Which Parts of a Car's Exterior Are Made of Plastic?

Several parts of a car's exterior are made of plastic: 1. Bumper Cover: Also known as the "bumper," it is actually just the auxiliary shell of the bumper, not the main structure. The bumper cover serves to absorb impact and energy, operates in relatively complex environments, and is large in size. Therefore, it is typically made of polypropylene (PP) due to its lightweight and good corrosion resistance. 2. Grille: Nowadays, many car models feature chrome-plated grilles, giving them a strong metallic appearance, but in reality, they are also made of plastic. The main function of the grille is to cool the engine and manage airflow at the front of the car, requiring excellent material plasticity—making plastic the ideal choice. 3. Headlight Covers: Headlight covers must ensure long-term use without affecting brightness and protect the headlights, demanding good plasticity, high transparency, and sufficient hardness. Therefore, high-performance optical plastics like polycarbonate (PC) are the perfect choice for headlight covers, as they offer high strength, UV resistance, and excellent toughness and light transmission.

Where is the air filter of the Dasheng E20 located?

The air filter of the Dasheng E20 is located on the side of the engine. Here is some relevant information about the air filter: 1. When replacing the air filter, you need to open the car's front hood, locate the position of the air filter, and loosen the clips or screws that secure the air filter. Some models use clips, while others use screws. 2. Generally, the replacement cycle of the air filter depends on the specific usage conditions of the car. The replacement time should also be determined based on the environment where the car is used. If the car frequently operates in areas with poor environmental conditions, it is recommended to regularly check the air filter. 3. During operation, the engine inhales a large amount of air. If the air filter is too dirty, external air will directly enter the engine, causing serious impacts. The impurities in the air can lead to significant wear and tear on the engine's internal components, affecting its performance and shortening its lifespan. 4. There are two types of air filters used in cars: dry type and wet type. The dry type air filter is the more commonly used one in vehicles.

What are the symptoms of a spark plug being tightened too much?

The symptom of a spark plug being tightened too much is gas leakage, so we should not overtighten the spark plug when replacing it. Location of the spark plug: The spark plug is installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. Over the past decade, most car engines have been modified to have the ignition coil directly connected to the spark plug. Steps to replace a spark plug: Open the hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage ignition wires according to the firing order, and then secure the cover.
