  • Method and apparatus for preheating fuel in vehicles powered by internal combustion engines
    Publication number: 20010025631
    Abstract: A method and apparatus for preheating fuel in vehicles powered by internal combustion engines supplied with fuel from a fuel tank. A heat exchanger is provided for indirect heating of fuel. The heat exchanger has a fuel circulation conduit with a fuel inlet and a fuel outlet. The fuel inlet is connected to a first fuel flow line originating from the fuel tank. The fuel outlet is connected to a second fuel flow line extending to the internal combustion engine. A temperature sensor is positioned in the second fuel flow line. A control unit is coupled to the temperature sensor for controlling the temperature of the heat exchanger to maintain fuel within a predetermined temperature range as sensed by the temperature sensor.
