Definitions
- the invention relates to a method for operating a
- Internal combustion engine in particular of a motor vehicle, in which fuel is injected into a combustion chamber in at least two operating modes, and in which a switch is made between the operating modes as a function of a desired operating mode.
- the invention also relates to an internal combustion engine, in particular for a motor vehicle, with a combustion chamber into which fuel can be injected in at least two operating modes, and with a control device which can be used to switch between the operating modes depending on a desired operating mode.
- Such a method and such an internal combustion engine are known, for example, from a so-called gasoline direct injection.
- There fuel is in a homogeneous operation during the intake phase or in one
- Shift operation is injected into the combustion chamber of the internal combustion engine during the compression phase.
- Homogeneous operation is preferably provided for full-load operation of the internal combustion engine, while stratified operation is suitable for idle and part-load operation. For example, depending on the desired target operating mode, such a direct-injection internal combustion engine switches between the aforementioned operating modes.
- This target operating mode results, among other things, from the respective operating state of the internal combustion engine. For example, homogeneous operation can be useful for a cold start of the internal combustion engine. In contrast, it is possible that shift operation is preferable, for example, in the event of a defect. From these operating states of the internal combustion engine, the correct operating mode for the respective point in time must be determined permanently.
- the object of the invention is to provide a method for operating an internal combustion engine, with which a flexible but nevertheless effective determination of the desired operating mode is possible.
- This object is achieved according to the invention in a method of the type mentioned at the outset by determining the desired operating mode from a plurality of operating mode requirements.
- the object is achieved in that the target operating mode can be determined from a plurality of operating mode requirements by the control device.
- Certain functions in the control unit are assigned to the various possible operating states of the internal combustion engine. These functions can trigger operating mode requirements. Functions of the same type can be combined and provided with a common operating mode requirement. An operating mode request can be limited to a specific desired operating mode, but can also include several operating modes. The operating mode requirements for all functions of the internal combustion engine are processed by the control unit. The control unit determines the target operating mode from these operating mode requirements.
- a priority is assigned to each of the operating mode requirements, and the target operating mode is determined as a function of the priorities of the operating mode requirements. In this way it is possible to weight the various operating mode requirements of the internal combustion engine. In particular, there may be operating mode requirements that relate to special
- Operating states or their functions relate, for example to the protection of components from destruction or to the emergency running of the internal combustion engine, with a higher priority than, for example, the cold start of the internal combustion engine. This weighting can be changed quickly and flexibly due to the modular structure.
- the priorities for the operating mode requirements are preferably contained in a priority list stored in the control device and can be supplemented and / or changed there at any time.
- two operating mode requirements are linked to one another, and the linking result is used further if there is at least one match in the two operating mode requirements.
- the mode request with the higher priority will continue to be used as the link result if there is no match in the two mode requests.
- the link result is then linked to the operating mode request with the next lower priority.
- An AND operation is preferably carried out.
- each of the operating modes has one Priority is assigned, and if, if more than one operating mode is set in the most recently determined linking result, that of the available operating modes is selected which has the highest priority.
- the priorities for the operating modes are preferably contained in a priority list stored in the control device and can be supplemented and / or changed there at any time.
- Operating mode requirements and the target operating mode in the form of binary data words are stored in the control device, each operating mode being represented by a specific bit in the binary data words.
- control element which is provided for a control device of an internal combustion engine, in particular a motor vehicle.
- a program is stored on the control element, which is on a
- Computing device in particular on a microprocessor, is executable and suitable for executing the method according to the invention.
- the invention is thus implemented by a program stored on the control element, so that this control element provided with the program represents the invention in the same way as the method, the execution of which the program is suitable for.
- an electrical storage medium for example a read-only memory, can be used as the control element.

- a rotatable throttle valve 11 is accommodated, via which air can be supplied to the intake pipe 7.
- the amount of air supplied is dependent on the angular position of the throttle valve 11.
- a catalytic converter 12 is accommodated in the exhaust pipe 8 and serves to clean the exhaust gases resulting from the combustion of the fuel.
- An exhaust gas return pipe 13 leads from the exhaust pipe 8 back to the intake pipe 7.
- a Exhaust gas recirculation valve 14 housed, with which the amount of exhaust gas recirculated into the intake pipe 7 can be adjusted.
- the exhaust gas recirculation pipe 13 and the exhaust gas recirculation valve 14 form a so-called exhaust gas recirculation.
- a tank ventilation line 16 leads from a fuel tank 15 to the intake pipe 7.
- a tank ventilation valve 17 is accommodated in the tank ventilation line 16, with which the amount of fuel vapor supplied to the intake pipe 7 from the fuel tank 15 can be adjusted.
- the tank ventilation line 16 and the tank ventilation valve 17 form a so-called tank ventilation.
- the combustion of the fuel in the combustion chamber 4 causes the piston 2 to move back and forth, which is transmitted to a crankshaft (not shown) and exerts a torque thereon.
- a control device 18 is acted upon by input signals 19, which represent operating variables of the internal combustion engine 1 measured by sensors.
- the control device 18 is connected to an air mass sensor, a lambda sensor, a speed sensor and the like.
- the control device 18 is connected to an accelerator pedal sensor which generates a signal which indicates the position of an accelerator pedal which can be actuated by a driver and thus the requested torque.
- the control device 18 generates output signals 20 with which the behavior of the internal combustion engine 1 can be influenced via actuators or actuators.
- the control device 18 is connected to the injection valve 9, the spark plug 10 and the throttle valve 11 and the like and generates the signals required to control them.
- control device 18 is provided to control and / or regulate the operating variables of the internal combustion engine 1.
- the fuel mass injected into the combustion chamber 4 by the injection valve 9 is controlled and / or controlled by the control device 18, in particular with regard to low fuel consumption and / or low pollutant development regulated.
- the control device 18 is provided with a microprocessor which has stored a program in a storage medium, in particular in a read-only memory, which is suitable for carrying out the aforementioned control and / or regulation.
- a so-called homogeneous operation "hom” of the internal combustion engine 1 the throttle valve 11 is partially opened or closed depending on the desired torque.
- the fuel is injected into the combustion chamber 4 by the injection valve 9 during an induction phase caused by the piston 2.
- the injected fuel is swirled by the air simultaneously sucked in via the throttle valve 11 and is thus distributed substantially uniformly in the combustion chamber 4.
- the fuel / air mixture is compressed during the compression phase in order to then be ignited by the spark plug 10.
- the piston 2 is driven by the expansion of the ignited fuel.
- the resulting torque essentially depends on the position of the throttle valve 11 in homogeneous operation.
- the fuel is injected into the combustion chamber 4 during the intake phase, as in the homogeneous operation.
- the fuel / air mixture can also occur with lambda> 1.
- a so-called stratified operation of the internal combustion engine 1 the throttle valve 11 is opened wide.
- the fuel is injected from the injection valve 9 into the combustion chamber 4 during a compression phase caused by the piston 2, locally in the immediate vicinity of the spark plug 10 and at a suitable time before the ignition point.
- the fuel is then ignited with the aid of the spark plug 10, so that the piston 2 is driven in the now following work phase by the expansion of the ignited fuel.
- the resulting torque largely depends on the injected fuel mass in shift operation.
- the stratified operation is essentially provided for the idle operation and the partial load operation of the internal combustion engine 1.
- a so-called homogeneous shift operation "hos" of the internal combustion engine 1 a double injection takes place. Fuel is injected from the injection valve 9 into the combustion chamber 4 during the intake phase and during the compression phase. Homogeneous shift operation thus combines the properties of shift operation and homogeneous operation. With the help of homogeneous shift operation, for example, a particularly smooth transition from that
- a so-called stratified heating "skh" of the internal combustion engine 1 a double injection also takes place. Fuel is injected into the combustion chamber 4 from the injection valve 9 during the compression phase and during the working phase. In this way, essentially no additional torque is achieved, but rather a rapid heating of the catalytic converter 12 is brought about by the fuel injected into the working phase. This is important, for example, when the internal combustion engine 1 is cold started.
- the control device 18 It is possible to switch back and forth or toggle between the described operating modes of the internal combustion engine 1. Such switching operations are carried out by the control device 18. A switchover is triggered by the individual functions of the internal combustion engine 1. For example, the fifth operating mode, namely stratified heating, with which the catalytic converter 12 is quickly heated to an operating temperature, can be requested during a cold start.
- stratified heating with which the catalytic converter 12 is quickly heated to an operating temperature
- FIGS. 2 and 3 show a method which can be carried out by the control device 18 and which is suitable for changing the requirements of the operating modes by various means
- the block 21 shown in FIG. 2 represents a placeholder for the method of FIG. 3.
- the method of FIG. 3 is represented in the control unit 18 by programs that are constructed in a modular manner.
- FIG. 2 a plurality of functions act on block 21. This is evident from the majority of the arrows on block 21 shown in the right-hand area.
- Homogeneous operation can be operated. It is also about the adjustability of a target torque of the internal combustion engine 1 and the compliance with desired lambda limits. Furthermore, it is the cat heating carried out by means of the fifth operating mode already described, with which the catalytic converter 12 is quickly heated, particularly when the internal combustion engine is cold started. Furthermore, it is a control of a storage catalytic converter which is optionally accommodated in the catalytic converter and which is used for the intermediate storage of Sitckoxiden is provided. This function ensures that the storage catalytic converter is discharged again in good time after loading. Furthermore, it is the function of starting or warming up, in which the internal combustion engine 1 may not be operated, for example, in the shift mode. It is also an operating mode map that is provided for normal driving. Furthermore, there may be a number of other functions that act on block 21.
- FIG. 2 shows a target byte 22 which is used to store the described operating modes of the internal combustion engine 1 in the control device 18.
- the target byte 22 has eight bits, of which three bits are not occupied.
- the internal combustion engine 1 described with reference to FIG. 1 and the method described with reference to FIGS. 2 and 3 can also be carried out with fewer or with more than five different operating modes. In this case, more or fewer bits are not occupied in the target byte 22.
- the homogeneous operation "hom”, the homogeneous lean operation “hmm”, the stratified operation “seh”, the homogeneous stratified operation “hos” and the stratified heating “skh” are each represented by one of the remaining five bits.
- the target byte 22 shown in FIG. 2 is intended to identify the target operating mode, that is to say the desired operating mode of the internal combustion engine 1. If the internal combustion engine 1 is to be operated, for example, in homogeneous mode as the desired target operating mode, the bit "hom” in the target byte 22 is set to "1", while the other four relevant bits are all set to "0". One of the relevant bits in the target byte 22 is therefore always set to "1", while the other bits are set to "0". The bit set to "1" identifies the desired target operating mode of internal combustion engine 1.
- the target byte 22, in particular the target Operating mode is determined by block 21 using the method shown in FIG. 3.
- At least one bit is set to "1" in the request byte.
- all five bits can also be set. In the first case, this means that the associated function only requests this operating mode, which is determined with the bit set. In the other case, it is irrelevant which operating mode is available for the associated function. The associated function therefore requests "pro forma” all possible operating modes. Any intermediate options are also allowed. For example, a function can request homogeneous operation, regardless of the Lambda value to be set. In this case, the bit for "hom” and for "hmm” is set to "1" in the associated request byte, but the other bits are set to "0".
- the target byte 22 and the request bytes are binary data words which are stored in the control device 18 and in which each operating mode is represented by a specific bit. It should be noted that the target byte 22 and the request bytes - as described - have different meanings and must therefore be distinguished from one another exactly.
- FIG. 4 shows a list of priorities for the
- the operating mode request of the "Monitoring" function has the highest priority "1”
- the operating mode request of the "Component protection” function has the next lower priority "2”
- the operating mode request for the "Start / Warm-up” function with priority "7” a number of other functions with corresponding subordinate priorities can follow.
- the operating mode request of the "operating mode map” function is available as the penultimate function with priority "x”. This is followed by a fixed priority list for the described operating modes with the lowest priority.
- Operating mode map is the normal operation of the internal combustion engine 1. In order for the special traps to take effect compared to the normal case, they are given a higher priority. The priority list for the operating modes, which is subordinate to the "operating mode map" function, will be discussed in more detail below.
- the associated request bytes are ANDed by the control device 18.
- the linkage result is compared with "0" by a block 24. If this comparison is positive, a switch 25 downstream of the connection point 23 is switched. The linking result of the linking point 23 is thus no longer passed on, but rather the operating mode requirement with the higher one Priority "1" passed on as link result.
- the respective linking result is passed on to a further linking point 26, at which it is AND-linked with the operating mode requirement of priority "3", that is to say with the operating mode requirement of the "emergency operation” function.
- the linking result is correspondingly compared with "0" by a block 27 in order to switch a switch 28 as a function thereof.
- the "operating mode map" function is based on a map in which the engine 1 requires
- Torque is plotted against the speed of the same.
- a request byte is stored in each point of this characteristic diagram, in which it is specified in which operating mode the internal combustion engine 1 is to generate the required torque.
- Each of these request bytes therefore contains only one set bit.
- the associated request byte is sent to an operator as a mode request with priority "x"
- Linking point 29 is given in order to be AND-linked there with the last-generated linking result.
- the linking result is compared with "0" by a block 30 in the manner already described in order to switch a switch 31 as a function thereof.
- One or more bits can be set in the now resulting linking result generated by the linking point 29.
- the linking result generated by the linking point 29, that is to say the linking result 00001100 in the above example, is fed to a block 32 according to FIG. 3, in which the one of the set operating modes with the highest priority is selected from the linking result.
- a priority list of the operating modes of the internal combustion engine 1 is shown in FIG. The aforementioned selection of the operating mode with the highest priority is based on this list of priorities. In the above example, the operating mode "see” is selected as the highest priority operating mode from the linking result.
- the target byte 22 of FIG. 2 is 00001000 and identifies the shift operator "see” as the target operating mode.
