How many strokes are in a cycle with a 4-cycle engine?

A 4-cycle engine, also known as a 4-stroke engine, completes a cycle of operation through four distinct strokes: intake, compression, power, and exhaust. Each stroke corresponds to a specific phase within the engine's cycle.

1. During the intake stroke, the engine draws in the air-fuel mixture.

2. Next, the compression stroke occurs, where the mixture is compressed within the cylinder.

3. The power stroke follows, which is when the compressed mixture is ignited, producing power that drives the piston down.

4. Finally, the exhaust stroke takes place, expelling the burnt gases from the cylinder.

These four strokes are essential for the engine to function properly and efficiently. The operation of each stroke helps contribute to the overall power output of the engine, and together they complete one full cycle of operation. This distinct cycle is why the answer indicating there are four strokes in a cycle with a 4-cycle engine is accurate.

The other provided options do not align with the defined operations of a 4-stroke engine, as they suggest fewer or more strokes than are actually involved in the complete cycle.
