农业机械上采用的发动机大都是柴油发动机,如联合收获机、拖拉机等,也有采用汽油发动机的,如水泵机组、喷雾机、播种机等。农业机械气缸的密封性能的好坏直接影响气缸压缩终了的压力,也决定了农业机械的动力性能发挥和燃油经济性。农业机械气缸的密封性能是由气缸、
Most of the engines used in agricultural machinery are diesel engines, such as combine harvesters, tractors, etc., and gasoline engines, such as water pump units, sprayers, seeders and the like. The sealing performance of agricultural machinery cylinder directly affects the final compression of the cylinder, but also determines the dynamic performance of agricultural machinery to play and fuel economy. Agricultural machinery cylinder sealing performance by the cylinder,
