摘要： The invention relates to a method for warming up at least one catalytic converter that is arranged downstream from a spark-ignition, direct injection internal combustion engine. To this end, an exhaust gas temperature is at least temporarily increased by at least one measure, which is executed by the engine, after the conclusion (t1) of the engine start of the internal combustion engine. The measures, which are executed by the engine, consist of a multiple injection during which at least two fuel injections into the cylinder are carried out within an induction cycle and compression cycle of a cylinder of the internal combustion engine, and/or said measures consist of a spark retarding. The invention provides that the measure executed by the engine or a combination of measures having the strongest heating action is available, at the earliest, after a retardation of at least two working cycles of the internal combustion engine after the conclusion (t1) of the engine start. The method makes it possible to keep jumps in torque low, which result from the initiation of heating measures, and to provide these in a manner that can be reproduced and easily regulated. Moreover, a reliable ignition and combustion can be guaranteed during the entire warming up phase.

摘要： The invention relates to a method for detecting deterioration of at least one NOx storage catalyst arranged in the exhaust line of an internal combustion engine, whereby at least one exhaust gas constituent is detected by a gas sensor which is arranged downstream from said NOx storage catalyst and a signal corresponding to the content of said exhaust gas constituent is provided, whereupon a change in the operating mode of said internal combustion engine occurs, leading to at least one change in the lambda value with respect to the NOx storage catalyst, by at least temporarily influencing an operational parameter of the internal combustion engine. According to the invention, a) a signal trajectory of the at least one gas constituent is detected by the gas sensor during and after a change in the working mode of the internal combustion engine and b) the signal trajectory of the at least one gas constituent is compared with a predeterminable setpoint signal trajectory for the at least one gas constituent during at least one time period.

摘要： The invention relates to a hybrid vehicle comprising an internal combustion engine (20) and an electric motor (10), which can respectively produce a torque, in particular to drive a vehicle wheel. An exhaust gas system (50) is associated with the internal combustion engine (20), said system having a catalytic converter system (60, 70), whose conversion activity is dependent on predefined activity parameters. According to the invention, the value of the conversion activity is determined in a predefined time interval T_Kat. To achieve a predefined conversion threshold value for the conversion activity of the catalytic converter system (60, 70) the torque produced by the electric motor (10) is preferably increased according to requirements and the torque produced by the internal combustion engine (20) is reduced, if the value of the conversion activity lies below the aforementioned threshold value. To this end, a device (90a) is provided to control the torque produced by the internal combustion engine (20) and the electric motor (10). The invention also relates to a method for operating a hybrid vehicle.

摘要： The invention relates to a direct injection internal combustion engine, especially an Otto engine, with layered lean operation and internal exhaust-gas recirculation. According to the invention, an exhaust-gas aftertreatment for reducing Nox using an Nox storage catalyst is provided. The object of the invention is to obtain the highest possible exhaust-gas recirculation rates with the lowest HC and Nox emission values. To this end, a tumble flow is provided for the incoming fresh gases, which may contain recirculated exhaust gas from external exhaust-gas recirculation. The swirl axis of the incoming fresh gases therefore extends substantially crosswise to the piston movement. This results in an emissions-reducing, optimal mixture inside the cylinder during the layered lean operation.

摘要： The invention relates to a method of regulating the operational mode of an internal combustion engine. The internal combustion engine is linked with means that allow the regulation of the operational mode by at least temporarily influencing at least one operational parameter of the internal combustion engine. The operational mode is regulated depending on the catalyst temperature of at least one NOx storage catalyst that is located in the waste gas duct of the internal combustion engine. According to the inventive method, the operational mode of the internal combustion engine (16) is adjusted if the catalyst temperature exceeds a definable threshold temperature (GT) depending on at least one operational parameter of the internal combustion engine (16) and/or an effective catalyst state of the NOx storage catalyst (12).
