Diesel engine oil class model description
Diesel engine manufacturers and loader manufacturers have launched their own brands of diesel engine oil, special for Weichai, Shangchai, Yuchai, Liugong, SDLG, Lonking, XCMG, etc. The grade of diesel engine oil can be roughly divided into CA, CB, CC, CD, CE, CF, CF-4, CG-4, CH-4, CI-4, CJ-4.
The quality grades of CF-4, CH-4 and CI-4 are from low to high. The quality of CI-4 mainly depends on the base oil and additives, so the oil change cycle of CI-4 is longer than that of other grades, and the wear resistance and corrosion resistance are also better. Introduced in 1990, the CF-4 is suitable for high-speed, four-stroke, natural intake or turbocharged diesel engines and can replace both CD and CE oil grades.
Introduced in 1998, the CH-4 is designed for high-speed four-stroke diesel engines that meet the 1998 US emission standards and use fuel with a sulfur content of less than 0.5%. It can replace CD grade, CF-4 grade, CG-4 grade. The CI-4 was introduced in 2002 and is available for high-speed four-stroke diesel that meets the 2004 US emission standards. For vehicles equipped with an exhaust gas recirculation system (EGR), the CI-4 oil is effective in maintaining engine stability and is suitable for fuels with sulfur content less than 0.5%. Can replace CD, CE, CF-4, CG-4, CH-4 oil grade.
Diesel oil is the lubricating oil used in diesel engines. Diesel engine is short for diesel engine. It is a high torque, high efficiency and good economy engine. It is powered by the combustion of diesel oil. The diesel engine application prospect is very broad, the global diesel engine application market is growing steadily. Many people use diesel engines every day, but they don't know how to maintain them. In fact, the maintenance of diesel engine is a very technical work, it is made of synthetic diesel oil. If the diesel engine is well maintained, the service life can even be extended.

Injured areas in Gansu, Zhouqu: Local people spontaneously searched for missing relatives' diesel generators | Diesel generators price / 2010-08-09
At about 4:40 am on the 9th, reporters rushed to the vicinity of Zhouqu county in Gansu. When the reporter was on the way to Zhouqu county, he saw rescue vehicles chase away from the county seat from time to time.
At about 7 o'clock in the morning, the reporter saw on the scene that because of the floodwaters from the dammed lake, the only road to the outside of Zhouqu County was submerged. Therefore, only one large forklift slowly transported pedestrians into the city. . Seven or eight large excavators are parked on the side of the road, waiting for the flood to recede into the city.
Today Zhouqu County is gloomy and there are faint hazes in the mountains nearby.
At the site of the mudslide disaster in Zhouqu county, about three to four hundred rescue workers from Sichuan Fire, Lanzhou Military Area Command, and Gansu Forest Armed Police have each started rescue operations.
In addition, many local people spontaneously search for missing relatives at the mudslide site. Some of them held gongs and shovels, and some simply used their hands to directly dig away the dirt and stones from the buildings. They expressed their dignified expression. Some women still cried because they couldn't hide their grief.
