ABSTRACT:
This invention relates to hydraulic control of intake valves and fuel injection of spark ignited internal combustion engines to effect a sonic-type induction system. The invention is an extension of a previous application by the same inventor, which provides a hydraulic actuation system for a prescribed valve opening of all the engine valves. The new system, in substance, provides a means to divert, in varying amounts, actuation fluid as supplied by the former system so as to impart a variable lift to the intake valves and, proportionally, to the fuel injection metering valve(s). The result is an induction system capable of maintaining an accurate air-to-fuel mass ratio.
