Q » How does a four-stroke engine cycle work (intake, compression, power, exhaust)?
17 Oct, 2025
A » A four-stroke engine operates through four distinct phases. During the intake stroke, the piston descends, drawing in air-fuel mixture. The compression stroke follows, as the piston ascends, compressing the mixture. The power stroke occurs when the spark plug ignites the mixture, forcing the piston down. Finally, the exhaust stroke expels burnt gases as the piston rises again, completing the cycle and readying the engine for the next operation.
