Abstract
A method for regenerating a particulate filter is disclosed. In one example, oxygen is pumped from the intake system of a direct injection turobocharged gasoline engine through a cylinder and into the exhaust system by a compressor. In this way, regeneration of a particulate filter may be accomplished without an auxiliary air supply.
