ABSTRACT:
The present invention is an unleaded fuel composition containing a major amount of a hydrocarbon base fuel of the gasoline boiling range containing an amount effective to reduce NO.sub.x emissions from electronic port fuel injected engines of ammonia or an ammonium compound. The invention also includes a method of reducing NO.sub.x emissions from electronic port fuel injected engines by feeding to the engine exhaust gases at a point between the outlet valves and catalytic converter an amount effective to reduce NO.sub.x emissions from the engines of ammonia or an ammonium compound.
