摘要： A method of purging a NOx trap, located in the exhaust passage of a direct injection engine, is proposed that provides transition from a lean fuel mixture to a rich fuel mixture in a single engine cycle without substantial change in the engine air flow. This is accomplished by substantially increasing the fuel flow rate, while retarding the spark in order to avoid any noticeable change in torque. The increased amount of fuel delivered during purge emits substantially more reducing species than in previous strategies and accordingly the required duty cycle may be substantially reduced while still obtaining the same reduction of NOx without any fuel economy penalty.
摘要翻译：提出了一种清除位于直喷式发动机的排气通道中的NOx捕集器的方法，其提供了在单个发动机循环中从贫燃料混合物到富燃料混合物的转变，而发动机空气流没有实质变化。这通过大幅增加燃料流量来实现，同时延迟火花以避免任何明显的转矩变化。在净化期间输送的燃料的量增加比以前的策略中大大减少了物种，因此所需的占空比可以大大降低，同时仍然获得相同的NOx还原，而没有任何燃料经济性的代价。

摘要： A system and a method for operating an internal combustion engine at a six-stroke, eight-stroke, or greater number of strokes cycle is disclosed. The combustion of the fuel and air is accomplished in two combustion steps with at least one expansion and compression process in between the two combustions, with the second combustion occurring at a stoichiometric air-fuel ratio. The first combustion at lean air-fuel ratio provides high efficiency. The products of the first combustion are subjected to a second combustion event at stoichiometric air-fuel ratio. Consequently, high conversion efficiency of nitrogen oxides in the exhaust aftertreatment device, available at stoichiometric conditions, can be achieved.

摘要： A turbocharger system for a diesel engine includes an exhaust driven intake air compressor, a sensor for tracking the position of the engine's throttle and for generating a throttle position signal, and a water injection system for furnishing water to the engine's air intake. A controller receives the throttle position signal and operates the water injection system such that the rate of water injection will be increased in the event that the time rate of change of the throttle position signal indicates that the throttle pedal is being depressed at a rate exceeding a predetermined threshold.
