  • Patent number: 5411005
    Abstract: A fuel heating system which employs an improved heat exchanger for reducing particulate emissions in diesel or kerosene fuel powered internal combustion engines. The fuel heating system encompasses an internal combustion engine having a fuel line, a cooling system having a coolant line, and the novel heat exchanger of this invention. The heat exchanger has a container for holding heated coolant to provide a heat source for the fuel. A helical fuel tube extends the length of the container, with its inlet and outlet ports located in close proximity at the same end of the container. The coolant inlet and outlet ports are located on opposite ends of the container, with the coolant inlet port located on the same end of the container as the fuel ports. The coolant outlet port is located at a higher elevation than the coolant inlet port to prevent air lock.
