SYSTEM DESCRIPTION

This mechanism hydraulically controls cam phases continuously with the fixed


This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intakevalve.

The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolanttemperature.

Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing (IVT) control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.
