摘　　要：为研究喷油泵和喷油器调修对农业动力机械功率、油耗和排放的影响,在2台拖拉机样机上分别进行喷油泵和喷油器调修前后的动力输出轴对比试验。结果表明,调修后样机的标定工况点动力输出轴功率、变负荷和75%负荷以上燃油消耗率、最大烟度值都有明显改善。The PTO contrast tests were conducted on two tractor prototypes.One was done before the repairing of injection pump and injector and the other was after the repairing.Many indexes of PTO（such as PTO power at rated speed,specific fuel consumption at variable load and above 75%load,and the maximum exhaust smoke）were improved after the repairing of injection pump and injector.
