Diesel Technology
The Diesel
Technology Section in the Engine, Emissions and Vehicle Research Division
performs full-service testing and development on all classes of diesel engines,
fuel injection systems, and engine subsystems, along with exhaust treatment
integration. The group specializes in the characterization and reduction of
gaseous and particulate emissions from diesel engines over various steady-state
and transient test procedures, as well as accommodating special needs of
alternative fuels, unique exhaust treatment schemes, fuel additives, and unusual
applications. The staff is skilled in the application of advanced combustion
with fuel-injection systems and manipulation of EGR in concert with advanced
exhaust treatment. The experience of the section supports the needs of engine
manufacturers, to support and further develop their 2007 and Euro IV (HD)
strategies, explore prototype solutions for the 2010 and Euro V (HD), and
develop Tier II (LD) solutions to meet emission standards.
Skilled in the science of emission measurement, the
group routinely works to develop special test procedures, test cycles, measuring
equipment, and data analysis methods to serve the needs of heavy-duty
on-highway, non-road, passenger car, marine, and locomotive engine
manufacturers, suppliers, refiners, as well as regulatory interests in a
confidential and professional manner.
In addition to working with individual companies, SwRI
can serve the needs of associations (EMA, CRC, MECA) and government (DOE, EPA,
and CARB). SwRI has also formed consortia to support cooperative research
programs, such as the Clean Diesel program that is focused on achieving
heavy-duty engine emission and fuel economy targets through development of
advanced combustion engines. Membership in the Clean Diesel program includes
heavy-duty and light-duty engine manufacturers as well as component suppliers
from around the world.
