Title: Collaborative lubricating oil study on emissions (CLOSE)

Principal Investigator / Author(s): Bogdanoff, Michael

Contractor: South Coast Air Quality Management District

Contract Number: 06-324

Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels


The Department of Emissions Research and Development of Southwest Research Institute (SwRI), in conjunction with the Desert Research Institute (DRI), performed this project in response to National Renewable Energy Laboratory (NREL) Request for Proposal (RFP) Number REV-6-66409, “Investigation of the Role of Lubricating Oil on Particulate Matter Emissions from Vehicles” under Subcontract Number AEV-7-66409-1, SwRI Project No. 03.13012. In addition, the Coordinating Research Council (CRC) augmented this study‟s funding under CRC Project No. AVFL-14 “Effect of Fuel and Lubricant Composition on the Emission of Vehicles, SwRI Project No. 03.13029. The program consisted of extensive chemical and physical characterizations of particulate matter (PM) emissions from a limited number of gasoline-, diesel- and natural gas-fueled vehicles operating on fresh and aged crankcase lubricants in an effort to evaluate the relative contributions of fuels and crankcase lubricants on PM and SVOC emissions from vehicles.
