在修理工作中,4125A型发动机普遍存在着修后马力不足和耗油率增加的问题。针对这个问题,我厂自1981年以来对50多台4125A型发动机进行了摸索和实验,经过两年多的实践,基本解决了4125A型发动机马力不足和耗油高的问题。在1981年前我厂修理出的4125A型发动机最高功率为73马力,最低功率仅为69马 In the repair work, 4125A-type engines generally lack of horsepower and fuel consumption increased the problem. In response to this problem, our plant has been exploring and experimenting with more than 50 4125A engines since 1981, and after more than two years of practice, basically solved the problem of insufficient horsepower and high fuel consumption of the 4125A engine. In 1981, our factory repaired the 4125A engine maximum power of 73 horsepower, the lowest power of only 69 horses
