摘要 |
The invention relates to a start method and a start arrangement for an internal combustion engine (10) of motor vehicles having a crankshaft (11) connected to an electric machine (14) for cranking the engine. Crankshaft position and rotation are detected by a start control apparatus (19) and evaluated for controlling each start operation of the engine. The crankshaft (11) is first brought by the electric machine (14) into a start position during a positioning phase for each start operation. For achieving the shortest possible start times and smallest possible crank torque of the electric machine, it is provided that, in a start phase, which follows the positioning phase, a first combustion with reduced compression and reduced charge level is triggered in the at least first cylinder going into compression which combustion supports the crank torque of the electric machine (14).
