ABSTRACT:
A boost compensator controls the position of a fuel injection control rack in response to the induction air pressure and a centrifugal flyweight assembly increases the fuel injection volume when the engine speed is below a predetermined value. The boost compensator is provided with a releasing spring so that the control rack can be moved by the flyweight assembly independently of the boost compensator. An engine oil pressure sensor provides a maximum fuel injection volume for starting the engine when the oil pressure is zero and automatically decreases the fuel injection volume as the engine starts and the oil pressure rises to an operating value.
