The compression stroke during the working cycle of a 4-stroke engine. |
A 4-stroke engine burns a mixture of air and petrol to drive a piston and rotate a crankshaft. Unlike a 2-stroke engine, there are separate induction, compression, combustion and exhaust strokes. Therefore, a 4-stroke engine fires on every other revolution of the crankshaft. The screen shot on the left is from an interactive animation that clearly demonstrates all the stages of the working cycle. Controls enable the instructor or student to play, pause, loop, step forward or step backward a frame, zoom in or out and even print.
