Aug 14, 2025 · Learn all about how four-stroke engines work, their main components, and why they matter in modern vehicles. Learn how a four-stroke diesel engine works on the principle of the diesel cycle and completes a single cycle in four strokes of the piston. Exhaust stroke. During the exhaust stroke, the exhaust valve is open and the intake valve is closed. The engine crankshaft keeps rotating by inertia from the previous power stroke. In the power stroke, the pressure of hot gases created during the combustion pushes the piston down with great force. Compression Stroke. As the piston moves up, it compresses the air trapped in the cylinder. Compression stroke. The piston moves up pushing the remaining exhaust gases out of the cylinder and into the exhaust manifold. A typical four-stroke engine diagram shows key components such as the piston, cylinder, crankshaft, connecting rod, valves (intake and exhaust), spark plug (in petrol engines), and fuel injector (in diesel engines).
