Abstract

A fuel pre-heater is used for heating the fuel for internal combustion engines, especially diesel engines. The pre-heater has an elongate cylindrical outer container housing (12) an inner S-shaped baffle (36). A fuel tube (32), formed into a coil extends the length of the container, with its inlet (28) and outlet (30) exiting through the ends (16, 18) of the container. Heating medium inlet (24) and outlet nipples (26) for the container are arranged tangentially, at opposite ends of the container and oriented in opposite directions. The heating medium inlet and outlet are connected into the coolant system of the internal combustion engine while the fuel inlet and outlet are connected into the fuel line leading to the fuel injectors or carburator of the engine. The pre-heater produces with its long path and counterflow pattern highly efficient heat transfer from the cooling medium to the fuel. In preferred embodiments, an electric heater (42) may be installed on the container for prestart-up heating. A temperature sensor (46) monitors the fuel outlet temperature and controls a valve (48) in the coolant inlet (24), closing the valve when the fuel has reached the desired temperature.
