电喷喷油器衔铁行程测量工具 第三套方案共轨喷油器检测仪表及工具 衔铁升程及调整垫片 BOSCH 电装 西门子 德尔福系列 共轨拆装工具及配件 方便操作 功能完善 易于操作 精度高 价位合理1、专用设备检测。就是把喷油器拆下，拿到喷油器试验台检测。若检测的喷射压力达不到相应的技术标准，喷油器的雾化程度不好，有滴油或泄漏现象，而且经过清洗和调整无法恢复的喷油器，都必须更换。</p><p>2、在发动机上检测。</p><p>（1）通过发动机冷机启动的难易程度和启动后的排气烟色可判断喷油器的好坏。发动机冷机启动的难，启动后的排气烟色有白烟或黑烟，若供油角度和气缸压力正常，喷油器和高压油泵故障的可能很大；</p><p>（2）想要具体判断是哪一缸的喷油器工作不好，可以采用断缸法。发动机启动后，保持一个稳定的转速，然后逐一松开高压油管，就是断开一个缸的供油，看看发动机的转速有否变化：如果断缸后发电机转速下降明显，说明这缸的燃烧对发动机有作用，这缸的喷油器是好的；如果断缸后发电机转速下降不明显，说明这缸的燃烧对发动机没有作用，而且发动机的白烟或黑烟少了，说明这缸的喷油器是坏的。</p><p>（3）可以把喷油器拆出来，喷油嘴积碳很多，很湿，则这个喷油器工作不好。</p><p>（4）若发现机油变稀，机油有柴油味，很多时候也和喷油器故障有关。138548【22395】邹经理</p><p>??</p><p>值得注意的：</p><p>1、喷油器寿命与燃油系统的保养好坏有很大的关系。</p><p>2、使用1500小时应把喷油器和高压油泵上实验台座调试。</p><p>3、正常使用的情况下，喷油嘴应该是整车付的更换。</p><p>4、检测喷油器的同时，不要忽略度高压油泵和输油泵的检测</p><p> Efi fuel injector armature stroke measuring tool The third set of common rail injector testing instrument and tool armature lift and adjusting shim BOSCH Siemens Delphi series denso common rail disassembling tools and accessories is convenient operation function is perfect Easy to operate with high precision 1 reasonable prices, dedicated equipment test. Is the fuel injector to be removed, to get the injector test bench test. If the injection pressure of test can not meet the corresponding technical standards, the degree of atomization injector is bad, have a drip or leak phenomenon, and won't recover after cleaning and adjustment of fuel injector, all must be replaced.</p><p>2, on the engine test.</p><p>(1) through the engine to the difficulty of the cold machine start and start after the exhaust smoke can judge of injectors.
