ACTUATORS
Fuel injector
The fuel injector consists of a solenoid, piston, needle valve and a filter.
The injector is a small electromagnetic injection nozzle that injects fuel into the carburettor according to the signal
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).
TECHNICAL DATA: Winding resistance 12
Ω
Ignition coils
The ignition coils are of the top plug type (they are assembled directly on the spark plugs. This avoids the use of
the HT leads and enhance the overall system reliability.
