Abstract
A fuel conservation device for a combustion engine includes a heat-exchanging tube disposed through a heating coil that is contained within a housing containing coolant. The heat-exchanging tube is adapted to be coupled inline with a fuel line used to supply fuel from a gas tank to a fuel management device, such as a carburetor provided by the engine. In addition, the heating coil is configured to be coupled to an exhaust pipe coupled to the engine, so as to be heated by the hot exhaust gases generated as it operates. A radiator fluidly coupled to the housing cools the coolant, so that the fuel passing through the fuel line is maintained at a temperature just below the boiling point of the fuel.
Claims8
A fuel conservation device for a combustion engine receiving fuel from a fuel line, the engine emitting hot exhaust gases via an exhaust, the fuel conservation device comprising:
- a housing, said housing carrying coolant;
- a heating coil disposed within said housing and in at least partial contact with said coolant, said coil having an inlet and an outlet adapted to be coupled to said exhaust, so as to be heated by the hot exhaust gases, said inlet having an inlet collector disposed within the exhaust to capture the exhaust gases;
- and
- a heat-exchange tube passing through said housing and received through said heating coil, said heat-exchange tube having an inlet and an outlet adapted to be coupled inline with the fuel line;
- wherein the temperature of said heat-exchange tube is controlled by said coolant, such that fuel passing through said heat-exchange tube is heated without being boiled.
A method of conserving fuel comprising:
- providing a combustion engine having a fuel management device configured to receive fuel via a fuel line, said engine having an exhaust;
- providing a fuel conservation device having a heating coil with an inlet end and an outlet end, and a heat-exchanging tube disposed through said coil, said heat-exchanging tube having an inlet and an outlet, wherein said heating coil and said heat-exchanging tube are disposed in a housing;
- providing a coolant in said housing, so as to be in contact with said coil to control the temperature of said heat-exchanging tube;
- coupling a radiator to said housing to cool said coolant to regulate the heat emitted by said heating coil;
- coupling said inlet end and outlet end of said heating coil to said exhaust;
- coupling said inlet and said outlet of said heat-exchanging tube inline with said fuel line;
- operating said engine to emit hot exhaust gases through said heating coil;
- and heating the fuel without being boiled to a point just below its boiling point.
