    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 two methods for controlling a fuel metering of a direct-injection internal combustion engine (10) in a multiple injection operating mode according to which at least two fuel injections into a cylinder (12) are carried out during a compression cycle of the cylinder (12) of the internal combustion engine (10) by means of at least one injection valve (22). The invention provides that a pressure (rail pressure, pR), under which the fuel is stored in front of the injection valve (22), is preset in such a manner and/or injected fuel portions of the individual injections of a combustion cycle and/or a total fuel quantity, which is injected during a multiple injection, are varied in such a manner as to prevent a forthcoming valve opening time (Δt) of the injection valve (22) from falling below a preset valve opening time (ΔtK) during at least one injection of a combustion cycle. The inventive measures ensure, with simple means, a precise fuel metering in the multiple injection operating mode and thus enable an application of the multiple injection operating mode over wide operating ranges, particularly also in the low load operating mode and idle operating mode.

    摘要： The invention relates to an exhaust gas system (110) of an internal combustion engine, especially of an automobile, comprising a catalyst (113), especially an Nox storage catalyst. A cooling section (112) is provided upstream of the catalyst (113). Said cooling section (112) comprises several separate exhaust gas lines (114) and/or additional cooling means (33; 34; 36) are provided on the cooling section in such a way that in all of the respective operating phases of the internal combustion engine, with different exhaust gas mass flows, a heat energy output from the exhaust gas in relation to the heat energy contained in the exhaust gas (relative heat energy output) increases in such a way that a maximum temperature drop is established for average values of the exhaust gas mass flow.

    摘要： The invention relates to a method for controlling an internal combustion engine (10) consisting of at least one catalyst arranged in the exhaust channel (14) of the internal combustion engine (10), and a lean operating internal combustion engine (10). According to the invention, when a substochiometric lambda value is required directly after a thrust disconnection phase of the internal combustion engine(10) and/or directly after an operating phase in which oxygen is stored in the catalyst, an approximately stochiometric or less substochiometric lambda value is initially adjusted in a transition phase and is subsequently brought down to the required substochiometric lambda value.

    摘要： The invention relates to a method for controlling an operation of a motor vehicle equipped with a hybrid drive unit (10), which comprises a combustion engine (12) and at least one electric machine (14) that can be operated by a motor or by a generator. This electric machine (14), when in generator mode, charges an energy accumulator (22) and/or supplies power to a vehicle electric system (24) of the motor vehicle. The invention provides that, according to the maintaining of preset boundary conditions, the operation of the electric machine (14) in the generator mode ensues in alternating intervals, whereby: (a) in a first interval, the electric machine (14) is operated with a first high electrical power output that is higher than an actual power consumption of the vehicle electric system (24) of the motor vehicle and; (b) is switched off in a second interval. This enables the starting of light load operating points of the electric machine (14) with low efficiencies to be largely avoided whereby achieving a fuel advantage with regard to a continuous operating mode.

    摘要翻译： 一种方法控制配备有具有内燃机的混合动力驱动单元的机动车辆和可以选择性地作为电动机或发电机操作的至少一个电动机的操作。 电动机在发电机模式下向机动车辆的车辆电气系统充电并向其供电。 在发电机模式下，电机以交替的间隔运行，同时保持预定义的边界条件。 在第一间隔期间，电机以高于机动车辆的车辆电气系统的实际功率消耗的第一高功率输出来操作。 电机在第二个时间间隔内关闭。 这大大地防止电机在轻负载下接近工作点，其效率低并且与连续操作模式相比获得了燃料优势。
