Energy-saving environment-friendly engine

Abstract

The invention discloses an energy-saving environment-friendly engine. The serious internal resistance phenomenon of a traditional crankshaft engine is eliminated, and meanwhile high-temperature heat energy generated by violent combustion of fuel in a combustion chamber is utilized for generating ultra-supercritical superstrong steam power at the temperature of 600 DEG C or above. The engine is mainly composed of an impeller, a fuel gas direct injection cylinder (16), an ultra-supercritical steam injection cylinder (18), a high temperature resisting thermal radiation diversion isolating sheet or high temperature resisting flame jet flow separation plate, a two-gas combined main heating and stress applying chamber and the like. Due to the fact that the interior of the ultra-supercritical steam injection cylinder of the engine can be heated by a wide and long high-temperature thermal radiation sheet above the fuel gas direct injection cylinder, or high-temperature flames ranging from 1,000 DEG C to 2,000 DEG C below the high temperature flame jet separation plate are directly jet into the ultra-supercritical steam injection cylinder of the engine for heating, especially huge ultra-supercritical steam power larger than that of traditional crankshaft piston type engines by 10-60 times is generated, and great and large-proportion energy saving and great and large-proportion power lifting better than those of all the traditional crankshaft piston type engines are thoroughly achieved.

AI Technical Summary

Problems solved by technology

[0002] 1. The traditional crankshaft piston internal combustion engine, 1 has serious internal friction resistance phenomenon, 2 has "angle" dispersion phenomenon, 3 has energy self-consumption phenomenon such as "dead point" offset phenomenon, 4 traditional crankshaft piston engine needs The heat energy generated by fuel combustion is wasted through water cooling or air cooling, especially through exhaust emissions, so the traditional crankshaft piston engine has serious energy waste

[0003] 2. The traditional gas turbine is also a single-combustion internal combustion engine, and the fuel is only burned in the cylinder. The temperature of the cylinder surface and the heat energy generated by the exhaust gas also waste most of the heat energy generated.

[0004] 3. The traditional steam engine is an external combustion engine, and the fuel is burned outside the cylinder, which wastes more energy than the internal combustion engine. In addition, the steam temperature used by the traditional steam engine is low-temperature and low-pressure power steam below 374°C, and the power generated by unit energy consumption is very small. , a huge waste of energy

[0005] 4. The ultra-supercritical firepower engine unit is also a giant, with a wide area, many supporting facilities, and a huge investment in a single machine. Moreover, the temperature of the power steam is difficult to exceed 700°C, and the special advantages of steam cannot be fully and comprehensively brought out. , so a greater power cannot be developed, and the power increase is close to the limit
