What is Peugeot’s e-HDI Start Stop System?



  1. 0 Votes

    The e-HDI is a modified booster module that is part of PSA Peugeot Citroen’s mild-hybrid system. The ultracapacitor model is innovative because it can be used to restart a diesel engine in 400 milliseconds, twice as fast as a conventional starter motor. To achieve this, the system utilizes a 2.2 kilowatt generator that increases power from its preceding model by 70%. The mild-hybrid module is also somewhat green; it increases fuel economy by 15%, and automatically shuts off the engine if the speed drops below 20 kilometers per hour.
