The fuel injector injects the fuel in such a way that it forms a homogeneous mixture with the air; this mixture is then fed into the area of the combustion chamber most favorable for combustion. The aim is to prevent excessive fuel condensation on the wall from the intake manifold or intake valve.
The fuel injector is installed in the intake manifold in front of the intake valve. It is a solenoid valve that is used to control the injection start and duration. Several ultra-precisely manufactured orifices ensure fine fuel atomization. The shape of the fuel spray is determined for each engine by the position of the injector and the configuration and number of orifices.
For small engines in particular, a smaller injector enables more flexible installation. A quiet injector is also important for riders on two-wheelers, as their exposure to noise from the vehicle and the environment is greater.
Bosch fuel injectors have proven themselves a million times over. They have all the technology necessary to optimize spray preparation and configuration – for any engine.
