A four-cycle engine, also known as a four-stroke engine, works through a process of four specific phases: intake, compression, combustion/power, and exhaust. These phases occur in a cycle that repeats itself, driving the movement of the vehicle. 1. Intake Stroke: The cycle begins with the intake stroke in which the piston moves down the engine cylinder while the intake valve opens. This creates a partial vacuum that sucks in a mixture of air and fuel. 2. Compression Stroke: The intake valve closes, and the piston moves back up the engine, compressing the air-fuel mixture. Near the top of this stroke, the spark plug fires creating a tiny, controlled explosion that forces the piston to move down, driving the power stroke. 3. Power/Combustion Stroke: The ignited fuel-air mixture burns rapidly, greatly increasing the pressure within the engine and causes the piston to descend down the cylinder. This translates to a force on the connecting rod connected to the crankshaft and therefore gener...
