摘要

A filter system forming part of the fuel system of a compression ignition engine includes a housing (11) which carries a filter element (17). The housing has a first inlet (20) which opens into a chamber defined between the housing and chamber the first inlet being connected to a fuel tank, and a first outlet (23) for fuel which has passed through the element and which is connected to a fuel injection pump. The housing has a second inlet (29) which is connected to the chamber and receives heated fuel from the fuel pump and a second outlet (30) which is connected to the chamber through a port (52). The second outlet is connected to the fuel tank. A third outlet (36) is connected to the second inlet and is connected to a flame type starting aid of the engine. Valve means (38, 39) responsive to the temperature of the fuel in the chamber controls fuel flow through said port (52).
