  • Control device for an air valve of an engine
    Patent number: 6877469
    Abstract: The present invention provides a mechanism for controlling the intake valve of an internal combustion engine, which mechanism is capable of consuming less energy, i.e. less oil. Through uniquely designed cam and rocker as well as joining mechanism joining the rocker and the stopper, this mechanism does not incur the spring resistance as opening the intake valve, thus the engine per se does not additionally consume energy, so that the object of reducing oil cost and promoting power output may be achieved.
