What are the car maintenance items?

What are the daily car maintenance programs? Automobile is a very complex large machinery, in the operation of the mechanical parts will inevitably produce wear, coupled with external artificial, environmental and other factors, resulting in automobile wear and tear. According to the driving condition of the car, the manufacturer will formulate corresponding car maintenance items. What are the common maintenance items?

Item 1: Minor maintenance

Minor maintenance content:

Minor maintenance generally refers to routine maintenance items that are done at the time or mileage specified by the manufacturer to ensure vehicle performance after a certain distance of travel. It mainly includes changing oil and oil filter elements.

Minor maintenance intervals:

The duration of minor maintenance depends on the oil used and the age or mileage of the oil filter. Different brands of mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil have different validity periods. Please refer to the manufacturer's recommendation. The oil filter is generally divided into two types: conventional and long-term. The conventional oil filter is replaced with random oil. The long-term oil filter lasts longer.

Small maintenance items:

1, oil is the engine running oil. It can lubricate, clean, cool, seal and reduce wear of engine. It has important significance for reducing the wear of engine parts and prolonging the service life.

2, the oil filter machine is a component that filters oil. The engine oil contains a certain amount of colloid, impurities, moisture and additives; in the engine working process, the metal chips generated by friction of various parts, impurities in the intake air, oil oxides, etc. are all the objects filtered by the oil filter element. If the oil is not filtered and directly enters the oil circuit cycle, it will adversely affect the performance and life of the engine.

Item II: Major maintenance

Major maintenance content:

Major maintenance refers to the routine maintenance of replacing oil and oil filter, air filter and gasoline filter at the time or mileage specified by the manufacturer.

Major maintenance intervals:

Major maintenance is based on the existence of small maintenance, generally these two maintenance alternating. The spacing varies according to the brand difference of the car. Please refer to the manufacturer's recommendation for details.

Supplies in the maintenance:

In addition to changing the oil and oil filter, there are two items in the car maintenance:

1, air filter

The engine sucks in a lot of air during its operation. If the air is not filtered, the dust in it will accelerate the wear of piston sets and cylinders. Larger particles enter between the piston and the cylinder, causing serious "cylinder pulling" phenomenon. The role of the air filter is to filter out dust and particles in the air and ensure that sufficient and clean air enters the cylinder.

2. Gasoline filter

The role of the gasoline filter is to provide clean fuel for the engine and filter out moisture and impurities in gasoline. so as to optimize that performance of the engine and provide optimal protection for the engine at the same time.

Usually, when carrying out vehicle maintenance, the operator will do other inspections according to the specific conditions of the vehicle, and will also add other maintenance items, such as inspection and maintenance of engine-related systems, positioning inspection of tires, inspection of fastening components, etc.
