ABSTRACT:
A system for reducing air pollutants expelled from a standard internal combustion engine coupled with an increase in fuel economy wherein a supplemental oxygen supply is introduced into the carburetor of an internal combustion engine while the fuel supply is reduced. The supplemental oxygen supply is regulated via a variable control valve and a safety shut off valve. The safety shut off valve is activated independently by both the engine ignition switch and one or more engine parameters which are only activated when the engine is in actual operation. This only allows oxygen to pass through the safety shut off valve when the engine is running and automatically stops the oxygen flow when the ignition switch is turned off or in case of inadvertent or accidental engine shut down.
