Precautions for Using Vehicle Fire Extinguishers

Vehicle fire extinguishers are generally portable dry powder extinguishers. The usage method is as follows: Open it about 5 meters away from the burning object and tear off the small lead block. Pull out the safety pin. Press down the handle with your right hand and lift the extinguisher, then hold the nozzle with your left hand and spray the dry powder towards the burning area. Keep the fire extinguisher upright and direct the dry powder jet towards the base of the burning flame. When using it outdoors, pay attention to standing upwind and spraying. As the range shortens, gradually approach the burning area to improve fire extinguishing efficiency. Fire professionals remind car owners that vehicle fire extinguishers are essential firefighting equipment in the car and have an expiration date. They must be configured and replaced as required. When using a vehicle fire extinguisher, pay attention to the following three points: The fire extinguisher can only be used to put out initial fires. When you notice smoke or unusual odors from the car, you should use the fire extinguisher promptly. When using the fire extinguisher, do not spray it at the surface of the flame but aim at the base of the flame. Only move the extinguisher away after confirming that the flame is completely extinguished. Open the engine hood in time to locate the fire source as soon as possible.

Is 16GB sufficient for a dash cam?

A 16GB memory card is generally sufficient for a dash cam. Most dash cams on the market support MicroSD cards with a maximum capacity of 32GB, with the mainstream options being 8GB, 16GB, and 32GB. 1080P resolution is essentially the standard for dash cams. Taking an 8GB memory card as an example, it can store up to 180 minutes of 1080P video, which is barely adequate. Therefore, memory cards below 8GB have largely become obsolete. Dash cams typically record in a loop, automatically overwriting the oldest footage when the TF card is full. This feature usually requires no manual configuration. In other words, when the dash cam's memory storage is full, it will automatically overwrite the oldest recordings. Dash cams allow users to set the duration of video clips, with common options being 1, 3, 5, 10, or 15 minutes. Most users opt for 3 or 5-minute clips, as this results in moderately sized files.

What is the difference between 16-inch and 17-inch wheels?

16-inch and 17-inch wheels differ in the following aspects: Size difference: 17-inch wheels are larger than 16-inch wheels. Aspect ratio difference: Generally, larger car tires have a lower aspect ratio, so 17-inch wheels have a smaller aspect ratio compared to 16-inch wheels. Shock absorption capability difference: 16-inch wheels have thicker sidewalls, providing better shock absorption on bumpy roads than 17-inch wheels. However, 17-inch wheels offer more responsive handling at high speeds but transmit stronger road feedback on uneven surfaces with weaker shock absorption. Tire blowout probability difference: In case of a tire blowout, 17-inch wheels' larger diameter results in less body tilt, reducing the likelihood of sudden directional changes, thus making them less prone to blowouts.

How to Solve Only NO Exceeding the Standard?

If the NO level in the exhaust gas is significantly exceeded, the first step is to clean the cooling system and the heat dissipation system, and even flush the lubrication system. Here are some related introductions about exhaust gas: Control the flow rate of the cleaning agent: The flow rate of the cleaning agent should be controlled to the point where the engine idles with slight vibration as the optimal condition. If the engine vibrates severely during the cleaning process, immediately reduce the flow rate of the cleaning agent. Some 4S shop technicians, aiming for speed, inject the cleaning agent into the engine at a high flow rate, which not only damages the engine but also reduces the cleaning effect. Cleaning of the three-way catalytic converter: The three-way catalytic converter should be cleaned and maintained every 30,000 kilometers, and those with the means can clean it every 10,000 kilometers. Under normal maintenance conditions, the service life of the three-way catalytic converter is between 150,000 kilometers and 200,000 kilometers before replacement is needed.

Why Won't a Motorcycle Engine Start When Cold?

Typically, this is caused by insufficient cylinder pressure due to cold weather reducing the performance of the engine oil. Other reasons why a motorcycle won't start include: Fuel system faults: Mainly caused by issues with the fuel switch (not delivering fuel), fuel filter (blockage), carburetor (not delivering fuel or overly rich mixture), or bent fuel lines. Electrical faults: Short circuits in electrical components (e.g., ignition switch, ignition coil, ignition module, or magneto failure) or open circuits caused by loose wiring harness connectors. Air pressure faults: Insufficient cylinder compression, improper air filter element resistance, or engine intake/exhaust faults, among others.

Why is the car cigarette lighter not working?

The reason the cigarette lighter is not working could be due to contact issues or damage to the cigarette lighter socket. Here are the relevant details: Contact Issues: Due to prolonged use and repeated insertion and removal, the spring clip may become loose, preventing the cigarette lighter from receiving power. You can first test it with a household appliance to check if it's functional. Use a multimeter to test the contact surface by setting it to the continuity test mode. Damaged Power Plug: Repeated plugging and unplugging or improper use may cause a short circuit, blowing the fuse. Check if there is a 12V voltage output. If 12V is present, it indicates the circuit is functioning properly.
