Developers from Belgorod State Technological University named after V.G. Shukhov presented a scheme for an unusual connecting rod-less rotary engine with a simplified design and increased reliability. The solution is aimed at transport and industry, where resource and operational stability are critical.
No pistons in the power unit
The main difference is the rejection of pistons and connecting rods. Inside the rotor, a block of three plates operates, forming intake, compression, power stroke, and exhaust chambers.
They move along T-shaped curved grooves and replace the classic gas distribution mechanism. This reduces the number of components and potential failures.
Lower fuel consumption
According to the developers, the new scheme reduces fuel losses during scavenging and increases service life due to a simpler design.
Increasing the duration of the power stroke directly increases the smoothness and reliability of the engine.
Engineers also changed the cycle kinematics. Now the power stroke occupies up to 1/3 of the full cycle, compared to 1/4 in a classic ICE, which increases rotational uniformity and reduces vibrations.
The flywheel further stabilizes operation, and seals ensure chamber tightness.
Where it can be used
The technology is being considered for ground, water, and air transport, as well as for industrial drives.
But the key question remains open — can the connecting rod-less rotary engine go beyond experimental solutions and compete with classic ICEs in mass production?
There, not only the scheme, but also the resource, efficiency, and operating costs become decisive.
