  1. hi, i would love to know what liters in engine terms mean.

    ReplyDelete
    Replies
    1. Liters simply refers to the volume of all of the engine cylinders. The useable space there is to make power.

    2. ahh thank you, i couldint find that anywhere, keep up the good work :)

    3. 1 liter=1000 cubic centimeters. This is easy way to go :)

  2. first of all i would like to thank you for your all the videos as learning from your videos is fun and concept can be cleared faster as compared to reading theories.
    My topics of interest are:
    Multi-link suspensions as well as AIR SUSPENSIONS.
    Also i would love to know about Hemi-Engines.]
    Thank you

    1. I will add the suspension videos to my list. As for Hemis, search my channel for "Hemi Engine" and that should help you out!

  3. Hey, I have an 2002 v6 Mustang convertible,what do you think are the cheapest, most effective ways to make it faster off the line? I could care less about top speed to be honest. I started watching one video you had on turbos, and then found myself spending the past 4-5 hours watching them all! Great job explaining man!

    ReplyDelete
    Replies
    1. Top speed basically comes with making a car quicker, if the solution is adding power. Improving acceleration can be done in other ways though. I'd recommend reading some forums about people removing weight from their Mustangs, see if there is much that can be reasonably removed. Also, if your wheels spin when you launch, then finding a better set of tires would also help you out.

      Delete
    2. Using a low ratio differential will help get off the line quicker..

      Delete
    3. Tyres with better grip will be the cheapest and easiest way to increase your acceleration every time, also you can lower tyre pressure thus leading to a greater contact patch on the road but this can strip the tyre off the rim. Suspension as well as power is lost when suspension squats down.

      Delete
    4. He drives a Mustang V6, this is no performance car! I would try to use a limited slip differential and then use much more smaller tyres with high pressure to reduce rolling friction. you may loose some 1/10 seconds from 0-30, but after this point the acceleration will rise because you have not so much loss from the drivetrain with smaller tyres ;-)

      I would recommend to use 195 oder 185 tyres and 3bar tyre pressure. Most of the show and shine guys don't know what you have to do to get a faster 1/4 Mile time with cars that have no so much power.

      That's why Top Fuel Dragster use small tyres on the front wheels - because they can make the cars faster with less rolling friction.

      The show and shine guys roll on 20 Inch Wheels with 265 Tyres. This is bullshit and just for show. For Track racing you need thicker tyres but they also need to be smaller, 16 to 18 Inch Wheels will work fine on a mustang for track racing. and for better accelerarion too.

  4. I've seen your carburetor video and is so good but I think it would be a good idea to explain the diferent types of carburetor and where are they most commontly used (cars, bikes, airplanes, 2stroke, 4stroke)

    I think carburetors divide on fixed venturi(the one explained in your video) and variable venturi. Within variable venturi you can find the conventional ones and the CV (constant speed)

    look on this site the 4.0 Operation

    http://en.wikipedia.org/wiki/Carburetor#Power_valve


    and watch these videos:

    http://www.youtube.com/watch?v=T_7d1FxZD8U (variable venturi-conventional)
    http://www.youtube.com/watch?v=7cb2CbIfDeA&feature=relmfu (variable venturi-CV)

    take your time!

  5. Hey, could you please explain tire sip angles? Thanks in advance.

    ReplyDelete
  6. Hi. Perhaps you could do a video explaining the smaller parts of a car's engine: ex. harmonic balancers, freeze plugs, various bearings and journals, rocker arm assemblies, and the such.

    ReplyDelete
  7. It would be nice to see a video on stroke and it's effects on torque, etc (seems like diesels have larger strokes and more torque)

    ReplyDelete
    Replies
    1. based on your observation my intuition tells me this: if you look at the crankshaft through the flywheel it will describe a circle when it rotates. The diameter of that circle would be the stroke of the engine. From physics you can easily deduce that the longer the arm length the greater the torque applied. So diesel would produce more torque because stroke is greater => crankshaft diameter is greater => torque applied on the crankshaft axis is greater.
      However if you look at Renault Megane Sport R26R 2.0 Turbocharged (2006) petrol engine vs Renault Megane Sport RS 2.0 Diesel Turbocharged you will notice this:
      - The petrol version produces 228hp 228lb-ft (310Nm) torque with 93mm stroke
      - The diesel produces only 170hp but 264lb-ft (359Nm) torque with 90mm stroke (less stroke, hmm)

      Way more torque for the diesel. What actually gives diesel fuel it's torque is 1: compression ratio is higher (9:1 for petrol, while diesel has 16:1, almost double) and 2: (less significant but still) diesel packs more energy per volume than petrol.
      Hope everything makes sense and if I'm wrong someone please correct me.

  16. Hi Jason,

    I wanted to first let you know that you are a blessing! Thank you immensely for all your time in making these videos that we can learn from. Your generosity with your time is so encouraging, and the amount of things I learn for free from you is astounding!

    One thing I have been wondering about is how exactly dynos (dynamometers) work and, in turn, speed the gear up to match the shaft. I do not know if you had included it as a subtopic in a transmission video and I missed it, or if you have not mentioned it at all. Would you please consider a video related to this? Even discussing it briefly in another video would be extremely helpful.

    With Gratitude,

    Jordan

  17. Great videos, i have watched many of them and you really do have a great way of simplifying how so many different things work, i linked one of your video's in a guitar forum in a section for for other things not guitar related.

    I would like to see you make a video about electric guitar "pickups", more though about the pickups "pole pieces" and what actually happens(scientifically/electrically/magnetically, and the resulting alteration in tone) when they are adjusted upwards or downwards, i'm not sure if this may be in your field but it's a grey area for many guitar players and any info. on the matter would be of great interest to many, thanks, Stephen.

  21. Hey,

    I really enjoy your youtube videos. I too am a Mechanical Engineer, but I have only recently gained a specific interest in
    auto-motives in the last while. I searched your site and was wondering if you could do a lesson on power band. More specifically why a vehicle is more inefficient operating outside this RPM range as well as examples of various types of cars and their different power band regimes.

    ReplyDelete
  22. Could you do a video about how all car components are linked together? For example turning the key engages the electrical components which engages the starter and the mechanical engine and so on until the power is eventually transferred to the wheels. I have some holes in understanding fully and would be helpful to understand the whole picture before understanding the individual parts and components.

    ReplyDelete
  23. Can you produce the video of V-12 engine ?
    Analyze the advantage and disadvantage of the V-12 engine.
    Since the WWII, V-12 engine had been used on Soviet Union T-34, German Tiger Tank
    P-51 Mustang, in the modern auto maker, Ferrari, Lamborghini, Rolls Royce also
    use V-12 engine.

  24. Could you do a video on limited slip differential.

    ReplyDelete
  25. - desmodromic valves look awesome. I myself understand how they work but I want to see you explain it to the masses. The guy who thought of them must be a genius.
    - DVVA (desmodromic FULLY variable valve actuation) is an even more complex system to attempt to explain to the masses.
    - LSD (someone already mentioned I see)
    - Revo knuckle MacPherson variant (ford focus rs exclusive I guess because I haven't personally seen it anywhere else but you may have)
    - natural dynamic balance (any flat/boxer, straight-6 and v12). Why BMW engine's run so smooth? :)

    I don't study these things at school, but I'm very interested in them and read and "saw" everything I could find on these subjects and more. But you do study and you also publish these videos which people watch so I would really like to see these explained. I know your list is so long it will take you "years" to go through so good luck and "godspeed".

  35. Awesome work there bud! Wish I had seen these videos while I was younger, maybe I would have chosen to go in for automotive engineering rather than finance. But the fact that you got a finance professional, with no prior knowledge of machines, addicted to your videos says a lot about your work. So thanks for that! Hey, would you know of a nice channel/ website where I could get to learn about hydraulic systems and esp. elevators incld. hydraulic & traction elevators? Thanks again & keep up the work!

    anyway, i'd like to see videos on clutch master/slave cylinders, fuel pumps and fuel injectors. water injection and methanol injection would be cool videos as well.
    keep up the good work!

    Have you ever consider making a video about suspensions using torsion bars? Until few years ago they were extremely popular among French cars at the rear suspension.

    ReplyDelete
  42. 10k's for ur video, they are wonderfully made & easy to understand 10k u again.
    Have u ever thought about making a video about CommonRail Turbo diesel engine & compare it to Fiat's MultiJet diesel engine??
    And one more thing: Am i right when saying that Fiat used for the 1st time CommonRail diesel engines & then they sold it(the patent) to Bosh who own's the patent rights today. So Fiat is using today MultiJet for their Diesel engines. Are they better, worst or just the same(as i think), but what's the difference of CommonRail & MultiJet?

  47. Hello Jason,

    First of all I salute you for the great effort you have put in these videos. Your language is simple and comprehensible no matter how complicate the topic is.

    So my suggestion for a video - The Fiat Multiair engines. I think it's a remarkable achievement from the Fiat group and it would be great to get to know about it's details, also it would great to know a little bit more about the Variator powered Alfa Romeo engines.

    Thank you in advance and keep it up!

  78. Hi,

    I've been trying to find out how the transmission is fit on a rear-engine/mid-engine and how it is operated (compared to a front engine + rear wheel drive).
    Could you please make a simplified sketch of it

    ReplyDelete
  79. Please Please Please do a video explaining how the wheelbase to track width ratio is relevant, while the outright measurement of either is inconclusive.

    I meet enthusiasts everywhere who seem to believe that because a 1st gen miata has a 90-something inch wheelbase it is short and snappy, when in reality, while light and therefore responsive, it drives predictably because it has a relatively long wheelbase compared to it's very narrow track width.

    ... And people think a Ferrari is stable because it has a "long" wheelbase when in reality it actually it can change directions much faster than a tuned miata partially because it's track width is wide and the ratio is more square... and it's stability comes from quality parts and engineering in the suspension.

    Would love to see this clarified mathematically for many enthusiasts!

    Thanks, Noah

    I drive a 2013 Toyota Aygo VVT-i.
    I would appriciate a video explaining Toyota's VVT-i.

    You already did a video on how weight affects acceleration. Because I drive a small and lean car, I then wondered how weight affects the cars consumtion. 90% of the time I am not alone in my car.

    Also I would like to get the purpose of (engine?)oil explained and how changing your oil type could effect your car/engine.

    I hope you'll do a video on above mentioned.

    Greetz from the Netherlands.

    PS. Watched more than half of your videos I think.

  89. Small engines vs Large engines.
    Does a small engine at double revs ie 1.0L at 4000rpm have the same power and efficiency as a larger engine at low revs ie 2.0L at 2000rpm?

  100. thank you sir for your videos , these are very good.I want to know about ALL WHEEL STEERING can you help me?Please

    ReplyDelete
  101. I think a good suggestion would be the purpose of a blow off valve, the difference between a recirculated and vented one and the benefits of each setup.

    ReplyDelete
  102. hey dude, love your work. I really think a video such as "what to look for when it comes to buying used cars" I feel your explanation's are vastly superior to others I've seen out there. For example, if you have access to quite a few cars, take a camera with you and record the engine, and try to identify faults, misuse, things that shouldn't be there or simply just a great looking engine.

    Cheers mate.

  103. I would like to hear about oil catch cans in the automotive aftermarket.

    2.also explain abot roll centre and centre of mass position& their effrct

    ReplyDelete
  106. Double clutching and power shifting would make a good lesson

    ReplyDelete
  107. Watched your videos and thought it was very informative. Suggestion I would have is to discuss the actual physics and calculations of a suspension. i.e. as a wheel hits a bump, what is actually happening with kinetic forces, potential energy, energy dissipation from the shocks on the compression and rebound etc. This might explain some of the shock dyno profiles on what it's trying to do. ie, prevent the wheels from getting launched off the bump, or having too much rebound so that the car crashes down after the bump. It would be nice to see some of the physical calculations of where all the forces are.

    Great stuff keep it up.

  112. 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..

  113. Hey, my DREAM car is the 1974 Chevrolet Corvette C3 Stingray. I would love to see a video explaining the 'big block' engine which drives that bad boy. What separates a big block from a typical engine? How does a big block differ in performance i.e. Horsepower and torque? things like that. Just wanted to say I worship your videos as my motorsports engineering messiahs and I think you've done a great job, keep it up! :)

    ReplyDelete
  114. I think from an engineering standpoint, one of the most fascinating race cars has to be the DeltaWing. I'd love to learn more about the concepts involved. If you look at the tiny front tyres you feel like you just can't begin to understand how they manage to pull more than 4gs through turns.

    ... and thank you for the great videos - I keep coming back even though it's in a foreign language to me.

  117. Thank you a lot for the videos. I've look on several videos and tried to figure why does a manual transmission car stalls. I have a good idea but I'm a bit confused because you change your manual transmission diagrams on some videos (obviously because of what you are trying to show). I would like to ask you for a video with the big picture including the gears so I can see the whole process. If you can't make it its fine, you've teach me more than enough..

  120. Hi, I saw your great videos on differentials, but I'm still wondering how the mechanics work which allow race cars (namely f1) to have have altering lock-ratios in different driving situations ( under braking, corner entry, corner exit, high sped corners , low speed corners).
    Also each of these settings can be changed on track, by the drivers on the steering wheel, but what happens under the hood if one of those buttons is turned.
    And what specific type of diffs are used today in f1 cars - maybe that should have been my first question- ?

  123. Hi Jason !
    I have gone through your transmission videos but i wanted to know more about split gears manual transmission like those in big trucks. Want to know the complete thing as to how flipping a switch makes the gearbox go to 10, 12 or 16 gears.
    Thanks for all the lectures even though i have to see many yet. They are really great !!!

  124. Can you talk about the relationship between horsepower and suspension? Specifically on Dodge Trucks. I hear a lot about how the suspensions are not well "tuned" to the amount of horsepower the engines have.

    Is the only drawback that there will be excessive forces on the frame or some components (bearings etc) on the truck while turning fast?

    ReplyDelete
  125. Thanks for the lessons! Would you like to discuss the difference between horizontally and vertically placed engines? And its relationship between where the engine is located front, middle, rear and the drive (front or rear, or 4wd/awd)? Thanks a lot.

  127. Hello
    I was wondering what does the brake calipers position differ from a car to another. and i believe its somehow related to the forces going on there. so what is it.
    i am getting my rotors changed so i would like to know what is it and what would happen if it was positioned in a wrong place and how would this affect me.
    the reason i am changing the rotors is a huge vibration as i brake while on 120+kmh speeds.
    thanks a lot man

  145. Hey there, I love your channel. Such great information. I'm just spitballing here, but here's what I was wondering:
    Have you ever considered branching out into other forms of Engineering? I completely love the cars information (especially since it's a form of engineering that I am not very knowledgable in), I was just curious. I think an electrical or sound engineering branch of this channel in the same type format would be awesome. Let me know what you think.

    ReplyDelete
  146. Any chance you could do a video on torque tubes? There seem to be a lot of misconceptions regarding them and not a lot of information available. My understanding is that a torque tube is used to transfer the reaction force from the tire/road torque to the body of the vehicle, but a lot of people seem to think that a torque tube transfers torque from the engine to the tires.

  161. I'm into rock crawling and have been trying to read of forums about setting up a good suspension. I learned that is is mostly considered vehicle dynamics. The forums seem mostly concerned with anti-squat and ways to combat it and the pros and cons of them. And how steep climbs are effected by it. As well as roll axis and how do go about finding all these. And what the link length and angle effect it. So, anything on this topic would be very helpful. As well as getting into the reason Ultra4 racers and other vehicles use both coilovers and triple bypass shocks. How triple bypass shocks work. And how to get the most out of them.

    I saw one request about rally cars, but you hadn`t answered to that (or i haven`t noticed that you have)
    I wanted to ask you the same. Rally is sort of my passion(the reason i like cars so much probably). And maybe you really could make video series about rally cars, their specifics and how cars have evolved (including B group, and continuing with WRC cars novadays).

  176. Hey man, great videos. Keep up the good work!

    Few things I/ve been wondering for a while.
    1. Different types of hybrids and how their heating and cooling systems work. There's no coolant flowing through engine to heat the vehicle the conventional way.

    2. Why do cars with a greater sloped rear window have a windshield wiper (Ex. SUVs, vans) and the ones with flatter rear window (sedans) not have wipers. You would think it should be the other way around if anything.

  177. Hey Man thank you very much for your videos, you're doing an awesome job.
    I have a question about engine stroke. If you had two engines with the same displacment but a very different way of going about getting that volume. For example you could have a 3.5L engine with a small diameter cylinder with a long stroke vs a 3.5L engine with a large diameter with a short stroke (I think lycoming airplane engines have that design) what would the dis/advantage be for both design concepts?
