Definitions

  • the present invention relates to a method for adjusting a boost pressure of an internal combustion engine according to the features in the preamble of patent claim 1.
  • a method for operating an internal combustion engine in which fresh air is compressed by a pressure wave supercharger, wherein at least one operating parameter of the pressure wave supercharger, depending on at least one actual operating variable of the internal combustion engine is controlled or regulated.
  • the method disclosed therein means a departure from the previous rigid and essentially uncontrolled or uncontrolled operating concepts of pressure wave loaders.
  • a pressure wave supercharger arrangement wherein an inflow to a gas pocket is branched off from an exhaust gas supply channel and this inflow is controlled in dependence of the boost pressure via a gas pocket valve.
  • the gas pocket valve itself is controlled via a control line.
  • the gas pocket inflow is thereby realized by avoiding gas blow-off from the high-pressure duct into the atmosphere at standstill and in emergency operation of the internal combustion engine by opening the gas pocket inflow by means of spring means.
  • a pressure wave supercharger arrangement is known in which a rotatable cold gas housing is arranged to improve the performance of the pressure wave supercharger and the internal combustion engine to each other.
  • the rotatable cold gas housing is adjusted during operation of the pressure wave supercharger to improve the operation of the pressure wave supercharger over the entire map range of the internal combustion engine.
  • thermodynamic state variables Due to the pressure differences between the intake tract and the exhaust gas tract, a gas-dynamic process is formed in the rotor cells of the pressure wave supercharger itself, which produces a virtually infinite number of thermodynamic state variables. Since these are often only calculable through very long and very complex numerical equations, a detailed modeling of a pressure wave loader, which could be implemented on a control unit, is not possible with today's CAE methods.
  • Object of the present invention is therefore to provide a method for controlling and regulating a pressure wave supercharger, which optimizes the emission behavior, the response, the durability and the efficiency of a pressure wave supercharger for an internal combustion engine while allowing a largely independent of external influences series use.
  • the inventive method for adjusting a boost pressure of an internal combustion engine wherein the boost pressure is constructed by a pressure wave supercharger having a cell rotor and a cell rotor housing and the pressure wave supercharger a channel 1 for sucking fresh air, a channel 2 for discharging the compressed fresh air, a channel. 3 for supplying exhaust gas and a channel 4 for discharging exhaust gas are connected and the pressure wave supercharger has a cold gas housing, are connected to the channel 1 and 2, and a gas pocket valve, which is arranged in the region of the channel 3, characterized by, a position of the actuating element is set and / or regulated as a function of a difference between the actual value and the nominal value of the gas pocket valve position.
  • the adjusting element is a rotatable housing, an adjusting element, an edge slider or a control roller which variably change the inlet and outlet openings via a geometric offset of channel 3 and channel 4 to channel 1 and channel 2 can.
  • the adjusting element is arranged in the context of the invention on the cold gas side of the pressure wave supercharger. However, it can also be arranged on the hot gas side.
  • the gas pocket valve which is arranged in the region of channel 3, further comprises a blow-by valve which regulates the gas flow rate in a channel 3 '.
  • the channel 3 ' adjacent to channel 3 and also leads directly into the rotor cell of the cell rotor. Via the gas pocket valve, a variable opening from 0 to 100% of the channel 3 'is possible.
  • the gas pocket valve can also form a direct bypass between channel 3 and channel 4 in the context of the invention. Also can be variably controlled via the gas pocket valve then the opening of the bypass from channel 3 to channel 4.
  • the method according to the invention therefore offers a solution for optimum, dynamic adjustment of the engine operating state on the basis of energy changes which are present in channel 3.
  • a regulation and control of the boost pressure setpoint takes place via the gas pocket valve position.
  • the change in position of the gas pocket valve generates an energy pulse in the channel 3 of the pressure wave supercharger.
  • This energy change affects the cells of the cell rotor and thus the fresh air to be compressed or compressed.
  • the adjusting element is adjusted with a correction value as a function of the change in position of the gas pocket valve.
  • the relative value of the difference of the gas pocket valve position is evaluated as a controlled variable and a correction value is displayed as a relative value as a control signal.
  • the engine speed of the internal combustion engine is another important preferred input variable, the engine speed of the internal combustion engine.
  • a limitation of the current position of the control element is important. This is preferably determined within the scope of the invention by a map structure of actual boost pressure actual value and the engine speed of the internal combustion engine having a maximum value and a minimum value. Between the maximum value and the minimum value, an optimal position of the actuating element or a correction adjustment of the actuating element is determined on the basis of the difference between the gas pocket valve position and the engine speed of the internal combustion engine.
  • the inventive dynamic boost pressure control can take place either open-loop or closed-loop. Overall, this can be a significantly faster control behavior and thus response at at the same time achieve low hardware and software costs for control and regulation.
  • the relative adjustment of the gas pocket valve is the difference of the adjustment measured over time or the relative adjustment between actual value of the gas pocket valve and target value, which can be determined from a map.
  • the optimal position of the gas pocket valve is the optimal position for achieving the highest possible efficiency in the interaction of internal combustion engine and pressure wave loader.
  • the difference or the relative adjustment of the gas pocket valve in comparison to the determined or calculated optimum position is a value which shows how optimally the pressure wave process works.
  • the Retativwert can therefore be taken as a control variable for the optimization of the pressure wave process.
  • the control variable for relative adjustment of the gas pocket valve will go to zero and thus also the corrections for other control elements.
  • the control times for this control process are in the range of 5 to 10 ms.
  • a relative motor power is to be understood as the following definition.
  • the desired engine power is divided by the maximum possible engine power and multiplied by 100%. This then gives a relative motor power, which, expressed in percent, is detectable by the maximum possible engine power.
  • the relative engine power is always seen based on an engine speed. Based on a map that shows power over speed, the relative engine power is always seen in the vertical for a speed range. Since the control procedure is carried out dynamically, a specific speed value is first detected on the vertical, but due to the time-resolved control and regulation, the process can still be regarded as dynamic since a speed increase or decrease is taken into account by the time intervals of the control and regulation.
  • the relative load is the target load, which is determined for example by the accelerator pedal position divided by the maximum possible load of the respective speed times 100%.
  • an internal combustion engine torque structure is a strategy upon which an engine management control builds.
  • the entire control of the internal combustion engine is related to the torque in Nm.
  • the internal combustion engine torque structure can thus operate in Nm, but it can also operate on the basis of a relative load.
  • the respective internal combustion engine torque structure is manufacturer-specific depending on the control unit, which is installed on the internal combustion engine.
  • the supercharger speed of the cell rotor is adjusted and / or regulated as a function of the gas pocket valve position.
  • the supercharger speed is thus the speed of the pressure wave supercharger.
  • this is driven by its own engine, in particular electric motor, which is why the supercharger speed is arbitrarily variable adjustable.
  • the control of the supercharger speed of the cell rotor is combined with the adjustment of the position of the actuating element.
  • the supercharger speed is preferably limited.
  • the limitation can be determined as a function of the boost pressure actual value and the engine speed of the internal combustion engine.
  • a maximum value and a minimum value of the supercharger speed for limiting can be optionally determined.
  • the map structure determines the upper and lower limits and determines the correction values therebetween.
  • the thus determined value for a supercharger speed setpoint is thus output as a correction value to the supercharger speed control.
  • the FIG. 1 shows a portion of an internal combustion engine A in an embodiment shown here as gasoline engine.
  • the pressure wave supercharger B has four channels (1, 2, 3, 4) connected to these. These are the channel 1 (1) in the area of the intake fresh air, the channel 2 (2) in the region of the compressed fresh air for feeding to a charge air cooler J and an adjoining throttle valve K after which the compressed fresh air is supplied to the combustion chamber 10. Further, a passage 3 (3), which is disposed after the exhaust valve 6 and a catalyst in front of the pressure wave supercharger B, for introducing the exhaust gas into the supercharger B.

In the region of the exhaust line S, the pressure wave supercharger B, the channel 4 (4) for discharging the exhaust gas after the compression process in the pressure wave supercharger B. The channel 4 (4) also has an oxidation catalyst M.
  • a sectional view through the cylinder wherein an inlet valve 5, an outlet valve 6, a piston 7, a spark plug 8, a Injector 9 and a combustion chamber 10 is shown.
  • a pressure wave supercharger B is connected to the internal combustion engine A.
  • the pressure wave supercharger B furthermore has a cold gas housing side 11 and a hot gas housing side 12.
  • an actuating element D is arranged in the cold gas housing half 11.
  • the actuator D is controlled by a Steuerusionnstellmotor.
  • the arranged in the pressure wave supercharger B rotor C is driven by an electric rotor motor E.
  • the fresh air sucked in follows a path through the channel 1 (1) into the rotor cell 13 adjacent to the channel 1 (1) and is compressed in the pressure wave supercharger B.
  • the compressed air is then supplied to the inlet valve 5 via the channel 2 (2) in the outlet region of the channel 2 (2).
  • a recirculation valve with associated servomotor H in channel 2 (2) is interposed still arranged to bypass the intercooler and the combustion chamber 10 through a bypass line.
  • the charge air cooler J the compressed and heated air is cooled so that its volume decreases, which leads to a higher degree of cylinder filling in the combustion chamber 10.
  • the exhaust stroke the exhaust gas formed in the combustion chamber 10 through the channel 3 (3) the pressure wave supercharger B is fed back to the hot gas side.
  • a catalyst L is interposed, which carries out a first exhaust aftertreatment.
  • the gas pocket valve F driven via a gas pocket valve motor F increased entry of residual gas into the rotor cells 13 via the inlet opening of the channel 3 '(3') allows and / or exhaust past the rotor leads directly in channel 4 (4).
  • the pressure wave compresses the fresh air drawn in through the channel 1 and ensures that the compressed fresh air flows into the channel 2 (2) and is subsequently transferred into the exhaust gas line through the outlet opening of the rotor cells at the channel 4 (4).
  • the exhaust gas then flows through optionally further exhaust aftertreatment components, for example in the form of an oxidation catalyst M.
