WASHINGTON - Volkswagen of
America, Inc. today unveiled its cleanest diesel ever for the
U.S., the Jetta TDI. Additionally, the company announced that
this new clean diesel will be available to the U.S. market in
the spring of 2008. This Jetta TDI will meet emissions standards
applicable in all 50 states, including the most stringent "TIER
2/BIN 5" or "LEV II/LEV" requirement limiting nitrogen oxide (NOx)
emissions to 0.05 g/mile.
This clean diesel Jetta meets the
lowest emissions standards without the use of urea injection.
Instead, a nitrogen oxide storage catalyst reduces NOx emissions
by up to 90 percent. The engine management system in the Jetta
changes operating modes periodically to treat the NOx that has
been stored in the catalytic converter. A particulate filter in
the exhaust system further reduces emissions.
The Jetta TDI is one of the first
products of the BLUETEC offensive initiated jointly by Audi,
Mercedes-Benz, and Volkswagen. The goal of this partnership is
to establish the concept of BLUETEC as a uniform label for clean
and highly fuel efficient diesel-powered cars and SUVs with
50-state compliant engines. BLUETEC denotes diesel power plants
that comply with the strictest emissions regulations of the US
market. The technologies individually developed by each
manufacturer serve to reduce NOx in particular -- an exhaust
element more prevalent in a diesel engine. |
