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, ...

In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single opposed-piston engine. This unique project improves balance, reduces vibrations, and ...

Achates Power’s heavy-duty opposed-piston diesel engine is capable of meeting CARB’s 2027 regulation.

Opposed-piston opposed-cylinder engines are scalable, have been created in several different displacements, and can be stacked together like Legos to build modular powerplants.

Ever heard about opposed piston engines? It's a concept often used to manufacture large locomotive and marine engines, where two pistons face each other and share the same combustion space ...

Instead of one piston per cylinder, which requires four cycles per firing, opposed-pistons engines have two pistons per cylinder, both connected by levers with a single crankshaft.

The opposed piston concept goes back to WWII. Junkers, the plane manufacturer of the Third Reich, developed a somewhat unsuccessful opposed piston diesel engines for planes back in the 1930s.

Cars 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.

Instead of one piston per cylinder, which requires four cycles per firing, opposed-pistons engines have two pistons per cylinder, both connected by levers with a single crankshaft.

The Achates Power Opposed-Piston Two-Stroke Engine: Performance and Emissions Results in a Medium-Duty Application (2011) Historically, the opposed-piston two-stroke diesel engine set combined records ...

Opposed-piston advocates say that the engines can use many of the same parts, materials and tooling as today's internal combustion engines -- a piston's a piston, in other words.

Instead of one piston per cylinder, which requires four cycles per firing, opposed-pistons engines have two pistons per cylinder, both connected by levers with a single crankshaft.
