摘要：
Based on the analysis of the development status of aviation heavy fuel piston engines at home and abroad, the core technical indexes of engines with different power levels were obtained by comparing and analyzing the existing mature models, and the important significance of developing aviation heavy fuel piston engines in China was put forward. According to the power level, the technical path of the development of aviation heavy fuel piston engine was analyzed, the technical difficulties faced by the heavy fuel engine with high power-to-weight ratio were summarized, and the key technologies of the spark-ignition aviation heavy fuel piston engine, namely, the rapid atomization technology, the rapid cold start technology, the knock suppression technology and the high-altitude supercharging power recovery technology of heavy fuel, were presented. A breakthrough over the above key technologies will be of great significance to the development of aviation heavy fuel piston engine technology. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
