Abstract

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.
