Turbocharger Boost Control
The electric wastegate control actuator operates based on a signal from ECM and adjusts the turbo charger boost control valve angle via link rod. The electronic control allows the turbocharger wastegate control valve to be opened even in non-supercharging regions. This reduces pumping losses and contributes to the fuel economy. In charging regions, wastegate valve angles are controlled by the electronic control with a high degree of accuracy.
