Definitions
- the invention relates to a method and a device for operating an internal combustion engine with gasoline direct injection.
- EP 0 838 582 already discloses a method for controlling the intake of a four-stroke engine known with direct injection gasoline, in which two cylinders or groups different from cylinder through a different inlet of air and fuel work.
- One cylinder group works with a rich mixture and the other with a skinny one.
- To reduce the pollutant emission is a part of the exhaust gas of the fat-operated cylinder group is recirculated to an inlet common to all cylinders.
- a method and apparatus for operating an internal combustion engine with gasoline direct injection is also described in DE 43 32 171 A1 (US Patent 5,483,934).
- Control system shown there is the entire operating range of the internal combustion engine after Speed and load divided into different areas and depending on the current operating range the fuel is injected either during the intake stroke or during the compression stroke. Injection during the intake stroke is due to the available standing time to ignition and due to the swirling of the injected Fuel through the intake air flow a largely homogeneous fuel distribution (Homogeneous operation), while in the case of injection in the compression stroke a stratified charge arises (shift operation). In homogeneous operation, the internal combustion engine is operated throttled, i.e.
- the air supply is limited by a throttle valve, in stratified charge mode almost unthrottled operated throttled, i. the air supply through the throttle almost unlimited. Between these modes depends on the mentioned operating variables and / or of other predetermined criteria, e.g. in terms of performance requirements by the driver, switched.
- Another advantage of such asymmetric operation the internal combustion engine is achieved is an improvement the noise emission or, more generally, the comfort of the Internal combustion engine.
- Particularly advantageous in this context that when clearing a storage catalyst in Idle or in the partial load range, not all banks at the same time be switched. By switching alternately the noise emission is optimized.
- the power request becomes the driver implemented so that a part the internal combustion engine in an exhaust gas-optimal mode and operated at an exhaust gas-optimal operating point, while the actual power requirement of the driver by controlling the operating point and possibly the Operating mode of another part of the internal combustion engine is carried out.
- FIG. 1 shows an overview diagram of a control device for Control of an internal combustion engine with gasoline direct injection.
- Figure 2 is based on an embodiment of a Flowchart illustrating the principle of asymmetric Represents operation of such an internal combustion engine.
- FIG. 3 shows a further exemplary embodiment which is a preferred embodiment outlined as a flow chart.
- FIG. 1 shows a block diagram of a control device for controlling an internal combustion engine with gasoline direct injection. It is a control unit 10 is provided which as Components an input circuit 14 at least one microcomputer 16 and an output circuit 18. One Communication system 20 connects these components to each other Data exchange.
- the input circuit 14 of Control unit 10 are supplied to input lines 22 to 26, which in a preferred embodiment as Bus system are executed and via the control unit 10th Supply signals which are used to control the internal combustion engine represent operating variables to be evaluated. These signals are detected by measuring devices 28 to 32.
- Operating variables are accelerator pedal position, engine speed, engine load (e.g., air mass), exhaust gas composition, engine temperature, etc.
- About the output circuit 18 controls the controller 10 the performance of the internal combustion engine with gasoline direct injection. This is shown in FIG.
- FIG. 1 on the basis of the output lines 34, 36 and 38 symbolizes which at least the fuel mass to be injected, the ignition angle of the internal combustion engine and at least one electrically operable Throttle valve for adjusting the air supply to the internal combustion engine actuate.
- the representation chosen in FIG. 1 means in that on the symbolic output line 34th the injectors of a certain number of cylinders the internal combustion engine are actuated, i. the injected Fuel mass is supplied to these cylinders, over the output line 36 of the spark in these cylinders to predetermined time is triggered and an electric Actuatable throttle is controlled, which controls the air supply affected to these cylinders.
- the two control units 10 and 10b are via a communication system connecting them 40 for mutual exchange of data with each other. At least one person will be able to use this communication system the control units depending on the embodiment individual or all of the other detected magnitude data signals or from these derived operating variables for further Evaluation transmitted.
- Input lines 22b to 26b are next to the controller 10 also supplied to the control unit 10b, so that there alternatively for transmission over the communication system or in addition the operating variable signal is directly available.
- the basic procedure for those in the microcomputer 16 of the control unit 10 running control of the internal combustion engine is sketched with reference to the flowchart of Figure 2.
- essential operating variables are the microcomputer 16 the accelerator pedal position ⁇ and operating variables such as engine speed NMOT, air mass MHFM and set torques of others Control systems, for example, by a traction control system and / or a transmission control supplied.
- the driver request pictures 100 is from the supplied accelerator pedal position signal ⁇ at least taking into account the engine speed, optionally a correction variable of an idle speed control, etc., a driver's request moment MIFA the Internal combustion engine determined. This is done in the preferred Embodiment by means of a map and the following Calculation steps.
- the microcomputer 10 Desired torques of other control systems, e.g. a desired moment of a Drive slip control MIASR, a transmission control MIGS, etc. supplied. These desired torques and the driver's desired torque are fed to a selection stage 102, in which from the supplied Set torques a resulting desired torque MISOLL For controlling the internal combustion engine is determined. In the preferred Embodiment, the selection is made by minimum or maximum selection. The determined in this way resulting target torque MISOLL becomes another coordinator 104 supplied, in which the following with reference to Flowchart of Figure 3 described specifications for a asymmetric operation of the internal combustion engine can be determined.
- the coordinator 104 sets the total target torque MISOLL in individual rolling moments MISOLL1 to MISOLLN for the individual Cylinder banks or for individual cylinder groups and / or in Desired modes BASOLL1 to BASOLLN of the individual cylinder banks or cylinder groups.
- the division of the target torque and the specification of desired modes by the Coordinator 104 takes place according to predetermined strategies.
- Another strategy used in coordinator 104 in one embodiment implemented is a comfort optimization, after the switching of individual cylinder banks or Cylinder groups never change from one mode to another simultaneously but temporally one after the other. Thereby, the noise emission associated with the switching becomes reduced.
- an exhaust gas-optimal Strategy (e.g., in the area of low power requirements) be used.
- the division takes place the torques and / or the specification of the desired mode such that the lowest possible exhaust pollution occurs. It is thus e.g. tries the total target torque as long by lean operation in the shift and / or homogeneous operation ready as long as with the respective operating mode this moment is adjustable. Only then is at a cylinder bank or group by specifying a different one Sollmoments and / or a desired mode a less exhaust gas optimal Operating point set.
- the individual desired torques MISOLL1 to MISOLLN and the corresponding Desired modes become the respective control signal images 106 to 108 for the individual cylinder banks or cylinder groups supplied, in which, taking into account of operating variables such as engine speed, relative air charge (derived from the supplied air mass), etc. the respective nominal torque taking into account the desired Operating mode in a fuel mass to be injected, a Ignition angle and a throttle position can be implemented. It may happen that the desired mode is not can be met, for example, when a runflat situation present, with no adjustability of the Nominal torque, with special operating functions such as start, warm-up, Katformingen, etc.
- FIG. 2 shows a system in which for each Cylinder bank or group can control its own throttle is.
- the mode of operation for each bank are freely chosen and the torque requirements so on the Banks are distributed, that is optimal efficiency the internal combustion engine or depending on the strategy an optimal Operation of the internal combustion engine results. Owns the internal combustion engine only one throttle, so this is so adjust that results in an air filling, it by appropriate calculation of the fuel mass allowed, a Cylinder bank homogeneous and another cylinder bank layered to operate. This is one over the homogeneous Operation of the internal combustion engine as a whole increased air charge adjusted, which throttle losses are reduced. A quick change of the operating mode of the cylinder banks by controlling the fuel mass is possible here.
- An embodiment of the coordinator 104 is based on the Flowchart of Figure 3 the example of an internal combustion engine with two independently controllable cylinder banks or - groups outlined in more detail.
- the program is given in Go through time intervals.
- the next step 202 will be on the Based on this target torque checks if an increased power requirement is present. In a preferred embodiment this is the case when the nominal torque exceeds a predetermined limit. This threshold is sized so that it is approximately a borderline corresponds, above which the internal combustion engine with homogeneous Mixture be operated for performance reasons would.
- a predetermined limit is sized so that it is approximately a borderline corresponds, above which the internal combustion engine with homogeneous Mixture be operated for performance reasons would.
- the power request is so high that all cylinder banks or switch groups. This is the case when a desired torque value is required, which is close to the maximum value lies.
- step 206 initially as the desired mode of the first bank or cylinder group BASOLL1 the homogeneous mode output and a Setpoint torque value MISOLL1 for this cylinder bank or group determined.
- This setpoint torque value is in a preferred Exemplary embodiment based on the total nominal torque value, which is read in step 200 formed. Especially is a percentage of this nominal torque value> 50% specified.
- step 208 based on a If necessary, the notified mark checks whether the switchover finished.
- step 210 it will be in step 210 also for the second cylinder bank or cylinder group as Desired mode of homogeneous operation output and the Target torque of this cylinder bank or group on the basis the Bactsollmoments and the desired torque of the first cylinder bank or group determined.
- the switchover the first Cylinder bank according to step 208 is not yet finished is in step 212, the desired mode of operation of the second cylinder bank recorded on stratified charge mode and as desired torque value according to step 210, the difference between the total desired torque value and the desired torque value of the first Bank determined.
- Step 214 outputs the formed setpoints and if no higher-level specifications, e.g. Emergency operation, missing Feasibility of the setpoint torque value in the desired operating mode, etc., realized. After that, the program part finished and again at the next time interval run through.
- Step 216 the target mode of a bank on the homogeneous operation, that of the other bank on the stratified charge operation set.
- the target moment of a bank the is to be operated homogeneously, formed analogously to step 206, while the target moment of the other bank, in the Stratified charge operation, based on the total desired torque and the target torque of the first bank becomes.
- step 214 asymmetric operation of the internal combustion engine becomes a consumption-optimal control of the internal combustion engine achieved with increased performance requirement, as a Part of the internal combustion engine continues in fuel-efficient Stratified charge operation is operated.
- step 226 it is checked whether the conditions for Clearing a storage catalyst present. Are the conditions cleared for, is in step 228 for a cylinder bank as a desired mode of homogeneous operation output and a corresponding desired torque (for example, minimum desired torque for this operating mode).
- Step 230 is called the other bank's desired mode furthermore, the stratified charge mode is output and the setpoint torque based on the total desired torque and the desired torque the first bank. This is followed by step 214.
- step 218 the target mode of the first bank on stratified charge mode and a corresponding one Target torque determined from the setpoint torque value specified. This corresponds in a preferred embodiment 50% of the total setpoint torque value read in step 200.
- step 220 becomes checks, if necessary, the switchover from shift to Homogenous operation is completed. If this is the case, it will Step 222 also the second cylinder bank to the desired mode Layer charge set and the corresponding Setpoint based on the total setpoint torque value and the setpoint torque value of the first bank formed. Is the switch not completed in step 220, i. is the system becomes the second bank in step 224 as previously controlled and the setpoint torque value formed analogous to step 222. By this measure prevents both banks from switching simultaneously and in this way loss of comfort. After that follows Step 214.
