What Is an Integrated Starter Generator
An integrated starter generator (ISG) is the combination of a starter, generator and flywheel system into one auto part. It is used to enhance fuel efficiency and vehicle performance on automobiles with combustion engines.
Purpose
When a vehicle comes to a complete stop, the integrated starter generator switches the engine off. When the accelerator is pressed, it starts the engine again, thereby saving gas that is usually wasted when a vehicle is in idle.
Benefits
Integrated starter generators offer faster vehicle cranking than a 12-volt starter. Also, they save fuel by reducing idling time when a vehicle is stopped.
Other Functions
Regenerative braking -- which happens when a vehicle decelerates by way of electric power -- is aided by the integrated starter generator. Also, the ISG functions as an alternator by generating electric power in a running vehicle and charging the battery.
