Abstract
Abstract An apparatus for improving fuel economy and abating exhaust gas pollution for four cycle, reciprocating piston, internal combustion engines or rotary engines, including a water reservoir, a heat exchanger for converting water from the water reservoir to steam, a conduit for conveying steam to a water trap in which steam from the heat exchanger is separated from liquids in the steam, a conduit for conveying steam from the water trap to the carburetor, a mixing chamber attached to the carburetor for mixing the steam with fuel, and a heat exchanger for heating fuel prior to the entry of fuel into the mixing chamber.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
249 words
An apparatus for improving gas economy and abating exhaust gas pollution for four cycle, reciprocating piston, internal combustion engines or rotary engines, consisting essentially of, in combination with a four cycle, reciprocating piston, internal combustion engine, the following elements: a. a water reservoir; b. a heat exchanger located within the exhaust manifold of said engine and beneath said water reservoir whereby water flowing from said reservoir through a conduit connected to said reservoir and said heat exchanger is turned to steam; c. a second conduit connecting said heat exchanger to a water trap in which steam from said heat exchanger is separated from any condensation; d. a third conduit attached to said steam trap whereby steam is passed therefrom to the gas-air mixture feed of the carburetor of said engine; e. a fourth conduit attached to said heat exchanger for heating and conveying gasoline to said gas-air mixture feed of the carburetor of said engine; f. a mixing chamber wherein said heated gasoline and said steam is mixed prior to the entry of said gas and said steam into the gas-air mixture feed of the carburetor of said engine; and g. plate means containing said mixing chamber, said plate means being located between the downstream end of said carburetor and the intake manifold of said engine, said plate means having a series of holes therein through which the gasoline and air mixture from said carburetor flows, said plate means having channels therein connecting said mixing chamber with said holes.

Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein said heat exchanger is located outside said exhaust manifold.
Claim 4
Dependent Claim
49 words
The apparatus of claim 1 wherein a second heat exchanger is connected to the exhaust manifold of said engine, and fourth conduit are connected to said second heat exchanger for heating gas prior to entry of the gas into the gas-air mixture feed of the carburetor of said engine.
Claim 5
Dependent Claim
27 words
The apparatus of claim 3 wherein valve means is connected to said fourth conduit means for regulating the flow of said gasoline through said second heat exchanger.
Claim 6
Dependent Claim
25 words
The apparatus of claim 1 wherein valve is connected to said conduit for regulating flow of water from said water reservoir to said heat exchanger.
