Divide the minute to see how Xichai can achieve a 40,000-kilometer oil change cycle
Xichai Changchang oil products So for the technology house, the problem has arisen. The maintenance mileage has been upgraded from 10,000 kilometers to 40,000 kilometers. What does Xichai do?
According to Xiaobian's multi-party inquiries, in order to realize long oil change technology, XiChai Kangwei products have undergone a series of upgrades.
The engine structure has changed. According to the person in charge of Xichai's technology, Kangwei's long oil change product has adopted a new body structure, and the new product has increased the length of the heat exchange water chamber of the oil cooler and optimized the water inlet circuit of the water cooler. At the same time, the number and size of the fins of the engine oil cooler have been optimized accordingly, greatly extending the service life of the oil.
Conway Engine
The biggest change is in the sump. Xiao Bian learned that the length of the oil pan of the Conway long oil change engine has been increased from the original 6.5L to 9L, increasing the amount of oil injected, and the filling amount has been increased from the original 6L to 8L (oil pan only, Does not include oil filter 0.5L), thus achieving a longer oil change intervals.
Oil is also the point of upgrading. Conway 4DW's five long oil change products use the XJC-designated CJ-4 grade and above oil. The engine is hot-tested and the original Xichai engine oil is added. It has the characteristics of low ash, low pour point and can take into account both Low temperature start can significantly improve the performance of diesel engines.
Do you think this is the end? Then you are wrong.
According to Xichai's “lean manufacturing†concept and requirements, Xichai has developed a set of perfect product cleanliness standards to provide protection for long oil change technology. According to the technicians, the current 4DW five-long oil change product adopts the cleanliness of the first stage, and a total of 33 parts increase the cleanliness requirements. Among them, 15 parts increased the standard for the weight method, 6 parts increased the standard for the largest particle method, and 18 kinds of parts proposed particle classification requirements. At the same time, Xichai will steadily increase its cleanliness standards.

In addition, Xichai also adopted a technology-leading high-pressure common rail + electronically controlled throttle + EGR + DOC + DPF technology program to ensure the long-term oil change while raising emission standards, and to avoid the SCR route brings The problem of refueling urea is more user-friendly.

After Xiaobian's introduction, have you already seen the "secret" of Xichai's long oil change technology? If you see through it, you must act quickly. Tell you secretly: This Conway engine is the only parent oil change product in domestic light vehicles.
