  1. TURBOCHARGER SYSTEM ILLUSTRATION


    • The ECM calculates an optimal turbo pressure in accordance with the driving conditions (engine speed, injection volume, atmospheric pressure and engine coolant temperature). It controls the variable nozzle so that the turbo pressure detected by the diesel turbo pressure sensor matches the calculated turbo pressure.

    • The turbo pressure (intake manifold pressure) is controlled by the variable nozzle vanes located in the turbine area. This nozzle is actuated by the actuator that is directly connected to it. This actuator is actuated by the vacuum pressure that is regulated by the vacuum regulating valve in accordance with signals from the ECM.

    • The turbocharger has a nozzle vane which opens and closes to control the volume of the exhaust gas flowing to the turbine. This, in turn, controls the boost pressure. When the nozzle vane moves in the closing direction, the pressure increases. When the vane moves in the opening direction, the pressure decreases.
