As the saying goes, “three points depend on quality and seven points depend on maintenance.†As the heart of the vehicle, the engine also requires our maintenance and maintenance, but many users often overlook this point, and even regular service station maintenance is only Cope with it. Nowadays, the maintenance of the National IV engine is different from that of the National 2 and the 3 major pump engines. Some truck drivers still have the idea of ​​rejection of the Guosi engine. The big reason is that they are overwhelmed by maintenance and maintenance. Xiao Bian took everyone to learn about the maintenance and maintenance of the Weichai National IV engine.
The Weichai Guotai Engine's Precautions
When the National IV engine is in use, it is necessary to conduct a comprehensive inspection of the engine. Generally, before the delivery of a new car, the after-sales service personnel of the service station will help the user to carry out inspections, and fill in a form to confirm the various items of the inspection, and the user confirms. In this case, the customer tries to accompany the inspection as much as possible while learning. The methods and items inspected by the service personnel facilitate the inspection of the engine and the vehicle themselves.

The inspection items for the engine are generally whether the oil level and the coolant level meet the requirements, and whether the fuel quantity is sufficient; and check whether the oil pipeline, the fuel pipeline, the intake pipe and the cooling system are leaky, and start the engine. Keep the engine at idle speed and observe the condition of the engine, such as abnormal vibration and abnormal noise
The most important thing is that after the user purchases, he must read the instructions carefully. Do not feel that he is an old driver who has been driving for several years, and ignore it. The instructions will show some details that we need to pay attention to during use. Just like reading, every time you finish reading, you will have new gains. You often read Chang Xin.
The new engine of State IV is also required to run-in. Generally, the running mileage is 3000-5000Km. During the running-in period, the load should be reduced, and the diesel fuel in the national four or more countries must be used.
After the normal running-in period, the first protection of the vehicle will be carried out, and the engine will be fully checked, tightened, adjusted and lubricated in the first insurance. Mainly oil replacement, as well as oil filters and filter elements. And check, adjust the valve clearance; check the cooling fluid capacity and add enough; solid cooling pipe clamps, solid intake hose and flange connection; check the tightening belt, adjust the idle speed, and need to add grease Add grease to the area.
Daily maintenance of Weichai National IV engine
In the use of the National IV engine, it is necessary to take preventive measures and strengthen the daily maintenance during use, which plays an important role in extending the service life of engine components. Practice has shown that air, fuel, and oil are always kept clean, and that all components are adjusted in time, which can effectively extend the service life of the engine.
Daily inspection items should pay attention to the following aspects. After starting the engine, it is first necessary to check the operation of each instrument. Including: The oil gauge has no pressure display, if not immediately turn off the overhaul; fuel gauge pointer should be between "E" (empty) and "F" (full); coolant temperature indicator pointer should be after the engine is running for a while Within the scope of the dial; the pointer of the voltmeter must be above 24V; the pointer of the barometer should eventually be stabilized at 700kPa.
Most of the Weichai four engines use SCR after-treatment technology. Only a few light engines use EGR, and SCR requires the use of vehicle urea. However, many users do not pay attention to this, and it is not clear how to maintain and maintain them. .

The daily inspection and maintenance of the SCR after-treatment system of the National IV engine can help the engine's power and fuel consumption. The daily inspection and maintenance of the SCR aftertreatment system is mainly related to urea. The poor quality of the urea solution, low fluid level, damage to the filter screen, and blockage may cause damage to the urea pump and generate an OBD alarm, resulting in a decrease in engine power. The maintenance of the engine SCR aftertreatment system should first select qualified vehicle urea, and often check the urea level, urea tank filter, urea pump filter, pipeline is intact and blocked, the engine's SCR aftertreatment system also need to go regularly Service station maintenance, general maintenance mileage between 100000-120000 km.
Weichai's internal professionals introduced that users who pay attention to daily maintenance and maintenance, the failure rate will be reduced by more than 35%, fuel consumption decreased by more than 7%, visible, the importance of maintaining and maintaining the in-use vehicle process.
At present, the market is flooded with a large number of counterfeit parts, lubricants and urea. The use of counterfeit products will cause great damage to the engine. Therefore, users are reminded to purchase through the formal channels when purchasing parts and other products. The service station for repair and maintenance, increase the service life, is to reduce the cost of use.
