Diesel Technology Section

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.
