Where to Place a Fire Extinguisher in the Car?

For personal safety, the fire extinguisher in a car is generally placed inside the cabin, commonly under the driver's seat or the front passenger's seat. Types of fire extinguishers: Dry powder fire extinguishers, ultra-fine dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers, but dry powder fire extinguishers are the most commonly used. Avoid direct sunlight: Car fire extinguishers produced by reputable manufacturers are safe to keep in the car and are not prone to explosion. However, they should be kept away from high temperatures or direct sunlight to prevent hazards. Car owners should also pay attention to the expiration date of the fire extinguisher and stop using it once it expires.

Can You Still Drive When the Car Shakes Violently?

Normally, the car should remain relatively stable without significant shaking during idling or driving. There are two scenarios: 1. If you can clearly feel strong vibrations but the warning light is not on, you can continue driving at a lower speed and head to a repair shop as soon as possible to diagnose the cause of the shaking. 2. If the car shakes extremely violently with abnormal noises and the warning light is on, you should stop immediately and call for assistance. Additional Information: Car shaking mainly occurs in the following situations: 1. Engine Shaking. The engine may shake due to issues like carbon buildup, cylinder misfire, or detonation, which can also cause the car body to vibrate. When checking for engine-related shaking, also inspect the condition of the engine mounts, as one of their functions is to reduce the transmission of engine vibrations to the car body. 2. Brake Shaking. Brake shaking is often caused by grooved brake discs. You can feel noticeable unevenness when touching the surface of the brake disc, and in severe cases, the edges of the brake disc may protrude significantly. Depending on the thickness of the brake disc, you can choose to machine it or replace it with a new one. 3. Gear Shift Shaking. Gear shift shaking might be due to severely worn clutch plates or insufficient clamping force. This type of shaking caused by clutch issues is not noticeable during steady driving but becomes apparent during gear shifts or rapid acceleration. 4. High-Speed Shaking. High-speed shaking could be due to unbalanced wheels or abnormal tire wear. Wheel balancing refers to the even distribution of mass around the wheel's circumference; otherwise, the wheel will shake violently at high speeds. If the tire surface shows wave-like abnormal wear, it will not only cause shaking but also produce loud tire noise while driving.

What Causes a Motorcycle to Suddenly Stall While Riding?

Motorcycle suddenly stalling while riding can be caused by the following reasons: Electrical Circuit and Component Failures: This possibility arises from low-voltage power failure during riding, leading to stalling. In such cases, you should primarily inspect the ignition and starter switches, as well as the fuse box. Additionally, failures in the ignition coil, capacitor, or electronic ignition module may also cause this issue. Fuel System and Sensor Failures: Damage to the fuel pump, fuel line rupture, blockage in the fuel inlet, or an empty fuel tank; faults in the throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, or camshaft position sensor can also lead to stalling. Other Failures: Severe issues such as engine timing system disorder, incorrect timing system calibration, or engine valve collision are more serious faults that prevent the motorcycle from starting, requiring rescue assistance.

How much can wearing a seatbelt reduce the risk of injury?

Wearing a seatbelt can reduce the risk of injury by 80%. Introduction to seatbelts: Car seatbelts are safety devices designed to restrain occupants during a collision, preventing secondary collisions with the steering wheel, dashboard, etc., or avoiding injuries and fatalities caused by being ejected from the vehicle during a crash. Working principle: The retractor contains a ratchet mechanism. Under normal circumstances, occupants can pull the webbing smoothly and freely while seated. However, when the continuous pulling of the webbing from the retractor stops abruptly or when the vehicle encounters an emergency situation, the ratchet mechanism engages and automatically locks the webbing, preventing it from being pulled out further.

What Causes Transmission Noise?

Transmission noise can be attributed to the following reasons: Presence of internal contaminants: In many cases, it's not due to damage to the internal valve body, but rather the accumulation of stubborn dirt and contaminants inside. Especially when these impurities gather in the valve body, they can form blockages that prevent effective regulation of oil pressure, leading to issues like jerking, impact, and slippage. Excessive transmission temperature: High temperatures can degrade the quality and frictional properties of automatic transmission fluid, increasing friction and wear, which results in transmission noise. Simultaneously, sludge forms inside the transmission, causing jerking and impact. If the temperature exceeds 120 degrees, rubber sealing materials begin to harden, eventually leading to leaks and reduced hydraulic pressure. At even higher temperatures, the transmission starts to slip, and this slippage further raises the temperature. If not addressed promptly, the transmission may become irreparably damaged.

Can ETC be installed at the black dot position on the car?

The ETC device can be installed at the black dot position on the windshield, as long as it does not obstruct the driver's view and can detect the toll station's equipment. However, installing it at the black dot position on the windshield has a drawback: the solar charging capability of the ETC device may weaken, and over time, it might run out of power. The general installation position for ETC in small cars is the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, the ETC should be installed in the microwave window area. Below are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a significant backward tilt, which reduces the driver's field of vision. If this is not considered during ETC installation, it can increase the driver's blind spots. Installing it on the right side behind the rearview mirror can help avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. Precautions for using ETC: The ETC transaction sensing range is 8 meters. To prevent issues caused by the ETC device of the vehicle in front, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic payment for the front vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information, leading to payment failure. When using a debit card linked to ETC, insufficient balance may also cause payment failure.
