SwRI Information

Home

The combination of superior fuel economy and durability has made diesel engines popular worldwide. Because these engines can emit large amounts of ozone-forming constituents and particulates, they are subject to increasingly stringent regulations that require continual improvements in the combustion process. Southwest Research Institute (SwRI) engineers and technicians help engine manufacturers and suppliers meet these regulations and emissions standards.

Diesel engine combustion research at SwRI includes full-service evaluation and development on all classes of:

• Diesel engines

• Fuel injection systems

• Engine subsystems

Diesel Engine Combustion Research Services

A comprehensive range of services are available, including:

• Combustion research

• Diagnostic evaluation

• Engine evaluation

• Modeling and design

• Rating development

• Cold-start development

• Combustion chamber designs

• Variable-rate fuel injection systems

• Advanced turbocharging concepts

• Diluents, such as exhaust gas recirculation or water injection

• Electronic control system development

• Model-based control

• Variable valve timing strategies

• Aftertreatment integration

• Fuel property evaluation

• Homogeneous charge compression ignition (HCCI)

Gaseous and Particulate Emissions Research

The group specializes in reducing gaseous and particulate emissions from diesel engines over various cycles by:

• Applying advanced engine-based technology

• Designing novel combustion systems and fuel-injection systems

• Using diluents such as exhaust gas recirculation or water injection

SwRI supports engine manufacturers as they finalize their 2002/2004 and Euro IV (HD) strategies and plan for the 2007 and Euro V (HD) and Tier II (LD) emission standards.

Experienced SwRI staff improve diesel combustion and reduce emissions caused by light-duty, medium-duty, and heavy-duty engine applications including:

• On-highway

• Off-highway

• Marine

• Stationary

• Locomotive

Clean Diesel V Program

SwRI also conducts the Clean Diesel V program, a 4-year, annually renewable, cooperative research program targeting engine-out emissions of NOx + NMHC = 0.2 g/hp-hr and PM = 0.01 g/hp-hr. Membership in the Clean Diesel V program includes manufacturers of heavy-duty and light-duty engines and component suppliers from around the world.

Internal Research and Development

Internal research and development (IR&D) is performed at SwRI to gain expertise in new areas and to develop skills needed by our clients. IR&D project results are usually presented to clients in both public and private forums. A list of 2008 IR&D projects is available.
