@Ellotherem8 lol, I said lawn mower engine. If by luxury you mean price, the price would be very high for super car performance with a car powered by a lawn mower engine. And by my definition, the atom is definitely a super car.
sometimes when I do something that annoys the multiverse a Bart will open a portal to my room and give me a slap on the cheek and tell me that's a no no
Very informative video. Thanks! Here are my notes I've compiled, please correct me if I am wrong: Torque Converter: Only found in Automatic Transmissions. Not found in manual. Transfers power from the engine to the transmission. Consists of a lock-up clutch assembly, impeller (pump), stator (reactor), and turbine. Having the reactor in between the impeller (pump) and turbine makes it a torque converter. The impeller (pump), strator (reactor), and turbine all have fan blades, which have transmission fluid running through them spinning with Centrifugal force. The impeller (pump) moving in circles flows the transmission fluid through the strator (reactor) to the turbine to make it spin too. Without the strator (reactor), the impeller (pump) and turbine will not spin at optimal levels, but rather slow. The impeller (pump) helps the turbine spin as the transmission fluid flows. The stator (reactor) helps the transmission fluid flow from the turbine back to the imepller (pump) efficiently. The stator helps increase torque big time by making the transmission fluid shoot at an angle speeding the flow speed up, just like putting one's thumb over water flowing from a hose. This is viscous force. The stator has a one-way clutch, making the the torque converter only spin when the car is moving. To help the turbine spin faster, modern Torque Converters connect to a Lock-up Clutch, which is a shell-like component. The Lock-up Clutch sits over the turbine and connects to the impeller (pump). This allows for the turbine and pump to spin at the same speeds. The Lock-Up Clutch only kicks in after every gear has occurred, and is equivalent to driving at 5-speed in a manual vehicle. The torque converter connects between the motor and the transmission. The impeller (pump) sits near to the motor and the turbine splines to the front of the transmission onto the input shaft, which transfers power from the motor to the transmission. Rotation from the engine transfers to the transmission via the turbine sitting on a central shaft. A man made an amazing new design of the torque converter.
have a credit and debit, use your credit for small purchases like gas or food and immediatly pay it off in full using your debit. thats how ya do it bud :)
Gotta say, the fan demo was very simple, creative and easily explains how these work. I love how you guys make what seems to be really complicated stuff easy to understand. Best channel about automotive stuff on YT hands down. You deserve that 1mil subscribers.
I already knew how TC's work, but I watched anyways because you guys are great. Very clever (if a little flashy) to use two fans. Cool way to make the principle visible.
Wow, your production level is seriously incredible. Great job you guys. Darn kids have it so easy these days! I had to read all that from a paper ASE manual...
This over simplified explanation of the physics behind the mechanical power of vehicles has taught me so much. Thank you donut media for science garage
This reminds me of Bill nye except actually useful... And not cringy...and with good visuals... And you feel involved... And it's entertaining. Actually, this is nothing like Bill nye
I am by no way a licenced mechanic but I have gained a fair amount of automotive knowledge in the past two years I've been into cars. Never even realized why autos behave like a poorly shifted gear sometimes until today. This video has been mind blowing.
"I'll give you ZERO GUESSES" Hahaha I lost it! Great explanations for how these expertly crafted pieces of machinery operate. Can't wait for the next one.
Thank you so much I'm studying for my drivetrain A.S.E. and this video helped put a visual breakdown of torque converters in perfect perspective thanks 1,000,000!!!!
This is not technically correct in some places: 1:50 You've switched location of torque converter and a motor/generator - Motor-generator is coupled with engine. Torque converter allows engine to spin faster than wheels powering generator that can give extra power to motors mounted by the wheels. 2:44 Flex-plate. There is no need for extra flywheel when you have heavy torque converter bolted to it. 6:40 No! Turbine does not spin faster than impeller! Torque multiplication is happening when the impeller is spinning faster than the turbine. Actually it works best when the turbine is stopped (stalled). What is happening is impeller shoots fluid in one direction and turbine captures that fluid power by redirecting it in the opposite direction. Then the fluid leaving turbine travelling in that opposite direction hits the impeller which must redirect it again. They basically work against each other so the impeller is dragged by a turbine trying to slow it down and turbine is spun by the impeller throwing all that fast fluid to it. That is how the fluid coupling works. In a Torque Converter there is this stator that acts like a fixed ramp that captures fluid exiting turbine, bounces it back into correct direction and that redirected fluid is fed to the impeller that now has less work to do as the fluid is already going in a correct direction. Less work to do means that it can shoot that fluid with more force adding torque! This added torque from fluid being redirected wants to spin the stator backwards, but it is fixed (on a one way clutch) so it doesn't spin. But there is a catch: When the vehicle starts moving a turbine will start to spin. The fluid shooting out in the opposite direction is now shooting out of the moving turbine and it will be not going in the opposite direction that fast, thus it will rebound out of stator less. So the torque multiplication will be lower. Eventually it will spin so fast that the fluid will be going in same direction and a stator will become an obstacle. This is why they are mounted on a one way clutch, so that they will spin together with the fluid when the speed is high enough. 6:50 This has nothing to do with a viscous force. This has to do with a mass and speed of that fluid. 7:50 Lockup clutch is controlled externally by supplying pressuised oil to push on that clutch and is not affected by speed or torque transmitted by torque converter. You can even force it to remain locked all the time and stall the car because of that. 8:55 No, at this point torque converter did most of its job. The faster you go the less torque multiplication you get. (okay with that super long gearing and that "loose" converter you will still have some torque multiplication at this point, but less than on dead stop) The slip is what is really needed: It allows engine to speed up, build boost (more torque!) and spin the generator faster (more generated electricity that can be sent to the motors on wheel shafts) 9:03 thanks to the STATOR, not TURBINE! Without stator there would be zero torque multiplication, just the slip.
haah, that's something I did not know actually and i'm a smart person :) I always thought automatic clutch is same princible as manual, that it actually has 2 disks and it just slowly releases it and that brake pedal just acts like clutch and pushes clutch apart.
finally, somebody explains to me the thing I have always wanted to understand but never knew enough context. Cause like an electric motor is so simple, that's what I'm intimately familiar with being an eskate rider, combustion vehicles are so cool tho so many little things must be done to make them viable

You forgot he used the incorrect phrase centrifugal force. There is no such force
@@matthewyoung917 you nuts?
@@Ghosteriz he's actually not. Centrifugal force is used to describe two separate forces with normal and tangential directions
So uh.... automatics are driven by fluid? Lol
Yes, yes they are. As long as the lockup clutch remains unlocked all the power is being sent by fluid
haah, that's something I did not know actually and i'm a smart person :)
I always thought automatic clutch is same princible as manual, that it actually has 2 disks and it just slowly releases it and that brake pedal just acts like clutch and pushes clutch apart.
