喷油嘴的工作原理：
在喷油泵开始供油前，喷油嘴针阀是关闭的，并由弹簧保持这种状态。喷油泵开始其泵油行程后，高压柴油通过进油管接头进入喷油嘴总成，经过喷油嘴体内的油道进入针阀承压锥面周围的油腔中，当柴油压力达到设定压力时，油压作用在针阀承压锥面上的向上推力将使针阀开启，柴油从针阀下被称为油囊的很小油腔到达喷孔，并从这些喷孔以细碎的油雾喷出。当泵油压力降低时，针阀弹簧使针阀落在阀座上，喷油过程随之结束。

喷油嘴早期损坏的原因及预防措施    
喷油嘴的作用是将燃油雾化成微粒，并将它们分布到燃烧室中和空气混合燃烧。因此，对喷油嘴要求有一定的喷射压力，一定的射程和一定的喷雾锥角，雾要良好，喷油结束时能迅速停油，没有滴油现象。喷油嘴的主要零件是针阀和针阀体，两者合称为喷油嘴偶件，它的正常使用寿命一般为2500h以上。但因使用不当，在实际中寿命超过1500h者廖廖无几。现就喷油嘴偶件早期损坏的原因及预防的方法作以下分析。  1 喷油嘴偶件早期损坏的原因        
（1）乱拆卸。大多数机手认为柴油机供油系统故障较为常见，所以柴油机一旦发生故障，往往不去认真查找引起故障的原因，而是对燃油供给系统逐一进行拆卸检查和更换。而喷油嘴偶件的加工、装配精度要求很严，拆卸安装一次，就可能缩短寿命几十甚至几百小时。此外，还可能因拆卸、安装不当造成 磕碰、脏污、划伤甚至变形，导致技术状态变差，使用寿命降低。        
（2）清洗不当。清洗喷油嘴偶件时与其他零件混在一起并使用不清洁的清洗液，甚至不清洗就组装使用。新偶件未彻底清洗防锈油，极易造成偶件工作表面磕碰划伤，沾染杂质磨料，在工作中磨损加剧。
（3）喷油压力调整不当。更换喷油嘴或高速喷油压力时，喷油压力调得过低或过高，均会使喷油嘴偶件的使用寿命缩短，尤其是喷油压力过高时，会造成喷油嘴偶件磨损加剧。        
（4）装配不当。少数机手为了防止漏油，将喷油嘴锁紧螺帽拧得过紧，使喷油嘴承受的压力过大， 产生变形，装配精度遭到破坏，造成偶件运动受阻而损坏。        
（5）燃油质量低劣。使用劣质燃油，由于其润滑性能，密封性能及粘度等指标不能满足使用要求，容易引起喷油嘴积炭等故障。此外，燃油未经净化处理、燃油滤清装置损坏或用拆除滤芯的办法来使油路 “畅通”等错误做法都会造成偶件使用寿命缩短。


喷油嘴早期损坏的预防措施          
（1）选用符合要求的燃油，严格执行燃油沉淀、过滤制度。燃油加注前至少要沉淀48h；根据季节、气温的变化使用规定标准牌号的燃油；不使用混合油；加油工具要保持清洁；燃油存放要进行密封。       
（2）燃油滤清器、燃油箱要按时清洗（滤清器每工作100h，油箱500h时要清洗一次），发现滤 芯和密封存圈破损应及时更换。        
（3）新喷油嘴偶件都涂有防锈油，在安装时，一定要用干净的柴油清洗，以清除表面的灰尘和防 锈油。        
（4）安装喷油嘴偶件时，应注意清洗针阀体台肩下端面与紧帽支撑台阶面。拧紧喷油嘴偶件锁紧帽时，应反复拧紧几次，不要一次拧紧；另要将调压螺钉放松，防止喷油器顶杆被顶弯，导致顶杆凹坑不 能很好地与针阀对中，发生偏磨。        
（5）调整喷油压力时，必须先进行喷油嘴密封性检查，高速时应调到规定压力，特别要注意，喷 油开始时的起喷和喷油终了时的断油要干脆。        
（6）喷油器总成往气缸盖上安装时，要清除安装孔内的积炭等杂物，并注意铜垫的技术状态。喷油器的拧紧力矩和压板螺松的紧固力矩大小应适当，用力过大易引起喷油嘴针阀体变形，导致针阀卡死。       
（7）保持喷油嘴散热良好，喷油嘴垫圈必须是铜垫，喷油嘴与安装孔之间应留有2~3mm的间隙，以保持良好的散热环境。        
（8）经常及时地校准供油时间和配气相位，做到柴油机不长期超负荷工作。还要保证发动机冷却 系统的技术状况良好。        
（9）检查柴油机时要仔细清除燃烧室进、排气门、活塞、缸套、排气管及喷油嘴周围的积炭，上 述部位积炭过多，都会引起发动机散热不良，排气不畅，局部高温，从而烧损喷油嘴偶件。        
（10）更换或拆装高压油管、柴油滤芯、柱塞副和出油阀副等部件时，应清洗后再安装。
