video on "straight pipe problem". Discuss on what are the effects of doing so on car performance, pistons, pipe etc. coz i found out after sometime, my engine just got a major overhaul coz the engine block just got bigger and i got to skim them and use oversize piston. Plus theres so much carbon deposits on the pistons. Wonder are those really are the problems that might occur when using straighten pipe. Thanks for the consideration 🌻
I really hope you can answer my question. I looked on youtube to find an analysis of an f1 car exhaust sound and one of a acura nsx. The f1 was a really high frequency 500-720Hz while the NSX's had a range of 250-300Hz. Since F=velocity/wave length is it possibly to put a smaller diameter exhaust on a nsx or any car and increase the exhaust velocity to increase the frequency therefore making it sound more like an f1 car or at least a farrari.
could you please make a video on "performance cycle of an ic engine" or performance parameters
Do you have a video showing exhaust pulses in the exhaust? The back and forth
