- a Internal combustion engine for example a diesel engine
- DE 197 49 815 A1 describes an engine management system for an internal combustion engine known, by detecting the combustion chamber pressure in each cylinder or combustion chamber of the internal combustion engine depending on the crank angle in each Engine torque indexed combustion chamber determined and for the torque control of the Motor vehicle is used.
- characteristic maps are used for this filed, which motor torque data required for torque control include. By accessing these maps, depending on the appropriate settings detected or ascertained indicated appropriate engine torque
- Operating parameters of the internal combustion engine e.g. the amount of fuel injected, or the ignition timing, etc., for the best possible torque control of the Internal combustion engine are made.
- the present invention is therefore based on the object of a method and a To propose a device for regulating an internal combustion engine, the effective Engine torque can be taken into account.
- the method or the device according to the invention preferably also a determination of Torque loss by which the effective motor torque differs from that in the Internal combustion engine by combustion indicated engine torque, enable.
- the determination is used to effectively control an internal combustion engine the effective engine torque occurring on the crankshaft of the internal combustion engine proposed.
- the one occurring in a combustion chamber of the internal combustion engine Combustion chamber pressure as a function of the crank angle recorded and the indexed from it
- Engine torque derived in the combustion chamber From the indicated engine torque and the The angular velocity of the crankshaft can then be derived from the effective engine torque be, in particular the torque loss of the internal combustion engine can be determined and used for diagnostic purposes.
- An indexed medium pressure value can also be used as an intermediate variable from the combustion chamber pressure data derived and for controlling the internal combustion engine, for example to improve the Idling.
- the invention enables combustion chamber-based control loops and a combustion chamber-based one Engine management.
- crankshaft 4 of the internal combustion engine 1st driven is a crankshaft 4 of the internal combustion engine 1st driven.
- the internal combustion engine with four Clocking works reach the crankshaft 4 and the piston 3 within one Working cycle exactly twice the so-called top dead center OT and the bottom one Dead center UT, which corresponds to two complete revolutions of the crankshaft 4.
- the rotation angle ⁇ of the crankshaft 4 in degrees crank angle (° KW) specified.
- the pressure sensor 5 comprises, for example Measuring membrane, which depends on what is in the combustion chamber Combustion chamber pressure is expanded or deformed differently, the extent of Elongation or deformation of this measuring membrane as a measure of that in the combustion chamber 2 the prevailing combustion chamber pressure is evaluated by a control unit 7.
- the combustion chamber pressure prevailing in this way in the combustion chamber 2 becomes the current position of the crankshaft 4, d. H. to the current angle of rotation ⁇ the Crankshaft 4, related.
- a crankshaft sensor 6 provided, which continuously detects the current position of the crankshaft 4 and this supplies the control unit 7. In this way, the control unit 7 can follow the course of the Determine the combustion chamber pressure as a function of the angle of rotation ⁇ of the crankshaft 4.
- dQ W describes the wall heat energy extracted from the system
- dQ B describes the converted fuel energy or the combustion process of the injected fuel
- dH E is the enthalpy change of the mass flowing into the system
- dH A the enthalpy change of the outflowing mass
- dH B the enthalpy change of the injected fuel
- Equation (11) is the basis for the energetic assessment of the processes taking place in a combustion chamber 2 of the internal combustion engine 1.
- the effective specific work resulting from a combustion can be taken from the crankshaft 4 of the internal combustion engine 1 and expressed in the form of the effective mean pressure p me , the effective engine torque M e or the effective power P e .
- This effective specific work corresponds to the difference between the specific internal work, expressed by the indicated mean pressure p mi , the indicated engine torque M i or the indicated power P i , and the specific mechanical loss work (loss or friction mean pressure p mv , loss torque M v , Power loss P v ).
- the indicated mean pressure p mi thus corresponds to the volume change work related to the respective stroke volume V h .
- the indicated work corresponds to the area enclosed by the characteristic curve in the respective pV diagram. In four-stroke engines, it is divided into a high-pressure and a gas exchange component.
- the indicated mean pressure p mi_HD of the high pressure phase can be used as a parameter for the combustion of the individual combustion chambers and is defined between the two bottom dead centers UT of the crank path as a function of the measured combustion chamber pressure p as follows:
- the indicated medium pressure p mi_HD of the high pressure phase is preferably selected for the regulation and control of the internal combustion engine 1, since it physically describes the internal work of each combustion chamber 2.
- the torque M of the internal combustion engine 1 is proportional to the mean pressure (averaged between the individual combustion chambers or cylinders 2) p m of the internal combustion engine: (18) M ⁇ V H ⁇ p m ,
- the indexed engine torque is a conversion of the indexed work into a (virtual) moment (see equation (18) with the index i).
- the current indicated engine torque can be calculated from the continuous observation of the indicated work according to equation (19) by superimposing the curves of all z combustion chambers:
- the indicated engine torque is linked to the engine speed via a differential equation of the crank mechanism described in, for example, "Calculation of the combustion chamber pressure curve from crankshaft angular velocity of internal combustion engines", Fehrenbach H., progress reports VDI series 6, energy generation No. 255, VDI publishing house Düsseldorf, 1991, in this regard, reference is expressly made to the statements in this publication.
- the (momentary) indicated engine torque can be derived from the combustion chamber pressure with a resolution of 1 ° KW.
- the crankshaft angular velocity is also available with a temporal resolution of 1 ° KW.
- the loss torque M v (together) relates to the negative work due to friction losses on the respective piston and crank mechanism, as well as torque losses due to consumers of the respective motor vehicle also driven by the crankshaft, such as the air conditioning compressor, the injection pumps and the servo pump , the alternator etc., back.
- the following relationship applies between the individual moments: (22) M e ( ⁇ ) M i ( ⁇ ) + M v ( ⁇ ) ⁇ M v ( ⁇ ) ⁇ 0th
- the loss torque can be determined in this operating state from the above relationships and as a function of the indicated engine torque derived from the combustion chamber pressure.
- the drag torque can be determined from equation (18) from the drag medium pressure p ms .
- the existing control loops of the engine management system can be improved, since this additional information flows into the control or regulation of the internal combustion engine can.
- Certain manipulated variables for example the fuel injection quantity, the start of fuel delivery or the fuel injection curve, can be changed, for example in the form of a cylinder-specific combustion start or torque control, in such a way that the parameters extracted from the combustion chamber pressure are achieved. In particular, regulation takes place on the basis of the combustion actually taking place in the respective combustion chamber.
