摘要： A compression ignition engine (10) has a control system (40), one or more combustion chambers (12), and fuel injectors (42, 44) for injecting fuel into the combustion chambers. The control system controls fueling using a result of the processing of engine speed and engine load to select a particular domain for engine operation (HCCI, HCCI+CD, or CD,—FIG. 1). When the processing selects HCCI, the engine is fueled to cause alternative diesel combustion (such as HCCI) in all combustion chambers. When the processing selects CD, all combustion chambers are fueled for conventional diesel combustion. When the processing selects HCCI+CD, a first group of combustion chambers are fueled for HCCI combustion and a second group for CD combustion. Each group (G1, G2) has its own EGR valve (34, 38) and turbocharger (22, 24).

摘要： A compression ignition engine (20) has a control system (26) for processing data, one or more combustion chambers (22), and fuel injectors (24) for injecting fuel into the combustion chambers. The control system controls fueling using a result of the processing of certain data, such as engine speed and engine load, to select one of two fueling modes (HCCI, HCCI-CD) for operating the engine. When the result of the processing selects the HCCI mode, the engine is fueled to cause homogeneous-charge compression-ignition (HCCI) combustion within the combustion chambers. When the result of the processing selects the HCCI-CD mode, the engine is fueled to create a substantially homogeneous combustible charge within each combustion chamber that is compressed to auto-ignition, and after auto-ignition, more fuel is injected to provide additional combustion in the manner of the conventional diesel combustion.

摘要： An engine (10) utilizes “regular EGR cooling” when operating in HCCI mode at loads within a low load range (56, 58, 60) and “enhanced EGR cooling” that allows the engine to continue to operate in HCCI mode when engine load increases beyond loads in the low load range (64, 66, 68). When engine load increases further to a point where it enters a high load range, the combustion mode changes over to conventional diesel combustion, and exhaust gas recirculation reverts to “regular EGR cooling” (70, 72, 74).

摘要： A vortex mixing system mixes intake air with exhaust gases for exhaust gas recirculation (EGR) in an internal combustion engine. The vortex mixing system may have a vortex mixing device connected to an intake air conduit, a supply conduit, and an EGR conduit. The vortex mixing device may have a plenum disposed around a mixing conduit, which is connected to the intake air conduit and the supply conduit. The plenum is connected to one or more cross conduits and to the EGR conduit. The cross conduits extend across a mixing chamber formed by the mixing conduit. The cross conduits generate one or more vortices in the intake air. Each cross conduit has one or more outlets. The cross conduits direct the exhaust gases through the outlets into the vortices. The exhaust gases mix with the intake air in the vortices.

摘要： A compression ignition engine (10) for a motor vehicle has a control system (20) for processing data, one or more combustion chambers (12), and fuel injectors (18) for injecting fuel into the chambers. The control system controls lean-rich modulation of fueling using independent maps. One set of maps is a set of lean fueling maps, and another set is a set of rich fueling maps. The strategy is represented by a flow diagram (30) and is useful in regenerating a NOx adsorber catalyst (16) in the engine exhaust system (14) in a manner that controls torque so that the regeneration process is transparent to the operator of the vehicle.
