ABSTRACT:
A common-rail fuel injection system for an engine includes a common rail for storing fuel. A plurality of pumps supply fuel to the common rail. Fuel is injected into the engine from the common rail. Feedback control is executed on the pressure of the fuel in the common rail. A device serves to detect whether or not at least one of the pumps fails. An arrangement decreases the pressure of the fuel in the common rail when the detecting device detects that at least one of the pumps fails.
