摘要： A valve for an internal combustion engine has a valve stem, a valve cone and a valve disk, with the valve cone having a recess to receive the valve disk, and the valve cone and valve disk together forming a cavity. The valve disk has a lesser diameter than the recess in the valve cone, so that an insulation gap is formed between the recess in the valve cone and the valve disk edge. As a result the valve cone and valve stem are thermally insulated relative to the valve disk, which results in an advantageous, lower operating temperature at the valve cone. Particularly in the case of direct-injection internal combustion engines, this reduces the tendency to coking at the valve cone.
摘要翻译：用于内燃机的阀具有阀杆，阀锥和阀盘，阀锥具有用于容纳阀盘的凹部，并且阀锥和阀盘一起形成空腔。阀盘具有比阀锥体中的凹部更小的直径，使得在阀锥体中的凹部和阀盘边缘之间形成绝缘间隙。因此，阀锥和阀杆相对于阀盘热绝缘，这导致阀锥处的有利的较低的操作温度。特别是在直喷式内燃机的情况下，这降低了阀锥处的焦化倾向。

摘要： 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.

摘要： 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.
