Definitions
- the invention relates to a method and a device for operating an internal combustion engine.
- a first measured value of a load variable of the internal combustion engine is detected.
- a first model value of the load variable is determined by means of an intake manifold model.
- At least one parameter of the intake manifold model is adjusted by means of a parameter trimming such that the first model value approaches the first measured value of the load variable or corresponds to the first measured value of the first load variable.
- a first value of the parameter trim by which the parameter of the intake manifold model is adapted in the first operating point of the internal combustion engine, is stored.
- An internal combustion engine is basically designed so that it has the lowest possible fuel consumption at the highest possible power and / or the lowest possible emission of pollutants. For this purpose, it is necessary, for example, to know as accurately as possible an air mass flowing into a combustion chamber of a cylinder of the internal combustion engine. This can be determined, for example, by means of an intake manifold model as a function of an opening degree of a throttle flap of the internal combustion engine. If the internal combustion engine comprises an external exhaust gas recirculation line with which exhaust gas from an exhaust gas tract of the internal combustion engine can again be supplied to a combustion process in the combustion chamber, then so The fresh air mass flowing in via the throttle valve and the recirculated exhaust gas mass flow into the cylinder.
- the recirculated exhaust gas mass can be determined, for example, by means of an exhaust gas recirculation model.
- the exhaust gas recirculation model is similar to the intake manifold model, with only the parameters, for example a cross-sectional area of an exhaust gas recirculation valve being adapted, and / or where, for example, an opening degree of the exhaust gas recirculation valve is a typical input variable of the exhaust gas recirculation model.
- the object on which the invention is based is to provide a method and a device for operating an internal combustion engine, which simply make it possible to adapt an exhaust gas recirculation model of the internal combustion engine.
- the invention is characterized by a method and a device for operating an internal combustion engine.
- a first measured value of a load variable of the internal combustion engine is detected.
- a first model value of the load variable is determined by means of an intake manifold model.
- At least one parameter of the intake manifold model is adjusted by means of a parameter trimming so that the first model value approaches the first measured value of the load variable or corresponds to the first measured value of the load variable.
- a first value of the parameter trimming, by which the parameter of the intake manifold model is adapted in the first operating point of the internal combustion engine without exhaust gas recirculation, is stored.
- a second measured value of the load size is recorded.
- a second model value of the load variable is determined by means of the intake manifold model.
- the parameter of the intake manifold model is adjusted by means of the parameter trimming, so that the second model value approaches the second measured value of the load variable or corresponds to the second measured value of the load variable.
- a second value of the parameter trimming by which the parameter of the intake manifold model is adapted in the second operating point of the exhaust gas recirculation engine, is stored.
- the first and second stored values of the parameter trimming are compared.
- a parameter value of an exhaust gas recirculation model of the internal combustion engine is adapted such that the first and second values of the parameter trimming approach each other or correspond to one another.
- the adaptation of the exhaust gas recirculation model contribute to the fact that an air mass flowing into a cylinder of the internal combustion engine comprising a fresh air mass and a recirculated exhaust gas mass can preferably be determined particularly precisely.
- the load size is a physical quantity of the internal combustion engine that represents a measure of the torque output by the internal combustion engine at current actuator positions, a current speed of the internal combustion engine and current ambient conditions, for example an air mass flow via a throttle valve of the internal combustion engine or an air mass flow into a cylinder Internal combustion engine or an intake manifold pressure in a suction pipe of the internal combustion engine.
- the further operating variable may in principle comprise any operating variable of the internal combustion engine, from which the first model value of the load variable is determined as a function can.
- the further operating variable includes an opening degree of the throttle valve.
- the parameter of the intake manifold model may include, for example, a reduced throttle area or a pressure upstream of the throttle.
- the exhaust gas recirculation model is similar in structure to the
- an air mass sensor detects an air mass flow or an intake manifold pressure sensor which adjusts due to the incoming fresh air mass or due to the incoming fresh air mass and due to the incoming recirculated exhaust gas mass.
- the intake manifold model is suitable for determining the inflowing fresh air mass due to at least one further operating variable. For determining the total air mass flowing into the cylinder by means of the intake manifold model, the exhaust gas recirculation model is additionally required.
- the intake manifold model is precisely matched to the incoming air mass, a deviation of the second value of the parameter trimming from the first value of the parameter trimming to an imprecise determination of the recirculated exhaust gas mass by means of the exhaust gas recirculation model is traceable during operation with exhaust gas recirculation ,
- the first value of the parameter trim must match the second value of the parameter trim.
- the values of the parameter agreement are only determined and / or compared with one another if at least one predetermined operating condition of the internal combustion engine is present. This contributes to the fact that the exhaust gas recirculation model is adapted very precisely.
- the predetermined operating condition comprises a stoichiometric operation of the internal combustion engine.
- This contributes to the fact that the exhaust gas recirculation model is adapted particularly precisely, since in stoichiometric operation, a torque of the internal combustion engine is essentially determined by the incoming fresh air mass.
- a regulation of an air / fuel ratio in a combustion chamber of the internal combustion engine is monitored prior to a combustion process. Depending on a control intervention of the control, it is automatically decided whether the adjustment of the parameter value of the exhaust gas recirculation model is maintained or discarded.
- the air / fuel ratio is preferably monitored by means of a lambda control. If the internal combustion engine is operated in stoichiometric operation, lambda is equal to one. Lambda equals one can easily be set if the incoming fresh air mass into the cylinder, on the basis of which a fuel mass to be injected is calculated, is precisely determined. If the fresh air mass flowing into the cylinder is incorrectly determined, for example due to a wrong adaptation of the parameter value of the exhaust gas recirculation model, Lambda deviates from one.

- the intake manifold model is used to determine, depending on, for example, an opening degree of the throttle valve 5 and the rotational speed of the internal combustion engine, a fresh air mass flowing into the cylinder Z1-Z4.
- the values of the parameters of the intake manifold model are first determined on an engine test bench. Since internal combustion engines of the same design are slightly different due to component tolerances and / or wear and the intake manifold model is determined only on one or more reference engines, adjusting the intake manifold model can help to compensate for the differences between the internal combustion engines of the same design.
- the first program is started in a step S1, in which variables are initialized if necessary.
- a predetermined operating condition CON is currently present.
- the predetermined operating condition CON can include, for example, a stoichiometric operation of the internal combustion engine.

- the first value PAR_1 of the parameter trimming can be the parameter itself or just a variable which changes the corresponding parameter either additively or multiplicatively.
- step S7 in a second operating point of the internal combustion engine, which coincides with the first operating point of the internal combustion engine with respect to the rotational speed and the load, a second measured value LOAD_MES_2 and a second model value LOAD MDL 2 of the load variable corresponding to the first values are determined in step S4.

- the first program can be ended.
- the first program is regularly used during operation of the internal combustion engine to adjust the
- an exhaust gas recirculation model is used to determine the recirculated exhaust gas mass flowing into the intake tract 1 as a function of an opening degree of the exhaust gas recirculation valve 24. If the intake manifold model is adjusted during operation without exhaust gas recirculation EGR, the parameter adjustments required for this must correspond to the parameter agreement during operation with exhaust gas recirculation EGR, provided that the exhaust gas recirculation model precisely supplies the recirculated exhaust gas mass. If the parameter matches at the same operating point with and without exhaust gas recirculation EGR do not match, this is due to an imprecise exhaust gas recirculation model.
- a second program for operating the internal combustion engine is preferably stored on the storage medium (FIG. 3).
- the second program serves to adapt at least one parameter of the exhaust gas recirculation model depending on the stored values of the parameter trim of the intake manifold model.
- the parameter of the exhaust gas recirculation model is, for example, the reduced area of the exhaust gas recirculation valve 24.

- the parameter value PAR_3 is determined in such a way that the second value PAR 2 of the parameter trimming approaches or corresponds to the first value PAR 1 of the parameter trimming.
- the determination of the parameter value PAR 3 can also be referred to as dimming the exhaust gas recirculation model.
- the parameter value PAR 3 can be determined, for example, on the basis of a characteristic map which can be recorded, for example, on the engine test bench.
- the second program may be terminated in a step S16.
- the second program can be continued with a check of the adapted exhaust gas recirculation model in a step S14.
- step S14 it is possible to check whether a controller intervention LAM of a lambda controller becomes smaller in size on account of the parameter trimming of the exhaust gas recirculation model. If the parameter value PAR_3 was determined incorrectly, this leads to an incorrectly determined recirculated exhaust gas mass and to an incorrectly determined fresh air mass supplied to the cylinder Z1-Z4.
- step S14 If the condition of step S14 is not satisfied, the parameter agreement of the exhaust gas recirculation model is discarded and the processing is ended in a step S16. If the condition of the step 14 is satisfied, the processing is continued in a step S15.
- step S15 the parameter value PAR3 is maintained until the parameter value is again determined.

- the second program is preferably processed regularly during operation of the internal combustion engine, in particular at different operating points of the internal combustion engine.
- the invention is not limited to the specified embodiments.
- the first and the second program be implemented in a program or be divided into other subroutines.
