FUEL SUPPLY SYSTEM
Intake pressure sensor (13)
Location: in the intake manifold.
The pressure measured in the induction pipe is con-
verted into a voltage signal.
Moreover, the injection time also depends on the induc-
tion pipe pressure, especially when the throttle valve
opening angle is limited (during idling).
Throttle valve potentiometer (3)
Location: on the throttle body (14).
The throttle valve potentiometer measures the position
of said valves and acts as the main parameter in deter-
mining the injection time and ignition angle.
Coolant thermistor (15)
Location: on head "2" (16) (rear cylinder).
The temperature sensor detects the coolant tempera-
ture and is required to correct the injection time.
The injection time is increased if the coolant has not yet
reached the working temperature.
Atmospheric pressure sensor
Location: inside the engine control unit (5).
The intake pressure measured by the sensor is con-
verted into a voltage signal and is required by the en-
gine control unit to correct the injection time.
Air thermistor
Location: in the intake pipe of the left-hand air convey-
or.
The resistance measured by the thermistor is convert-
ed into a voltage signal and is required by the engine
control unit to correct the injection time.
