Abstract

A system for regenerating a particulate filter is disclosed. In one example, oxygen is pumped from the intake system of a direct injection turbocharged gasoline engine to the exhaust system by a compressor. Simultaneously, exhaust gases may be pumped from the exhaust system to the intake system for the purpose of reducing NOx while regenerating a particulate filter.
