Battery failure or key malfunction, fuse blowout, solenoid valve not working. Here is the relevant content: 1. Car Door: The car door provides access for the driver and passengers to enter and exit the vehicle, while also isolating external interference. It helps reduce side impacts to some extent and protects the occupants. The aesthetics of the car are also related to the design of the door. The quality of a car door is mainly reflected in its anti-collision performance, sealing performance, ease of opening and closing, and other functional indicators. Anti-collision performance is particularly important because, during a side impact, the buffer distance is very short, making it easy to injure occupants inside the vehicle. 2. Central Door Lock System: To enhance convenience and safety in car usage, centralized control is implemented for the locking and unlocking of all four doors.

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

Baojun 730 spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to refer to the user manual for specific guidance. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark plug working principle: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.
