You have to have good enough air flow (volumetric efficiency) at higher RPMs, which typically requires modification of the valvetrain/cams. Also the valve springs need to be strong enough, and be able to last through many rapid compressions. The materials also need to be able to withstand the added friction.
The valve timing is connected directly with the crankshaft (geared to the camshaft) thus the timing shortens as you reach higher RPM. You would likely however need cams which open the valves a bit more to allow for greater airflow.
Every time I see the EE videos I'm impressed by, 1) The knowledge of this young engineer put into down-to-earth terms and, 2) How much he looks like George Harrison (my favorite Beatle). Thanks for sharing. Keep up the good work. God bless.
I like the fact that he doesn't mention about Freeing up Exhaust pipe, some people do that and get so little to nothing, making so loud noise and car still moves so slow. The young men above is on the right track. I could hire him to work on flying vehicles in the future, as soon as I stopped the crooks.
Great, thanks for checking out my channel. If you're just getting started, I'd recommend starting with my website howdoesacarwork(dot)com. I have lessons set up in a logical order to get you started; start with lesson 1 on engines. Also, I have a video on my website, and all of the information it provides, search youtube for "how does a car work website" and look for the video by EngineeringExplained. Thanks for watching!
Sounds like you're more organized than I am! I have my notes scattered about on my desk, on individual sheets. Glad to hear you've found the videos useful. Just send me a PM with your video whenever and I'll check it out.
If you really think this video is inaccurate, you clearly have no understanding of internal combustion engines or physics in general. This video is spot on.
It doesn't let out less exhaust, it's turns the heat of the exhaust into useful energy, thus increasing the efficiency of the engine. The answer is yes, but many turbos are there for increased power, not necessarily for the most fuel efficient cars.
Okay, confession time. I know NOTHING about engines, cars, pretty much anything of that sort. This is only the second video I've seen and I feel so informed! It's put into terms I can (for the most part) understand. I'm getting ready to get my first car and I need some stuff explained and this has helped tremendously! You're doing fantastic, keep it up!!
+Tony Cruise not to maximum, at higher speed tires get hot will. break depends on how fast is it. and the other way around if upu have too much air they will have less surface area to the ground so from stop to going might spin your tires depends on ypu have lots torque. fill air a couple psi less than the max tires pressure
It's not the "downforce" that the engine has to compensate for in order to accelerate, it's the drag. A 1000 kg car with 1000 kg of downforce still only has to accelerate 1000 kg of mass, not 2000 kg, however it has to compensate for the additional drag which will be significant.
These videos are just in time!! I'm working on a Porsche 944 for a track day car! Doing a good job and these and you actually know what your talking about! Keep it up!!!
Spoilers increase downforce, thus increasing the maximum lateral g's that a car can hold (check out my video "traction circle" for more details) and allowing the car to go around corners at higher speeds.
I got to say, I have never seen a better explanation of horsepower. Honestly, at first I thought you were young so you didn't know much, but in fact you blew my mind away, thank you so much for your amazing explanation. I am also very grateful that you used formulas, because I'm more of a book smart kind of guy. Thanks again.
i have only taken short peeks at a cpl of your vids and while i understand everything from the "i know how to make horsepower from years of doing it" end i hope you are trying to explain it so that people with no background in automobile mechanics can grasp the concepts. keep up the good work m8 :)
I swear, I have learned more about engine performance and suspension than like a year of scouring forums with flame wars. Your videos are very informative and the pictures make it so much easier. Thank you so much and please keep up the great work!
i am a graduate mechanical engineer, i got a entry lvl job dealing with Heavy Equipment..and all you vids help explain a lot man. honestly, if my professors were like u, i would hav gotten 1st class honors! ur vids are clear and explanations and diagrams are excellent. i hope ur a lecturer somewhere. hehe
It's not something you typically modify, but would require new cylinder heads/valvetrain for modified air flow at high RPM. And of course the strength to cope with higher RPM.
Usually a cam will give your engine the ability to make more torque at higher RPM, which means more horsepower. Your engine needs more fuel and air as well, which your stock computer (assuming you have EFI) may or may not be able to compensate for. It's always good to get a custom tune when you are drastically changing your engine's power.
No, I mean an overall reduction in the heat created at any moving contact points. For example, with the new CR-V Honda reduced friction by about 5-10% along the drivetrain, which was good for a real world increase in power.
Horsepower at a given RPM is defined by your torque at that RPM, divided by 5252, times that given RPM. If your car makes 250lb-ft of torque at 3700RPM, you make 176HP @ 3700 RPM. If your car makes 250lb-ft of torque at 6200RPM, you make 295HP @ 6200RPM.
Hey I just wanted to say your videos are perfect. I had the most basic understanding of cars. But through your videos and applying what i learn to more complicated things about cars it helps out. I have like 95% of your videos and diagrams in a notebook. Im gunna make a video showing you the notebook. Your videos have helped me in some of my physics lessons in school, and my auto teacher is very impressed by the notes I've taken on my own time,Thank you and hope you watch the video I put up soon
thanks for the useful info: this explains the crank shaft angles to increase engine RPM (2016 Honda - CRF 1000 Africa Twin), reduction in weight of the engine in modern cars, reduction in weight of transmission, transfer case, drive shaft, differential and half shafts; and maybe the overall frame and body weight.
For the first part we use the term BMEP, brake mean effective pressure. In short raising BMEP or CR or RPM will result in HP increases. Reductions in friction do not effect HP, they effect BHP which is Brake Horsepower that is measured at the crankshaft where HP is the calculated theoretical value at the combustion chamber.
I love how sometimes you say " hello everyone and welcome!!" And your really upbeat and we can tell your happy but sometimes you say it and sound really tired or like you just woke up and haven't drank coffee yet
+Engineering Explained yeah that explains a lot. I love your videos. Have you ever thought on making one about why you should or shouldn't polish your intake to get more airflow? I have a engineering teacher that says they used to polish everything air came into contact with inside the engine to get better flow but later discovered it wasn't as beneficial as they thought it was. Just an idea but thanks for replying.
A very popular topic when talking about cars is whether coasting downhill in neutral is more fuel economic that coasting downhill in gear.. In my opinion we should always coast in gear because: - you have more control of the car - the engine rotates thanks to gravity and without fuel being burned Would you make a video on the topic? Thanks and keep up the good work..
Omg if i had a billion dollars i would hire you because i have a car design in mind and i need the best of the best. You my friend are something special.
great video majority of great teachers do their best 2 explain 'how" things work. B/c of time constraints, bombarding w/ info can be counterproductive. leaving you 2 sort out the important. teachers forget important lessons. "Why" something works, and WHY it needs to work. Any1 can learn how something works by working on a part; taking it apart and rebuilding it. u become a better mechanic if u know the reasons why the parts work in that particular manner, n reasons why u r taking it apart.
I think using the mathematical formula for brake power could make this a bit more clear BP = Engine displacement x F/A ratio x RPM/120 x LCV of fuel x Air density x volumetric efficiency x mechanical efficiency x indicated thermal efficiency. By analyzing the equation you can easily figure out the parameters that can increase engine output
Internal Waste gates are built into the the hot side (exhaust) of the turbocharger. these are found mainly in factory turbos. External bolts up to a flange on the exhaust manifold it self and regulates the exhaust flow from there. They are just to different ways of controlling boost pressure. with a manual or electronic controller.
Great video. But you can actually increase grip in the tires by putting more weigth without the car weigthing more. This is easy to do in cars with the traction on the rear wheels and in drag racing (1/4 mille). All you have to do is two things: 1) put very soft bound settings on the suspension, so when the car starts to accelerate, there will be weigth transfer to the rear wheels very fast and easy. 2) set the rebound settings to the maximum restriccition possible in the rear suspension. This will prolong the effect of the weigth transfer, from step 1, for long time, giving you a lot of grip at the rear wheels.
change the material of the piston to something lighter weight, but also something that can handle thermal expansion and explosions. Also you can add better rings around the cylinder.
Please don't put so many spaces in your comments. Anyways, yes, you don't want hot air fed to the engine, cool is more dense. Sport headers may have a different design or greater area to pass air through. Check out my video on increasing power with the exhaust (search my channel).
Great videos! Love 'em, and you've got yourself another subscriber.May I suggest a future topic? In designing an engine, how do you tailor its torque curve -- flatten it our, peak it up, change the revs at which this happens? Also, why you'd want to do it: what performance / handling / economy characcteristics result from a given torque profile?
Not sure, punch in the tire size on a tire shop website; they should have reviews and traction ratings for different tires. You get what you pay for :)
Hey man! I'll try to keep this short. The reason why A/C robs your engine performance when it's on is because the A/C Compressor uses power from the crankshaft via the belt once you turn your A/C on. The reason it only robs your power when you switch it on is because the clutch from the compressor is only activated and pulling the compressor via the belt when you switch the A/C on.
Hey Jason, great material bro, I've learned a lot from you already! I have to admit I didn't know much about how a car works until I came across your vids. I have a couple questions for you though. How much does engine displacement have to do with the total amount of HP that can be produced by an engine? What are the differences between engines in Japanese, American cars, and Euro racing cars? What technology do these engines share or have similarly and what is different? If you could someday make a video explaining different engines (K series, B series from Honda, Mitsubishi/Mivec, Domestic engines) and what each kind of engine is the best at in terms of performance as well as comparing them to the other engines overall performance, that'd be awesummm. Cheers bro, thanks for the awesome vids. Keep 'em coming!!
bigger displacements means all the cylinders have better torque, which have fast speed from stop to go. Thats why dirt bikes only have one cylinder.if v8,v10,v12 have the same cc, than the v8 has has better 0-60, v10 in the middle and v12 less. but v12 has more smaller cylinder means later on the top speed will catch up. but if the v12 has more hp it will go gaster from stop to go. hp and torque work together.
The point of maximum RPM is determined by the maximum amount of air which can be drawn into each cylinder, after that the engine will choke itself. This is given as: Max Power RPM =Ci×(πD^2)/2×210×Duration/360×60/RPM. Therefore increasing valve diameter, valve lift, valve duration and increasing your flow coefficient will increase max power. Also pulse tuning will help however high lift cams on not VVT road engines is not a driver friendly option!
Tires witch have a larger diameter increases your maximum speed, not the frictional coeff. Friction coeff is a mixture of all sorts of parameters, like road characteristics, tire construction and characteristics...
Increasing your maximum rpm might not necessarily increase the acceleration of your car. Usually, in naturally aspirated cars with electronic fuel injection, the available torque drops towards the redline below that of what is available by shifting into the next gear. In some cars this may not be true in 1st or possibly 2nd gear, depending on the car. It can be done through ecu tuning, to raise the limiter but runs the risk of shortening the lifespan of the engine run at higher revs for too long
driving with a low amount of fuel increases speed because the car is much lighter, i can literally feel the difference in my car when my tank is almost empty compared to when i just fueled up
The 1-6 guys missed a few things. Strong lightweight battery, upgraded fuel pump, oil cooler lines, bigger fyel injectors, not just cold air but a larger intake manitold sysyem and larger throttle body with better mafs. Upgraded head(better valves and cams with stronger springs etc. Machined head for increase compr ratio, yes to the lighter pistons and stronger connecting rods, better oil pump, them arp studs removing power steering and ac, better belts, better fuel rail. Etc..etc
No worries. In practice, it's just easier to buy a car that has more power, or that has been modified to your liking. Usually v8's or forced induction like supercharging or turbo charging is the way to go. There is so much to know and each car is different
I graduated as a mechanical engineer.
Best comment, love your video. Amazing attention to details.
Congrats m8
Congrats
that's somewhat wrong. O2 makes HP, spark ignites fuel, fuel + compression burns O2. more fuel doesn't make HP.
@@FloydODB you need the right mixture, if you have more of both you will make more horsepower.
You have to have good enough air flow (volumetric efficiency) at higher RPMs, which typically requires modification of the valvetrain/cams. Also the valve springs need to be strong enough, and be able to last through many rapid compressions. The materials also need to be able to withstand the added friction.

He might be a Vulcan. Can't see his ear tops. How come he didn't utter the actual term for the coefficient of friction: Mu?!

Instructions not clear enough cracked my pistons.

Ethan Heisse hmm.. well why did I eat mine then?
That happened because you increased compression but your pistons couldn't handle it
he said assuming all else is equal, power always comes at acost
Ethan Heisse COMMENT DESERVES TO GO IN THE HALL OF FAME.
Just a note, that'd be maximum theoretical speed based on gearing. Horsepower and air resistance will likely be the limiting factor.

Smh everyone knows a stripe over the top of the car adds 100whp, pointlss video...
Jack Hobbs fake hood scoop 50whp add racing stripes 50whp add fake turbo whistle 150whp. 😂😭😂😭😂
Or adding an M badge to a 3 series gives you an extra 40hp, same with a non AMG Mercedes, as long as the badge is there you'll get the performance.

I love you bro , that was the only key missing form my project !!!! I will never forget that

Yes, and your logic is correct. Greater downforce means a greater cornering ability.

Thanks, my apologies about the sound! Perhaps I can try opening a door and see if that helps cancel out the echo.
Thanks, will do Yohann!
Both essentially are referring to the friction between the tire and the ground, so I'd call them synonyms.
Perhaps, depending on what information I find out. The principle is fairly straight forward though - increase displacement -> burn more fuel.
You are by far coolest person on TH-cam!!!! Love your content
F = ma, correct. "m" is mass, and the mass of the car does not change with more downforce.
I love your videos Jason.You know you are a good teacher when you can explain a difficult subject in laymen terms
I've been watching your videos and they're pretty cool and helpful ! Thanks for posting these
We'll see. It's pretty innovative so I do like that.

Not sure what you're implying? AWD does allow you to put more power down, yes. That said, it also has more losses through the drivetrain.

Not a bad idea. Friction, flame propagation, air flow, inertia. Probably numerous other reasons.
Weight distribution and balance is important, yes.

You're good! Keep it up, man.
It's Jason. Pretty frequent question, check out the FAQ's on my website (see link in video description). I drive a 99 integra ls.
Superb,short,clear and understanding, thank you!
Very useful videos, well explained and directly to the point. Thanks a lot!!

Thats why dirt bikes only have one cylinder.if v8,v10,v12 have the same cc, than the v8 has has better 0-60, v10 in the middle and v12 less. but v12 has more smaller cylinder means later on the top speed will catch up. but if the v12 has more hp it will go gaster from stop to go. hp and torque work together.
Idk why but every question I’ve had today has been on your 10+ year old videos
The point of maximum RPM is determined by the maximum amount of air which can be drawn into each cylinder, after that the engine will choke itself. This is given as: Max Power RPM =Ci×(πD^2)/2×210×Duration/360×60/RPM. Therefore increasing valve diameter, valve lift, valve duration and increasing your flow coefficient will increase max power. Also pulse tuning will help however high lift cams on not VVT road engines is not a driver friendly option!
Both, as they are very connected.
Tires witch have a larger diameter increases your maximum speed, not the frictional coeff. Friction coeff is a mixture of all sorts of parameters, like road characteristics, tire construction and characteristics...
This actually make sense to me now cause I felt power increase on my car but wasn't sure if it was just my imagination and your explanation is good
yeah, it was just your imagination.
Wow such a wonderful explanation...THUMBS UP
Increasing your maximum rpm might not necessarily increase the acceleration of your car. Usually, in naturally aspirated cars with electronic fuel injection, the available torque drops towards the redline below that of what is available by shifting into the next gear. In some cars this may not be true in 1st or possibly 2nd gear, depending on the car. It can be done through ecu tuning, to raise the limiter but runs the risk of shortening the lifespan of the engine run at higher revs for too long
driving with a low amount of fuel increases speed because the car is much lighter, i can literally feel the difference in my car when my tank is almost empty compared to when i just fueled up
