Silent combustion engine

The rotary piston engine (Wankel engine) consists, as a rule, of exactly the same sections. In each of these sections, 1 to 8, 16 or even more thermodynamic cycles can be performed per revolution, depending on the operating mode and configuration of the used section (for reference, in a traditional 4-cylinder combustion engine, only two thermodynamic cycles are performed per revolution). The engine is compact and lightweight. It is practically silent and vibration-free, which is crucial in today’s environment where the background noise level is extremely high. The low noise level is due to the absence of exhaust bypass valves in the engine and the fact that any pressure can be set in the combustion chambers at the moment of gas exhaust, including that close to atmospheric pressure and even below. Like no other known engine, the Wankel engine features a large adjustable torque and large adjustable power at low revolutions, which eliminates the need for additional use of reducers (gearboxes).

The engine features active air cooling, combined with a gas exhaust system, and does not require additional liquid cooling system, radiators, etc. The issue of lubrication of interacting power and other engine elements is solved quite simply and efficiently. First of all, there are no rubbing elements in the engine, between which big contact tensions would occur. Secondly, all interacting elements are lubricated in the compartment of the annular chamber, where the pressure close to atmospheric pressure is constantly maintained via an air vent. The engine is cost-efficient, reliable and well adapted to ceramics. Rotating main (working) shafts of adjacent sections of the engine are connected with each other by ordinary couplings, which allows the use of different types of sections and their combinations in one engine. The presented model provides the unique possibility of complete disconnection of individual sections from the running engine (from the rotating shaft). As a result, you can use sections with differently directed torques alternately, i.e. not simultaneously, in one engine.

The engine is easy to unify. It is enough to master the production of only four or five standard sizes of sections to cover the entire range of technical characteristics of engines used in modern vehicles, from small cars to heavy mining and construction equipment, ships and aircraft.
