How does a 4-stroke engiene work?

Answer 1

A 4-stroke engine operates through four distinct phases: intake, compression, power, and exhaust. During the intake stroke, the engine draws in an air-fuel mixture as the piston moves down. The piston then compresses this mixture in the compression stroke, followed by ignition during the power stroke, where the burning mixture forces the piston down. Finally, in the exhaust stroke, the piston moves back up to expel the exhaust gases, completing the cycle.
