Estimating the term…
A timing gear for triggering a gas exchange valve for adjusting the output of an internal combustion engine through the opening and closing of the gas exchange valve and a method for triggering the gas exchange valve, where at least one of the opening and closing of the gas exchange valve is executed as a function of a delay interval when opening and/or closing the gas exchange valve and where in order to determine the delay time, the gas exchange valve is adjusted for the length of a predetermined adjustment interval and at least one of the opening and closing of the gas exchange valve is detected.
A method for triggering a gas exchange valve (1) for adjusting the output of an internal combustion engine by opening and closing the gas exchange valve (1), where at least one of the opening and closing of the gas exchange valve (1) occur(s) as a function of a delay interval during at least one of the opening and closing the gas exchange valve (1), characterized in that in order to determine the delay interval, the gas exchange valve (1) is adjusted for the length of a predetermined adjustment interval (TAN) and at least one of the opening and closing of the gas exchange valve (1) is detected, wherein at least one of the opening and closing of the gas exchange valve (1) is detected by at least one means of measuring structure-borne noise, airborne noise, air mass, intake manifold pressure, cylinder-specific air mass, cylinder-specific intake manifold pressure, and cylinder-specific combustion chamber pressure.
