ABSTRACT:
A gasoline preheater has a hot fluid chamber, preferably a hot water chamber, with an inlet and outlet. A gasoline chamber is disposed in heat exchanging contact with the hot fluid chamber, and also has an inlet and outlet. A thermostat has a heat sensing element in communication with the gasoline chamber. The thermostat also has a valve element communicating with the hot fluid chamber. The foregoing arrangement is so as to allow an increased hot fluid, usually hot water from a hot water cooling system of a typical gasoline engine, to flow through the hot fluid chamber in response to a decrease in temperature of gasoline in the gasoline chamber. The gasoline preheater is used in combination with a gasoline engine having a hot fluid system, typically a hot water cooling system, a carburetor, and a source of pressurized fuel, typically a fuel pump.
