Definitions
- the invention relates to a method for adjusting a volume flow variable positive displacement pump in an internal combustion engine.
- Such positive displacement pumps are used in internal combustion engines primarily as a lubricant pump for oil lubrication. It is known that the displacement of such displacement pumps takes place either mechanically, hydraulically, mechanically hydraulically or electro-hydraulically.
- the adjustment of a volumetric flow variable displacement pump is understood to mean the reduction or enlargement of its displacement space.
- a volumetric flow variable vane pump the axial offset of the rotating rotor is changed to the pump center in such a way that the individual displacement spaces located between the wings are increased or decreased. Changing the axial offset is called adjustment.
- the adjustment of a pump is then carried out when either the system pressure to be varied or the flow rate must be adjusted.
- the invention has for its object to provide a method by which a volume flow variable positive displacement pump can be optimally adapted to changing needs of an internal combustion engine.
- a distinctive characteristic value is determined from the exhaust gas flow of the internal combustion engine and, depending on the deviation of this characteristic value from an actual value signal, the displacement pump is adjusted until the characteristic value is adjusted to the desired value.
- a signal of a lambda probe located in the exhaust gas flow is used in a preferred embodiment.
- the suction pressure (ps), the delivery pressure (PL), the speed (n) of the internal combustion engine and / or the positive displacement pump, the temperature (T) of the fluid and / or the delivery rate (Q) of the fluid can be determined.
- the positive displacement pump is controlled.
- the multiple characteristic values can be queried simultaneously or one after the other. In any case, however, the parameter from the exhaust gas flow is used for control.
- the desired value can be made available in the form of setpoint ranges so that only a deviation of a certain order of magnitude leads to an adjustment of the positive displacement pump.
- This can be set so that z. B. a deviation of 5% from the setpoint leads to an adjustment of the positive displacement pump, whereas deviations remain below this limit irrelevant.
- Another variant provides that a change in the volume flow is only made when the control signal changes by a certain value. These can also be 5% or 10%.
- the already existing engine control computer can be used as a control unit in which a large number of characteristic data is already being processed.
- the engine control computer then only has to be supplemented with the data of the positive displacement pump as well as the calculation rules for setpoint / actual value comparison and for signal generation.
- it requires neither additional sensors nor additional lines, so that the component cost is relatively low.
- an electromotive or hydraulic drive is used as the actuator.
- the hydraulic drive for both actuating directions can be acted upon with a fluid.
- the fluid used may preferably be the lubricating oil of the internal combustion engine.
- the displacement of the positive displacement pump is linear, progressive or degressive changed. In this case, the delivery volume of the positive displacement pump is increased or decreased. This has the significant advantage that rapid changes can be made in both directions.
- the positive displacement pump may be an oil pump or a gas pump, in particular a supercharger, preferably a hydrostatic or hydrodynamic supercharger.
- Reference numeral 1 denotes a positive-displacement pump, in particular a supercharger, which is driven by an internal combustion engine 2.
- the positive displacement pump 1 sucks e.g. Ol from an oil sump and calls this to a variety of lubrication points in the internal combustion engine 2, of which only one is shown.
- the oil runs from the lubricant points back into the oil sump.
- this air aspirates from the environment 3 and calls it over the intake tract of the internal combustion engine 2 m the combustion chambers 4. From there the exhaust gas enters an exhaust system 8 and from there into the environment 3.
- the exhaust system 8 is a Lambda probe 9, which provides characteristics that are processed in an engine control unit to optimize gas mixing.
- the erfmdungsgedorfe method additionally uses the characteristics of existing in the engine system measuring points 5 to determine delivery pressure p L , the Q, the temperature T, the suction pressure ps and the rotational speed n as actual signals for processing in a control unit 6.
- the already existing Sensors and installed cables used.
- the existing engine control unit is used and supplemented if necessary.
- Setpoint data for the lambda probe 9 and the measuring points 5 for the respective operating state of the internal combustion engine 2 are stored in the control unit 6 for the operating range of the internal combustion engine 2.
- the actual value signals determined via the lambda probe 9 and at the measuring points 5 are compared in the control unit 6 with the desired data stored there.
- a control signal is generated in the control unit 6, which is forwarded via a signal generator 7 to an actuator 10.
- the actuator 10 is based on the control signal zoom in or zoom out the Verdrangerraumes the positive displacement pump 1 causes until the actual value signals of the lambda probe 9 and optionally at the measuring points 5 with the setpoint signals in the control unit 6 match.
- suitable control systems are used.
- the control unit 6 may be present as a single device or it is, as already mentioned, integrated in the engine control unit. In this case, only additional data for the positive displacement pump 1 and the calculation rules for the setpoint / actual value comparison and the signal control generation need to be stored.
- the signal generator 7 may also be designed as a single unit or it is integrated into the control unit 6 or m the actuator 10.
- the actuator 10 is formed as a discrete component or is already integrated in the positive displacement pump 1.
- the actuator 10 includes a solenoid valve 11 and a hydraulic drive 12 with a m both actuating directions driven piston.
- the hydraulic drive 12 is supplied via a separate pump 13 or via the lubricant circuit of the internal combustion engine 1 with pressure medium.
