Beijing Hyundai brand-new Shengda 20 13 can accelerate from zero to 40. What is the problem of accelerating from 40 to 60?

The air contains a lot of dust, sediment and acidic substances, which are not only easy to be adhered by leaked fuel, but also easy to form a hard insulating layer under high temperature baking, which makes the heat dissipation performance of the parts worse, and is easy to be corroded by electrostatic adsorption of the car body and make it fade prematurely.

1, clean the air filter

Too dirty air filter will sharply prevent fresh air from entering the cylinder, resulting in excessive gas concentration, incomplete combustion, decreased power and excessive exhaust. Modern air filters generally use paper filter elements. Attention when cleaning: Do not use water or oil to clean, but use the method of beating and blowing. The beating method is to gently pat the end face of the filter element to make the dust fall off. Blow-clean method refers to blow-clean the inside of compressed air filter element, and the air pressure and force shall not exceed 0.3N/Pa.

2. Clean the oil filter

If the oil filter is blocked, it will hinder the flow of lubricating oil, resulting in poor engine lubrication, increased wear and even tile burning. Therefore, it should be cleaned or replaced regularly. If the climate is dry, it is usually replaced every 8000 kilometers. It should be shortened to 5 000km and replaced once.

Step 3 clean the battery

Modern cars generally use maintenance-free batteries. First, clean the top of the battery to avoid inter-electrode short circuit caused by electrolyte or other impurities. Secondly, clean the battery terminal to prevent the connector from generating oxide and causing poor contact. The vent hole should be clear to prevent the hand from bursting due to excessive pressure or high temperature in the battery.

Generally speaking, the oil change cycle is 5000 kilometers, and the specific change cycle and dosage should be judged according to the relevant information of the vehicle type.

Not all models are suitable for the owner to change the oil himself, but we can learn to check the oil meter to judge whether it is time to change the oil. In addition, when changing the oil, the oil filter must be replaced.
