What does the number of engine strokes mean?
1 Answers
Engine stroke number refers to the movement of the piston from one end of the cylinder to the other. Characteristics of 2-stroke: Strokes are divided into 2-stroke and 4-stroke. A 2-stroke engine completes one working cycle with one rotation of the crankshaft, which includes intake (called scavenging in 2-stroke), compression, power, and exhaust. This is the characteristic of a 2-stroke engine. Characteristics of 4-stroke: A 4-stroke engine completes one working cycle with two rotations of the crankshaft, which includes intake, compression, power, and exhaust (known as intake stroke, compression stroke, power stroke, and exhaust stroke in middle school physics).
