    In this video I cover the purpose and operation of the turbine, stator, impeller, and torque converter clutch. I hope the explanation and practical give you some insight into how these parts work to not only transfer power from the engine to the transmission, but also how it drives the transmission pump and doubles the torque output of the engine when you take off from a dead stop. I've wanted to make this video for some time. In fact I've had the fans sitting in the back of the shop for almost a year. Now that I have the Automatic Transmission Dissection video under my belt I thought I would add a torque converter dissection into the mix. I hope you enjoy this video and that it gets you a better understanding of torque converter operation. Especially since I killed my air compressor cutting this one in half.

But I wanted to know how it worked so I searched for video. My first hit was the LearnEngineering one. Less than half the length and really easy to understand what all 4 components including the lock up clutch did. Immeasurably better.

    My 1993 Oldsmobile started stalling at stoplights all of sudden. Thought I had a big problem. Finally got the car home after pissing off a whole lot of drivers behind me. Turned out to be the converter lockout solenoid. Part was $20, solenoid was under the transmission cover on the driver's side. Was a fairly simple repair and car was back to normal. A very small part that caused a big headache on the road. Excellent video by the way.

  • @jackt6112
    @jackt6112 2 роки тому +43

    That was well done. I started out in automotive engineering. When starting out, there is a big difference in the rpm between the impeller and turbine. The impeller is then acting like a centrifugal pump accelerating the fluid to the outside and at an angle against an opposing angle on the turbine blades which are not spinning, making them a bit like a bucket on water wheel to extract some of the kinetic energy after which it is routed to the stopped or lower velocity inner diameter of the turbine, and back toward the inner diameter of the impeller where it will be sucked in and accelerated again. However, with the large difference in velocity and the opposite angle, the remaining kinetic energy opposes the impeller so there can be no torque gain unless you redirect and reuse that energy with a stator to assist the impeller. The stator attempts to rotate backwards and it cannot because the sprag/roller/one-way clutch doesn't allow it to, and it redirects the fast-moving fluid into the direction of the impeller at to further accelerate the fluid, which is where you get torque multiplication, ~2:1. However, as the turbine rpm gains equilibrium with the impeller, the turbine now produces its own back pressure from centrifugal force, thereby mostly balancing this out. However, with the angle of the inner turbine blades plus the rotation of the turbine being almost as fast as the impeller, the stator will now rotate with the impeller and turbine to give the best flow. This point is called couple or lockup, although it is not really coupled or locked up, but it will be less than 10%, slower depending on the converter, and torque multiplication will be 1:1. Thus, max torque multiplication occurs when the impeller is turning and the turbine is stopped. If something is wrong with the stator and it rotates in both direction, acceleration will be poor. If it won't move in either direction, it will add a load on the engine during coupling and cause heat buildup. Then came lockup torque converters where they actually do lock the impeller and turbine together physically, so they tend to refer to the former as couple rather lockup. The difference between a torque converter and a fluid coupling is the stator, which enables the multiplication of torque. So are fluid couplings obsolete? No. They are used in a lot of applications to isolate vibration between driving and driven members, and even gentle startups when an engine is running at a fixed RPM like electric engines and fluid is slowly added such as to start a conveyor belt with tons of product on it.
    The stall speed is the maximum rpm that the engine can turn when using all of its power against a stopped turbine. Logically, that depends on how much torque the engine has. While true, with something relatively heavy such as transmission fluid, small changes in RPM make big changes in torque to make a small rpm change, so it won't vary by as much as you think, which is why they can categorize them by stall speed. You can also see that the smaller the diameter, the faster you will have to spin it to equal the same outside velocity to achieve the same centrifugal force and pumping action on the fluid plus they have less area on the blades so a 1" difference in diameter can make a substantial difference in stall rpm. The stall rpm will vary more with torque variations as well, but still not by a lot. Of course the First Law of Thermodynamics states that neither matter nor energy can be created or destroyed. When the engine creates all of that high velocity fluid against a stationary turbine, the energy has to be dissipated somewhere, and it is. The engine horsepower is converted to heat, which is why the transmission cooler in the radiator, unless you have a wimpy engine in which fins on the outside of the converter and air holes in the bellhousing can do the job. Larger diameter converters are more efficient even during coupling. However, when overdrive transmissions and higher gear ratios became more and more popular, engine rpm dropped near or below where coupling would occur even at speed, so there were efficiency losses with more power going up in heat in the converter. This made the move to lockup converters compelling.
    From automotive engineering to aviation mechanic to military pilot, the engines made perfect sense to me right away because they use a stator to similar effect as torque converter except jet engines don't allow the stators rotate with the rotors because it is always pumping, unlike a torque converter, thus unnecessary. Another difference is the stators are where the compression is occurring when it converts the kinetic energy into static pressure, and redirects the flow direction into the rotor blades of the next stage. Torque converters don't compress the fluid but rather add to the kinetic energy to be expended against the turbine by feeding accelerated fluid back into the impeller to be further accelerated.

When draining the trans fluid, it was blacker than black. Also changed out the trans filter and gasket and cleaned trans pan and magnets. And added a bottle of Lucus trans fix. Doing this much needed maintenance (previous owner failed this important maintenance) greatly improved the transmission performance. And engine code for the torque converter has not returned in the 5 days of driving my kids to and from school. So tyvm Eric for making this video and doing an awesome job of explaining the toque converter 👍👍

However I think there are a goodly number of ways in which his language could be improved. A good number of places where where his language is ambiguous. He tries to make things understandable by repeating himself, using a slightly different sentence structure, but the repeated sentence, or phrase, is not any clearer than the original.

    Wonderful explanation. I've long understood abstractly about the need for a stator, but here I got to see one and what it's connected to. Good work Eric. Thanks.

    Brilliant explanation with the two fans!
    This is exactly how a turbine shaft engine works on helicopters. The Compressor section and turbine section are only connected by hot air. The expanding gases force the power turbine section to turn and power is transferred to the main transmission.

    • @uwekonnigsstaddt524
      @uwekonnigsstaddt524 5 років тому +1

      The world of turbines. They need a FLUID (Air and liquid are both defined as FLUIDS, one is less denser than the other) in order to TRANSFER the mechanical force needed to extract its energy into function. In a fan jet (not a turbo shaft) engine the rapid expansion of the combustion gases are “routed” into the turbine section, that turbine turns (torque) just as the fans do in the video. That turbine, as it rotates, causes a shaft to turn, and that turning energy then is transferred (thru a driveshaft) to the main fan up front of the engine (compressor) that would then move air to the rear, compressing it in the process. How that energy is EXTRACTED for utilization in the engine makes the difference in what TYPE of turbine engine it is. There’s another video, a lot shorter, that uses video animation to explain how torque converter works. It took me a few replays of the video to get MOST of the hang of it. But this video (longer) explains it a lot better, specially with the use of air fans. Well made!!!

    A super great video. 10 days ago, I had to add transmission shudder fix because at shifting lower gears, I had hesitation till I built up to top speed and gear. Now I better understand why the shudder fix worked for me. Thanks for the great video.

    • @kenforu1531
      @kenforu1531 Рік тому

      Your shudder was due to lock up clutch. If you keep the car it'll eventually need a converter.

    FIrst, I loved the " practical" with the fans -- it really demonstrates the concept. Second, some automatics designed for hauling heavier loads will use the lockup clutch in more than only the highest gear in order to limit heating of the transmission fluid.

    I went from knowing the term “torque converter” and that it had something to do with an automatic transmission to having a general understanding of it in 15 minutes.
    That is some impressive educational compression, sir!
    The only down side is that now I feel the need to learn how the rest of the automatic transmission works. It will be time well spent.
    New to the channel, but if you need extra areas to explain, all of the suspension bits (ball joints & tie rods & whatever else goes between the body and wheels) would be a great series. Also a shock absorber versus a strut. There were a few decades where I had the luxury of not repairing my own cars, and I missed a lot along the way!

I never had anyone explain in such a way, simplistic and with fans, great video. amazing what goes into a torque converter. last few statements were a plus.i will be looking over all your videos now. love learning and miss my car days from off road racing to IMSA to NHRA You gave me a rush to go get a race car and build understand and race again ;') Thanks for rejuvinating a man that just turned 60.
