Continental Automotiventegrated Starter Generator (ISG) replaces the conventional starter, generator and flywheel of the engine and provides an auxiliary function as a convenient automatic vehicle start-stop system for further improved fuel efficiency. The system switches off the combustion engine at zero load – such as when standing at a traffic light - and automatically restarts it in less than one hundred milliseconds when the gas pedal is pressed. The pulse-start technology accelerates the combustion engine to the required cranking speed (idle speed) and only then initiates the combustion process for instant ignition, a feature that helps reduce both fuel consumption and emissions. ISG also optimizes the use of electric energy, further reducing fuel consumption and emissions.
The system's extremely compact dimensions allow it to be placed directly on the crankshaft between the engine and the transmission. High electric power output, even at low speeds, enhances the performance of comfort and convenience features. These include the air conditioner, seat heater or rear-window defroster.
The introduction of the ISG also will bring about the transition from a 14 to a 42-volt vehicle electrical system, a development that has been generating interest in the automotive industry, driven largely by the increasing content of electronics solutions in vehicles.
The ISG reaches a peak generator output of 8 kW with an efficiency of more than 80 percent across the entire speed range.
