  • Fuel supply control system for an engine
    Patent number: 4771746
    Abstract: A fuel supply control system for an engine has an engine speed sensor for producing an engine speed signal, a sensor for sensing amount of lubricating oil in an oil pan of the engine and for producing an oil signal dependent on the amount of the oil. In response to the engine speed signal and oil signal, fuel supply is cut off when the engine speed exceeds a predetermined engine speed above which bouncing of intake and exhaust valves of the engine occurs.

  • Intake air control system for an internal combustion engine
    Patent number: 4724818
    Abstract: A bypass is provided around a throttle valve of an engine, and a solenoid operated on-off control valve provided in the bypass so as to control flow of intake air. When the engine is accelerated in the coasting of a vehicle, an acceleration signal is produced. In response to the acceleration signal, a driving pulse train is fed to the control valve so as to reduce the intake air flow in dependence on coolant temperature of the engine by the coolant temperature.
