Maintenance Of Diesel Engine
- Jan 26, 2018 -

To extend the life of the diesel engine, in the use of the process, we should strengthen the air filter, oil filter and fuel filter three kinds of filters maintenance, fully play their role.

air filter in the installation can not be installed, reverse or wrong to install the sealing washers and rubber joints, and to ensure that the tightness of the embedded place. The use of paper dust cup air filter, each work 50-100 hours, to remove dust 1 times, can be used to brush the surface of the dust off, if the working time more than 500 hours or damaged, should be replaced in a timely manner. Use oil bath air filter, each work 100-200 hours, the application of clean diesel oil cleaning cartridge, and replace the lubricating oil, if the filter has been broken, it needs to be replaced immediately, and attention in use, according to the provisions of the added lubricant.

Lubricating oil filter in the use of diesel engine if not timely maintenance, filter plug, lubricating oil pressure increase, safety valve open, the direct flow of lubricants to the main oil, will aggravate the wear of lubrication surface, affecting the life of the diesel engine. Therefore, the lubricating oil filter each work 180-200 hours, must clean 1 times, discovers the breakage, should replace immediately, prevents the impurity to enter the lubrication surface. Diesel engine seasonal use, but also should be cleaned crankcase and lubrication surface, the method is to use lubricating oil, kerosene and diesel mixture for washing oils, can be released after the lubricating oil to wash, and then, the diesel engine running at low speed for 3-5 minutes, then put the washing oil, add new lubricants.

Fuel oil supply system in a variety of fuel filters, each work 100-200 hours, should be cleared of debris 1 times or replacement, and the fuel tank and the oil pipelines for a comprehensive cleaning. Especially for the electronically controlled common rail system, because of the high pressure precision injection, the precision of the coupling parts of fuel system, the small gap between the oil filter, the filtration efficiency and water separation efficiency are put forward higher requirements. One-stage oil-water separator, one-stage diesel oil filter, the efficiency of the separation is greater than 95%, particle filtration efficiency of 3-5 micron filtration efficiency is greater than 98.6%. such as Bosch, Filter uncommon (Luber Finder), Fleetguard (Fleetguard), Manhu (Mann-hummel), Parker (Parker), etc., domestic Daffit (Difite) and so on. In the daily maintenance, should be particularly careful, found abnormal, or mileage and time to meet the engine requirements, to be replaced in a timely manner. In the seasonal transition oil change, the entire fuel supply system for all parts of the cleaning. The diesel oil used should be in accordance with the seasonal requirements and must be treated with 48 hours of precipitation purification.
