The kinetic energy is produced by the violent expansion of gases in a confined area.
In a 4-stroke V8 you have 8 bangs for ever 4 revolutions. If you double the RPM you double the number of bangs and thus the generated kinetic energy. There are of course losses involved in increasing RPM so it is a case of diminishing returns.
No. I was right the first time.
The piston and crank does not produce any power. They only convert the kinetic energy produced by the expanding gases into rotational force, know as torque.
Just when you think it cant get much better.
I said "violent expansions", not explosions. Reading comprehension again CAP...My car is moved by the violent expansion (read it right this time) of gases in a confined space. That's where the energy is produced. Nowhere else.
