摘要： In the exhaust gas purification device of the present invention, a NO.sub.x absorbent is disposed in the exhaust gas passage of a diesel engine. At the time when NO.sub.x should be released from the NO.sub.x absorbent, a control circuit of the engine reduces the excess air ratio of the engine, and switches the combustion mode of the engine from the normal diesel combustion, in which diffusive combustion is dominant in the combustion chamber of the engine, to the combustion mode in which pre-mixture fuel combustion is dominant. By doing this, it is possible, even in a diesel engine, to reduce the excess air ratio in combustion to thereby make the air-fuel ratio of the exhaust gas lower than or equal to the stoichiometric. Thus, the regeneration of the NO.sub.x absorbent can be performed even when it is applied to a diesel engine.
摘要翻译：在本发明的排气净化装置中，在柴油发动机的排气通路内配置有NOx吸收剂。当NOx从NOx吸收剂释放时，发动机的控制电路减少了发动机的过量空气比，并且将发动机的燃烧模式从正常的柴油燃烧中转换，其中扩散燃烧主要在发动机的燃烧室，以混合燃料燃烧为主的燃烧模式。通过这样做，即使在柴油发动机中也可以减少燃烧中的过量空气比，从而使排气的空燃比低于或等于理论空燃比。因此，即使将其应用于柴油发动机，也能够进行NOx吸收剂的再生。

摘要： An adaptive method is used for LNT desulfation and regeneration. The desulfation method involves adapting the amount of sulfur loading to trigger a desulfation event in accordance with the current adsorption capacity of the LNT. The method involves monitoring the current sulfur loading and the current LNT adsorption capacity. This data is used to calculate a loading amount “trigger”, whose value varies over the LNT lifetime. Whenever this trigger amount is reached, a desulfation event is performed. The regeneration method is similar, with the baseline data and loading threshold being determined by NOx loading rather than sulfur loading.

A glow-plug may be provided within a combustion chamber having a volume including a piston, wherein the glow plug may provide a localized heated region. Air may then be provided into the chamber and compressed. A mass of fuel may also be provided into the combustion chamber, wherein an amount of the fuel mass may be directed towards the localized heated region of the glow plug, wherein the heated region of the glow plug may have a temperature T1, and the equivalence ratio of the fuel in the heated region achieves a value that the temperature T1 provides auto-ignition.

摘要： A control system for an internal combustion engine, wherein in the control system, an in-cylinder oxygen amount is calculated and a compression end temperature, which is a temperature of the pressurized air-fuel mixture, is calculated according to an intake air temperature. A fuel injection parameter is determined according to the compression end temperature, the in-cylinder oxygen amount, and an engine rotational speed. The fuel injector is controlled based on the determined fuel injection parameter. By determining the fuel injection parameter according to the compression end temperature in addition to the in-cylinder oxygen amount, the combustion state is adjusted when the compression end temperature is low, thereby maintaining a stable combustion state.
