Dresser Waukesha, a manufacturer of natural gas engines, has met the engine efficiency goal of 47% brake thermal efficiency (BTE) established by the U.S. Department of Energy for Phase II of the ARES (Advanced Reciprocating Engine Systems) program.
Dresser Waukesha achieved this efficiency level with a simple cycle 1200 r/min APG1000 lean burn demonstration engine without exhaust energy recovery, according to Jim Zurlo, Ph.D., Dresser Waukesha’s ARES principal investigator. BTE is a technical measure of an engine’s ability to convert the energy in the fuel to mechanical work.
Dresser Waukesha is wrapping up its ARES Phase II activities and looking ahead to Phase III, in which participants will focus on developing an engine system with a 50% BTE.
The ARES program was launched by the Department of Energy in 2001 as a private industry-government partnership to accelerate the development of large natural gas engines that operate with increased efficiency while meeting tight emissions requirements, maintaining current levels of reliability and durability, and reducing ownership costs.
