| 摘 要： | 根据拖拉机和发动机的原理及其工作能力的定义,提出发动机功率和耗油率使用限值的定义,以及确定使用限值的依据,找到由于发动机技术状态恶化而引起的功率下降与耗油率上升的关系;通过计算与试验分析,确定了小型拖拉机发动机功率和燃油消耗率的使用限值分别为90％及115％的标定值,为制订小型农用拖拉机运行中功率和耗油率标准提供了依据。

| Abstract: | Based on the principles of tractors and engines and the definition of their work capability, the definition of limit value of power and oil consumption of engines in use is made, and the basis for their delimitation is given. The relationship between the decrease of power and increasec of oil consumption resulting from deterioration of the technical state of the engine has been found out. By means of calculation, test and analysis, limit value of power and oil consumption of small tractor engines in use delimited as 90%andll5% of the rated power and oil consumption, respectively, which may serve as the basis for delimiting power and oil consumption standard of small farm tractors in operation. |
