A new wave of leading-edge research is about to get under way
for TTI thanks to a portable, accurate emission-testing device
acquired by the Institute’s Air Quality and Transportation
Modeling programs. The device allows researchers to get an
accurate assessment of emissions from any type of internal
combustion engine in real-life settings. Up until recently,
testing had to be performed only in the laboratory.
“The portability of this emission testing equipment means
we can test a whole range of vehicles, anytime, anyplace,” says
Dennis Perkinson, manager of the Transportation Modeling Program
and visiting assistant professor in the Department of Landscape
Architecture and Urban Planning. “It will give us answers
to numerous questions that we couldn’t really answer until
Those questions include: What’s safer for the environment
and our children, bio-diesel or low-sulfur diesel school busses?
With suggested higher speed limits for the proposed Trans-Texas
Corridor, are engine emissions better or worse at speeds above
70 miles per hour? Are Mexican company-owned trucks emitting
more pollutants than U.S-owned trucks?
“We already have numerous research projects coming up
because of this device and our track record in this field,” says
Associate Research Engineer Joe Zietsman. “And we think
it has the potential of opening the doors for a lot more research.”
At least one of the projects will include the use of the banked
9-mile oval track at the Pecos Research and Testing Center, which
will accommodate vehicles at speeds of up to 200 miles per hour.
