Abstract
A fuel system for a compression ignition engine includes a high pressure pump to which fuel is supplied through a filter by a low pressure pump. A fuel heater is provided to supply heat to the fuel. Fuel is returned from the housing of the high pressure pump through a conduit which includes in a valve housing a restricted orifice. The valve housing also includes temperature responsive means which when the fuel temperature is low reduces the size of the orifice.
