摘　　要：随着柴油机电喷技术的高速发展，越来越多的工程机械采用电喷柴油机作为动力源，电喷柴油机的喷射系统压力较高，当柴油的清洁度不高时，其中的杂质会在高压下高速冲击喷油嘴，造成喷油嘴的磨损，引起柴油机燃油消耗量增加、柴油机功率下降、噪声更大、怠速不稳定、排放增加等一系列问题。高效柴油加注预滤器采用多级过滤形式，能够过滤柴油中的90％以上的机械杂质、胶质和沥青质，有效提高柴油的洁净度。经试验证实，通过使用该预滤器，可以将柴油机燃油系统滤清器的更换周期延长3-4倍，减少燃油消耗5％以上，介绍了高效柴油加注预滤器的结构组成及工作原理。Following the rapid development of electronic injection technique on diesel engines, more and more construction machines adopt electronic injection diesel engines as power source. Pressure of injection system in electronic diesel engines is relatively high. When cleanness of diesel fuel is inadequate, impurities inside will pound the injection nozzle, which causes a series of problems, such as wear and increase fuel consumption of the engine, resulting in power decrease, noise increase, unsteady idle speed and increased emission. The high efficiency diesel filling strainer adopts multiple stages filtering. It can filter out more than 90% foreign matters, colloidal matter and asphaltine in diesel fuel and improve diesel cleanness effectively. It is demonstrated by tests that through adopting such filters, replacement interval of fuel filter can be increased 3 to 4 times and fuel consumption can be decreased by 5% odd. The structural composition and work principle of the high efficiency diesel filling strainer is described.
