Dear Fyo:

That is not entirely true. There are two things in a modern engine that run at a different speed, the first is the camshaft and it runs at half the speed. The second is the distributor and it also runs at half speed. The water pump runs at a different speed as does the alternator. A turbo or supercharger also runs at a different speed and the former has no constant relation to the crankshaft speed. My old RX4 wankel engine also had two speeds, the rotors rotated at 1/3 the speed of the crankshaft. In a radial aircraft engine, the crankshaft does not rotate at all.

Without the camshaft, no piston engine would run.

Pete
