MIVEC (Mitsubishi Innovative Valve Timing Electronic Control System)




System Configuration Diagram



  • The engine-ECU assesses the driving conditions of the engine by way of the signals input by sensors.
  • Based on the assessed information, the engine-ECU outputs duty cycle signals to the inlet oil feeder control valve in order to control the position of the spool valve.
  • By varying the position of the spool valve, the oil pressure can be applied either to the retard or advance chamber, thus continuously changing the phases of the inlet camshaft.
