Torque is rotational kinetic energy.
The chemical energy stored in the fuel is converted into kinetic energy by heat expanding the gas. The cylinder and piston converts this kinetic energy into linear kinetic energy, which is then converted into rotational kinetic energy by the crank. At the end of the power train the wheels convert the rotational kinetic energy into linear kinetic energy in the form of propelling the vehicle forward.
Please... please... get it.

The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Negative work of the same magnitude would be required to return the body to a state of rest from that velocity.
http://en.wikipedia.org/wiki/Kinetic_energytorque moves the car. kinetic energy is stored in the car as it cruises.
but now that we've established that torque moves your car, do you get it?
the torque curve can be optimized to be where ever the engine designer wants it.
lower is often better, although you guys that like the little 4 cylinders seem to think it's better to rev an engine till it's bordering on exploding.
oo......the word i forgot in the other post was "obtuse". a customer walked in, and i had to tab over to my invoicing program.
oo....BTW...the combustion process does not create kinetic energy.
