Abstract

ENGINE Hydrocarbon and carbon monoxide emission of an internal combustion engine fitted with a non-catalytic thermal exhaust reactor is substantially lowered by operating the engine lean during normal modes of engine operation and switching to rich operation during idle using restricted air injection such that the idle exhaust contains about 2-5 volume percent oxygen.
