System Description

INFOID:0000000000956508

INPUT/OUTPUT SIGNAL CHART

*: This signal is sent to the ECM through CAN Communication line 

SYSTEM DESCRIPTION

This mechanism magnetically controls cam phases continuously with the fixed operating angle of the exhaust
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine oil tem-
perature. Then, the ECM sends ON/OFF pulse duty signals to the exhaust valve timing control magnet
retarder depending on driving status. This makes it possible to control the shut/open timing of the exhaust
valve to increase engine torque and output in a range of high engine speed.
