Definitions
- the invention is based on a method or of a device for controlling the volume flow in one Common rail injection system of an internal combustion engine according to the independent claims 1 and 8. It is already known that in injection systems where the fuel injected directly into a cylinder of an internal combustion engine is, the rail pressure by Abêtung in the high pressure area is controlled by a pressure control valve. The load point dependent Volume flow, however, is a flow control valve controlled. The controller is designed in this way that the high pressure pump as possible only the current Need for fuel supplies. With this approach should be achieved, on the one hand the power consumption of High pressure pump is kept low. On the other hand, too the fuel return amount and thereby in the low pressure range introduced amount of heat minimized.
- To control the flow control valve is a two-dimensional Pre-control map used that of the injection quantity and the engine speed is performed.
- the injection quantity and the engine speed are a measure for the current volume flow requirement of a particular Load for the internal combustion engine corresponds. Due to component variations it is additionally required a map with adaptation values for the control of the volume flow control valve provided. In particular, since the volume flow demand due to wear-induced higher internal leaks increase the lifetime of the system. The previously used Adaption map is only dependent on the rail pressure. Thus, in addition to the pilot control map, the one-dimensional Adaptation map for controlling the volume flow control valve used.
- pilot control map (eg due to wear-related higher volume flow requirement) too low values, is due the behavior of the rail pressure regulator (high positive control deviation, since the amount to maintain the pressure is not sufficient) an adaptation of the volume flow control valve driving value triggered until the amount is sufficient again.
- This adaptation value has hitherto been dependent on the rail pressure stored and at every load point that with this Pressure is used, used.
- the flow control valve is thus always with the pre-control value plus the adaptation value controlled.
- the invention is based on the object, the control of the Volume flow control valve to improve so that only possible the required amount of fuel is provided.
- adaptation values are stored in an adaptation map, this is the adaptation value as a function of the two operating parameters Engine speed and injection quantity reflects. Because with these two operating parameters can be a one-to-one Adaptation value for the flow control valve pretend.
- a linear interpolation of the adaptation values performed using the known algorithms can be.
- the values become the adoption map during operation of the injection system customized.
- the values of the Adaptation map changed when the control variable of the controller the pressure regulating valve over a fixed threshold or below.
- the device is advantageously in a diesel, Gasoline or gas engine applicable.
- Figure 1 is a schematic representation substantially the high pressure part of a common rail injection system shown, that for an internal combustion engine, for example a Diesel, gasoline or gas engine is usable. It shows the Components with which the fuel in the rail under high Pressure for the injectors is provided.
- an internal combustion engine for example a Diesel, gasoline or gas engine is usable. It shows the Components with which the fuel in the rail under high Pressure for the injectors is provided.
- the fuel is first of a (not shown in Figure 1 Tank) via a fuel inlet A of a fuel priming pump 1 supplied.
- the fuel feed pump 1 is above its output with the input of a controllable Volume flow control valve VCV connected.
- VCV controllable Volume flow control valve
- a form control valve 5 over the excess fuel be returned to the low pressure area can.
- the output of the flow control valve VCV connected to a high-pressure pump 8, which in the rail a very high fuel pressure, depending on the application, for example 800 ... 2000 bar generated.
- the high-pressure pump 8 three displacement units 3 on.
- a flushing / lubricating valve 6 is installed over which the Fuel feed pump 1, the high-pressure pump 8 with fuel rinses and lubricates.
- a high pressure control valve PCV At the high pressure outlet of the high pressure pump 8 is a high pressure control valve PCV arranged.
- the high pressure control valve PCV regulates preferably by means of a PI controller, the high fuel pressure in the rail.
- the high-pressure control valve PCV on Split filter 7 downstream to solid suspended particles in To filter out fuel before the fuel is over High pressure connection B to a downstream fuel storage supplied with connected injectors.
- a branch for a fuel return C provided to excess Fuel returned to the low pressure area.
- FIG. 2 shows a known two-dimensional pilot control map, that for controlling the volume flow control valve VCV use place.
- the pilot control value for the flow control valve VCV is then for a current speed N and a load-dependent predetermined Injection quantity MF on the Z-axis as percentage (% value) the pulse width modulated signal with which the flow control valve is controlled, readable.
- the pilot control value initially serves for the volume flow control valve VCV as a default value, which is still using an adaptation value can be adjusted to depend on the actual Parameters of the injection system an exact valve position to obtain.
- pilot value can also be stored as a table be.
- table are also dependent on the Engine speed N and the injection quantity MF, the characteristics as Percentage values from the maximum opening angle of the flow control valve VCV indicated.
- the valve position of the volume flow control valve VCV is with Help of a pulse width modulation (PWM values) controlled.
- PWM values pulse width modulation
- Around to achieve an adaptation of the valve position is used to determine of the PWM value for a current operating point Adaptation value from the adaptation map to the pilot control value of the pilot control map.
- the adaptation map in Dependence of two operating parameters two-dimensional form.
- FIG. 3 shows an exemplary embodiment of the invention Adaptation characteristic field.
- the adaptation map owns - in this special case - the Same axes as the pilot control map of Figure 2.
- On the X-axis is the speed N and the Y-axis is the injection quantity MF applied.
- the adaptation value A can then open the Z axis as a percentage of the maximum opening angle of the Volume flow control valve VCV are read.
- the adaptation values in the adaptation map depend on each of two of the following operating parameters filed are: the injection quantity MF, the engine torque, the engine speed N and / or the load TQI.
- the values of the adaptation map are preferably be linearly interpolated. This can be done with a simple linear regression also determine intermediate values, so that the adaptation values are determined more accurately.
- the adaptation values for the individual load points in the two-dimensional adaptation map be continuously adjusted so that an automatic adaptation for the flow control valve VCV yields. This results in an exact load point-dependent Adaptation to the toleranced components installed, which is also independent of their aging and wear works.
- the controlled variable of the PI regulator of the pressure regulating valve of one Control unit monitored. Exceeds the controlled variable of the PI controller a set threshold, so will from the control unit a corresponding adaptation value in the adaptation map to the present operating point according to the parameters entered the axis of the adaptation map. He adaptation value is chosen so that when controlling the volume flow control valve VCV with the pilot value from the pilot control map and the adaptation value from the adaptation map so much fuel in the fuel tank is that the control variable of the PI controller again below the Threshold arrives.
- the adaptation value is for example at Exceeding or falling below the threshold for the controller value by a fixed value or a specified one Percentage reduced or increased.
- Figure 4 shows an embodiment of the invention with a Device for controlling the load point-dependent volume flow in a common rail injection system. It has one program-controlled control unit 10, which with a program memory 11, a memory 12 for a first pilot control map for the pressure control valve and a second pilot control map for the flow control valve and with a memory 13 is connected to an adaptation map.
- the control unit 10 a program is running, which the connected Components fuel feed pump 1, high pressure pump 8, High pressure control valve PCV and the volume flow control valve VCV etc. regulates or controls.
- a PI controller 9 the high-pressure control valve PCV after the predetermined first pilot control map regulates.
- the PI controller 9 connected to the controller 10 and reports the current Control value of the high-pressure control valve to the control unit 10.
- the controller 10 is connected to sensors that the operating parameters, in particular the rotational speed, the injection quantity, detect the engine torque and the load.
- the Volume flow control valve VCV is in its valve position by means of the second pilot control map and the two-dimensional map Adaptionskennfeldes controlled so that every current Last point as exactly as possible the required amount of fuel provided. Through this load point-dependent Control of the volume flow control valve VCV is in an advantageous Way that minimizes the fuel return amount and thus in particular a heating of the fuel in the Tank is avoided. Furthermore, it is achieved that the High pressure pump with a timing belt or a mechanical Clutch is driven, consumes less energy and thus reduces the power consumption of the high-pressure pump. The result is a high engine performance and / or a reduced Fuel consumption.
