1、柴油须沉淀。据有关部门测定,每吨柴油中含有50克左右的石英、矾土等杂质。如果柴油中的这些杂质不经过沉淀、过滤等净化处理,而直接进入燃油系统中使用,即使是很小的杂质进入柱塞、油阀、喷油器后,也会在高压和高速下,像磨料一样磨削精密偶件的表面,破坏其光洁度和配合间隙。长此以往,将使发动机燃烧过程恶化,排气冒烟、产生积碳,影响发动机各部件。因此柴油加入油箱前,至少沉淀48小时以上,这样柴油中各种微粒绝大部分沉淀到底层。取中上层
1, diesel must be precipitation. According to the determination of relevant departments, each ton of diesel contains about 50 grams of quartz, alumina and other impurities. If these impurities in diesel oil without precipitation, filtration and other purification, and direct access to the fuel system, even small impurities into the plunger, valve, injector, but also under high pressure and high speed, like Abrasive like grinding the surface of the precision parts, destroy their finish and with the gap. Over time, will make the engine combustion process deteriorates, exhaust smoke, carbon deposition, affecting the engine components. Therefore, before adding diesel tank, at least precipitation more than 48 hours, so most of the diesel particles precipitate to the bottom. Take the upper level
