Opposed Piston Engines Poised for Launch in the Next Five Years
The two-stroke opposed piston engines that were first developed in the 1930s previously failed to catch on in the automotive market. However, with the opportunities afforded by modern technology, powertrain developers are revisiting old designs and updating them to compete with the more conventional internal combustion engine (ICE) architectures to which OEMs are accustomed today.

Fuel Smarts: Opposed-Piston Diesels About Five Years Away
Truck users can look forward to 30% better fuel economy at 10% lower production cost, says Achates Power
Security’s tight at Achates Power Inc. in San Diego, where you don’t just walk into the light-industrial building and expect a tour of the labs — something common where R&D is under way. Before getting beyond the lobby, I had to prove that I’m an American citizen by showing my USA-issued passport.

One of Achates’ clients is the U.S. Army, which has the company’s engineers working on an opposed-piston engine design for possible use in a Hummer-like light/medium-duty utility truck. The military consumes huge quantities of fuel, and much of that has been in distant war zones, like Afghanistan, where fuel has to be shipped in at great expense. It believes the OP engine may be an answer.

In era of giant suppliers, startups are winning auto business
You may have seen Mark Shaw by now. On morning TV. In YouTube videos. At auto events. Explaining his proposed new auto technology in a TED Talks lecture. Shaw is the guy who dumps mud, chocolate syrup, motor oil and paint onto the hood of a car to demonstrate how his "self-cleaning car paint" lets the mess roll off like it was never there. In demonstrations worthy of late-night TV spots, Shaw is trying to do the same thing countless entrepreneurs have done since the days of Henry Ford -- get a foot in the door of the rich auto industry.

Achates Aims at 2025 Light-Truck Power
It's autumn 2024, and you're at the local auto mall shopping for a new pickup truck—one that delivers the 32-mpg fuel economy required of full-size trucks for the upcoming model year. As the salesperson lifts a hood to show off the engine underneath, she proudly declares "2.25 liters" and you see what appears to be a supercharged SOHC inline four nestled neatly within the engine bay. . .The engine in question is the OP2S—opposed-piston two-stroke—an advanced compression-ignition unit that has its roots in 1930s aero, marine and military vehicle propulsion, where its inherent reliability, fuel efficiency, and smooth operating characteristics were proven. And for the past decade, Achates Power, a San Diego-based engine and combustion-technology company, has been re-inventing the OP2S, transforming it into a viable candidate to power future light trucks and other applications.

2014 SAE Show Future Tech Roundup:
Everybody's Trying to Help the OE Manufacturers Meet 54.5-MPG CAFE

With the DOT/EPA 54.5-mpg CAFE mandate looming just 11 years off, it’s no surprise that a majority of the booths at the 2014 SAE show—at least of the ones that caught my eye—aimed to entice weary OE engineers with better fuel-saving mousetraps. . . Achates is proposing a two-stroke three-cylinder six-piston design, which stands on end to fit easily in the package space of a typical I-4 or V-6 engine. The Achates gang reckons the opposed piston idea is ideal for a two-stroke because the cylinder’s surface-area-to-volume area during combustion is less, reducing heat losses. . . Extensive computer modeling suggests that this engine would be 30 percent more fuel efficient than an experimental Cummins ATLAS 2.8-liter turbodiesel in a Nissan Titan pickup of nearly equal power output (200 hp/369 lb-ft). The Achates concept is headed for production, first in heavy stationary power-generation or ship applications.

Dubbed "An Engine That Uses One-Third Less Fuel" in MIT Technology Review (Jan. 14, 2013, TechnologyReview.com), Achates’ engine bypasses the need for cylinder heads, "which are a major contributor to heat losses in conventional engines," according to the company. The OPE contains two pistons per cylinder, working in opposite reciprocating action. In a paper authored by Achates’ staff, the company states that its opposed-piston, two-stroke diesel engine design "provides a step-function improvement in brake thermal efficiency compared to conventional engines while meeting the most stringent, mandated emissions requirements."

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.

So it was appropriate to hear from the CEO of Achates Power, which has emerged as one of three prominent developers of opposed-piston engines.

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. Electric vehicles are a viable solution for some consumers and industries, but they will not be a panacea. Significant improvements across a range of transportation technologies are necessary in light of dwindling petroleum reserves and global warming concerns. The industry debate is currently centered on whether hybrid and electric vehicles are the wave of the future. But only focusing the discussion on one or few solutions is missing the opportunity, the bigger picture—and the point.

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.
