Abstract
A fuel system for an internal combustion engine includes a small accumulator in which fuel is stored, a fuel injection nozzle including an electrically operated means which controls fuel flow through the nozzle from the accumulator, and a transducer for providing a signal representing the accumulator pressure. An electrically operated valve is provided to control the flow of fuel from a pump to the accumulator and the system includes a control circuit for the valve. The control circuit is supplied with the signal provided by the transducer and also with a desired pressure signal which conveniently is obtained from a pressure map to which a signal representative of an engine operating parameter is supplied.
