Achates Power to present fuel efficiency results of its two-stroke opposed piston engine at SAE 2011 Commercial Vehicle Engineering Congress
Achates Power, the developer of a two-stroke, compression-ignition (CI) opposed-piston (OP) engine (earlier post), will detail the Achates Power two-stroke opposed-piston (OP) engine architecture and reveal its performance and emissions results in a medium-duty application in a paper to be presented at SAE the 2011 Commercial Vehicle Engineering Congress (paper 2011-01-2221).
During his presentation, CEO David Johnson will discuss OP engine advantages and challenges, describe methods used to leverage the advantages and minimize challenges, highlight test and analytical methods, and provide cost, weight and complexity reductions of the engine.
Highlights include testing, analysis and results that conclude the Achates Power engine:
is more efficient, demonstrating a fuel efficiency improvement by more than 19% compared to today’s best diesel engines;
is clean, with engine-out emissions that are compatible with current and future standards; and
reduces costs, weight and overall complexity of the engine with 40% fewer parts due to elimination of the cylinder head and valvetrain
During the same session, Dr. Randy Herold, Achates Power senior staff engineer, will present the thermodynamic benefits of opposed-piston two-stroke engines (paper 2011-01-2216).
The SAE ComVEC is the first of several conferences this fall where Achates Power executives will present their demonstrated results. Achates Power will also speak at the upcoming Der Arbeitsprozess des Verbrennungsmotors (Working Process of the Internal Combustion Engine), ASME Internal Combustion Engine Fall Technical Conference, and Directions in Engine-Efficiency and Emissions Research (DEER) Conference.
