Advanced Engine Fluids (AEF) Consortium

Engine technology is changing so rapidly that the demands placed on the fuel and lubricant performance are evolving quickly. The Advanced Engine Fluids (AEF) consortium will continue the research and development work begun in the Pre-Ignition Prevention Program (P3) to expand into other critical areas for the engine and petroleum industries. This new program will investigate how fuel and lubricant chemistry affects engine combustion and vice versa.

Main Areas of Concentration

The AEF consortium will research the impact of fuels and lubricants on engine combustion and the requirements needed for optimizing future engine technologies. The research will focus on ways to accelerate improvements for fuels and lubricants to keep up with emerging fuel economy standards. SwRI’s decades-long experience in fuels and lubricant testing combined with our industry-leading research on advanced engines gives us unique insight into the challenges facing modern fuel and lubricant companies.

Program Task Areas

The initial task areas are detailed below. Since the AEF consortium is a continuously evolving research program, the distribution of effort for these areas will vary based on budget, client direction, and research findings.

Topic areas for the AEF consortium
