Internal research (IR) is conducted by Southwest Research Institute (SwRI) to gain expertise in new areas and to develop skills needed by our clients. IR project results are usually presented to clients in both public and private forums. Below is a partial list of IR projects related to spark ignition (SI) engines. Please contact us if you would like additional information on any of these topics.

• Fuel Wall Interactions Within the Cylinder of DI SI Engines, 03-R9166, October 1999—Current

• Engine Wear Trending Using Radioactive Tracer Technology, 03-9126, April 1999—July 1999

• Modeling Combustion and Emissions in Diesel and SI Engines, 03-9038, April 1999—September 1999

• Determination of the Effect of Water on Soot Formation, 03-R9073, April 1998—October 1999
