Abstract: A valve controlled disposable container, bracket mounted on the fire wall of an internal combustion vehicle for a selective feeding of a composition comprising a mixture of 90% hydrogen peroxide, 9% water, 0.5% nitro methane and 0.5% methanol to the intake manifold or carbureter of the engine.The present invention generally relates to internal combustion engine operation, and is more specifically concerned with a system for increasing the operational efficiency thereof through the utilization of apparatus which enables the selective feeding of an engine additive uniquely adapted to effect a substantial reduction in pollutant in conjunction with an appreciable reduction in gas consumption.One of the major problems facing the auto industry at the present time is the necessity of finding effective pollution reduction means. While many systems have been proposed, and in fact put into operation, the basic deficiency with such systems is the resulting substantial increase in gas consumption.
