The tachometer is an electrical device that senses the ignition system. It indicates engine RPM (revolutions per minute). Engine rpm and crankshaft rpm are two ways of expressing the same thing. True, the crankshaft does rotate twice for each complete set of cylinder firings but the tachometer counts each rotation.
crankshaft The crankshaft rotates. A torsion bar twists.

The engine's camshaft rotates at half the speed of the crankshaft. The crankshaft turns two full turns for every one full turn of the camshaft.
There is a crankshaft position sensor that measures how fast it rotates
One half the speed of the crankshaft.
i am doing a coures in tafe inspect and service engines and i would like to know this rotates the crankshaft as the piston moves down the cylinder
one half the speed of the crankshaft.
An automotive engine's camshaft rotates at A. the same speed as the crankshaft. B. one-quarter the speed of the crankshaft. C. one-half the speed of the crankshaft. D. twice the speed of the crankshaft.
Technically both, before the vehicle is running on its own via combustion the crankshaft rotates and moves the pistons, once combustion has occurred the pistons take over if you will and turn the crank which rotates the next piston into position for combustion
It's a bearing that the crankshaft of an internal combustion engine rotates on.
The main bearings and main bearing caps.
A crankshaft is the part of the engine that the linear piston rotates. The amount of turns in a crankshaft to complete 1 revolution in a V6 engine is four.
