Abstract
In a fuel system for delivering pressurized fuel both to an internal combustion engine and to an exhaust installation, the fuel system includes two separate branches for delivering fuel to the internal combustion engine and to the exhaust installation, and includes a primary fuel pump delivering fuel to both branches of the fuel supply circuit. The primary fuel pump output is controllable independently of the engine speed. The pump output may be controlled such that the pressure of fuel in the fuel supply circuit depends on whether fuel is to be delivered to the exhaust installation. The fuel system may include a hydraulically controlled shut-off valve arrangement which is forced to switch depending on the pressure in the fuel supply circuit.
