a two stroke cycle said that two stroke of the piston to complete firing 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.
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
Yes. A 2 cycle engine is also called a 2 stroke engine.
Four-stroke lawn mowers have a tube where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
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...................
Two stroke. oil injected.
Yes, most chainsaws do have two stroke/cycle engines. However, people have made them with four stroke/cycle engines such as the V-8 chainsaw seen here: http://www.youtube.com/watch?v=60Tamp2fHhg

one rotation
I think you are looking for a detailed engineering answer. Common usage is that a two stroke engines is called a two stroke engine. By the way my experience says that two stroke engines only have two strokes and the second one is fatal.
