Exhaust Emission Control SystemDescription and Operation Description Exhaust emissions (CO, HC, NOx) are controlled by a combination of engine modifications and the addition of special control components...
Circuit Diagram • COM signal - When controlling the voltage generated, the ECM sends the target voltage data to the alternator via a PWM signal.(High voltage: 4V or higher, low voltage: 2V or lower) • FR signal - The transistor activation signal inside the alternator monitors the voltage generated by the alternator to control the excitation current before it sends the FR signal to the ECM...
Desrcription The Electric WGT Control Actuator is installed on the turbocharger.It operates the vain in the Waste Gate Turbocharger (WGT) and regulates the compressed air amount by the ECM's PWM signal. This actuator consists of a DC motor which actuates the vane, a 2-step gear which increases torque of the DC motor, a position sensor which detects status of the vane, an electric control unit which drives the DC motor...
