Die Hysterese der Piezokeramik von 5 % bis 25 % ist sehr hoch und schränkt dadurch die Genauigkeit der Brennraumdruckmessung deutlich ein.

Inglês

The hysteresis of the piezoceramic of 5% to 25% is very high and thereby significantly restricts the accuracy of the combustion chamber pressure measurement.

Es ist ferner möglich, das Öffnen und/oder Schließen des Gaswechselventils 1 durch Saugrohrdruckmessung und/oder Brennraumdruckmessung zu detektieren.

Inglês

It is also possible to detect the opening and/or closing of the gas exchange valve by measuring structure-born noise, airborne noise, intake manifold pressure, and/or combustion chamber pressure.

Verfahren zum Bestimmen der Verbrennungsluftmasse, die in einem oder mehreren Zylindern einer Brennkraftmaschine für eine bestimmte Verbrennung zur Verfügung steht, wobei über eine Luftmasssenmessung im Saugrohr laufend die angesaugte Luftmasse gemessen wird, wobei diese gemessene Luftmasse einer Korrektur unterzogen wird, so daß sie der Verbrennungsluftmasse entspricht, dadurch gekennzeichnet, daß über eine Brennraumdruckmessung der Druck in jedem Zylinder gemessen wird, daß aus dem Druckverlauf während eines Kompressionstakts die Verbrennungsluftmasse für jeden Zylinder bestimmt wird und daß durch eine Adaption der Korrektur der Unterschied zwischen der über die Luftmassenmessung und die Brennraumdruckmessung ermittelten Verbrennungsluftmassen kompensiert wird.

Inglês

Method for determining the combustion air mass which is available for a certain combustion in one cylinder or a plurality of cylinders of an internal combustion engine, the induced air mass being continuously measured by means of an air mass measurement in the induction pipe and this measured air mass being subject to a correction so that it corresponds to the combustion air mass, characterized in that the pressure in each cylinder is measured by means of a combustion space pressure measurement, in that the combustion air mass for each cylinder is determined from the variation of pressure during a compression stroke and in that compensation is provided for the difference between the combustion air masses determined by means of the air mass measurement and the combustion space pressure measurement by means of an adaptation of the correction.

Verfahren zum Ansteuern eines Gaswechselventils (1) zur Einstellung der Leistung eines Verbrennungsmotors durch Öffnen und Schließen des Gaswechselventils (I), wobei das Öffnen und/oder Schließen des Gaswechselventils (1) in Abhängigkeit einer Verzugszeit beim Öffnen und/oder Schließen des Gaswechselventils (1) erfolgt, wobei das Gaswechselventil (1) zur Bestimmung der Verzugszeit eine vorgegebene Verstellzeit (T AN ) lang verstellt und das Öffnen und/oder das Schließen des Gaswechselventils (1) detektiert wird, dadurch gekennzeichnet, dass das Öffnen und/oder Schließen des Gaswechselventils (1) durch Luftmassenmessung, Saugrohrdruckmessung, zylinderindividuelle Luftmassenmessung, zylinderindividuelle Saugrohrdruckmessung und/oder zylinderindividuelle Brennraumdruckmessung detektiert wird.

Inglês

Method for activating a gas exchange valve (1) for setting the power of an internal combustion engine by means of the opening and closing of the gas exchange valve (1), the opening and/or closing of the gas exchange valve (1) taking place as a function of a delay time in the opening and/or closing of the gas exchange valve (1), the gas exchange valve (1) being adjusted to a predetermined adjustment time (T AN ) in order to determine the delay time, and the opening and/or closing of the gas exchange valve (1) being detected, characterized in that the opening and/or closing of the gas exchange valve (1) are/is detected by air-mass measurement, suction-pipe pressure measurement, cylinder-individual air-mass measurement, cylinder-individual suction-pipe pressure measurement and/or cylinder-individual combustion-space pressure measurement.

Nach beendeter Ultraschallaufzeitmessung steht das piezoelektrische Sensorplättchen bei dieser ersten Verfahrensvariante wieder für Brennraumdruckmessungen zur Verfügung.

Inglês

Once ultrasonic delay measurement has been completed, in the case of this first variant of the method according to the invention, the piezoelectric sensor platelet is available again for combustion-chamber pressure measurements.
