If the road sweeper truck was parked for a long time, the performance of the vehicle will gradually deteriorate due to the long-term connection with the air. In order to alleviate this undesirable situation, car owners should often maintain the parked vehicles to keep good performance. Here Hongfeng can give you some useful advice.
1. Prevent aging and deterioration of rubber products.
Rubber products on automobiles, such as tires, transmission belts, and dust covers, often experience aging, expansion or deformation, resulting in poor performance and shortened service life. The aging of rubber products is mainly due to the fact that rubber is an unsaturated polymer hydrocarbon, which can easily absorb oxygen in the air and be oxidized. At the same time, vulcanized rubber has a certain degree of air permeability, and oxygen can easily enter the interior to cause oxidation. What's more, direct sunlight can promote the rapid aging of rubber. When rubber products are contaminated by gasoline or engine oil, the rubber will expand in volume, loosen its gum, and decrease elasticity. In order to prevent the aging of rubber products, you should avoid direct sunlight and contact mineral oil contact.
2. Rust and corrosion of metals are mainly caused by the combined action of moisture, oxygen and corrosive substances in the air. Therefore, for cars that have been parked for a long time, the metal surface should be kept clean. The garage where vehicles are parked should always be ventilated to keep the relative humidity of the air below 70%. The dust, dirt and moisture on the car must be removed in time. The rusty parts and the surface of the machine parts should be coated with oil, grease or wrapped up with oiled paper. The pores on each assembly mechanism should be sealed to prevent air, moisture and dust from entering the interior.
3. Prevent the mildew of cotton and linen products. Cotton and linen products can easily absorb water. Especially in humid areas and rainy seasons, it is more susceptible to damp and mildew. Therefore, the car owner should check the cotton and linen products on the car frequently, and hang it in time to keep dry.
4. Gasoline fuel tanks should be tightly sealed and avoid excessive temperatures. You'd better not to store gasoline too long.
5. Check the working condition of the engine frequently. Start the engine at least once a month and run it for 4-5 minutes to check the engine's operation. If there is any abnormality, it needs to be adjusted and repaired in time. What's more, always check the battery. The electrolyte level of the battery must be 10-15 mm higher than the electrode plate. If it is insufficient, add distilled water in time, keep sufficient power, and charge the battery if necessary.
