A unique process is disclosed for modifying an automobile engine to improve fuel economy and reduce harmful exhaust emissions by introducing water and an oxidizing agent, such as hydrogen peroxide, when the engine is under load. The carburetor of a standard engine is adjusted to provide a very lean air-fuel mixture and to increase the air-fuel ratio substantially (e.g., 10 to 20 percent). The amount of hydrogen peroxide injected into the engine depends on the rate of fuel flow and may be regulated by the throttle valve or intake manifold pressure. Means are provided for maintaining a supply of hydrogen peroxide including a high pressure mixing tank containing water and hydrogen peroxide and a pair of removable oxygen tanks for a continuous supply of oxygen to the tank.

A process of operating a four-stroke high-compression reciprocating-piston internal combustion engine having a series of cylinders, means for supplying ambient air from outside the engine to said cylinders, means for supplying fuel to said engine to maintain the air-fuel ratio within a predetermined range, intake and exhaust valves for controlling the flow of gases to and from each cylinder, and means for igniting the air-fuel mixture in the main combustion chamber for each cylinder, said engine having a compression ratio of at least 9:1 and being designed for normal operation with low-lead gasoline with the air-fuel ratio below 17 to 1, said process being characterized by the steps of (a) modifying the flow of air and gasoline to the engine to increase the air-fuel ratio in the main combustion chamber of each cylinder at least 10 percent to at least 18 to 1 and high enough to create ignition problems when the engine is under high load, (b) introducing into each cylinder while the engine is under high load a solution of hydrogen peroxide to cause it to mix with the air-fuel mixture in the main combustion chamber, and (c) regulating the flow of hydrogen peroxide to the engine cylinders in accordance with intake manifold pressure and engine load, the weight rate of flow of said hydrogen peroxide being at least 5 percent of that of the fuel and sufficient to promote effective combustion in the main combustion chamber of each cylinder during high-load operation.
