Impact of Lube Oil on Advanced Light-Duty CIDI Engine Emissions

摘要

The Partnership for a New Generation of Vehicles (PNGV) has identified the compression-ignition, direct-injection (CIDI) diesel engine as a promising technology in meeting the PNGV goal of an 80-mpg, production prototype, mid-size sedan by 2004. challenges remain in reducing emission levels of the CIDI engine to meet future emissions standards. Techniques under consideration for this project include the use of an alternative fuel (ADMM15) and the use of different lubricants. The objective of this program was to perform an initial screening of three different lubricants to obtain information on their contribution to the particulates emitted by the engine and the potential for emission reduction in a CIDI engine.
