Achates Power to Present Fuel Efficiency Results of its Two-Stroke Opposed Piston Engine at SAE 2011 Commercial Vehicle Engineering Congress +VIDEO

SAN DIEGO – September 6, 2011: Achates Power, developer of radically improved internal combustion engines that enhance fuel economy, reduce greenhouse gas emissions and are lower cost, will discuss engine fuel efficiency challenges and improvements at the SAE 2011 Commercial Vehicle Engineering Congress (ComVEC) Sept. 13-14 at the Donald E. Stephens Convention Center in Rosemont, Ill.

In a paper presentation on Sept. 14, CEO David Johnson will detail the Achates Power two-stroke opposed-piston (OP) engine architecture and reveal its performance and emissions results in a medium-duty application (paper 2011-01-2221). During his presentation, 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 percent 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 percent 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).

Achates Power draws on the engineering and analytical expertise of its more than 50 in-house engineers and scientists, state-of-the-art laboratory facilities utilizing industry-leading testing, simulation and analysis tools, and its 2,000-plus engine test hours to develop innovations in all areas of engine design, which are covered by more than 50 patents and patent applications.

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.
