- booster mode high booster voltages are specified to ensure short switching times.
- Homogeneous operation largely corresponds to operation a conventional spark ignition internal combustion engine.
- the fuel is operated at increased pressure in shifts injected, resulting in a non-homogeneous Distribution of the fuel concentration in the combustion chamber.
- the start and duration of the injection have a large one Influence on combustion.
- the injection is often in divided several partial injections.
- the voltage at the booster capacitor in homogeneous operation lowered by switching to thereby the to reduce the maximum power loss of the power amplifier. in the Shift operation increases the booster voltage again to achieve the required short injection times.
- FIG. 4b A further embodiment is shown in Figure 4b.
- the setpoint specification 300 gives the Booster voltage U1 as function F of an operating parameter H in front.
- the booster voltage U1 is preferably made up of one Map dependent on various operating parameters read. It is particularly advantageous if the Booster voltage depending on one or more of the sizes Engine speed, engine torque, duration of the Control, fuel pressure, temperature, supply voltage can be specified.
- the subsequent query 235 checks whether the Voltage UC applied to the booster capacitor is greater than is the threshold U1. If this is not the case, then in Step 236 the capacitor continues charging. Recognize that Query 235 that the voltage UC at the booster capacitor is greater than the threshold value U1, step 240 takes place the injection, the switching means being given to the Times t1 to t5 can be controlled.
- the operating parameters in step 330 are the speed and / or the injection duration are taken into account.
- the value can also be predetermined as a function thereof be whether the internal combustion engine in the homogeneous or in Shift operation is located.
- This procedure is particularly advantageous if the Time intervals between two injections and / or between two partial injections of one injection in certain Accept operating states of very small values.
- Such Operating conditions are, for example, at high speed when switching to homogeneous operation after stratified Operation and with double and multiple injections before. In these conditions is for charging the booster capacitor to the defined voltage value Minimum interval between two injections required. This time should be measured so that the used DC-DC / converter even under the worst Conditions the booster capacitor to the defined one Voltage value can charge.
- the Booster voltage can be the time interval for charging be shortened when the charging time to the maximum value the booster voltage in these operating states no longer is to be observed.
- the booster voltage depends on the operating state. This means shorter charging times and therefore shorter Intervals between two injections reached.
- the Voltage values of the booster capacitor are here Are defined. The one from the lower booster voltage resulting slower turn-on times and thus lower injection quantities can be corrected by Injection time and / or the advance angle in step 242 can be corrected.
- FIG. 4c Another advantageous embodiment is shown in FIG. 4c shown.
- the Booster voltage immediately before using an AD converter Start of injection measured.
- it becomes possible predetermined time interval between two injection the is necessary to achieve optimal combustion, observed.
- step 250 it is checked in step 250 whether an injection just before. If this is not the case, one checks Query 255 whether the booster voltage UC is greater than one predetermined threshold value U1. If this is not the case, then is further loaded in step 260. If query 250 detects that an injection is imminent and / or query 255 recognizes that the booster voltage UC is greater than the setpoint, the current one in step 265 Booster voltage detected. In the subsequent step 270 the control times depend on the measured Booster voltage UC corrected.
- step 275 the control of the Solenoid valve.
