Adding more stroke to your combo makes more low end HP.

There is more to saying that a longer stroke makes more torque...

the stroke increase is typically very small (for example, say going from 3.622" to 4.000", this is only a 0.189" increase in crank arm radius)... this produces only a small increase in torque due to the crank arm moment... but it does increase piston instantaneous velocity a lot, and this has other effects (increase in rate of compression, increase in dynamic friction, other), and these in turn have other effects (rate of cylinder fill, spark knock threshold, power consumed by increased friction, other)...

there is a lot more to simply saying that longer stroke makes more torque.

Hmm,

I think I see what is happening.

You don't understand, or you are pretending not to understand.

In the first case, let me explain:
A1: The wrong question is being asked. Because clearly, we can define torque mathematically, and are no closer to understanding what we are asking.

This is why in my answer, I only defined torque: I am proving that the question is incorrect, since correct answer gets a big red stamp on it with an X through it by the computer.


In the other case, ur just being a jerk. I don't think this is the case, not this time anyways.
So tell me where you are are stuck now and I will finish it off for you in friendly manner.

Why did you feel the need to bump a thread that was started almost 4 years ago to say the question was incorrect?

I get the feeling like, this needs to be worked on. Where is the big picture of a non-opaque car showing engine torque as being applied by the piston to the wrist-pin and then to the crankshaft of length L, being multiplied through the transmission gears, then again through the differential, and finally applied via axle at some radius from the outside of a tire to the Earth with some frictional coefficient f, with some frequency, rate of change of angular velocity etc.. to get work in kjoules/second (kwatts), horsepower, all the good units.

I bet it would make a great poster. Suddenly I want this on my wall in a 25x40 or some large size so I can inspect it up close.

Another tedious one-sided dialogue of total irrelevance......

Here's a bunch of stuff most of us already know mixed in with a bunch of nonsensical rambling

You sure do like to type a lot to say very little.

The entire premise of "make more torque" could in itself be a flawed question... makes more low end torque if everything else remains the same, yes.

I think the solution is to stroke 4 cylinders and destroke 4 cylinders. That way you have both low end torque and high rpm hp.

Maybe the added stroke will make up for all the torque lost by the rectangle ports

G Atsma

Round ports, SURE! THAT'LL make those square wheels RUN!

Its just a poster. Dont get excited or overreact.
