    摘要: An engine comprising an exhaust gas recirculation system, wherein a first combustion where the amount of the recirculated exhaust gas supplied to the combustion chamber is larger than the amount of recirculated exhaust gas where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of recirculated exhaust gas supplied to the combustion chamber is smaller than the amount of recirculated exhaust gas where the amount of production of soot peaks are selectively switched. The exhaust gas recirculation rate is caused to be changed in a step-like manner when switching from the first combustion to the second combustion or from the second combustion to the first combustion.

    摘要: A compression ignition type engine, wherein a first combustion where the amount of the inert gas in the combustion chamber is larger than the amount of inert gas where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of inert gas in the combustion chamber is smaller than the amount of inert gas where the amount of production of soot peaks are selectively switched between. The second combustion is performed after the engine operation is started until a catalyst arranged in the engine exhaust passage has become activated and, the first combustion is performed after the catalyst has become activated.

    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.

    摘要: The present disclosure relates to combusting fuel during cold start. 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. All or a portion of the mass of fuel directed towards the heated region of said glow plug may be ignited, and then the remainder of the fuel may be ignited by auto-ignition and/or flame propagation.

    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.
