INTAKE-COMPRESSION-COMBUSTION & EXHAUST IN DIRECT FUEL INJECTED GASOLINE ENGINE
Stoke 1) The inlet valves are opened by way of the camshaft to allow the air to enter the engine. At the same time, fuel is injected into the engine by way of the fuel injector. Note however that the fuel and air is mixed in the inlet manifold and not in the bores themselves. In the more simple injection systems, this process happens simultaneously, whilst in the more advanced systems, this happens sequentially
Stroke 2) During this stroke, the inlet valves are closed, the air and fuel mixture is further atomized and then compressed by the upward movement of the piston in the bore.
Stroke 3) At the top of this stroke (where the piston is in what is known as the top dead centre position) the the mixture is ignited by the spark plug, forcing the piston back down in the bore. Or side to side in the case of a boxer engine. The piston then pushes the connecting rod to turn the crankshaft. Stroke 4) On the final stroke, the exhaust valves are opened by another camshaft, the pistons comes back up the bore again, pushing the burnt gasses out through the ports. The time during which the inlet and exhaust valves are both open is known as the valve overlap.
