INPUT/OUTPUT SIGNAL CHART

*: This signal is sent to the ECM via the 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.
