Definitions
- the invention relates to a method for adjusting a volumetric flow variable displacement pump in one Internal combustion engine.
- Such displacement pumps are used in internal combustion engines primarily as lubricant pumps for oil lubrication used (e.g.; US-A-5 800 131). It is known that the adjustment of such Positive displacement pumps either mechanical, hydraulic, mechanical-hydraulic or electro-hydraulic. Under the adjustment of a volume flow variable A positive displacement pump is understood to be reducing or enlarging of their displacement space. This is done at a volumetric flow variable vane pump the axis offset of the rotating rotor to the middle of the pump so changed that individuals between the wings Displacement rooms can be enlarged or reduced. The Changing the axis offset is called adjustment. The Pump adjustment is done when either the system pressure should be varied or the flow rate needs to be adjusted.
- the invention has for its object a method provide with which a volume flow variable Displacement pump optimally to a changing needs Internal combustion engine can be adjusted.
- a distinctive characteristic value of the internal combustion engine is determined 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 target value.
- the suction pressure (p S ), the delivery pressure (p L ), 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 as a characteristic value. This means that there is also the possibility that several different characteristic values are determined and the positive displacement pump is controlled depending on these several characteristic values. The several characteristic values can be queried simultaneously or one after the other.
- the setpoint 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 e.g. B. a deviation of 5% from the setpoint leads to an adjustment of the positive displacement pump, whereas deviations below this limit value are irrelevant.
- Another variant provides that a change in the Volume flow is only made when the control signal changes by a certain amount. This can also 5% or 10%.
- the control unit that is already present can advantageously be used Engine control computer can be used, in which already one Variety of key data can be processed.
- the engine control computer then only has to use the data from the Displacement pump and the calculation rules for the Setpoint / actual value comparison and for signal generation can be added. So there is no need for additional sensors even more lines, so that the component expense is relatively small.
- the actuator is preferred against a restoring force actuated.
- the displacement volume of the positive displacement pump reduced. This has the main advantage that at Failure of the control chain or a single component Displacement pump via the return spring, which the Displacement pump returns to the starting position maximum volume flow is adjusted.
- Reference number 1 denotes a positive displacement pump, which is driven by an internal combustion engine 2.
- the Displacement pump 1 sucks the oil from an oil sump 3 and promotes this to a variety of lubrication points 4 in the internal combustion engine 2, of which only one is shown.
- the oil runs from the lubrication points 4 back into the oil sump 3.
- the method according to the invention uses the measuring points 5 present in the engine system to determine the delivery pressure p L , the delivery quantity Q, the temperature T, the suction pressure p S and the speed n as actual value signals for processing in a control unit 6.
- the sensors already present and laid cables used.
- the existing engine control computer is used and supplemented if necessary.
- target data for the measuring points 5 for the respective operating state of the engine are stored for the working area of the engine 2.
- the actual value signals determined at the measuring points 5 are compared in the control unit 6 with the target data stored there. From the deviations between the actual values and the target values, an actuating signal is generated in the control unit 6, which is forwarded to an actuator 8 via a signal transmitter 7.
- the actuator 8 uses the control signal to increase or decrease the displacement space of the displacement pump 1 until the actual value signals at the measuring points 5 match the setpoint signals in the control unit 6. Suitable control systems are used for this.
- measuring points 5 can be used that however, fewer measuring points 5 or additional additional Measuring points 5 can be used.
- the control unit 6 can be available as a single device or it is, as already mentioned, integrated in the engine control computer. In this case only need additional data for the positive displacement pump 1 as well as the calculation rules for the setpoint / actual value comparison and the signal control generation is stored become.
- the signal generator 7 can also be used as a single device be formed or it is in the control unit 6 or in the Actuator 8 integrated.
- the actuator 8 is designed as a discrete component or is already integrated in the positive displacement pump 1.
- the Actuator 8 contains one of the adjustment direction counteracting return spring 9, which is used to Failure of the measuring points 5, the control unit 6, the Signal generator 7 and the actuator 8 formed control chain or a single component thereof, the adjustment of the Displacement pump 1 to the largest chamber volume guarantee. Malfunctions or an undersupply of the Internal combustion engine 1 with lubricant avoided.
