摘要： The invention relates to a method and an apparatus for determining an exhaust gas recirculation rate in an internal combustion engine, in which the exhaust gas recirculation rate indicates a proportion of exhaust gas in a gas quantity delivered to a cylinder of the internal combustion engine, and combustion takes place in the cylinder of the engine cyclically during a combustion phase. The method includes the steps of ascertaining a combustion course statement over the course of combustion in the cylinder of the engine, and ascertaining an actual exhaust gas recirculation rate from the combustion course statement with the aid of a predetermined exhaust gas recirculation rate function. The invention further relates to a method and an apparatus for regulating an exhaust gas recirculation rate in an internal combustion engine, in which the exhaust gas recirculation rate indicates a proportion of exhaust gas in a gas quantity delivered to a cylinder of the internal combustion engine, and combustion takes place in the cylinder of the engine cyclically during a combustion phase. The method includes the steps of ascertaining a combustion course statement over the course of combustion in the cylinder of the engine, furnishing a set-point statement as a function of an operating point of the engine, and performing a regulation to compensate for a deviation that results from the set-point statement and the combustion course statement.

To achieve this aim, the individual cylinders are synchronized with respect to their torque contribution. According to the method, fuel is injected into the combustion chamber of a cylinder in at least one injection step, the at least one injection contributing to the torque of the internal combustion engine. Fuel is injected into the combustion chamber of the cylinder in a torque neutral manner by way of a secondary injection during a working stroke of the cylinder and the amount of fuel of the secondary injection us calculated in such a manner that the exhaust gas substantially corresponds to a stoichiometric air/fuel mixture.

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.
摘要翻译：内燃机通过直接燃料喷射进入燃烧室来操作。此外，内燃机以次最佳点火角效率和要在燃烧开始之前喷射的燃料量的分配进行至少两次局部喷射。通过燃烧室的增加的电荷补偿由次最佳点火角效率和/或来自待喷射的燃料的分配产生的扭矩损失。燃料量和电荷彼此协调，使得燃烧室充气的空气比λ大于1.该方法的特征在于，催化转化器的温度，特别是一种测量对于催化转化器的入口处的温度是确定的，并且如果温度的测量超过预定值，则通过至少一个干预内燃机的控制来增加一定量的还原废气组分温度阈值。根据本发明的方法允许催化转化器的快速加热，其中当催化转化器冷时的碳氢化合物排放量尽可能低的同时。

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.
