'a 4 stroke engine cycle' is usually what it is called...
the four stroke engine cycle
In a two-stroke engine, two strokes is one cycle. In a four stroke engine, four strokes is one complete cycle. A stroke is a part of a cycle. Remember that the "up" motion and the "down" motion each count as one stroke.
It is called the compression stroke.
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
generally speaking if it has valves its a 4 stroke 4 cycle engine......if it doesnt have valves then it is a two stroke 2 cycle...................
The Ottoman Cycle
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
the cycle the engine moves
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
