ABSTRACT:
An engine valve timing control system using electrohydraulic valve lifters or adjusters operatively connected to a microprocessor based electronic control unit will provide real time charges in engine valve timing. As a result, engine performance will be improved over the mechanically controlled engine valves which at best are compromises between engine operating extremes. Each lifter is "homed" to the base circle of the cam through the use of check valves and high pressure pulses generated in the oil lines supplying the lifters.
