ABSTRACT:
A vehicle speed limiting system for a vehicle having an engine which includes a plurality of fuel injectors coupled to an inline, low volume fuel injection pump operative to successively trigger a flow of fuel directly to the individual fuel injectors. The vehicle speed is converted to a speed signal which, when it reaches a preset limit, is utilized by the system control to close a fuel control valve through which fuel normally passes to the injection pump, and also to simultaneously open a pressure regulator. The fuel control valve includes a small orifice to pass just enough fuel to prevent pump cavitation. The system is characterized by a low fuel residual upon cutoff by the fuel control valve so that the engine speed is quickly slowed for lack of fuel.
