Definitions
- the invention relates to an annealing and Ionenstrommeßvoriques for a diesel engine with one for each or individual cylinders of the diesel engine respectively provided Annealing and Ionenstrommeßkerze, in the annealing operation a Annealing voltage and in measuring mode is a measuring voltage, the lower than the annealing voltage.
- the glow operation of a glow plug is used in a diesel engine in addition, the ignition, for example, during cold start or assist by intermediate annealing. By measuring the ionic current is beyond a determination of the combustion conditions possible in the cylinders of the diesel engine.
- the glow plugs in particular so energized that they are at a temperature of more than 800 ° C support the ignition. In parallel then will the ion current measured in the cold start z.
- the object underlying the invention is Therefore, therein, an annealing and Ionenstrommeßvorraum the to create the aforementioned type, in which the Glühund the measuring functions do not interfere with each other.
- the annealing of an incandescent and Ionenstrommeßkerze is interrupted for a certain time, in order to be able to measure the ion current during this time, the at the Glüh- and Ionenstrommeßkerze lying RMS voltage from.
- the effective Voltage by 8.7% and thus the glow power around 16.7%.
- the glow plug is thus in the regulated state to a lower temperature so that they do their job as Ignition support can only meet insufficient. at a two-stroke engine affects the double because of the frequent working cycles even clearer.
- the synchronization of the switching operations with the motor and Drive clocks may be through communication with the Engine control unit or by a suitable separate control be ensured. It does not have every stroke be madeftstert, the measurement can easily also only for the second, third and fourth working cycle respectively. The glow and Ionenstrommeßkerze is then adapted accordingly.
- crankshaft angle of 700 ° corresponds to the crankshaft angle of -20 °, so that the illustrated in Figure 1 Repeat the operations periodically.
- an annealing control device which the available vehicle electrical system voltage periodically on and turns off, d. H. the annealing and Ionenstrommeßschreiben in Form of voltage pulses timed across extend a portion of the crankshaft angle.
- the incandescent and Ionenstrommeßkerze is designed so that their nominal tension, at which they have the required Temperatures reached only a fraction of the available standing mains voltage. In wiring systems with 14 Volts, this nominal voltage is about 4 to 9 volts.
- the timing by the Glüh horrinvoriques is with synchronized to the firing times of each cylinder, that the break in the energization for the Glüh plante for example with the expected time of ignition or combustion begins at which the ionic current can occur.
- the measuring voltage is applied to the glow and Ionenstrommeßkerze, which is much lower than the annealing voltage is, so that during this time the Glüh- and Ionenstrommeßkerze as an electrode or sensor for measuring the ion current is working.
- the timing is preferably such that the energization the individual incandescent and Ionenstrommeßkerzen for the Cylinder is made so that it is analogous to the ignition of the cylinder is turned on one after the other, reducing the current load of the electrical system is made uniform.
- the timing is, however such that the Glühenciesimpulse and the Measuring voltage pulses of the incandescent and Ionenstrommeßkerzen of two different cylinders, for example the glow voltage pulse 10 for the glow and Ionenstrommeßkerze the fourth cylinder with the measuring voltage pulse 9 for the Glühund Ion current plug of the first cylinder overlap.
- the annealing voltage and measuring voltage pulses applied to the Glühund Ionenstrommeßkerzen the individual cylinders are each in addition extend over about 280 ° of the crankshaft angle.
- glow and Ionenstrommeßvoriquesen can ion current signals at the same time full Functioning of the annealing operation, for example as Cold start aid to be measured. This is a mode of operation possible, at the expected ignition timing the highest possible Temperature at the glow and Ionenstrommeßkerze to Available.
