摘要： Suggested is a procedure for heating a catalyst in the exhaust gas system of a supercharged combustion engine with direct fuel injection and variable gas exchange valve control by producing a reactive exhaust gas fuel/air mixture in the exhaust gas system, whereby an air percentage of the reactive fuel/air mixture is thereby produced that air is rinsed from a suction system of the combustion engine over its combustion chambers into the exhaust gas system. The invention distinguishes itself thereby that the combustion engine is operated in idle mode after a cold start with a greater valve overlap and/or a greater valve overlap profile than in a normal operation where the catalyst is already heated as well as with an apportionment of a fuel amount that has to be injected before a combustion into at least two partial injections per ignition and combustion chamber and with a suboptimal ignition angle efficiency.

摘要： An internal combustion engine is operated with direct fuel injection into the combustion chambers. Furthermore, the internal combustion engine is operated with sub-optimum ignition angle efficiency and an apportionment of a fuel quantity, which is to be injected before the start of a combustion, into at least two partial injections. A torque loss which results from the sub-optimum ignition angle efficiency and/or from the apportionment of the fuel to be injected is compensated by means of an increased charge of the combustion chambers. The fuel quantity and the charge are coordinated with one another in such a way that the air ratio lambda of the combustion chamber charges is greater than 1. The method is characterized in that a measure for a temperature of the catalytic converter, in particular a measure for the temperature at the inlet of the catalytic converter, is determined and in that a quantity of reducing exhaust-gas constituents is increased by means of at least one intervention into the control of the internal combustion engine if the measure for the temperature exceeds a predetermined temperature threshold value. The approach according to the invention permits rapid heating of the catalytic converter, wherein the hydrocarbon emissions when the catalytic converter is cold are at the same time as low as possible.

摘要： A method and an arrangement serve to operate an internal combustion engine equipped with an exhaust-gas turbocharger. An after-injection takes place with the overlapment of the opening angle of the inlet and outlet valves of a cylinder. The after-injection leads to an air/fuel mixture in the exhaust-gas system which is combustible. This mixture is combusted by driving an additional ignition device in the exhaust-gas system.

摘要： In a method for operating an internal combustion engine, a computer program product, a computer program, and a control and/or regulation device for the internal combustion engine, the internal combustion engine is allowed to be operated using an enriched air/fuel mixture, without exceeding a rich combustion limit of the internal combustion engine. In the process, a setpoint value for a variable characterizing the air/fuel mixture is specified in at least one operating state of the internal combustion engine. A value of at least one variable characterizing the quality of combustion is determined. The determined value for the at least one variable characterizing the quality of combustion is compared to a first specified threshold value. If the determined value for the at least one variable characterizing the quality of combustion deviates from the first specified threshold value by an amount that exceeds a second specified threshold value, then the setpoint value is corrected.

摘要： In an internal combustion engine, fuel is directly injected into at least one combustion chamber at least during a compression stroke in such a way that a stratified mixture is present in the combustion chamber. This mixture is then externally ignited. The fuel is introduced during the compression stroke by at least one main injection and an ignition injection, the ignition injection taking place immediately before an ignition and producing at least essentially no torque.
