Auspuffanlage fuer Kraftfahrzeuge

摘要

A system for converting the unburned or partially burned toxic compounds of the exhaust emission from an automotive gasoline-powered engine into harmless gases through re-oxidization of the emission in the exhaust system. An appropriate amount of fresh air is delivered to the exhaust system in close response to the pulsation of the exhaust pressure so that the mixture of the exhaust emission and air is after-burned satisfactorily under the varying conditions of the engine operation.
