Purpose. To radically reduce the cost of the engine; reduce the specific weight and dimensions of the engine; increased efficiency and reliability of the engine; solve the problem of high speeds; solve the problem of high power by developing modular designs.
Scope. Solar energy, distributive energy, cogeneration plants (mini-CHP); heat pumps and powerful environmentally friendly refrigeration units without freon; environmentally friendly charging stations for electric vehicles; vehicles – hybrid or hydrogen cars, submarines, yachts, unmanned aerial vehicles, etc.
Advantages. High environmental friendliness, does not require maintenance or oil change, operates silently on any type of fuel from straw, biogas and any hydrocarbons to solar and nuclear energy.
Technical and economic effect. The universal environmentally friendly engine (UEE) radically reduces the cost of electricity and heat production by 2-3 times.
Description. The essence of the development lies in the deep modernization of the design of the modern Stirling engine (SE), which, as is known, has significant advantages. However, these advantages are devalued by its fundamental disadvantages – high cost, large weight and dimensions and a small range of speeds and powers; To solve these difficult problems, which the world community of specialists could not solve for many decades, the authors conducted large-scale and costly multi-year experiments. The difficulties were associated with the very principle of the engine, which is actually a closed vessel with thick walls under high pressure (up to 250 atm), automatically determining the large weight and size. As a result of the search, all the main units – heat exchangers, body, cylinder, regenerator, piston drive mechanism and control system have undergone radical changes. Thus, the authors managed to create a highly perfect engine – cheap, with acceptable dimensions and weight, economical and reliable. The problem of building high-power engines by increasing the number of 4- and 8-piston modules was also solved. Since the engine operates due to the temperature difference between external heat exchangers (heater and cooler), it can utilize any type of fuel: biogas, combustible waste, household combustible waste, any high-temperature emissions, solar, geothermal and nuclear energy, etc. In addition, it can operate for a long time without maintenance, and it operates almost silently and is more environmentally friendly than any other heat engine. It can also be successfully used at electric vehicle charging stations, as well as in distributed generation systems as cogeneration stations (mini-CHP). Mini-CHPs based on such an engine can produce energy and heat 2-3 times cheaper than traditional CHP or TPP stations.
