Definitions
- the invention relates to a method and a device for controlling or controlling the compressor of an exhaust gas turbocharger of an internal combustion engine according to claim 1 or 8.
- an engine turbocharger control management system in which for controlling the compressor of the turbocharger, a pressure sensor is arranged directly at the inlet of the compressor. Another pressure sensor is provided directly at the outlet of the compressor in the compressor outlet line. Further, a speed sensor is provided which determines the compressor speed, for example by determining the speed of the turbocharger shaft.
- engine exhaust is partially returned to the compressor inlet line as part of the exhaust gas recirculation.
- upstream particle filter can not be prevented that particles and exhaust gas condensate get into the compressor inlet line, causing serious measurement problems.
- a pressure measurement directly at the compressor is a special effort, since the sensor may need to be placed in a difficult to reach place and must be suitable for the prevailing operating conditions there.
- the solution of this object is achieved by the features of claim 1 and claim 8.
- the actual compressor pressure ratio can be approximated with sufficient accuracy in a simple manner.
- the negative pressure in the compressor inlet line and, secondly, the pressure loss in the compressor outlet line can be determined by calculation as a result of the losses of the throttle flap and of the charge air cooler.
- the data necessary for the calculation of the compressor pressure ratio can be determined in advance specifically for the operating point.
- the ambient pressure preferably a near-ambient ambient pressure
- the static pressure of the ambient air instead of a negative pressure of a flowing gas mixture, which is technically much easier and less expensive. This results in a cost-effective, but sufficiently accurate control or control of the compressor in the manner previously explained.
- the pressure sensor can be attached to the control device or integrated into it, which simplifies the structure of the control system according to the invention.
- FIGURE of the drawing shows a schematically greatly simplified representation of a control system 1 according to the invention for explaining its structure and for explaining the method according to the invention.
- the control system 1 according to the invention of a compressor 2 of a turbocharger 3 for an internal combustion engine 4 initially has a control device 5, which can be designed in the usual way.
- a first pressure sensor 6 is arranged directly on the control unit 5 or integrated therein and serves to measure an ambient pressure Py, preferably a near ambient engine pressure, which is a static pressure of the ambient air. The measurement results in a signal S PU , which is fed to a calculation unit 21 of the control device 5.
- the control device 1 further comprises a second pressure sensor 7, which is arranged in front of an intake manifold 15 of the internal combustion engine 4, or, alternatively to the illustrated embodiment, may be arranged in the intake manifold 15.
- This pressure sensor 7 measures a second pressure P v , which represents the pressure of the compressed by the compressor 2 fluid before entering the internal combustion engine 4. That I resulting measurement signal S PV is also supplied to the control unit 5 via a corresponding signal line.
- a third sensor 8 is provided, which is a speed sensor for determining the compressor speed U.
- This speed sensor 8 may be either the speed of a shaft 9 connecting the compressor 2 to a turbine 10 of the turbocharger 3, or it may directly control the speed of the compressor wheel or turbine wheel (both not shown in the drawing) by using signals indicative of or by means of markings the blades are generated to be determined.
- the speed signal can also be used to protect the exhaust turbocharger against overspeeding.
- the turbine 10 of the turbocharger is connected to an exhaust duct 17 via the exhaust manifold 16 of the engine 4 to be rotated by the supplied engine exhaust gas, thereby driving the compressor wheel of the compressor 2, which however, represents a common construction that need not be further explained for the principles of the present invention.
- FIG. 19 shows a bypass line 19 with a bypass valve 20, which represent a way to control the compressor 2, which can also be carried out in the usual manner.
- control unit 5 supplied signals S U ( S PU and S PV the calculation unit 21 of the control unit 5 are evaluated and so the control of the compressor 2 performed according to the respective compressor map, so that the compressor 2 in an optimal operating range of this map can be operated.
- control strategy also corresponds to conventional principles, to which reference may be made, for example, to the initially described DE 10 2004 059 369 A1, the disclosure of which is hereby made explicit reference to the disclosure of the present application.
