    摘要： The invention relates to a method for operating a piston pump (10) which is driven by means of a coil (1) of an electromagnet. A piston (2) of the piston pump (10) can be moved in a cylinder (3) for pumping purposes by means of the electromagnet. A voltage (U) is applied to the coil (1) during a switch-on period such that a current flows through the coil (1) and the piston (2) is accelerated, said voltage being applied by means of an actuation device (11). A time curve of an electric state variable (I, U) of the coil (1) is qualitatively detected, and the curve or a curve derived therefrom is analyzed in order to detect an impact of the piston (2) against a stop. The invention further relates to an actuation device and a piston pump.

    摘要： A method for adapting a transition compensation based on a lambda value change for operating an engine, which includes a combustion chamber having a first inlet opening connected to a first intake pipe having a first injector. The chamber includes a second inlet opening connected to a second intake pipe having a second injector. During normal operation, a predetermined fuel quantity is injected, and this quantity includes a first and second fuel quantities to be injected respectively via the first and second openings. In a first task, the first injector remains closed, and in a second task, the first injector is opened again. In the second task, a first test fuel quantity is injected into the combustion chamber via the first opening and a second test fuel quantity is injected via the second opening, the first and second test fuel quantities making up the predetermined fuel quantity.
