Welcome to our comparison of two-stroke and four-stroke engines. An engine cycle is the sequence of events that produces power in an internal combustion engine. The main difference between these two types lies in the number of piston strokes required to complete one power cycle. A four-stroke engine completes its cycle in four strokes over two crankshaft rotations, while a two-stroke engine completes its cycle in just two strokes over one crankshaft rotation. Let's examine the four-stroke engine cycle in detail. The first stroke is the intake stroke, where the fuel and air mixture enters the cylinder through the intake valve. The second stroke is compression, where the mixture is compressed by the upward moving piston. The third stroke is the power stroke, where combustion occurs and pushes the piston down. Finally, the fourth stroke is exhaust, where burnt gases are expelled through the exhaust valve. This complete cycle takes four strokes and two full rotations of the crankshaft.
