An opposed-piston engine is a piston engine in which each cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used, mostly in large scale applications such as ships, military tanks and in factories.
Two-Stroke Diesel Engine. The engineers and scientists started Achates Power in 2004 with the audacious idea that innovation and modern technology could transform the proven and record-setting two-stroke opposed-piston engines of the past into the clean and efficient engines of the future.
James Atkinson, whose name adorns many of today's high-efficiency engines, originated his cycle on an opposed-piston engine in 1882, but the idea really gained traction in the '30s and '40s, when ...
The Achates Power opposed-piston engine is packed full of unique technology. The supercharged, turbocharged, diesel 3 cylinder makes use of six pistons, two of which operate in each cylinder.
The Fairbanks-Morse 38 8-1/8 is a diesel engine of the two-stroke, opposed-piston type. It was developed in the 1930s, and is similar in arrangement to a contemporary series of German Junkers aircraft diesels. The engine was used extensively in US diesel electric submarines of the 1940s and 1950s, as backup power on most US nuclear submarines, as well as in other marine applications ...
Most automotive engines below class 7 or and 8 use engine blocks without liners so use of liners in opposed piston engines will add costs. A liner-less opposed piston engine block with cast bores and all passages cast in through use of a printed block molds or by printed construction or additive manufacturing might be a future option.
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.
And, Fromm points out, opposed-piston engines are inherently smooth, so a single-cylinder, two-piston version could make an ideal range extender for a PHEV, especially since it can be made into a ...
The OPOC engine is an opposed-piston opposed-cylinder, 2-stroke engine. It consists of two cylinders with a piston at both ends. It has no cylinder head, so there are no valves. Each piston travels about half the distance of a cylinder in a conventional engine. As compared to other conventional engines, the OPOC has drastically small size.
