ABSTRACT:
A system for supplying motor vehicle diesel engines with fuel, having a fuel circulation system with a fuel supply pipe leading from a fuel tank, via at least one fuel filter, to an injection pump driven by the diesel engine; a fuel return pipe leading back to the fuel tank; a fuel-circulating pump that can be driven electrically and is not dependent on the operation of the diesel engine; and a heat exchanger for causing heat exchange between the fuel flowing through the fuel supply pipe and a liquid heat-transfer medium. Also, when the diesel engine is stopped, the fuel-circulating pump can be driven from an on-board power source. The fuel circulation system is arranged in such a way that, when the fuel-circulating pump is in operation, it is flushed by circulated fuel throughout its full length. An auxiliary heater located in the fuel circulation system may be used as a source of heat for the heat exchanger, as well as the vehicle interior, when the engine is not operating.
