2.1.2. Electrical Systems
The Electrical Systems Product Family covers key functions of the
vehicle, such as electrical energy generation and management and
engine ignition, aiming to provide greater driving comfort and to
reduce fuel consumption and pollutant emissions:
■ the StARS micro-hybrid system on the market; this system
stops the engine when the vehicle comes to a halt and restarts
it immediately and silently when the driver releases the brake,
giving fuel savings of up to 28% in heavy urban traffic. This system
is under further developments, especially towards hybridization
(See “Powertrain Efficiency”, section 2.1.1. of “Key Events in
2007”);
Other products produced by Valeo Electrical Systems include:
■
■
■
■
■
starters;
alternators;
battery management systems;
renovated alternators and starters for the aftermarket;
electromagnetic retarders for trucks and buses.
2.1.3. Engine Cooling
This Product Family develops and manufactures components and
modules for a full range of powertrain cooling functions, with a
view to reducing pollution and fuel consumption, and enhancing
passenger comfort.
In 2007, Valeo Engine Cooling focused on the following innovations
in particular:
UltimateCoolingTM ■
, which offers both improved engine
performance and a reduction in fuel consumption and pollutant
emissions. (For more technical detail, see “Powertrain Efficiency”,
section 2.1.1. of “Key Events in 2007”);
■ the new modular front end, compliant with Phase 1 of the
“Pedestrian Protection” regulation, launched in 2007, and specific
solutions in terms of shock and energy absorption, pending
the adoption of Phase 2, which comes into force in Europe in 2010.
In combination with UltimateCooling, these allow automakers
to conform to the new regulations;
■ with regard to the new European regulation prohibiting the use
of the refrigerant gas R134a on vehicles entering production as of
2011, a new range of exchangers compatible with the new
CO refrigerant fluid (replacing R134a) has been developed.

In addition, Valeo is assessing alternative refrigerants and their
impact on current systems;

Activity
The Group
the Themis TM valve, built into the engine cooling circuit, is an
electronic management system for engine cooling and heating.
It is being developed for the first mass-produced applications,
with an extended range of electronic valves to cover all engines.
The gains offered by this system in terms of fuel savings and
comfort enhancement support the trend towards the downsizing
of today’s engines, one of the most promising ways of generating
fuel savings.

front end modules.
2.1.4. Compressors
Valeo Compressors develops and produces compressors for air
conditioning systems. The solutions it offers include controlled
air conditioning compressors, with reduced energy requirements.
Valeo Compressors contributes to the Powertrain Efficiency Domain
with innovations such as:
■ the R744 Compressor, a key component in the next generation
of air conditioning systems which will use the natural and
environmentally friendly CO coolant.

This Product Family also develops and produces the following
products:
■
■
■
pallet compressors;
fixed-cylinder compressors;
variable-cylinder compressors.
2.1.5. Transmissions
< Contents >
Valeo Transmissions develops and produces systems that transfer
engine power to the powertrain of passenger cars and industrial
vehicles. The solutions it offers incorporate innovative systems that
dampen noise, vibrations and harshness. This Product Family is
present in all major markets in both the original equipment and
aftermarket segments.
Valeo Transmissions has developed innovations that include:
■ the double dry clutch, a technology combining two clutches
and their electromechanical actuators, which allows the design
of automated manual (double clutch) transmissions, offering
good fuel savings compared to classic hydraulic automatic
transmissions;
