PITTSBURGH, July 9, 2014 /PRNewswire/ -- The U.S.
Environmental Protection Agency (EPA) has selected ANSYS (NASDAQ:
ANSS) simulation solutions to model in-cylinder combustion to
develop an advanced test engine that will demonstrate fuel-saving
and emissions-reducing technologies. The EPA's test engine will
help establish the feasibility of meeting recently issued fuel
standards through improvements to combustion chamber geometries,
fuel injection strategies, fuel composition, valve timing and
intake conditions.
While physical prototyping and direct tests on real engine
hardware can guide engine design, they are very costly and
time-intensive. By using ANSYS FORTE, the EPA can experiment with
engine design in a virtual setting. As a result, its engineers can
quickly and inexpensively make multiple design iterations. ANSYS
acquired FORTE as part of its acquisition of Reaction Design
earlier this year.
"The goal of our Clean Automotive Technology program is to
research, evaluate and develop advanced engine and drivetrain
technologies that help increase fuel efficiency, reduce regulated
criteria emissions such as nitrogen oxides and particulate matter,
and cut greenhouse gas emissions. To accomplish this, we needed to
understand how changes in engine design and hardware can impact the
engine combustion processes," said Matthew
Spears, Heavy-Duty Onroad and Nonroad Center Director of
EPA's Office of Transportation and Air Quality. "Using ANSYS
solutions to generate realistic 3-D simulations of internal
combustion engines, we can gain visibility into critical engine
behaviors in a timely, cost-effective manner and obtain accurate
and predictive results to guide the development of our test
engine."
The new fuel standards are part of a joint final rule published
by the EPA and the Department of Transportation's National Highway
Traffic Safety administration (NHTSA). The new standards are
designed to further reduce greenhouse gas emissions and improve
fuel economy for model years 2017 through 2025 for light-duty
vehicles. Combined with the previous EPA and NHTSA standards, the
new program is projected to result in model year 2025 vehicles
emitting one-half of the green gas emissions from the 2010 model
year.
"Designing high performance internal combustion engines that
meet regulatory mandates for reduced emissions is perhaps the top
challenge faced by today's automotive manufacturers," said
Bernie Rosenthal, general manager at
ANSYS. "We are excited to support the EPA as the agency uses our
computer simulation solutions to create its test engine. Reaction
Design's fast, accurate and cost-effective modeling is critical to
developing products that translate reliably to real-world
functionality and lead to new advancements in engine and fuel
technology."
In addition to gaining a better understanding of combustion
dynamics through CFD modeling, the EPA intends to use ANSYS'
detailed soot modeling capabilities to more accurately predict soot
mass and particle size distribution, important metrics in the
standards.
