影响小型拖拉机功率·燃油消耗率因素

在小型拖拉机技术检测统计的基础上,对功率、燃油消耗率的影响因素进行了研究分析,表明:发动机转速、气缸压力、喷油压力、供油时间等不符合技术要求是造成功率、燃油消耗率不合格的主要因素.为小型拖拉机的合理使用与维修,确保其在最佳技术状态下工作提供了依据.

On the base of statistics of measurement and test results from small tractors, factors affecting power output and fuel consumption were analysed. The analysis shows that incorrect engine speed, pressure in cylinder liner, injection pressure and injection timing are the factors causing bad power output and fuel consumption. This will be helpful for reasonable operation and maintenance of small tractors so as to keep them under best conditions.
