Torque is determined by the amount of angle on the crank. Whether that is done by rod length or stroke length, is up to the designer. Rod to stroke ratio is what it's called and the lower the ratio, generally the more torque you will have. That however means the components have more load on them for a given RPM. That's why you see F1 cars have a rod-stroke ratio of 2.2 and a really short stroke. They make no torque down low because of it, but they rev to 14k RPM, which do to the bore size is where they make most of their power.
Also displacement is a function of bore and stroke, so technically, stroke is related to the argument of creating torque.

Cosworth DFV had a r/s ratio of about 4:1

Google suggests I might be wrong.
I remember reading it as 4:1 in the handbook though.

KEK!

Well I'm sure it depends on the application. Of the high revving F1 engines, I'm sure the new ones have lower ratios because of improved materials and manufacturing techniques that allow the parts to take higher loads from increased torque at those revs.
>>14758763
I think it's more to do with making the engine as small as possible for better aero.
F1 engines would be very different if aero wasn't such a dominant factor
>>14758776
Yeah good point. I hadn't really thought about that.
>tfw they should switch to pushrods..
Either that or use something like an intermediate shaft to make the cam gears smaller on a DOHC motor.
>>14758787
actually some of the engines back in the days of the DFV were looking into pushrods again, two cams in the valley operating only the intake valves.
didn't come to anything obv
>>14758804
Wow that's weird. Do the exhaust cams stay on top?
>>14758821
yarp
>>14758856
neat
>>14758693
The reason F1 car make no torque down low is because the cams, heads and pretty much everything else is optimised for top end power.
Short strokes and long rods are mostly used to reduce stress on the rotating assembly
