Definitions
- the invention relates to a method for operating an internal combustion engine according to the preamble of claim 1.
- combustion engines known from practice also have an exhaust aftertreatment system in order to purify exhaust gas which is produced in the engine of the internal combustion engine during the combustion of fuel in the exhaust aftertreatment system.
- Effective exhaust aftertreatment is required to meet increasingly stringent emissions standards.
- nitrogen oxides (NOx) in exhaust gas must meet increasingly stringent limit values.
- the reduction of nitrogen oxides in the exhaust gas is carried out using catalysts, for example using SCR catalysts, wherein SCR catalysts for the conversion of nitrogen oxides as a reducing agent use ammonia.
- the ammonia can be generated in an ammonia generator and introduced into the exhaust stream.
- an ammonia precursor substance for example an aqueous urea solution
- the conversion of the ammonia precursor substance to ammonia in the exhaust gas is typically carried out using a so-called hydrolysis catalyst.
- the speed of implementation of nitrogen oxides contained in the exhaust gas in the SCR catalyst thus depends on the proportion of nitrogen dioxide in the exhaust gas.
- the use of a separate NO oxidation catalyst for the conversion of the nitrogen monoxide into nitrogen dioxide upstream of an SCR catalyst is disadvantageous because it increases the complexity of the apparatus and thus the cost of an internal combustion engine.
- the present invention has the object to provide a novel method for operating an internal combustion engine.
- an actual exhaust gas value is determined, which is dependent on the actual value of a nitrogen dioxide fraction in the exhaust gas upstream of an exhaust gas aftertreatment component of the exhaust aftertreatment system, wherein at least one operating parameter for the engine is changed such that the actual value of the nitrogen dioxide content is approximated to a corresponding nominal value of the nitrogen dioxide fraction, so that the respective exhaust aftertreatment component is operated optimally.
- the present invention it is proposed for the first time to set the nitrogen dioxide content in the exhaust gas upstream of an exhaust aftertreatment component of an exhaust aftertreatment system by changing at least one operating parameter for the engine of an internal combustion engine in order to be able to optimally operate the exhaust aftertreatment component.
- This makes it possible to use either smaller NO oxidation catalysts or to completely dispense with the use of a NO oxidation catalyst.
- the desired value for the nitrogen dioxide content is selected as a function of the load point.
- the desired value for the nitrogen dioxide fraction is determined as a function of at least one operating parameter of the engine and / or as a function of at least one operating parameter of the exhaust-gas aftertreatment system.
- the use of a load point or operating point-dependent desired value for the nitrogen dioxide content in the exhaust gas is particularly preferred because it can be used to ensure optimal operation of the engine and optimal operation of the exhaust aftertreatment system of the internal combustion engine for all load points or operating points of the internal combustion engine.
- a lambda value and / or an ignition point and / or valve timing and / or an engine compression and / or an exhaust gas fraction in the engine combustion chamber are changed in such a way as operating parameters for the engine.
- the nitrogen dioxide content in the exhaust gas can be adjusted easily and reliably.
- an actual NOx value downstream of the exhaust aftertreatment component of the exhaust aftertreatment system is detected by a NOx sensor, the actual value of the nitrogen dioxide content in the exhaust gas being determined upstream of the exhaust aftertreatment component depending on this actual exhaust gas value, this actual value of the nitrogen dioxide content being equal to the desired value of the exhaust gas aftertreatment component Sickstoffdioxidanteils is compared, and depending on this comparison, at least one operating parameter for the engine is changed so that the actual value of the Sickstoffdioxidanteils is approximated to the desired value of the nitrogen content.
- This embodiment is particularly preferred since the NOx actual value downstream of the exhaust-gas aftertreatment component can be detected simply by means of a NOx sensor.
- operating parameters for the engine are changed such that NOx raw emissions of the engine are reduced by a maximum of 15%. This makes it possible to operate the engine with a good efficiency and avoidance of an increase in fuel consumption.
- Fig. 1 a schematic representation of an internal combustion engine
- Fig. 2 is a diagram for illustrating the invention. The invention relates to a method for operating an internal combustion engine.
- FIG. 1 shows in highly schematic form an internal combustion engine 10 which comprises an engine 11 having a plurality of cylinders 12 and an exhaust aftertreatment system 13 having at least one exhaust aftertreatment component 14.
- Exhaust gas which arises during the combustion of fuel in the cylinders 12 of the engine 11 of the internal combustion engine 10, can be guided via the exhaust gas aftertreatment system 13 in order to purify the exhaust gas in the exhaust aftertreatment system 13.
- a sensor 15 Downstream of the exhaust aftertreatment system 13, as shown in FIG. 1, a sensor 15 is positioned, which may be a NOx sensor to measure NOx emissions in the exhaust downstream of the exhaust aftertreatment system 13.
- the exhaust aftertreatment component 14 of the exhaust aftertreatment system 13 may be an SCR catalytic converter, a particulate filter or even an NOx storage catalytic converter.
- an exhaust gas actual value is determined in the sense of the invention which is dependent on the actual value of a proportion of nitrogen dioxide in the exhaust gas upstream of the exhaust aftertreatment component 14 of the exhaust aftertreatment system 13.
- at least one operating parameter for the engine 1 1 is changed such that the actual value of the nitrogen dioxide content is approximated to a corresponding desired value for the nitrogen dioxide content, so that the respective exhaust aftertreatment component 14 of the exhaust aftertreatment system 13 can be operated optimally.
- the invention finds particular use in internal combustion engines 10 use whose engine 1 1 is designed as gasoline engine, in which gaseous fuel is burned. As gas fuel, natural gas is typically burned in such Otto gas engines, which contains methane as a constituent.
- the setpoint for the nitrogen dioxide content in the exhaust gas is selected depending on the load point. It is thus possible to determine the desired value for the proportion of nitrogen dioxide in the exhaust gas as a function of at least one operating parameter of the engine 11 and / or as a function of at least one operating parameter of the exhaust-gas aftertreatment system 13. Thus, it is possible to determine the desired value for the proportion of nitrogen dioxide in the exhaust gas as a function of one or more exhaust gas temperatures and depending on the efficiency of the exhaust aftertreatment system 13 and depending on the efficiency of the engine 1 1.
- a lambda value and / or an ignition timing and / or valve timing and / or an engine compression and / or an exhaust gas fraction in the engine combustion chamber is changed.
- FIG. 2 plotting the percentage of nitrogen dioxide NO 2 in the nitrogen oxides NO x of the exhaust gas for a gasoline engine above the lambda value in FIG. and depending on the load point of the engine 1 1 and the same depending on the ignition timing.
- the characteristics relate to 16 and 17 characteristics for the full-load operation of the engine 1 1, wherein in the curve 16 ignition timing is retarded and in the curve 17 ignition timing shifted to early.
- the curves 18 and 19 relate to characteristics for the partial load operation of the engine 1 1, wherein in the characteristic curve 18 ignition points are shifted late and in the characteristic curve 19 ignition points close early.
- a NOx actual value downstream of the exhaust gas aftertreatment component 14 of the exhaust gas aftertreatment system 13, which is to be operated optimally, is detected by measurement as the actual exhaust gas value with the aid of the NOx sensor 15 shown in FIG.
- the actual value of the nitrogen dioxide content in the exhaust gas upstream of the exhaust gas aftertreatment component 14 is then determined, this actual value of the nitrogen dioxide content being compared with a desired value for the same.
- at least one operating parameter for the engine 1 1 is changed such that the actual value of the nitrogen dioxide content in the exhaust gas upstream of the exhaust aftertreatment component 14 is approximated to the target value of the nitrogen dioxide content.
- the exhaust aftertreatment component 14 which is to be operated optimally by influencing the nitrogen dioxide fraction in the exhaust gas according to the invention, can be an SCR catalytic converter.
- this exhaust aftertreatment component 14 may also be a particulate filter or a NOx storage catalyst.
- the setpoint for the proportion of nitrogen dioxide in the exhaust gas is selected depending on operating point.
- the exhaust aftertreatment component 14 of the exhaust aftertreatment system 13 which is to be operated optimally as a result of the adjustment of the actual value of the nitrogen dioxide content, is an SCR catalyst
- the setpoint for the nitrogen dioxide content in the exhaust gas is preferably 50%.
- the setpoint for the proportion of nitrogen dioxide in the exhaust gas is selected such that, as a result of the operating parameters for the engine 1 1, which are changed as a function of this setpoint, the NOx raw emissions of the engine 11 are reduced by no more than 15%.
- an increase in consumption of the engine 1 1 can be avoided.
