What is the awareness of 12mis in the automobile industry?

In the automobile industry, 12mis refers to the failure mode rate (12-month intermediate failure rate) which reflects the durability of parts.

Car maintenance items:

1, 10000 km minor maintenance is machine filter and three filters of engine oil: machine filter, air filter and steam filter. Tuyue Com's customized maintenance package is an adaptive maintenance project according to the different needs of each model, which is exclusive to cars.

20,000 km maintenance, replacement of engine oil, mechanical filter, air filter, air conditioning filter element, and some routine inspections. ① Air filter Proper installation of air filter can reduce the wear of cylinder, piston and piston ring. Generally, it should be cleaned every 5000 km, and the air filter must be replaced every 10000 km.

Maintenance project

What are the daily car maintenance items? Automobile is a very complicated big machine, and it is inevitable that various mechanical parts will be worn during operation, which is caused by external human factors, environment and other factors. According to the driving condition of the car, the manufacturer will formulate corresponding car maintenance projects. What are the common maintenance items?

Project 1, minor repairs

Contents of minor maintenance:

Minor maintenance generally refers to routine maintenance items to ensure the performance of the vehicle after driving a certain distance within the time or mileage specified by the manufacturer. It mainly includes replacing oil and oil filter.

Interval of minor maintenance:

The time for minor maintenance depends on the effective time or mileage of the oil and oil filter used. Different brands of mineral engine oil, semi-synthetic engine oil and whole synthetic engine oil have different validity periods, please refer to the manufacturer's recommendation. Oil filters are generally divided into conventional oil filters and long-acting oil filters. The conventional oil filter is replaced by oil, and the long-acting oil filter has a longer service life.

Supplies in minor maintenance:

1, engine oil is the lubricating oil for engine operation. It can play the role of lubrication, cleaning, cooling, sealing and reducing engine wear. It is of great significance to reduce the wear of engine parts and prolong the service life.

2. The oil filter is a component used to filter oil. Engine oil contains a certain amount of colloid, impurities, moisture and additives; In the process of engine operation, metal chips, impurities in the inhaled air, oil oxides, etc. generated by the friction of various components. Are the targets of oil filter. If the oil directly enters the oil circuit without filtering, it will have an adverse impact on the performance and life of the engine.
