10 . no assembly warranty will be delivered if such assembly as plunger , oil delivery valve assembly and nozzle assembly are worn out abnormally , because the customers use diesel oil which is not in conformity with quality demand or dirty diesel oil 因顾客使用不符合质量要求的柴油，或柴油太脏，导致柱塞偶件出油阀偶件喷油嘴偶件异常磨损的，偶件不给予保修。
The project is funded by the anhui oil pump and oil nozzle factory . the aim of this project is to develop the automatic separation system of injector valve and orifice , based on the pneumatic sensor and the mcu 本课题来源于安徽油泵油嘴厂，目的是研究一套价格为企业所接受的基于气动传感器并以单片机进行数据处理和控制的喷油嘴偶件针阀和针阀体自动测量分选系统。
The service condition of diesel injector nozzle is introduced , the failure reasons of diesel injector nozzle are mainly analyzed , the quality of diesel injector nozzle is improved and the useful life way of diesel injector nozzle is extended 摘要介绍了喷油嘴偶件的服役条件，分析了喷油嘴偶件失效的原因，对提高喷油嘴偶件质量和延长喷油嘴偶件使用寿命的途径进行了探讨。
1 . instead of old inner - mixed vortex nozzles , improved y - type nozzle is developed . the designing calculation of new nozzle and corresponding air distributed organ are made , and the atomization effect is verified and compared with old one 对原内混式旋流型喷油嘴进行改造，改用y型喷嘴，进行了喷嘴改造的设计计算和相应配风器的改造设计计算，比较和校核了其雾化效果。
The cavitation flow in a nozzle at steady spray of a diesel engine was simulated , and the formation mechanism and distribution of cavitation inside the nozzle were analyzed using mixed multiphase flow model coupled with cavitation model 摘要利用混合多相流体模型加空穴模型的方法，模拟了柴油机孔式喷油嘴稳定喷射时嘴内的空穴流动现象，分析了空穴在喷油嘴内形成机理及其分布情况。
The spray processes of throttling and normal pintle nozzles are investigated in this paper . the test results show that the better spray characteristics and spray quality can be achieved when the throttling pintle nozzle is used in small diesel engines 本文对节流轴针式和普通轴针式喷油嘴的喷油过程进行实验研究，试验结果表明，节流轴针式喷油嘴应用在小缸径柴油机上能取得良好的喷油特性和喷雾质量。
The important is that the expenses used on technical reconstruction only is 1 / 5 of an new importing equipments , but its processing quantity is almost equal to the importing equipments , completely can satisfy with the rigor craft request of the ejection nozzle ' s precision 更为重要的是用在其改造上费用只有进口设备的1 5 ，而加工质量与进口设备相当，完全满足了高精度小孔径喷油嘴的加工工艺要求。
Based on the analysis of the combustion in cylinder , the thorough research of multiparameters ( engine speed , load , ignition timing , injection timing , injection nozzle type , compression , ignition pattern etc . ) on methanol engine combustion cyclic variations is made on a 1130 single - cylinder diesel engine fueled with methanol 在燃用甲醇燃料的1130单缸柴油机上，通过缸内燃烧分析，对影响甲醇发动机循环变动的各种因素(转速、负荷、点火提前角、喷油提前角、喷油嘴类型、压缩比、点火方式等)进行了详细的研究。
