Provision is, thereby, made for a variation, which is individually adjusted to each cylinder, of the quantity of fuel delivered to the cylinder to be implemented to supply a lean and/or to a rich air/fuel mixture at least one cylinder, for the effect of the variation on the starting characteristics and/or the running smoothness of the cylinder and/or the internal combustion engine to be evaluated and when an improvement in the starting characteristics and/or the running smoothness is achieved, for a fuel adaptation to be implemented for all cylinders. The method makes the quick detection and the avoidance of starting problems possible, when a change in the fuel quality or in the fuel composition occurs with an effect on the ignitability of the fuel.

摘要： To achieve a reliable and exhaust-optimized combustion starting already from the beginning of a combustion phase in the startup of an internal combustion engine, the internal combustion engine is brought to a target speed by an electric motor in a drag phase, the target speed being higher than the previously known starting speed. The target speed corresponds approximately to an idling speed assigned to the internal combustion engine, for example. After exceeding the starting speed, first a mixture enrichment is determined, taking into account a prevailing state of a wall film here in particular. Only after reaching the target speed is the fuel metered and does the combustion take place in the combustion phase. The fuel is metered here in particular on the basis of the mixture enrichment determined after exceeding the starting speed.

摘要： The invention relates to a method for operating an internal combustion engine, which can be operated with fuels and fuel mixtures of said fuels, said fuels differing from each other in the air quantity they require for a stoichiometric combustion. A fuel quantity to be supplied to the internal combustion engine is corrected via a mixture adaptation and a fuel adaptation, the mixture adaptation and the fuel adaptation being based on a lambda control and a fuel quantity contained in the fuel reservoir of the internal combustion engine prior to refueling and a fuel quantity supplied to the reservoir being determined. The method is characterized by using the change of the fuel adaptation after refueling towards a fuel/air mixture having a higher or a lower fuel percentage to extrapolate the supplied fuel or the supplied fuel mixture and the fuel quantity present in the reservoir and the knowledge of the nature of the fuel or the fuel mixture supplied to the reservoir are used to calculate the fuel mixture ration in the reservoir after refueling. The method according to the invention allows determination of the fuel mixture ratio in the reservoir of internal combustion engines which can be operated with different fuels.

摘要： The invention deals with a method to determine the fuel composition of a fuel mixture from a first fuel and a second fuel for the operation of an internal combustion engine, wherein the first and the second fuel have different octane numbers and wherein the internal combustion engine has at least one knock sensor and a closed-loop knock control. Provision is made according to the invention for the composition of the fuel mixture to be determined by means of an output signal of the knock sensor. Provision is made in many cases for the knock sensor to already be in the internal combustion engine, so that it does not present any additional expenditure of money or effort. Because the octane number of the fuel mixture is determined by the mixing ratio of the fuels involved, which have different octane numbers, in retrospect the composition of the fuel mixture can be suggested from the signal of the knock sensor under suitable operating conditions.

摘要： 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.

摘要： The aim of the invention is to optimize the running smoothness of an internal combustion engine. 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.
