Development of a light-duty gas engine for cogeneration service. Annual report, March 1985-May 1986

OSTI ID:5988351
This report covers the first year's activities of a program undertaken to improve the performance and maintenance requirements of a light-duty gas engine for cogeneration service. The subject engine is a 454-cubic-inch displacement automotive gasoline engine converted to operate on natural gas. This engine is currently used in cogeneration applications. It is the object of the program to improve its performance, both in terms of output and efficiency, and to reduce its service requirements, thereby enhancing gas-fired cogeneration applications. Results of the first year's efforts indicate the potential for operating the engine at a rating of 75 kW (vs its 60 kW current rating) with an efficiency improvement of 8%. These improvements were achieved through camshaft optimization and increased compression ratio. A 75-kW engine is currently being endurance tested. Work on extension of the service interval is focused on the oil change interval. The effects of sump size, oil type, type of filtration, fuel/air ratio, etc. are reported.
