ABSTRACT:
The diesel fuel heater is PTC energized and is for heating gelled diesel fuel to a liquid state so as to improve engine performance particularly for engine starting. The heater is compact and is preferably integrated in a fuel filter housing. The heater basically comprises a diesel fuel heater housing and a PTC mounting plate, both of which are mounted in the fuel filter housing over the filter element. A preferably annular fuel flow channel is defined between the heater housing and PTC mounting plate with the diesel fuel adapted to pass directly over the PTC thermistors as the fuel flows from housing inlet to the filter element. A spring biasing contact is disposed intermediate the heater housing and PTC mounting plate to retain the PTC thermistors in place.
