The Integrated 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.
The MEA RDS systems test the ISG also will output 14 to a 42-volt vehicle electrical system with peak generator output of 8 kW the system tests the torque, speed, efficiency across all predefined speeds ranges.
In addition the systems tests the Dynamic behaver during the acceleration period, including the torque and efficiency of the ISG during the very short acceleration time.
