October 19, 2012 The Virtual Driver	An Engine in Opposition to Convention David Johnson has an enviable résumé. He launched an all-new diesel in Ford's Super Duty pickup before heading to GM where he worked on clean diesel programs for Opel, Saab and Renault passenger vehicles. Navistar was next. There he was program manager for the MaxxPro line of Mine-Resistant Ambush-Protected (MRAP) vehicles used in Iraq and Afghanistan, before becoming vice president of product operations for military and export markets. In 2008, he went to Achates (a-kay-tees) Power as president and CEO, and was given the task of using that experience to accelerate the development of an opposed-piston two-stroke diesel engine. These engines were prevalent in the early part of the 20th century, but fell afoul of shortcomings like high hydrocarbon emissions and heavy oil consumption as that century progressed. However, until their deficits outweighed their plusses, opposed-piston two-strokes were more efficient than conventional piston motors.
September 13, 2012 Mother Nature Network	Amazing Engines Promise 60 to 100 mpg The two-stroke motor isn't new—in fact, there's probably one in your weed whacker. But Achates Power and other companies say they can turn around its image as a big polluter. It would be a mistake to count out the internal-combustion engine as yesterday's technology, soon to expire in a puff of exhaust gas. Electrification is coming, but meanwhile engineers have offered more innovation for the venerable gas engine in the last three years than they did in the previous 20. The result is 40 mpg on the highway, from four-cylinder power plants with the same performance as older V-6s or even V-8s.
August 7, 2012 Automotive Engineering International	Advances in Simulation Deliver Better Engines Engine developers need to deliver cleaner engines that burn less fuel, are more durable, and quieter.

February 2012 Diesel Power Magazine	Radical New Diesel Ideas . . .Although opposed-piston engines (OPE) are radical to the consumer world today, they are not new since the first versions were in operation more than a century ago. OPEs use two pistons in one cylinder and require no head gaskets. The two-stroke compression-ignition design of Achates Power uses ports in the cylinder wall instead of a valvetrain to control intake and exhaust flow. This company presented the oil consumption, emission, and performance results from its 53 percent thermal-efficient engine at the DEER conference. It looks like its three-cylinder design will outpower the 6- and 8-cylinder engines we use and love today.
January 24, 2012 IndustryWeek	Viewpoint: To Tackle the World's Energy Problems, We Need to Make All Engine Technologies More Efficient There is no one solution to address the issues facing the transportation industry.

July 5, 2011 GigaOM Cleantech	Why the days of the internal combustion engine are NOT over Here's some sobering news out of the raucous fourth of July weekend: considering battery prices and $4.50 per gallon gasoline, it'll take a little under 6 years for a hybrid car to pay off in fuel savings, and 8 years for an electric car, according to this report in the Wall Street Journal. At that rate of battery innovation, and if gas prices don't climb, then plug-in cars will remain largely financially not viable for most buyers in the U.S. for years to come. That's not good news for electric car makers, but could actually be a driver for companies building new, more efficient, internal combustion engine technology...Other companies that I've covered that are developing more efficient engines include Pinnacle Engines, which makes a four-stroke engine that it says can deliver 30 to 50 percent better fuel economy, and could be commercialized by 2013. Another is Achates Power, which is building a closed piston, 2-stroke engine that gets 10 to 15 percent better fuel economy than state of the art diesel engines that exist today.
