A revolutionary rotary engine could be the future of ICEs: it’s called Omega 1
Manufacturers are investing time and money in the now inevitable transition to electric propulsion, but there is a company that designed a revolutionary engine that could prevent the end of the era of internal combustion engines. It’s called Omega 1, and it’s a rotary engine that promises sparks.
Astron Aerospace, that’s the name of the company that produces it, strongly believes in this project, which guarantees performance, low emissions and efficiency, especially efficiency. An ICE (Internal Combustion Engine, discover all the terms and abbreviations in our Glossary of electric mobility) in fact suffers many losses due to friction resulting from the movement of the pistons, from the heat and from the combustion process itself.
The Omega 1 was invented by Matthew Riley and is a rotary engine similar to Mazda’s famous Wankel, but it works very differently, and it also solves one of the problems that plagues it, which is throttle overlap. ‘exhaust. L’Omega 1 is indeed built in such a way that the classic 4-stroke cycle is divided into two separating cold air from hot air: one half of the engine is made up of two bladed rotors which take care of the intake and compression of the air, while the other half manages the combustion and the ‘exhaust.
The engine therefore has 4 rotors mounted on two shafts, which rotate in unison. Looking at the pictures, the light blue color pair handles the intake and combustion, while the red one handles the combustion and exhaust. The rotors are coupled to synchronizing gears which allow them to rotate in opposite directions with the same speed. These gears and their bearings are the only contact elements inside the motor, and the only ones that require lubrication. Any engine however, it requires incredibly precise tolerances as there are no joints, but the company points out that with the extremely high rotational speeds obtained, “there is not enough time for the air to escape during operation”. And by super high, we mean 25,000 rpm.
Running it will also keep fuel emissions low, as during acceleration the engine will burn fuel with every rotation, but in the cruising phases, combustion will only take place when necessaryevery 5, 10 or 50 rotations.
Moreover, it is an incredibly small and light engine (it weighs only 15 kg), but it delivers 160 hp and 170 Nm of torque, with a speed that varies from 1000 to 25000 rpm. Moreover, given its structure, can be daisy chained for more performancetherefore two coupled motors would bring the power to 320 hp and 340 Nm of torque with a weight of just 30 kg.
Aston Aerospace said the engine could be used as a generator, or as a marine, aerospace and of course also on cars, and in the latter case it would prevent, or delay, the demise of heat engines. You just have to wait for a real application of the engine to see it at work.
