2 full revolutions of the crankshaft equals one complete cycle on a standard 4 stroke internal combustion engine.
The crankshaft makes two complete revolutions to complete one thermodynamic cycle. The crankshaft rotates 180 degrees during each stroke of the engine. Hence a total of two revolutions occur after completion of the four strokes. Chechout "www.howstuffworks.com " to see how crankshaft works.
The crankshaft does 2 full turns to make 1 cycle in a 4 cycle engine so, 4 is the answer.
2 revolutions
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.
Two complete revolutions, therefore 720 degrees.
6000 revolutions is concidered the beguining of hi stress of a 4 cycle combustion engine. you can see how fast your belt is spining looking at the tachometer wich most cars have. It tells you how many revolutions that engine is per minute. Anything from 500 - 800 revolutions is concidered the slowest speed wich an engine needs to stay on.
The firing order will differ between the engine brands. The four stroke engines do need two revolutions instead of one to complete a cycle, and the firing order usually starts at one. Check for your exact engine for more specific details.
