    • A method and a device for operating an internal combustion engine to perform a lambda regulation without using a lambda sensor. Fuel is injected for combustion in a combustion chamber of the internal combustion engine. A first quantity of the internal combustion engine is ascertained, which allows a conclusion to be drawn about the behavior of an output quantity of the internal combustion engine, in particular of a torque. The method includes the following: a) a first fuel quantity to be injected is predefined; b) a first value of the first quantity is ascertained, which results from a fuel injection according to the first fuel quantity to be injected; c) the fuel quantity to be injected is modified from the first fuel quantity to be injected in relation to an air quantity to be supplied to the internal combustion engine (1); d) a second value of the first quantity, which results from the change in the fuel quantity to be injected, is ascertained; e) the first value of the first quantity is compared to the second value of the first quantity, and f) as a function of the comparison result, a value for an air/fuel mixture ratio for the first fuel quantity to be injected prevailing prior to the change in the fuel quantity to be injected is ascertained independently of a measured value of a sensor measuring the oxygen level in the exhaust gas.

    • The invention deals with a method for operating an internal combustion engine with engine oil as the lubricant, wherein a fuel mass flow outgassing from the engine oil is ascertained and is taken into account via a map-based pilot control during the metering of a quantity of fuel supplied to the internal combustion engine and wherein a fuel/air ratio supplied to the internal combustion engine is determined. Provision is made in the method according to the invention for a mass flow offset determined from the deviation of the fuel/air ratio supplied to the internal combustion engine from a nominal value to be taken into account when the metering of the quantity of fuel supplied to the internal combustion engine occurs during an effective duration of the map-based pilot control. The mass flow offset takes the deviation into account, which remained after the correction by a map-based pilot control of the quantity of fuel metered, on the basis of the modeled outgassing of fuel from the engine oil, and said mass flow offset balances the lambda controller in this way. The mass flow offset can by way of example have the effect of shortening the duration injection. The mixture deviations as a result of different boiling curves of the components of the fuel blend, which cannot be completely taken into account by the map-based pilot control under all operating conditions of the internal combustion engine, can in this way be compensated.
    • 本发明涉及一种用发动机油作为润滑剂来操作内燃机的方法,其中确定从发动机油排出的燃料质量流,并且在计量一定数量的发动机油时经由基于地图的先导控制被考虑 供给到内燃机的燃料,并且确定供给到内燃机的燃料/空气比。 在根据本发明的方法中提供了从供应到内燃机的燃料/空气比的偏差确定的质量流量偏移与要计算的供应给 在基于地图的先导控制的有效持续时间内发生内燃机。 基于来自发动机油的燃料的建模排气,质量流量偏移考虑到通过基于地图的先导控制计量的燃料量的校正之后的偏差,并且所述质量流量偏移平衡 lambda控制器以这种方式。 作为示例,质量流量偏移具有缩短持续时间注入的效果。 作为燃料混合物的组分的不同沸腾曲线的结果,由内燃机的所有运行条件下的基于地图的先导控制都不能完全考虑的混合偏差可以以这种方式得到补偿。
