Starter motor generator: Notes

The starter unit enables comfortable starting of the combustion engine from a vehicle standstill or during electric driving via the starter generator.

The starter motor generator is integrated in the belt drive. Using a starter generator means that a second belt tensioner is required.

The crankshaft starter generator enables a comfortable transition from electric driving to driving powered by the combustion engine. The energy supplied by the auxiliary battery makes it possible to quickly start the engine with very low noise without requiring an additional torque in the electrical machine.
