Features and Performance Data of Cooper-Bessemer Coal-Fueled Six-Cylinder LSB Engine

Abstract

The six-cylinder Cooper-Bessemer LSB engine has been converted to operate with one cylinder on coal-water slurry (CWS) fuel and with five cylinders operating on diesel fuel. This development followed the successful operation of the single-cylinder JS engine on CWS for over 600 hours to date. The CWS injection system was scaled up about a factor of two in fuel volume from the JS system. A new cam box drive was fabricated for the LSB single-cylinder operation. The engine was operated and full power output was achieved from the CWS cylinder. Preliminary test results indicate good operate efficiency. An exhaust emission control system is in place for the proposed operation of all the six cylinders on CWS and major engine components are on hand. These results mark a significant milestone in the progress toward commercial readiness of the coal-fueled diesel engine system.
