The correct order of the steps in the four-stroke engine cycle is intake, compression, power, and exhaust. This sequence is essential for understanding how a combustion engine operates.

During the intake stroke, the intake valve opens, and the engine draws in a mixture of air and fuel. This is followed by the compression stroke, where the piston moves up, compressing the air-fuel mixture, which prepares it for combustion.

The power stroke occurs next when the compressed mixture is ignited, causing an explosion that forces the piston down, generating power to turn the engine's crankshaft. Finally, in the exhaust stroke, the exhaust valve opens, allowing the burnt gases to exit the cylinder, making way for a new intake of air-fuel mixture in the next cycle.

This precise order is crucial for the efficiency and effectiveness of the engine's power generation. Understanding this sequence is fundamental for tasks related to engine mechanics and maintenance, and it reflects the basic principles behind internal combustion engines.
