What it has developed is an opposed-piston, two-cycle ... In fact, these engines have successfully powered things like ships, tanks, and aircraft. But to date, this technology has never really ...

This is a weird engine, with two opposed pistons in one cylinder that come very close to slamming together. It’s a great design for aircraft engines due to it’s lightweight construction.

While most engines made in the last 100 years have adhered to the standard single-piston per-cylinder design, the TS3, also known as the "Commer Knocker," is an exception. The opposed-piston ...

And that's just one route. Another is the EcoMotors International (EM) opoc engine, aka open piston, opposed cylinder. Here's how it works. Instead of an I or a V pattern, EM's opoc is laid out ...

and Stationair are powered by piston engines. These are 4- to 6-cylinder direct drive horizontally opposed, air-cooled engines. Depending on the aircraft requirements, these engines may be ...

Fuelled by hydrogen, or by sustainable aviation fuel, these novel engines promise unparalleled thermal efficiency and the flexibility for climate-friendly operations including con ...
