Embodiment
Fig. 1 shows a kind of equipment for the burning in determination and analysis internal-combustion engine 1.Internal-combustion engine 1 has four cylinders 2,3,4,5 in this example, the piston that is not shown further, movement in cylinder 2,3,4,5 of described cylinder is connected with bent axle 10 respectively by connecting rod 6,7,8,9, further, described bent axle is driven by pressure caused between main combustion period change.Cylinder 2,3,4,5 is connected with suction tude 11, and described suction tude is closed relative to air intake pipe 13 by closure 12.In each cylinder 2,3,4,5, put in the nozzle for burner oil, form fuel-air mixture thus.In addition, each cylinder 2,3,4,5 has for the intake valve 15 of fresh air and the exhaust valve 16 for discharging the waste gas produced during combustion process, and described intake valve and exhaust valve only exemplarily illustrate for cylinder 5.In the firing chamber 22 of each cylinder 2,3,4,5, be furnished with pressure transducer 17, the detection of this pressure transducer is changed by the pressure caused by burning in the cylinder 2,3,4,5 of internal-combustion engine 1.The signal of pressure transducer 17 is transmitted to controller 18, described controller is also connected with a CKP 19, CKP 19 is opposite with bent axle 10, wherein, burning is mapped with the corner signal of CKP 19 by controller 18, and CKP 19 is preferably designed to speed probe.At this, controller 18 comprises microprocessor 20, and described microprocessor is connected with storage 21.
Based on the crank angle determined by CKP 19, the rotating speed of internal-combustion engine 1 can also be determined by controller 18, especially microprocessor 20 simultaneously.
In the storage 21 of controller 18, store the firing angle efficiency characteristic ETADZW of firing angle efficiency of representative about the deviation of the firing angle preset and optimal ignition angle, this firing angle efficiency characteristic illustrates the function between the optimal ignition angle of internal-combustion engine 1 and default actual ignition angle.At this, optimal ignition angle is determined by the FAI Fresh Air Intake of the firing chamber 22 of cylinder 2,3,4,5 and the rotating speed of internal-combustion engine 1.
In order to firing angle efficiency characteristic can be adjusted for each internal-combustion engine 1 and make the service time of itself and internal-combustion engine 1 suitable, propose two kinds of methods.According to Fig. 2, the adaptation of firing angle efficiency characteristic is carried out on all cylinders 2,3,4,5 by the torque reserve improving internal-combustion engine 1 step by step simultaneously.At this, in step 100, carry out reference measurement, do not require any torque reserve when reference measurement.In the reference measurement of this firing angle efficiency, benchmark firing angle efficiency is determined by optimal ignition angle and the actual ignition angle of presetting and is saved (step 110).In next step 120, require that the first time of torque reserve improves (n=1).At this, measure the middle pressure pmi (step 130) of instruction, described middle pressure is exported to controller 18 by pressure transducer 17 as pressure signal and analyzed as the parameter for combustion process in the microprocessor 20 of controller 18.The firing angle efficiency pushing away current by the middle pressure pmi of this instruction, compares this current firing angle efficiency and benchmark firing angle efficiency in step 140.If there are differences between this benchmark firing angle efficiency and determined firing angle efficiency, so in step 150, consider this difference when carrying out adaptation to firing angle efficiency characteristic and in characteristic curve ETADZW, adjust a new firing angle efficiency.Then, in a step 160, torque reserve is improved identical amount, wherein, check the maximum value whether current adjusted torque requires corresponding to torque reserve in step 170.If not maximum value, so again determined firing angle efficiency and benchmark firing angle efficiency under the requirement of current torque reserve are compared (step 140).Repeatedly perform step 130 to 170, until reach the maximum value of torque reserve requirement in step 170 always.If reach the maximum value of torque reserve requirement, then in step 180, terminate this adaptive flow process.
But, in above-mentioned adaptive flow process, not the signal that must use described pressure transducer 17.When not having pressure transducer 17, can be dependent on by the known so-called machine work feature (MWF) of DE10 2,008 054 690 A1, in the publication, come for the cylinder preset of internal-combustion engine calculates firing angle efficiency according to current tach signal, the tach signal that especially drawn by each gear teeth time of the sensor wheel of the bent axle of internal-combustion engine.Described tach signal comprises and the information of difference correlation of the physical energy that transforms between main combustion period or merit, and the characteristic of described energy or merit is as by the chamber pressure pmi measured by pressure transducer 17.For this reason, before the burning in associated cylinder and before burning by described tach signal calculate on time point that bent axle 10 selects in correspondence in other words at the energy of the crank angle preset, and determine described difference thus.Described difference represents the amount of physical energy or the merit transformed by the burning of correspondence.
This flow process is used in the second embodiment of the adaptive flow process for adjusting firing angle efficiency characteristic adaptedly according to the present invention, this flow process is undertaken by the delay of the firing angle step by step adjustment of the cylinder 2,3,4,5 of internal-combustion engine 1, as shown in Figure 3.In step 200, reference measurement is carried out.At this, described benchmark firing angle efficiency is determined as the difference between optimal ignition angle and actual ignition angle under the condition adjusted without firing angle.In step 210, this benchmark firing angle efficiency is saved.Then, in a step 220, to the side postponed, one firing angle preset is adjusted upward firing angle for the cylinder 2,3,4,5 that will check.At this, the endurance of measurement can carry out in the work cycle of the predetermined number of cylinder 2,3,4,5.At this, by determined actual ignition angle and optimal ignition angle determine current, postpone to adjust corresponding firing angle efficiency (step 230) with the firing angle through regulating.In next step 240, current determined firing angle efficiency and the benchmark firing angle efficiency be saved in step 210 are compared.If there are differences between benchmark firing angle efficiency and current firing angle efficiency, so in step 250 this difference is used for adaptive firing angle efficiency characteristic.If benchmark firing angle efficiency is consistent with current measured firing angle efficiency, terminate this flow process so in step 260.
If carried out the adaptation of firing angle efficiency in step 250, continue firing angle to retarding direction adjustment so in step 270, adjustment amount has been the firing angle used, and determine in step 230 current, corresponding to the firing angle efficiency of this firing angle.At this, step 230 can repeatedly be carried out in succession to 270, thus adjusts the maximum adaptation of firing angle efficiency in step 250.At this, firing angle always adjusts identical igniting angular amount to retarding direction respectively.
Each cylinder 2,3,4,5 for internal-combustion engine 1 carries out the flow process described in composition graphs 3 continuously.Then, when the characteristic curve ETADZW be adapted is by postponing to adjust by each firing angle, on all four cylinders 2,3,4,5, determined firing angle efficiency is averaged and is determined.When each cylinder 2,3,4,5 exists obvious deviation, this can be used for the diagnosis of such as spark plug.
Fig. 4 shows the situation of the firing angle efficiency when firing angle postpones adjustment, and wherein, firing angle efficiency is determined by machine work feature (MWF), and machine work feature illustrates about indicated middle pressure PMI.Arrow P at this illustrate firing angle to the adjustment of retarding direction.Clear thus, the side that firing angle is postponing adjusts upward more, and energy handled in cylinder 2,3,4,5 is less.
Fig. 5 shows the characteristic curve calculated by above-mentioned measurement.At this, about at the firing angle preset and without the deviation between the firing angle postponing to adjust, show pressure p mi machine work feature MWF in other words.This characteristic curve is mirror image reversal relative to the characteristic curve of firing angle efficiency.It can be converted into characteristic curve ETADZW simply.
For above-mentioned two kinds of methods, adaptive frequency can be carried out according to the distance travelled of internal-combustion engine 1 and/or service time and/or the index that may be present in engine control system.
