Abstract: The invention proceeds from a system for adjusting a motor vehicle transmission, which is changeable in its transmission gear ratio, the transmission having an efficiency characteristic which is dependent on the transmission gear ratio. A first quantity is detected which represents the actual transmission output rpm and a second quantity is determined which represents a desired value for the drive torque. Then, a desired rpm of the vehicle engine is determined at least in dependence upon the detected first quantity and the determined second quantity and in dependence upon the efficiency characteristic of the transmission. The adjustment of the transmission gear ratio takes place in dependence upon the desired rpm of the vehicle engine which is so determined. With the invention, transmission influences are considered in the determination of the optimal transmission gear ratio within a system for the coordinated drive train control.

The injector has an upper lip recessed by at least 2 mm with reference to a lower lip of the injector.

Abstract: The synchronous or asynchronous electrical machine for an internal combustion engine can operate alternately in a starter mode during engine starting and a generator mode during engine operation in order to eliminate the need for a separate starter and generator. The electrical machine includes a two-stage planetary gear device coupled to a shaft of the internal combustion engine. The two-stage planetary gear device includes two stages with ring gears and respective braking devices assigned to the two stages that prevent the ring gears of those stages from rotating when engaged therewith. The two-stage planetary gear device operates with different gear ratios in the starter mode and the generator mode. The gear ratio in the starter mode is between 4 and 60 and between 1.6 and 4 in the generator mode. The ratio of the gear ratios in the starter mode and the generator mode must be at least two.
