东方红—75发动机(即4125A发动机)是我国科技人员在原AE54发动机基础上改进的发动机。核机在既不增加发动机尺寸、重量,又不增加其他设施的情况下,提高了动力性能和经济性能,获得了较高的比功率、升功率、比重量,是我国在拖拉机设计和生产上的新尝试。但该机在修理过程中在在出现功率不能恢复95％,机车排烟的现象,其原因是什么?如何去解决呢?经过几年生产实践中的探索和研究,谈谈自己的粗浅认识。
Dongfanghong -75 engine (that is, 4125A engine) is our science and technology personnel based on the original AE54 engine to improve the engine. The nuclear power plant not only increases the engine size and weight but also does not increase other facilities, improves the dynamic performance and economic performance, and obtains the higher specific power, the higher power and the higher specific weight, which is the first time that China’s tractor design and production New attempt. But the aircraft in the repair process in the presence of power can not be restored 95%, locomotive smoke phenomenon, what is the reason? How to solve it? After several years of production practice exploration and research, to talk about their superficial understanding.
