How often should the spark plugs of the Baojun 730 be replaced?

The spark plugs of the Baojun 730 should be replaced every 40,000 kilometers. Spark plugs are devices used in gasoline engines to ignite the air-fuel mixture. They consist of a ceramic insulator on the outside, a metal conductor in the middle, and electrodes inside. Types of spark plugs include: 1. Standard spark plugs; 2. Projected insulator spark plugs; 3. Electrode spark plugs; 4. Seat-type spark plugs; 5. Pole-type spark plugs; 6. Surface-gap spark plugs. The working principle of a spark plug is: under the control of the engine, it introduces the high-voltage electricity generated by the ignition coil into the engine cylinder, creating a spark between the spark plug electrodes to ignite the air-fuel mixture, enabling the engine to operate normally.

How to Reissue a Road Transport Permit?

The reissuance procedure for a road transport permit is briefly outlined as follows: 1. Application Submission: In case of loss or damage to the road transport permit, the holder must verbally apply for reissuance to the road transport administration authority, obtain and fill out the "Road Transport Industry Permit Reissuance Application Form," detailing the time, location, circumstances of the loss or damage, and witnesses. 2. Reissuance Registration: The road transport administration authority will process the reissuance registration for the lost permit based on the submitted application form. The reissuance details should be recorded in the permit issuance ledger under "Reissuance or Modification Records." 3. Interim Permit Issuance: During the period of reporting the permit as lost, to avoid disrupting transport operations and ensure lawful business activities, the road transport administration authority will issue an interim permit (a supplementary page), retaining the main permit while allowing continued operation. The supplementary page must specify the reason for the interim permit and its validity period, which should not exceed one month. 4. Public Declaration of Invalidity: The road transport administration authority will provide the operator with a letter of introduction to publish a declaration of invalidity in a newspaper at the prefecture level or above. 5. Main Permit Collection: The permit officer at the road transport administration authority will issue the main permit upon presentation of the newspaper containing the published declaration.

How Often Should the Three Filters Be Replaced?

The three filters refer to the air filter, oil filter, and fuel filter, each with different replacement intervals. First, the air filter should be replaced every 10,000 kilometers. Second, the oil filter needs to be replaced every 5,000 kilometers. Third, the fuel filter should be replaced every 20,000 kilometers. Air Filter: It ensures clean air enters the engine. The air contains suspended dust, primarily composed of silica, which is harder than metal. Installing an air filter reduces wear on components such as cylinders, pistons, and piston rings. Fuel Filter: It ensures clean fuel and prevents vapor lock. During storage, transportation, and refueling, impurities and moisture may mix into the gasoline. These impurities can enter the fuel supply system and engine cylinders, accelerating wear. The fuel must be filtered before entering the fuel pump to ensure the proper functioning of the fuel supply system. Oil Filter: It filters engine oil to ensure smooth engine operation and is the most critical among the three filters. During internal combustion engine use, mechanical impurities such as dust, metal shavings, and carbon deposits continuously mix into the oil. Additionally, oxidation from air and combustion byproducts causes the oil to gradually form sludge. The combination of mechanical impurities and sludge can clog oil passages, accelerating wear on moving parts.

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

Over-tightening a spark plug can make it difficult to remove, and the base of the spark plug may break off. The force used when replacing a spark plug should match the required torque for the specific spark plug being used, as spark plugs of different sizes require different amounts of force. Steps for replacing a spark plug: Open the hood, lift the plastic engine cover, remove the high-voltage ignition wires, and mark each cylinder's position 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 everything is 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 high-voltage ignition wires in the correct firing order and secure the cover. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. The following standards can be used as a reference for maintenance: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs between 60,000 to 80,000 kilometers.

How to Remove Scratches from a Car's Front Windshield?

Clean the glass with a clean cloth to ensure there are no debris or impurities on the glass, and let it dry in a clean environment. Take a clean, lint-free cloth that is as smooth and non-shedding as possible, wring it tightly until no excess water drips out. Squeeze an appropriate amount of toothpaste onto the cloth according to the size of the scratch, adding more if necessary. It's best to use white, non-gel toothpaste, which is most suitable for removing scratches. Move the cloth in small circular motions over the scratched area for about 30 seconds, then rinse with clean water.
