Greencarcongress – Achates Power, the developer a two-stroke, compression-ignition (CI) opposed-piston (OP) engine, is presenting performance and emissions results of the Achates engine used in a ...

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.

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, ...

David Johnson, president and CEO, Achates Power, said: “Light trucks representing 41% of sales use 55% of the fuel use and emissions because they’re driven more miles per year and their fuel economy ...

A pair of heavy-duty opposed-piston engines will be produced for an emissions-reduction project in California, officials with the program announced Nov. 8 at a press event in San Diego. The two 10 ...

Four piston engine Monolith Engines has developed a set of dual (Fig. 1) and quad (Fig. 2) opposed piston engines (watch Two and Four Cylinder Single Stroke Opposed Piston Engines on Engineering TV).

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

Opposed-piston engines were invented in the early 1900s and probably are best known for powering Junkers airplanes in Germany. They also have been used in maritime applications.

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