Abstract
The invention relates to a pulse starting method for an internal combustion engine in which, during a wind-up phase, a flywheel mass is accelerated in a rotary driven fashion and then during a coupling phase, the rotating flywheel mass is coupled to a rotatably supported shaft of the engine, preferably the crankshaft, in order transmit torque, which is distinguished by the fact that during the wind-up phase ( ) and/or the coupling phase ( ), the rotational speed progression of the flywheel mass ( ) is evaluated, that based on this evaluation, a deduction is made as to whether a successful start of the engine ( ) is possible, and that if a successful start is not expected, the shaft ( ) is used to bring the engine ( ) into an operating position that is favorable for a subsequent second starting attempt.
