    • 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.

    • The invention deals with a method for operating an internal combustion engine with engine oil as the lubricant and a fuel supply by means of direct injection, wherein an air number (lambda) of a fuel-air mixture supplied to the internal combustion engine is determined. Provision is made in the method according to the invention for the internal combustion engine to be transferred to an operating state with higher fuel consumption, when a low air number (lambda) is detected in driving conditions with a high percentage of fuel ingress from a crankcase ventilation system into the fuel-air mixture. By means of this increase in the fuel requirement, the fuel, which exited the engine oil into the intake air of the internal combustion engine, can be combusted; and an increase in the exhaust gas emissions by means of incompletely combusted fuel, in which typically hydrocarbons and carbon dioxide arise, can be avoided. In a warm-up phase of the internal combustion engine, the fuel, which ingressed into the engine oil, can thus likewise be combusted, even if under certain temperature-time conditions, particularly in the partial load operating mode and during idling, more fuel is present in the fuel-air mixture than is actually required for operating the internal combustion engine.
    • 本发明涉及一种用于通过直接喷射来操作具有发动机油作为润滑剂和燃料供应的内燃机的方法,其中确定供应到内燃机的燃料 - 空气混合物的空气数量(λ)。 在根据本发明的方法中,当在具有高百分比的来自曲轴箱的燃料进入的驾驶条件下检测到低空气量(λ)时,内燃机的方法被转移到具有较高燃料消耗的操作状态 通风系统进入燃油混合气。 通过这种燃料需求的增加,将发动机油排出到内燃机的进气中的燃料可以燃烧; 并且通过不完全燃烧的燃料(其中通常出现烃和二氧化碳)可以避免排放废气排放的增加。 在内燃机的预热阶段,即使在特定的温度 - 时间条件下,特别是在部分负荷运行模式下和在空转期间,进入发动机机油的燃料同样能够燃烧,更多的燃料 存在于燃料 - 空气混合物中比实际操作内燃机所需的混合物。
