New Valeo Micro-Hybrid System to Equip PSA Peugeot Citroen e-HDi Diesel Models

Paris, June 9, 2010 (ots/PRNewswire)

Valeo announces that its second
generation Stop-Start system will be launched by PSA Peugeot Citroen
in the third quarter of 2010. The system, coupled with the HDi diesel
engines of the Peugeot and Citroen brands, will be featured on both
manual and automated manual transmission  models and will equip a
million vehicles by 2013.
This new generation micro-hybrid system, called i-StARS, differs
from  the previous generation in that the control electronics are
integrated into  the electrical machine.
The micro-hybrid system automatically cuts off the vehicle's
engine at a red light or in a traffic jam and restarts it when engine
power is solicited. CO2 emissions are reduced by 5g per kilometer on
average, and by up to 15% in congested urban traffic.
To optimize fuel savings and make driving in the Stop-Start mode
smoother, i-StARS can cut off the engine even before the vehicle
comes to a complete stop, that is, as soon as the vehicle's speed
falls below 8 km/h with an automated transmission and 20 km/h with a
manual transmission. Engine re-start is immediate (400 msec),
noiseless and with no vibrations, even if the driver suddenly changes
his or her mind about stopping. In addition, since the engine cut-off
phases are longer and more frequent than with other systems, fuel
savings are higher.
Valeo offers two micro-hybrid systems, either starter-alternator
or reinforced starter-based, enabling automakers to introduce this
function in line with their brand strategy. Since the system was
first marketed, the Group has booked orders to equip 50 vehicle
models from more than 10 different automakers.
Valeo is an independent industrial Group fully focused on the
design, production and sale of components, integrated systems and
modules for the automotive industry, mainly for CO2 emissions
reduction. Valeo ranks among the world's top automotive suppliers.
The Group has 118 plants, 21 Research centers, 40 Development
centers, 10 distribution platforms and employs 55,100 people in 27
countries worldwide.
