Method for starting an internal combustion engine

摘要

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.

1. A method of starting an internal combustion engine, comprising:
driving the internal combustion engine by starting and operating a pneumatic starter motor supplied by a compressed air feed controlled by a compressed air valve, the compressed air valve being switchable between a completely open position and a completely closed position; and after said starting of the pneumatic starter motor, breaking off a starting process upon detection of water hammer due to an occurrence of at least one of:
an angular acceleration a drive shaft of the internal combustion engine remains below a predetermined acceleration value;within a predetermined first time period, an actual rotary speed of the drive shaft remains below a predetermined first rotary speed threshold value; andwithin a predetermined second time period, an average rotary speed of the drive shaft remains below a predetermined second rotary speed threshold value; wherein said starting of the pneumatic starter motor is effected by completely opening the compressed air valve; and wherein said breaking off the starting process is effected by completely closing the compressed air valve.
