1. EcoMotors is developing high-efficiency engines — specifically the unique opoc (Opposed Piston Opposed Cylinder) engine — for use in cars, light trucks, marine applications, agricultural vehicles, ...

This pushes the pistons out, and the cycle repeats itself. This all results in an engine that is small, power dense, and quite efficient.

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.

Opposed-piston engine technology has been touted as a possible alternative to conventional engine designs for years. Now, opposed-piston engine developer Achates Power reports that its 10.6L ...

Together the three recipients will invest another $4 million to develop a 3-cylinder, 3-liter opposed-piston gasoline compression engine that could improve fuel efficiency by 50 percent or more on ...

Radical new engines make a run at reality in the F-150 Achates' highly efficient opposed piston engine is set to find a home in the Ford. Brian Cooley explains what makes it special.

EcoMotors International's opposed-piston engine on the other hand might well have a future, as the company has just announced a $200 million deal to build its engines in China.

Together, the three recipients will invest another $4 million to develop a three-cylinder, 3-liter opposed-piston gasoline compression engine that could improve fuel efficiency by 50 percent or ...

In a closed-cycle simulation, they found that the 4-stroke (4S) showed an indicated thermal efficiency (ηfuel) of 47.5%; the opposed-piston 4-stroke (OP4S), 50.1%; and the opposed-piston 2-stroke ...

That’s why I was so excited when I heard that INNengine of Granada, Spain had produced a opposed-piston engine that packed a pretty powerful punch in an extremely tiny package.

Together the three recipients will invest another $4 million to develop a 3-cylinder, 3-liter opposed-piston gasoline compression engine that could improve fuel efficiency by 50% or more on large ...
