  • Controlling internal combustion engines
    Patent number: 4092970
    Abstract: A device for controlling maximum speed and/or acceleration of a diesel engine by means of a spring-loaded valve located upstream on the air inlet manifold. The valve, which normally is open, operates on a pressure differential basis and is designed to close when maximum speed is exceeded. By sending the air flow rate to the engine, the air flow can be shut off when it exceeds a rate corresponding to an excessive engine speed.
