Fuel filter for diesel engine
A fuel filter is described for use in a diesel engine having a fuel injection pump, the fuel filter comprising; a fuel filter body having a center tube, an inlet port to receive fuel from a fuel tank and connected to supply such fuel to the center tube, and an outlet port to supply filtered fuel to the fuel injection pump; a filter element located coaxially of the center tube through which fuel received from the center tube is filtered before being supplied through the outlet port to the fuel injection pump; means on the filter body defining a fuel introduction port to receive a part of warmed fuel overflowing from the fuel injection pump and connected to supply the warmed fuel to the center tube to be mixed with fuel supplied from the tank; a check valve disposed in the fuel introduction port and operable to allow the warmed fuel to flow therethrough; and a bimetal element operatively connected to the check valve and mounted on the filter body to sense temperature of fuel flowing through the center tube. The temperature sensing causes the check valve to open in response to a predetermined temperature thereof and adjust the proportion of the warmed fuel supplied to the center tube for filtering by the filter element.
