    what's the main difference b/w four stroke & two stroke engine?
    The main difference is that in 4-stroke engines, there is one power stroke in 2 revolutions of crankshaft whereas in 2-stroke engines there is one power stroke in every revolution of crankshaft.

    4-stroke engine comprises of following four strokes: Suction--Compression--Expansion(or Power)--Exhaust.
    2-stroke engine comprises of only Compression and Expansion stroke as Suction and Exhaust occurs simultaneously with piston movement.
