ABSTRACT:
An improved fuel vaporizing system includes a fuel atomizer, an air vent stabilizer and a fuel pressure regulator serially interconnected within the fuel supply line. The fuel atomizer includes a hot water jacket for receiving heated engine coolant to thus vaporize fuel passing through a coiled conduit within the jacket, and the air vent stabilizer is utilized to provide a smooth liquid fuel flow to the carburetor while preventing vapor lock. The fuel pressure regulator controls the rate of delivery of the fuel to the carburetor. Excess liquid fuel from the air vent stabilizer is passed through a cooling stabilizer before redelivery to the fuel pump.
The system may further include a hot water preheater which is thermostatically controlled to supply hot water to the fuel atomizer during that time when the engine block coolant is not sufficiently heated, and an air pump may be provided for supplying heated combustion air to the carburetor with the engine exhaust fumes being employed to heat the combustion air.
