The Principle of ETC Recognition

The principle of ETC recognition involves microwave-based dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station. This utilizes computer networking technology to perform backend settlement processing with banks, enabling vehicles to pass through toll stations without stopping to pay bridge or road fees. Below are specific details about ETC: 1. Name Meaning: ETC (Electronic Toll Collection), translated in Chinese as electronic non-stop toll collection, is an automatic tolling system for highways or bridges. 2. Function Introduction: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, it uses computer networking technology to perform backend settlement processing with banks, allowing vehicles to pass through highway or bridge toll stations without stopping to pay fees. 3. System Composition: It mainly consists of an automatic vehicle identification system, a central management system, and other auxiliary facilities.

Can Plugging a Tire with a Rubber Strip Be Used Long-Term?

Vacuum tires plugged with rubber strips can generally last 3-5 months, and if repaired well, they may last one to two years. After that, the damaged area might start leaking again, requiring re-repair or direct replacement. There are several tire repair methods: 1. Rubber Strip Repair Method: Before repairing, puncture the tire again. This is an external hard repair, so it cannot guarantee airtightness and durability. Over time, it is prone to recurrence, posing safety hazards. 2. Hot Patch Repair Method: After heat treatment, the airtightness is better than the first method and more durable. 3. Patch Repair Method: Remove the tire from the rim. If the wound is small and hard to detect, apply soap bubbles to locate it. Once found, sand the area. 4. Mushroom Plug Repair Method: This not only repairs the inner damage of the tire but also fills the damaged area of the tire body through the adhesion of the root and the tire, making it sturdy and reliable.

What to Do When Car Key Remote Control Fails?

Every remote key comes with a mechanical key, which can be used to unlock the car door. There are three main reasons why a car key remote control might fail: 1. Low battery power: A dead battery can also cause symptoms similar to remote control failure. In this case, simply replacing the key battery should resolve the issue. 2. Remote function failure: Due to sealing issues, the internal components may become damp, dirty, or oxidized over time, causing the buttons to gradually lose sensitivity. To fix this, open the key casing, remove the battery, and use a cotton swab dipped in alcohol to clean the button contacts on the internal circuit board. After cleaning, reassemble and test if the remote works normally. 3. Poor circuit board contact: This situation requires soldering. However, since the solder points are very small and most car owners lack tools like a soldering iron, it is recommended to take the key to a specialized electronics repair shop or a mobile phone repair service for professional handling.

What gear should be engaged when parking a car downhill?

For manual transmission vehicles, it is more appropriate to maintain the gear between second and third when going downhill. On steep slopes, the lower the gear, the safer it is. The key factor in selecting the gear for a manual transmission when going downhill lies more in the angle of the slope. Additional information: 1. Do not turn the steering wheel sharply on downhill sections, as the high inertia and speed, combined with improper steering wheel use, can easily lead to a rollover. 2. If there is an uphill section after the downhill, prepare to accelerate as you approach the bottom of the slope by releasing the brake pedal in time and shifting to a higher gear at the appropriate moment. 3. Maintain a distance of more than 50 meters from the vehicle in front. If the slope is too long and the vehicle's inertia is high, the distance between vehicles should be appropriately increased.

How to Remedy the Use of Poor-Quality Gasoline?

If poor-quality gasoline has been added, it is necessary to completely remove the remaining gasoline from the fuel tank and refill it with higher-quality gasoline. In addition, the fuel injectors and combustion chamber should be cleaned, and the fuel filter and fuel pump should be replaced. Otherwise, excessive impurities can easily cause blockages. Only by doing so can all the poor-quality gasoline be thoroughly removed. Additional Information: 1. It is best to leave the task to professionals at a 4S shop or auto repair shop, as improper handling may damage the engine. 2. Do not underestimate the impact of poor-quality gasoline. It not only reduces the car's power output but also causes noticeable vibrations and unusual noises during idling. Moreover, poor-quality gasoline often lacks good anti-knock properties, making the engine prone to knocking. Over time, this can lead to significant carbon buildup, increasing fuel consumption. In severe cases, it can damage the catalytic converter, resulting in very high repair costs.
