  • Engine de-compression mechanism
    Patent number: 4061123
    Abstract: An engine de-compression mechanism in which the valves to one or more of the cylinders are locked in open position to prevent fuel from being drawn into the engine cylinder during the normal intake stroke and to prevent compression back pressure on the piston during the compression stroke. The function of the de-compression mechanism is to put one or more of the cylinders of the engine out of operation to conserve fuel when driving at high speeds.
