Internal combustion engines will continue. Rotary Omega 1 is a new type – light, economical and has virtually zero emissions – VTM.cz

The strong push for transmission electrification does not mean that all efforts to develop internal combustion engines are over. There are also completely new designs, such as the rotary motor Omega 1 From Astron Aerospace, USA. If you associate the word “roundabout”. Wankel engineSo know that this is something completely different.

The Omega 1 promises high performance, compact dimensions, low weight and virtually zero emissions, and will be suitable for motorcycles, cars and airplanes. The motor consists of four rotors divided into pairs. Then each pair is arranged so that the rotors are on top of each other and connected by gears so that they rotate in opposite directions.

The first pair of rotors plays the role of a kind of supercharger, specifically absorbing and compressing the air that is transmitted through the waiting room to the second pair of rotors. The intake air is compressed to 13.7 – 20.7 bar, which is several times higher than that of a conventional turbocharged engine (about 2.4 bar). The second pair of rotors provides combustion of fuel and exhaust.

Astron Aerospace introduces the principle of the Omega-1 rotary engine:

Omega 1 produces about 160 hp and 230 Nm, and the maximum is 25,000 rpm. Despite all this, the engine weighs only 16 kg (a powerful classic engine weighs several times more). These rotary units can be combined into larger units, then the outputs are added (the Omega double has 320 hp, 460 Nm and weighs 31.8 kg).

What interest?

Economical operation is made almost without emissions (the manufacturer does not specify specific values), among other things, with a simpler design that leaves little room for losses. In a conventional internal combustion engine there are losses, for example, during valve operation, friction of parts with each other, cooling, etc. Omega 1 is air cooled, requires minimal lubrication, and the only moving parts are rotating elements.

Fuel consumption is further reduced by the “skip fire” function, which can be loosely translated as skip ignition or combustion. It is essentially similar to cylinder deactivation in conventional internal combustion engines. When the engine is on high gear, Omega 1 ignites the mixture every cycle. With lower performance requirements, combustion occurs only as needed, up to every tenth cycle.

The manufacturer compares the simplicity of the engine with the sophistication of a single-cylinder four-stroke lawn mower. With its simple design, Omega 1 should be low profile and cheap to maintain, and engine overhaul should be required no later than 100,000 hours of operation.

Asteron Aerospace pledges on its website that licenses to use the technology are extremely cheap. In addition, the manufacturer is proud that it has signed a contract with a supplier from the US Department of Defense, so it will begin to supply engines to the US government.

It looks great, so we just have to wait for the first real deployment and the first potential problems. Based on the information currently available, what do you think of the future of internal combustion engines?
