Task The fuel is injected so that it forms a homoge-neous mixture with the air; this mixture is fed into the area of the combustion chamber most favorable for combustion. The aim is to prevent excessive fuel condensation on the wall of the intake manifold or intake valve.
Function The fuel injector is installed in the intake manifold in front of the intake valve, where its solenoid valve con-trols injection start and duration. Several ultra-precisely manufac-tured orifices ensure fine fuel atomization. The shape of the fuel spray is determined for each engine by the position of the injector as well as the configuration and number of orifices. For small en-gines in particular, the reduced size allows for more flexible mounting. A low-noise injector is relevant for operators of two- wheelers, as they are more exposed to noise from the vehicle and from the environment.
