阐述165F柴油机扩缸变型的指导思想:对曲轴、机体、主轴承等主要零件强度进行分析:为了有效地控制其热负荷,对各机型冷却系统进行改进:扩缸变型后的三种柴油机的燃烧室均采用吊钟式涡流室结构:采用改进活塞、活塞环来减少摩擦损失。扩缸变型一方面增大功率;另一方面产品的主要性能达到国内先进水平:与老产品的工艺继承性好、零部件通用化程度高。
Explain the 165F diesel engine cylinder expansion variant of the guiding ideology: the crankshaft, body, main bearing and other parts of the strength analysis: In order to effectively control the thermal load, the cooling system for each model to improve: After expansion cylinder variant of the three diesel engine The combustion chamber adopts the bell-type vortex chamber structure: the use of improved piston, piston ring to reduce friction loss. On the other hand, the main performance of the product has reached the advanced domestic level: the inheritance of the technology with the old product is good, and the degree of commonality of components and parts is high.
