ABSTRACT:
The amount of nitrogen oxide (NOx) and hydrocarbon emissions emanating via the exhaust during operation of a gasoline engine is reduced by dispensing to a gasoline engine adjusted to operate primarily at an air-to-fuel ratio between lambda of about 0.9 to about 1.15, a gasoline that contains a minor amount of (i) a cyclopentadienyl manganese tricarbonyl compound and (ii) an alkyllead anti-knock agent. Components (i) and (ii) are proportioned such that there is dissolved in the fuel a substantially equal weight of manganese as (i) and lead as (ii), and the amount of (i) and (ii) used in the fuel is an amount that reduces the amount of NOx and hydrocarbons in the engine exhaust on combustion of the fuel with an air-to-fuel ratio between lambda of about 0.9 to about 1.15. Lambda is the actual air-to-fuel ratio divided by the stoichiometric air-to-fuel ratio. The stoichiometric air-to-fuel ratio is a lambda value of one.
