Title:
METHOD OF IMPROVING PERFORMANCE OF EMISSION CONTROL DEVICES BY CONTROLLING EXHAUST OXYGEN CONTENT
Document Type and Number:
WIPO Patent Application WO2005077075
Kind Code:
A3
Abstract:
A method of providing extra air to the exhaust stream of an internal combustion engine. A small flow of air is diverted from the output of an air-charging device, such as a turbocharger, to an entry point upstream of an emission control device. The air is supplied in a controllable fashion so as to improve the efficiency of the emission control device.
