Control unit EMS 2
The control unit checks and controls the unit injectors
so that the correct amount of fuel is injected into each
cylinder. It calculates and sets the injection angle.
The control is primarily performed using the speed
sensors and the combined sensor for boost pressure/
boost temperature.
The EMS 2 system processor is located in the control
it is protected from moisture and vibration.
The processor receives information continuously
engine speed
camshaft position
boost pressure
boost temperature
coolant temperature
oil pressure
oil temperature
oil level
crankcase pressure
piston cooling pressure
water in fuel
fuel pressure
coolant level
air filter pressure
air filter temperature
Information from the sensors provides exact informa-
tion about current operation conditions and allows the
processor to calculate the correct fuel volume, check
engine status etc.
