In view of the common rail system, due to high pressure precision injection, the fuel system of high precision, with small clearance, the fuel filter and water separation efficiency of the filter is put forward higher requirements. One stage oil water separator, one stage diesel fine filter, the water separation efficiency is more than 95%, the filtration efficiency of particulate filtration efficiency is greater than 98.6% 3-5. Such as Bosch (Bosch), filter out of the ordinary (Luber finder), fleetguard fleetguard, Mann Hu mann-hummel, Parker (Parker) and domestic have Duffett (difite). In the daily maintenance, should be particularly careful, abnormal, or travel mileage and time to achieve the engine, the need for timely replacement. In the transition season replacement, the parts to deal with the whole fuel supply system for cleaning. The use of diesel, should be in accordance with the requirements of the season, and the need to 48 hours of precipitation purification treatment.
Oil filter 180-200 hours per work, it should be cleaned 1 times, found damaged, should be replaced immediately, in order to prevent impurities from entering the lubrication surface. Diesel engine change garments according to the season of use, but also cleaning the crankcase and the lubrication of the surface, the method is used lubricating oil, kerosene and diesel hybrid subsequent washing oil, cleaning oil washing is added after the release of the lubricating oil in, then diesel engine running at low speed for 3-5 minutes, put as much as washing oil, add new lubricating oil.
The use of air filter paper set dust cup air filter, every 50-100 hours of work, to remove dust, use a soft brush will brush off the dust on the surface, if the working time more than 500 hours or damaged, it should be replaced in a timely manner. Using oil bath type air filter, every 100-200 hours of work, application of clean diesel cleaning filter, and replace the lubricating oil, if the filter has been broken, replaced immediately, and pay attention to in use, in accordance with the provisions of the add lubricating oil.
