Development of the Dresser Waukesha 16V150LTD Engine for Bio-Gas Fuels

Dresser Waukesha released the 16V150LTD engine for operation on pipeline natural gas in 2006. The engine has since been developed for operation on low Btu Bio gas fuels; including landfill and digester applications for both 50 and 60 Hz operation. This paper discusses the development of the engine fuel system, calibration changes, and test results of the Bio-gas 16V150LTD. Fuel system modifications were made for the higher fuel flow rates and calibration changes were necessary to meet performance requirements across the heating value range. Test results are presented which discuss the effects of the lower heating value bio-gas fuels on combustion and engine performance.
