What are the four strokes that occur in each cylinder of a typical four-stroke engine?

• A. Intake, Compression, Power, Exhaust
• B. Intake, Combustion, Power, Venting
• C. Intake, Compression, Ignition, Exhaust
• D. Compression, Power, Venting, Exhaust

Answer: (A)

In a typical four-stroke engine, the four strokes that occur in each cylinder are intake, compression, power, and exhaust. During the intake stroke, the intake valve opens, allowing the air-fuel mixture to enter the cylinder. This is followed by the compression stroke, where the piston moves up and compresses this mixture to increase the efficiency of combustion. After compression, the mixture is ignited, resulting in a power stroke where the explosion pushes the piston down, producing mechanical power. Finally, in the exhaust stroke, the exhaust valve opens, and the piston moves back up, pushing out the burnt gases from the cylinder. This sequence is essential for the operation of the engine, ensuring that each cycle is completed effectively to generate continuous power. The other options contain terms that do not accurately represent the cycles of a four-stroke engine or misuse terms relating to the phases of operation.
