Air intake injection system
ACTUATORS
The fuel injector consists of a solenoid, piston, needle valve and a filter.
Fuel injector
The injector is a small electromagnetic injection nozzle that injects fuel into the carburettor according to the sig-
nal coming from the ECU.
When the solenoid is agitated by the ECU, it becomes an electromagnet and attracts the piston. At the same time,
the needle valve incorporated in the piston opens and the injector, under pressure of the fuel, injects the fuel in a
conical dispersion. Given that the opening of the needle valve is constant, the volume of fuel injected at any one
time is dependent on the time that the solenoid is agitated (injection time).
