What is the working process of a four-stroke gasoline engine?
1 Answers
The working principle of a four-stroke gasoline engine consists of four strokes: intake, compression, power, and exhaust, completing one working cycle. During this process, the piston moves up and down four times between the top and bottom dead centers, and the crankshaft rotates twice accordingly. Below is a detailed introduction to the working principle of a four-stroke gasoline engine: 1. Intake stroke: The piston moves down, drawing in the air-fuel mixture. 2. Compression stroke: The piston moves up, compressing the air-fuel mixture. 3. Power stroke: The fuel is ignited, and the piston is forced down to do work. 4. Exhaust stroke: The piston moves up, expelling the exhaust gases.
