Abstract:
A pulse starting method for an internal combustion engine having a crankshaft, said method comprising the steps of:a) during a wind-up phase, accelerating a flywheel mass in a rotary driven fashion in order to rotate the flywheel mass; b) then during a coupling phase following the wind-up phase, coupling the rotating flywheel mass to the crankshaft of the engine, in order transmit torque to the crankshaft for starting the engine; c) during at least one of the wind-up phase (15) and the coupling phase (21, 22), evaluating a rotational speed progression (n(t)) of the flywheel mass (3) to obtain evaluation results; d) deducing whether a successful start of the engine is possible from the evaluation results obtained in step c); and e) if said successful start is not expected, the engine is brought into an operating position favorable for a subsequent starting attempt by means of the crankshaft.
