  • SYSTEM AND METHOD FOR REGENERATING A PARTICULATE FILTER FOR A DIRECT INJECTION ENGINE
    Publication number: 20110072794
    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 to the exhaust system by a compressor. The oxygen is introduced to a particulate filter at a location upstream from the particulate filter. In this way, regeneration of a particulate filter may be accomplished without disturbing the chemistry of a three-way catalyst located in the exhaust system upstream of the particulate filter.

  • METHOD FOR CONTROLLING SPARK FOR PARTICULATE FILTER REGENERATING
    Publication number: 20110073070
    Abstract: A system for filtering and oxidizing particulate matter produced by a gasoline direct injection engine is disclosed. In one embodiment, engine spark is controlled such that soot held by a particulate filter may be oxidized even during low engine loads.

  • FUEL CONTROL FOR SPARK IGNITED ENGINE HAVING A PARTICULATE FILTER SYSTEM
    Publication number: 20110072787
    Abstract: A system for filtering and oxidizing particulate matter produced by a gasoline direct injection engine is disclosed. In one embodiment, engine cylinder air-fuel is adjusted to allow soot to oxidize at an upstream particulate filter while exhaust gases are efficiently processed in a downstream catalyst.

  • SYSTEM FOR REGENERATING A PARTICULATE FILTER AND CONTROLLING EGR
    Publication number: 20110072804
    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.

  • METHOD FOR ADJUSTING BOOST PRESSURE WHILE REGENERATING A PARTICULATE FILTER FOR A DIRECT INJECTION ENGINE
    Publication number: 20110072803
    Abstract: A method 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. The oxygen is introduced to a particulate filter at a location upstream from the particulate filter and downstream of a three-way catalyst. The oxygen may be regulated in part by adjusting compressor boost pressure in response to a state of particulate filter regeneration. Further, in one embodiment, engine NOx can be controlled by EGR.

  • METHOD FOR REGENERATING A PARTICULATE FILTER FOR A BOOSTED DIRECT INJECTION ENGINE
    Publication number: 20110072795
    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.
