The fuel injector is installed at the intake manifold injection before the inlet valve. It injects the fuel such that it builds a homogenous mixture with the added air. This air-fuel mixture is created by opening the inlet valve of the intake manifold into the combustion chamber where it is ignited by means of an ignition spark and burnt. A distinction is made between whether the injection is made prior to or during opening the inlet valves.
