The invention provides a device for improving heat efficiency of an engine and reducing heat load, a water-gas mixing ejector comprises a pipe body and an air injection valve arranged at the lower end of the pipe body, an air pipe and a water pipe are respectively arranged on the pipe body, the periphery of the pipe body is fixedly sleeved on an air cylinder cover, a pressure stabilizing air cavity and a high-pressure water channel are arranged in the pipe body, and the air pipe is communicated with the pressure stabilizing air cavity; an air hole is formed in the middle of the lower end of the pipe body and communicated with the pressure stabilizing air cavity, an air injection valve is sleeved with the air hole, the discharging end of the high-pressure water channel is located on the outer edge of the lower end of the pipe body, and the high-pressure water channel and the air hole do not interfere with each other. According to the device for improving the heat efficiency of the engine and reducing the heat load, the heat load under different working conditions can be restrained through water spraying and water vapor mixture spraying under the high-strengthening working condition test, the heat efficiency is improved through water vapor expansion and combustion phase adjustment, and the heat load is reduced. And support is provided for improvement of the performance of the high-strength diesel engine.
Description
technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a device for improving the thermal efficiency of the engine and reducing the thermal load. Background technique [0002] When the engine is working, the heat load and mechanical load are relatively high, and the combustion temperature in the cylinder is as high as 2000K or more, which causes the heated parts in the cylinder to always face the adverse effects of high heat load. The heated parts in the cylinder mainly rely on the cooling water chamber in the cylinder head, the water jacket or wall surface of the cylinder liner, and the cooling oil chamber of the piston to reduce the temperature in the cylinder. However, as the degree of strengthening continues to increase, the heat load of components is increasing. The temperature of the nose bridge area of the cylinder head and the top surface of the piston of some engines has exceeded the limit o...
