The explosive mixture of the petrol engine is provided by a carburettor , but in the case of the diesel engine the supply is effected by an injection or jerk pump which forces a shot of fuel into each cylinder in turn according to the correct firing sequence 翻译：汽油发动机由一个化油器输送可燃混合气体，而柴油发动机，由一个喷射泵或柱塞式燃油泵实现燃油供应，此泵根据正确的点火顺序把少量燃油依次压入每个汽缸。
The new unit has following technical features : ( 1 ) the unit ' s load is balanced by means of the accumulator and hydraulic cylinder with special structure ; ( 2 ) the installed power of the unit can be reduced greatly by adopting the accumulator ; ( 3 ) variable frequency speed regulation ensures good energy saving effect , and the closed oil circuit requires less hydraulic oil ; ( 4 ) a bi - directional hydraulic lock in the oil circuit ensures the stability and safety of the operation of the pumping unit 新型机具有4个技术特点： ( 1 )由于活塞柱塞式液压缸的特殊结构和液压蓄能器的配合使用，在平衡抽油机大部分载荷时，不需另外增加配重，可减小抽油机体积、质量和占地面积； ( 2 )抽油机下冲程时，与活塞柱塞式液压缸相连接的蓄能器吸收能量，上冲程时储存在蓄能器中的能量补充载荷上行所需的能量，大幅度降低抽油机装机功率； ( 3 )利用变频容积调速节能效率高，闭式油路节省液压油，同时大大减小液压泵站的体积； ( 4 )在闭式油路中采用双向液压锁可使抽油机的启停更加平稳、迅速，其工作的稳定性和安全性更好。
Jingde cmpany has an annual production capacity of 1 , 500 , 000 carburetors for motorcycles and general - purpose gasoline engine . presently , the company produces plunger - type and vacuum - type carburetors and other kinds in 60 varieties of 15 series . and more environment - foiendly and energy - saving series of products will come to the markdt . all these products can equip all kinds of motorcycle end products , power gasoline engine and general - purpose gasoline engine series . “ jingke ” carburetors have succeeded in equipping many famous and high - quality brands of motorcycles such as jialing , jianshe , longxin , zongshen , lifan of chongqing and tianma , wuyang of guangzhou . the company offers guarantees of repair , replace of refund of its products . on the other hand , through the raise of its reputation in the southeast asia markdt and through market re - radiation , the company has begun expoducts to lndia , north america and middle east in batches 京科公司年生产摩托车及通用汽油机化油器能力150万台，目前生产的柱塞式和等真空式化油器已达15个系列60个品种（并将有更多的环保节能型系列新品面世） ，可与各式摩托车成车、动力和通用汽油机系列配套， “京科牌”化油器已和包括重庆的嘉陵、建设、隆鑫、宗申、力帆，广州的天马、五羊等诸多名优车成功配套，并对产品实行三包承诺，同时，经过东南亚市场信誉度的提高和再辐射，已开始大批量出口印度、北美及中东地区。
To directly estimate the life of this kind of motor , and to design a orbit curve with the longest life at same condition , this paper gives theoretic research of the equal contact stress inner curve of radial piston motor . the research is divided into four parts : 1 ) taken all forces the piston endured into consideration when radial piston motor working , the force between roller ( or ball ) and orbit is deduced . the simple style of the press expression can be confirmed by ignoring minor influence factors after analysis all factors that will influence this press 静压传动技术在各类工程机械中得到广泛的应用，对作为其核心部件的径向柱塞式低速大扭矩液压马达的研究显得十分重要，为了能直接对这种马达进行寿命估计，并能在相同工况下求得寿命最长的轨道曲线，本文从设计等接触应力内曲线的角度对这类马达作探讨性的研究，主要从以下四个方面进行： ( 1 )综合考虑径向柱塞式液压马达工作时的各种主要受力状况，对柱塞组件进行受力分析，并通过仿真分析影响轨道和滚动体间正压力的各个因素，得到正压力的简化表达式。
