Die Anforderungen an eine moderne Brennkraftmaschine im Hinblick auf eine Reduktion des verbrauchten Kraftstoffs und der ausgestoßenen Abgase werden immer höher. Aus diesem Grund ist es erforderlich, die Zumessung des Kraftstoff in den Brennraum der Brennkraftmaschine weiter zu verbessern, insbesondere die zuzumessende Kraftstoffmasse noch genauer zu ermitteln. Zu diesem Zweck wird bei bekannten Brennkraftmaschinen nicht nur die Winkelstellung der Drosselklappe mittels eines Winkelsensors, sondern auch der Druck in dem Ansaugrohr nach der Drosselklappe mit Hilfe eine Drucksensors bestimmt. Diese Winkelstellung sowie dieser Druck nach der Drosselklappe werden dann dazu verwendet, die zugehörige einzuspritzende Kraftstoffmasse zu berechnen, die erforderlich ist, um einen von dem Fahrer des Kraftfahrzeugs gewünschten Fahrzustand, also beispielsweise eine Beschleunigung des Kraftfahrzeugs, zu erreichen.The Requirements for a modern internal combustion engine with regard to a reduction of the spent fuel and exhaust gases are getting higher. For this reason, it is necessary to meter the fuel in the combustion chamber of the internal combustion engine to further improve, in particular to determine the metered fuel mass even more accurate. To this Purpose is not only the angular position in known internal combustion engines the throttle valve by means of an angle sensor, but also the Pressure in the intake pipe after the throttle valve using a pressure sensor certainly. This angular position and this pressure after the throttle are then used to the associated fuel mass to be injected to calculate one that is required by the driver of the Motor vehicle desired Driving condition, so for example an acceleration of the motor vehicle, to reach.
Bei der genannten Berechnung ist als weiterer Parameter der Druck im Ansaugrohr vor der Drosselklappe von Vorteil. Dieser Druck entspricht etwa dem Umgebungsdruck und kann mit Hilfe eines weiteren Drucksensors gemessen werden. Ein derartiger weiterer Drucksensor ist jedoch mit zusätzlichen Kosten verbunden.at The above calculation is another parameter of the pressure in Intake pipe in front of the throttle valve is an advantage. This pressure corresponds about the ambient pressure and can with the help of another pressure sensor be measured. However, such another pressure sensor is with additional costs connected.
Aufgabe der Erfindung ist es, ein Verfahren zum Betreiben einer Brennkraftmaschine zu schaffen, bei dem die Berechnung der in den Brennraum einzuspritzenden Kraftstoffmasse möglichst genau durchführbar ist, trotzdem aber die für die Durchführung des Verfahrens erforderlichen Kosten gering sind. Weitere Aufgabe der Erfindung ist es, eine entsprechende Brennkraftmaschine zu schaffen, bei der die Berechnung der in den Brennraum einzuspritzenden Kraftstoffmasse möglichst genau durchführbar ist, trotzdem aber die für die Durchführung erforderlichen Kosten gering sind.task The invention is a method for operating an internal combustion engine in which the calculation of the injected into the combustion chamber Fuel mass as possible exactly feasible is, but still for the implementation costs are low. Further task the invention is to provide a corresponding internal combustion engine, in the calculation of the fuel mass to be injected into the combustion chamber preferably is exactly feasible, anyway, but the for the implementation required costs are low.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art bzw. bei einer Brennkraftmaschine der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß zumindest aus der Winkelstellung der Drosselklappe ein Verhältnis des Drucks vor und nach der Drosselklappe berechnet wird, und daß aus dem berechneten Verhältnis des Drucks vor und nach der Drosselklappe und aus dem gemessenen Druck nach der Drosselklappe der Druck vor der Drosselklappe berechnet wird, gemäß Anspruch 1 oder 9.These Task is in a method of the type mentioned or in an internal combustion engine of the type mentioned according to the invention thereby solved, that at least from the angular position of the throttle a ratio of Pressure before and after the throttle is calculated, and that from the calculated ratio the pressure before and after the throttle and from the measured pressure after the throttle, the pressure in front of the throttle is calculated will, according to claim 1 or 9.
Mit Hilfe der gemessenen Winkelstellung der Drosselklappe und dem gemessenen Druck nach der Drosselklappe wird somit der Druck vor der Drosselklappe ermittelt. Hierzu werden Modelle verwendet, mit denen das Verhalten des dem Ansaugrohr zugeführten Massenstroms nachgebildet wird. Insbesondere wird mit dem Modell das Verhältnis des Drucks vor und nach der Drosselklappe ermittelt. Der daraus dann berechnete Druck vor der Drosselklappe wird von dem Steuergerät zur Ermittlung der in den Brennraum einzuspritzenden Kraftstoffmasse weiterverwendet. Dabei hat sich gezeigt, daß die in Abhängigkeit von dem berechneten Druck vor der Drosselklappe ermittelte Kraftstoffmasse sehr genau den von dem Fahrer erwünschten Fahrzustand, beispielsweise eine Beschleunigung des Kraftfahrzeugs, bei gleichzeitiger geringem Kraftstoffverbrauch und geringer Abgaserzeugung erfüllt.With Help the measured angular position of the throttle and the measured Pressure after the throttle is thus the pressure in front of the throttle determined. For this purpose models are used with which the behavior of the intake pipe supplied Mass flow is simulated. In particular, with the model The relationship the pressure before and after the throttle valve determined. The result then calculated pressure before the throttle is detected by the control unit the fuel mass to be injected into the combustion chamber continues to be used. It has been shown that the dependent on from the calculated pressure before the throttle detected fuel mass very exactly the desired by the driver driving condition, for example an acceleration of the motor vehicle, at the same time low Fuel consumption and low exhaust gas generation met.
Bei einer vorteilhaften Weiterbildung der Erfindung wird der gemessene Druck nach der Drosseklappe durch das berechnete Verhältnis des Drucks vor und nach der Drosselklappe dividiert. Es wird also insgesamt das Verhältnis des Drucks vor und nach der Drosselklappe unter anderem aus der Winkelstellung der Drosselklappe ermittelt. Der gemessene Druck nach der Drosselklappe wird dann durch dieses Verhältnis dividiert, woraus sich der rechnerische Druck vor der Drosselklappe ergibt.at an advantageous embodiment of the invention is the measured Pressure after the throttle valve by the calculated ratio of pressure divided before and after the throttle. So it will be total The relationship the pressure before and after the throttle valve, among other things from the angular position the throttle detected. The measured pressure after the throttle is then through this ratio divided, resulting in the computational pressure in front of the throttle results.
Besonders zweckmäßig ist es, wenn aus der Winkelstellung der Drosselklappe und dem berechneten Druck vor der Drosselklappe der Druck nach der Drosselklappe berechnet wird. Damit liegt ein gemessener Wert und ein berechneter Wert für den Druck nach der Drosselklappe vor. Diese beiden Werte können von dem Steuergerät bei der Berechnung des genannten Modells verwendet werden.Especially is appropriate it, if from the angular position of the throttle and the calculated Pressure in front of the throttle valve, the pressure calculated after the throttle becomes. This is a measured value and a calculated value for the pressure after the throttle. These two values can be read by the controller at the Calculation of said model can be used.
Bei einer vorteilhaften Weiterbildung der Erfindung wird aus der Winkelstellung der Drosselklappe und dem berechneten Druck vor der Drosselklappe ein Massenstrom über die Drosselklappe berechnet. Dabei ist es besonders vorteilhaft, wenn aus dem Massenstrom über die Drosselklappe der Druck nach der Drosselklappe berechnet wird. Auch der auf diese Weise berechnete Massenstrom kann von dem Steuergerät insbesondere bei der Berechnung der in den Brennraum einzuspritzenden Kraftstoffmasse weiterverwendet werden.at An advantageous development of the invention is the angular position the throttle and the calculated pressure in front of the throttle a mass flow over the throttle is calculated. It is particularly advantageous when out of the mass flow over the throttle valve is calculated the pressure after the throttle. Also, the mass flow calculated in this way can in particular by the control unit used in the calculation of the fuel mass to be injected into the combustion chamber become.
Bei einer vorteilhaften Ausgestaltung der Erfindung wird aus dem berechneten Druck nach der Drosselklappe und dem berechneten Druck vor der Drosselklappe das Verhältnis des Drucks vor und nach der Drosselklappe berechnet. Damit ergibt sich insgesamt das folgende iterative Verfahren. Es wird das Verhältnis des Drucks vor und nach der Drosselklappe unter anderem aus der Winkelstellung der Drosselklappe ermittelt. Der gemessene Druck nach der Drosselklappe wird dann durch dieses Verhältnis dividiert, woraus sich der rechnerische Druck vor der Drosselklappe ergibt. Dieser berechnete Druck vor der Drosselklappe wird dann wieder dazu verwendet, das Verhältnis des Drucks vor und nach der Drosselklappe zu beeinflussen.at An advantageous embodiment of the invention is calculated from the Pressure after the throttle and the calculated pressure in front of the throttle The relationship the pressure before and after the throttle valve is calculated. This results Overall, the following iterative process. It will be the ratio of Pressure before and after the throttle valve, among other things from the angular position the throttle detected. The measured pressure after the throttle is then divided by this ratio, which results in the calculated pressure in front of the throttle valve. This calculated pressure in front of the throttle will then be added again used the ratio the pressure before and after the throttle to influence.
Besonders zweckmäßig ist es, wenn der berechnete Druck vor der Drosselklappe mittels eines Tiefpaßes geglättet wird. Damit unterliegt der berechnete Druck keinen schnellen Änderungen, was für die weiteren Berechnungen durch das Steuergerät von Vorteil ist.Especially is appropriate it, when the calculated pressure before the throttle valve is smoothed by means of a low-pass filter. Thus, the calculated pressure is not subject to rapid changes, what kind of the further calculations by the control unit is advantageous.
Bei einer vorteilhaften Weiterbildung der Erfindung wird aus der Winkelstellung der Drosselklappe und aus dem berechneten Druck vor der Drosselklappe eine Luftfüllung in dem Brennraum der Brennkraftmaschine berechnet wird. Diese berechnete Luftfüllung wird dann von dem Steuergerät bei der Berechnung der in den Brennraum einzuspritzenden Kraftstoffmasse weiterverwendet.at An advantageous development of the invention is the angular position the throttle and the calculated pressure in front of the throttle an air filling is calculated in the combustion chamber of the internal combustion engine. This calculated air charge is then from the controller in the calculation of the fuel mass to be injected into the combustion chamber on.
