Valeo offers a complete range of Stop-Start solutions, both belt driven ( i-StARS starter-alternator) and starter based ( ReStart reinforced starter).
In the city, vehicles are stationary for almost 35% of the time, with their engine’s idling needlessly. The Stop-Start system automatically switches the engine off when the vehicle is at a standstill and restart the engine immediately, as soon as the driver lifts his foot off the brake or disengages the clutch, leading to a significant reduction in CO2 emissions.
Two Valeo systems, the i-StARS starter-alternator and the ReStart reinforced starter, make this automation possible. These systems are compatible with gasoline and diesel engines, and both manual and automatic gearboxes.
The Stop-Start system provides fuel savings of up to 6% in European standard mixed cycle use, and savings of up to 15% in congested city driving.
