What creates engine rpm? This is what I read. The rest pertains to internal combustion, except the starter response. But does an electric motor have rpm, how about a steam turbine, wind mill? Even what increases or slows down rpm is not just combustion, but force against a shaft to cause or slow rotation. RPM is still just a measurement, kinda like time not a physical thing. Guess what kids, time travel is not possible. How ever when I get behind the wheel..... Hmmmmmmmm.
