LUDWIGSBURG, Germany, March 10 /PRNewswire/ -- MANN+HUMMEL is a leader in
combining engineering technology with the use of innovative components crafted
of advanced materials. Working with sophisticated plastics and composites,
they are experienced in providing automakers with the tools required to
produce environmentally responsible, fuel-efficient vehicles. Many of their
most advanced products will be featured at the SAE 2005 World Congress in
Detroit, April 11 - 14, 2005.
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. The SAC contains a turbine wheel and compressor wheel.
The turbine, which is driven by the pressure difference at the throttle body,
powers the compressor. The compressor provides the exhaust system with fresh
air, without the use of a bulky, heavy and expensive electric air pump.
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.
Tests of the secondary air charger show that they have a higher level of
startup performance when compared to a secondary air pump. Engine
measurements have demonstrated that 80% of the rated mass airflow is reached
very quickly. In addition, the plastic wheels in MANN+HUMMEL's Secondary Air
Charger have the added advantage of reducing the size and weight of the SAC.
MANN+HUMMEL, a development partner and original equipment supplier for the
international automotive industry, 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 Evaporative Emission Standards 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 are forced to 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 is also
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.
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 and
Hydrocarbon traps. These products, including an Air Cleaner with integrated
Beauty Cover and Hydrocarbon Trap, will be displayed at the MANN+HUMMEL SAE
2005 exhibit, in booth # 1726.
