Frost & Sullivan Selects Achates Power for Product Innovation Award
 

Achates Power was recently selected as Frost & Sullivan's 2013 North American New Product Innovation Award winner in the medium- and heavy-duty commercial vehicle engine market.

"Strong, fundamental research and advanced engineering have enabled Achates Power to develop more than 1,000 unique engine innovations. It's these innovations that have produced a clean, significantly more fuel-efficient, opposed-piston, two-stroke engine that holds the potential for application in several medium- and heavy-duty commercial vehicle applications," said Sandeep Kar, global director of Commercial Vehicle Research, Frost & Sullivan. "With the volatility of fuel prices and the strengthening of global emissions regulations, the Achates Power engine is well-positioned for commercialization and growing market penetration."

David Johnson, Achates Power president and CEO, accepted the award at a ceremony in San Diego on March 12. 
 

Frost & Sullivan Best Practices Awards recognize companies in a variety of regional and global markets for demonstrating outstanding achievement and superior performance in areas such as leadership, technological innovation, customer service and strategic product development.
 

Oil Consumption in an OP2S Engine
 

Opposed-piston, two-stroke (OP2S) engines have been around since the late 1800s and were once widely used in ground, marine and aviation applications. However, with the advent of global emissions standards, production of these engines for on-road use was halted. Why? Despite the many advancements made to two-stroke powertrains, the OP2S engines of the 1970s suffered from high NOx and soot emissions and high oil consumption. Using the latest engineering methods and technologies, Achates Power has overcome these challenges and demonstrated less than 0.1% fuel-specific oil consumption. Watch the video to find out how we accurately measure and maintain low oil consumption in our OP2S engine.

There are a number of factors that contribute to the inherent thermal efficiency of the opposed-piston engine. Often, however, turbocharger efficiency is an overlooked and underappreciated advantage of opposed-piston, two-stroke engines like ours. Due to the two-stroke cycle, the OP2S has a natural fit to the high efficiency points of a turbocharger's compressor map. Read more.
