Development of the Cummins L10 engine to operate on natural gas for heavy duty transit bus applications. Final report, August 1988-December 1991
Abstract
This report covers all of the activities of a program undertaken to develop a natural gas fueled engine using the Cummins L10 diesel engine as the base engine. The base diesel engine is a 10 liter turbocharged jacket water aftercooled carcass that develops 270 hp at 2100 rpm. The design goals included developing a natural gas version at 240 hp with 750 lb-ft of peak torque with exhaust emission level demonstration meeting the 1991 EPA Urban Bus Emission Mandate. Additional goals included demonstrating diesel like vehicle performance and diesel like reliability and durability. Two fuel delivery systems were evaluated, one mechanical and the other electronic closed loop. Field and laboratory test engines were utilized to document reliability. Results of this program led to the production release of the gas engine for transit bus applications and California Air Resources Board certification during 1992.
