Abstract: A method for starting an internal combustion engine, particularly a stationary gas engine, includes driving the engine by at least one starter motor. The starting process is interrupted once the starter motor has been started if the angular acceleration of the internal combustion engine remains below a predefinable acceleration value and/or if, within a predefinable first time period, the actual rotational speed remains below a predefinable first rotational speed threshold value and/or if, within a predefinable second time period, the average rotational speed of the internal combustion engine remains below a predefinable second rotational speed threshold value. The starter motor is designed as a pneumatic starter motor and the compressed air supply thereof is controlled by a compressed air valve which can be switched between a fully opened position and a fully closed position, the pneumatic starter motor being started by the compressed air valve being fully opened.

Abstract: The invention relates to a method for starting an internal combustion engine (1), particularly a stationary gas engine, which is driven by at least one starter motor (2). The starting process is interrupted once the starter motor (2) has been started if the angular acceleration (a) of the internal combustion engine (1) remains below a predefinable acceleration value and/or if, within a predefinable first time period (tA), the actual rotational speed (n) remains below a predefinable first rotational speed threshold value (nA) and/or if, within a predefinable second time period, the average rotational speed of the internal combustion engine (1) remains below a predefinable second rotational speed threshold value.
