重油航空活塞发动机燃油喷射技术

Fuel injection technology is one of the key technologies of aviation piston engines. Its structure and characteristics directly affect the integral performance of aircraft piston engines. With the requirements of general aviation for better engine performance, the development of fuel injection technology continues. This paper summarizes the current fuel supply systems used in various heavy fuel aircraft piston engines, sorts out the classic models that are applicable to them, and reviews the advantages and disadvantages of the various fuel supply systems. It expounds some cutting-edge theories, simulation calculations and experimental methods used in the study of heavy oil injection technology, and analyzes some difficulties in heavy fuel atomization, followed by relevant suggestions for the study of heavy fuel injection technology. Finally, this paper puts forward some ideas and key technologies for the future development of heavy fuel aircraft piston engine, with a focus on providing technical guidance for the forward development of heavy fuel aircraft piston engines, thus contributing to the sustainable development of China’s general aviation.
