Combined with the Peugeot and Citroën diesel HDi diesel engines, this system is installed in more than 2 million vehicles, both manual and robotic gearboxes. This new generation,Start & Stop, is distinguished by the integration of electronics control on electrical machine.
As in the first generation, the micro-hybrid system allows the motor to be automatically switched off, for example during a red light or in a traffic jam, and re-starts when a power is requested.
To optimize fuel economy and make driving more flexible, the Start & Stop is distinguished by cutting off the engine before the vehicle is completely stopped as soon as the vehicle travels at less than 8 km / h with a robotic less than 20 km / h with a manual gearbox. Its restart is immediate (under 400 msec), totally silent and vibration-free, even if the driver unexpectedly changes notice during shutdown.
Valeo offers a range of products allowing the Stop & Start function, based either on an alternator starter or on a reinforced starter, thus enabling each manufacturer to introduce this function according to its own strategy.
