What model battery does the Baojun 730 use?

The Baojun 730 uses a Camel brand 86550T-12V-55Ah-550CCA battery. The car battery is installed in a suitable position with special safety considerations. If battery replacement is necessary, the electromagnetic compatibility, size, maintenance, output power, and safety requirements of the new battery should be considered before purchase. Methods to check the battery condition are as follows: 1. Routine inspection: Check whether the battery is firmly installed, whether the battery cables and terminal connections are secure, and whether the contact is good. Observe whether the battery casing is cracked. 2. Status check: Modern cars generally use maintenance-free batteries. Most of these maintenance-free batteries have a density indicator on the cover, commonly known as the "magic eye," which changes color according to the changes in the electrolyte density, displaying the battery status through different colors. Usually, when the magic eye is green, it indicates that the battery has sufficient power and is in normal condition; when the magic eye is black, it indicates that the battery is low on power and needs to be charged or replaced promptly; when the magic eye shows light yellow or no color, it indicates that the battery's acid level is too low or there is an internal fault, requiring repair or replacement. 3. Liquid level check: Check whether the electrolyte level is at the specified position. On the side of the plastic-cased battery, there are two liquid level lines marked: MAX and MIN. The battery status display indicates that the electrolyte level should be maintained between these two lines. Under no circumstances should the electrolyte level exceed the MAX mark or fall below the MIN mark.

What Causes Spark Plugs to Fail Frequently?

Common reasons for spark plug failure include the following: Improper spark plug gap adjustment. If the gap is too small, it not only limits the contact area between the spark and the air-fuel mixture but also suppresses flame kernel growth due to the quenching effect of the electrodes. Although a spark occurs, it is weak, making ignition of the mixture difficult. Conversely, if the gap is too large, the ignition voltage provided by the system may be insufficient to generate a spark between the electrodes. Cracked spark plug skirt. High-voltage current can arc through the crack, causing leakage and preventing a spark at the electrodes. Electrode carbon buildup. Excessive carbon deposits on the spark plug can cause the center electrode to leak current to the surroundings instead of jumping to the side electrode, resulting in a short circuit and no spark. This can further damage the insulator and render the spark plug unusable. Electrode damage. Prolonged electrical erosion from sparks or chemical corrosion from combustion gases can cause the electrodes to break or detach, preventing sparking. Low insulation resistance of the spark plug. This condition reduces the ignition voltage applied to the spark gap, weakening the spark or completely disabling ignition. Short circuit in high-voltage wiring. If the ignition coil-to-distributor high-voltage wire leaks, the entire engine may fail to start. If the distributor-to-spark plug wire leaks, one cylinder's spark plug may not fire. Eroded platinum contacts. This can prevent all spark plugs from firing, making the engine unable to start or run normally. Symptoms of spark plug failure include: Difficulty starting the car, whether cold or hot, often requiring multiple attempts. Engine shaking during operation. Reduced power output, noticeably weaker than usual. Increased fuel consumption. Engine stalling. Failed emissions tests. Faulty spark plugs should be replaced promptly. The replacement steps are as follows: Open the hood and remove the engine's plastic cover. Disconnect the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove each spark plug, ensuring the area is free of debris like leaves or dust. Insert the new spark plug into the hole, hand-tighten it a few turns, then use the socket to secure it. Reinstall the high-voltage wires in the correct firing order and reattach the cover. Replacement interval: Under normal maintenance, spark plugs should be replaced every 40,000–60,000 km. However, this may vary by brand and engine type, so consult the owner's manual for specifics.

Can I make a U-turn before entering the highway?

Before entering the highway, if there is a U-turn sign, you can make a U-turn directly; if there is no sign, you cannot make a U-turn. Below are the relevant details: 1. Before entering the highway entrance, if there is a U-turn sign, it is allowed to make a U-turn; if there is no sign, you cannot make a U-turn. Forcing a U-turn is considered driving against traffic and will result in a 3-point deduction and a fine of 200 yuan. 2. If you have entered the toll station, you cannot make a U-turn and must proceed to the next exit. Making a U-turn or reversing on the highway will result in an immediate 12-point deduction. 3. The highway entrance toll station is a common place for point deductions. When passing through an ETC lane, you must slow down; driving too fast may result in being caught on camera.

What are the reasons for the decrease in coolant?

Reasons for the decrease in coolant: 1. The engine operating temperature is too high, causing some of the coolant to evaporate. 2. There may be cracks in the cylinder head gasket or cylinder block, allowing coolant to enter the engine and be burned. 3. There may be a leak in the cooling system, causing continuous coolant leakage. Here is some related information about coolant: The main function of coolant is to cool the engine and provide anti-rust protection, among other benefits. It is primarily composed of a mixture of water, ethylene glycol, propylene glycol, and other compounds, with specific boiling and freezing points. Particularly important is the freezing point of the coolant, which is generally around minus forty degrees Celsius.

What is the principle of a 360-degree panoramic camera in a car?

The principle of a car's 360-degree panoramic camera is to synthesize the images provided by 180-degree wide-angle cameras installed at the front, rear, and sides of the vehicle into a bird's-eye view displayed on the in-car monitor. The components of a car's 360-degree panoramic camera include a hardware system and a software system. Its function is to visually monitor the surroundings of the vehicle, making it easier for the owner to drive and park while avoiding inconveniences caused by blind spots. The functions of a car's 360-degree panoramic camera are: 1. Dashcam; 2. Surround-view panoramic display with automatic image switching; 3. Vibration-activated recording when the engine is off.

What to Do When the Car Horn Gets Wet

Methods to handle a wet car horn are as follows: 1. First, disconnect the negative terminal of the battery to cut off power to the horn; 2. Remove the horn, shake off the water, then use a hair dryer to dry it, and let it ventilate for 24 hours before reinstalling; 3. If the horn is already damaged, it needs to be replaced with a new one. Methods to prevent the car horn from getting wet are as follows: 1. Try to install the horn in a higher position and at a 60-degree downward angle, which is widely recognized as the best position because it not only effectively prevents water from entering the horn but also allows any water that does enter to drain out without accumulating inside; 2. Find a board with good waterproof performance (a regular plastic board will suffice if unavailable) and fix it in the gap between the bumper below the horn and the space in front of the left front wheel to effectively block water splashed up by the wheels; 3. Use a pair of ordinary stockings to cover the upper and lower car horns, which can effectively prevent water from entering the horns.
