DETROIT, April 3 /PRNewswire/ -- MANN+HUMMEL, a leader in combining
engineering technologies, uses innovative components crafted of advanced
materials, sophisticated plastics and composites to provide automakers with
the tools required to produce environmentally responsible, fuel-efficient
vehicles. Many of their most advanced products will be featured at the SAE
2006 World Congress in Detroit, April 3 - 6, 2006.
MANN+HUMMEL is a leader in the development of Hydrocarbon Absorption
technology to meet expanded California emissions requirements. The CARB
(California Air Resources Board) Evaporative Emission Standards are the most
stringent in the world. The CARB PZEV (Partial Zero Emissions Vehicle)
regulations are among the most difficult to achieve. MANN+HUMMEL has created
a solution to address the CARB PZEV requirements for California and the other
Green States (MA, ME, NY and VT).
The solution consists of hydrocarbon adsorptive media permanently
installed in the vehicle's air intake system -- usually in the air cleaner
assembly. The media collects, or traps, all hydrocarbon fumes emanating from
the intake system after engine shutdown and holds them until the engine is re-
started; at which time the fumes are released into the incoming air stream and
burned in the combustion process.
Only vehicles that must pass the CARB PZEV requirements require an HC-
trap. However, the MANN+HUMMEL solution is sufficiently cost effective that
the OEMs could choose to spread their HC-trap costs over a given vehicle's
entire volume to reduce manufacturing complexity. In addition, MANN+HUMMEL's
HC-trap can be integrated into the air cleaner system in either a 'full-flow'
or 'bypass' version for greater packaging flexibility. Ever sensitive to
dealing with the need to recycle components, MANN+HUMMEL also is the source of
the world's first all-plastic oil module and metal free filter elements. The
module is recyclable and the element completely incinerateable at the end of
its service life.
In the U.S., new diesel emissions regulations and cleaner diesel fuels
slated for 2006 raise the need for innovative engine-performance solutions.
Both U.S. and European automakers recognize the opportunities created by these
changes and are planning to increase their offerings of clean diesel-powered
vehicles to their customers. One technology that allows for the reduction of
NOx exhaust emissions is Urea Injection. Urea, an ammonia-based aqueous
solution, is injected into the exhaust stream where it reacts with the NOx to
release harmless Nitrogen and water vapor into the atmosphere. MANN+HUMMEL
has developed a urea filtration module that integrates the functions of
filtration, heating, and temperature- and pressure-regulation sensors, all
integral components for these Urea injection systems.
One of the product innovations, the Secondary Air Charger, helps meet
stringent emissions requirements by introducing fresh air into the exhaust
system to improve the oxidation of NMHC and CO and reducing the time to heat
up the catalyst.
The Secondary Air Charger (SAC) is integrated into the air induction
system of the engine. It consists of a turbine wheel and compressor wheel.
The turbine, driven by the pressure difference at the throttle body, powers
the compressor. The compressor provides the exhaust system with fresh air.
Compared to secondary air pumps, the secondary air charger provides
advantages in performance, packaging and weight. The secondary air charger
starts directly at engine start-up, with the onset of manifold vacuum and has
a higher level of startup performance than air pumps.
MANN+HUMMEL, is a development partner and original equipment supplier for
the international automotive industry.
As an experienced, recognized pioneer in the development of air, oil and
fuel filtration systems, MANN+HUMMEL is continuing to provide automakers with
innovative, high-quality product solutions, like the Secondary Air Charger,
Hydrocarbon traps and urea filter. These products, including an Air Cleaner
with integrated Beauty Cover and Hydrocarbon Trap, will be displayed at the
MANN+HUMMEL SAE 2006 exhibit, in booth # 1532.
