Durability Testing of a Natural Gas-Fueled GM 502 CID Mark V Engine. FinalReport, June 1991-January 1994

摘要

This report presents final test results of two near-factory naturally-aspiratedGM 502 cubic inch displacement engines, operated on natural gas fuel. This engine has the potential for use in high output peakshaving or chiller applications. Initially, engine performance was to be measured on both engines, followed by a 1000-hour durability test on the first engine and 500-hour durability test on the second 502 engine. Power, efficiency, blowby, oil consumption, oil degradation, plug erosion, and valve recession were recorded during durability testing. Maintenance was performed as needed and recorded. Results indicate that through proper engineering analysis and design, the naturally-aspirated GM 502 cubic inch displacement natural gas engine could have the potential for use in high output peakshaving or chiller applications.
