新型无连杆二冲程航空活塞发动机结构分析

Structure Research of Two-stroke Aviation Piston Engine without Connecting Rod

为了开发出一种无曲柄连杆机构的大缸径二冲程点燃式活塞发动机,参考国外设计专利,运用三维CAD软件构建发动机概念电子样机,分析发动机结构与工作原理。结果表明:新型大缸径无连杆发动机结构能满足航空活塞发动机高效率、高功重比的需求,具备较高的应用价值。

In order to design a new kind of two-stroke spark ignition internal combustion engine with a large bore and non-connecting rod, the foreign design patent was referred, the CAD software was applied to construct the engine concept model, and the structures and the work process of the engine were analyzed. As a result, the structure of the new kind of engine with large bore and non-connecting rod satisfied aeronautic piston engines by high heat efficiency and high power/weight ratio. Above all, the new kind of engine deserves a further research.
