What is the correct order of the four stages of a four-stroke internal combustion engine?

The correct order of the four stages of a four-stroke internal combustion engine is Intake, Compression, Power, and Exhaust.

During the Intake stage, the engine draws in a mixture of air and fuel, preparing for combustion. Next, the Compression stage occurs, where the piston moves up to compress the air-fuel mixture, raising its temperature and pressure in preparation for ignition. The Power stage follows, where the compressed mixture is ignited by a spark plug, causing an explosion that forces the piston down and generates power for the engine. Finally, the Exhaust stage involves expelling the burnt gases from the engine as the piston moves back up, clearing the chamber for the next cycle.

This sequence is vital for the operation of a four-stroke engine, as each stage plays a crucial role in converting the energy from the fuel into mechanical power. Understanding this order helps in grasping the fundamental principles of engine mechanics and operation.
