In a 2-stroke engine, the entire combustion cycle is completed with just one piston stroke: a compression stroke followed by the explosion of the compressed fuel. Watch this quick video for a further description of how the 4-stroke engine works: These engines also do not require pre-mixing of fuel and oil, as they have a separate compartment for the oil. The spark plugs fire only once every other revolution, and power is produced every 4-strokes of the piston. In a 4-stroke engine, the piston completes 2-strokes during each revolution: one compression stroke and one exhaust stroke, each being followed by a return stroke. The Difference between a 2-stroke and a 4-stroke engine is how quickly this combustion cycle process occurs, based on the number of times the piston moves up and down during each cycle.
