Digital system power / control (engine 1Z)

Digital control system engine with direct fuel injection, among other elements, provided for the diesel engine comprises a control unit, a number of sensors and actuators (see. Below). Moment and duration of injection are determined by the control unit, depending on the frequency of engine speed, position and velocity of the throttle opening, the specific volume of the air temperature, coolant temperature and fuel, the atmospheric pressure (altitude) and the vacuum in the intake manifold. Information about these options comes from the sensors installed on the engine.

The system uses a two-stage injector that improve the combustion characteristics, providing reduced noise and improved composition of the exhaust gases. A third cylinder injector needle lift sensor.

In addition to the power supply system, the computer controls the operation of recycling systems and reducing emissions, control circuits boost pressure of the turbocharger and launchers candles.

Fault and installation of the initial moment of injection of the engine management system is only possible with a special diagnostic equipment - if necessary, refer to the profile service station.
