How to Deal with Transmission Locking?

Why is the car charging the phone slowly?

The main reason for slow USB charging in vehicles is that most vehicle USB ports are designed to provide a data transfer interface between the vehicle and the phone, not for charging the phone. Therefore, in this case, it is best to use a power bank to charge the phone. Solutions for slow USB charging in cars: Use a power bank or other portable charger to charge the phone, or purchase an additional cigarette lighter adapter for phone charging. If you choose to buy a cigarette lighter adapter for phone charging, be careful when using this charger. Avoid connecting the phone when the engine starts and overloading the cigarette lighter power supply. Since the power supply of this type of charger is difficult to control, it is prone to spontaneous combustion. Precautions for using USB ports: You must charge only when the car engine is started to avoid damage to the charger due to unstable vehicle power supply. Do not connect too many electrical devices to avoid overloading and damaging the car battery and alternator. Do not use the USB port during thunderstorms to avoid lightning strike accidents. Do not use the USB port in a humid environment, as rust or water stains may cause the USB device to fail to connect properly.

Should You Engage the Handbrake or Shift to Neutral First After Stopping in Driving Test Part 3?

After stopping in Driving Test Part 3, the safest practice is to first shift the gear to neutral, then engage the handbrake. Shifting to neutral first offers certain advantages. If you suddenly realize that the test vehicle is over 50 centimeters from the road edge line after shifting to neutral—which clearly violates test requirements—you still have a chance to adjust by simply shifting back to first gear and maneuvering again. Additionally, with the gear in neutral, if your left foot accidentally releases the clutch, the vehicle won't lurch forward, significantly reducing the likelihood of failing the test. Important Notes: If you engage the handbrake first, subsequent actions can no longer be performed. Moreover, many students subconsciously release the clutch immediately after engaging the handbrake, causing the test vehicle to jerk forward. Once the system detects this, it will result in an automatic failure. Therefore, the optimal sequence is to shift to neutral first, then engage the handbrake. After turning off the engine, unfasten the seatbelt, check for oncoming traffic by looking over your shoulder, and only open the door and exit when it's safe. About Driving Test Part 3: Driving Test Part 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviated term for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle being licensed for.

What are the reasons for the failure of car power windows to move up and down?

Solutions for power windows that cannot move up and down: 1. Reset the window lifting system: Generally, the inability of car windows to move up and down is caused by the disconnection of the battery, or the power or ground wire of the window control module being disconnected during vehicle maintenance. This can be resolved by resetting the window lifting system. Start the car, operate the window switch, hold the switch for more than 3 seconds after the window reaches the top, then release and immediately press and hold the switch again to initialize the window lifting system. If you are unsure, it is recommended to seek professional technical assistance. 2. Clean the dirt in the glass guide channel: If the car glass is tilted or difficult to move up and down, it may be due to excessive dust or dirt in the glass guide channel, increasing resistance during the lifting process. The owner can use a wet towel wrapped around chopsticks to clean inside the guide channel by moving it up and down, and continuously wash the towel to remove the dirt until the guide channel is clean. After cleaning, check if the window glass returns to normal operation. 3. Directly replace the window regulator switch: The window glass switch is used frequently and is more likely to be damaged. If the glass cannot move up and down, the car window regulator can be replaced. Those with strong DIY skills can replace it themselves, but it is still recommended to visit a 4S shop for replacement.

Does Every Car Have a Three-Way Catalytic Converter?

Not all cars are equipped with a three-way catalytic converter. In the early years in China, vehicles produced that did not meet the National II emission standards lacked this component. The three-way catalytic converter is an external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO emitted from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Below are the reasons for the failure of a three-way catalytic converter: Excessive Temperature: At room temperature, the three-way catalytic converter does not possess catalytic capabilities. Its catalyst must be heated to a certain temperature to gain oxidation or reduction abilities. Typically, the light-off temperature of the catalytic converter ranges between 250–350 degrees Celsius, with normal operating temperatures generally between 400–800 degrees Celsius. During operation, the catalytic converter generates a significant amount of heat, and higher loads result in higher oxidation temperatures. When the temperature exceeds 1,000 degrees Celsius, the catalyst coating inside can sinter and fail, also increasing the risk of vehicle fires. Therefore, it is crucial to control factors that cause exhaust temperature to rise, such as delayed ignition timing, misfiring, or incorrect ignition sequences, as these allow unburned fuel mixture to enter the catalytic converter, leading to excessively high exhaust temperatures and impairing its efficiency. Chronic Poisoning: The catalyst is highly sensitive to elements such as sulfur, lead, phosphorus, and zinc. Sulfur and lead originate from gasoline, while phosphorus and zinc come from lubricating oil. These four substances, along with their oxide particles formed during combustion in the engine, tend to adhere to the catalyst's surface, preventing it from contacting exhaust gases and thus losing its catalytic function—a phenomenon known as poisoning. Carbon Buildup: When a car operates under low-temperature conditions for extended periods, the three-way catalytic converter cannot activate, and carbon particles from the engine exhaust adhere to the catalyst's surface. This prevents contact with CO and HC, eventually clogging the converter's pores and reducing its conversion efficiency. Exhaust Deterioration: The catalytic converter has a limited capacity for pollutant conversion, so it is essential to minimize raw emissions through internal purification technologies. If the concentration or total volume of exhaust pollutants is too high—such as an overly rich air-fuel mixture—it can impair the catalytic converter's ability to transform pollutants, lowering its efficiency. Additionally, when excessive amounts of HC and CO enter the catalytic converter, they trigger intense oxidation reactions, generating excessive heat that can damage the converter due to overheating.

Can a Seized Car Still Be Driven?

A seized vehicle can still be driven if it is not under impoundment, and it can undergo normal annual inspections and insurance payments. However, it cannot be sold, mortgaged, or repurposed for other uses. Below are the specific reasons: Legal Basis for Driving a Seized Vehicle: According to Order No. 124 of the Ministry of Public Security, it explicitly prohibits certain vehicle-related procedures during the seizure period, such as registration, modification, transfer, mortgage release, deregistration, and pledge release. However, it does not prohibit annual inspections, temporary license plates, or replacement of license plates and certificates. The "Road Traffic Safety Law" does not stipulate that seized vehicles are prohibited from being driven on the road. Additionally, based on the nature of seized vehicles, a car that is merely seized can still be driven legally. Cases Where a Seized Vehicle Cannot Be Driven: If the vehicle is both seized and impounded, it cannot be driven on the road. Methods to Lift the Seizure: If a seized vehicle is not resolved within the stipulated time, it may be locked at any time. As long as the seized vehicle is not physically impounded, it can still be driven, but changes or transfers are not allowed. To lift the seizure, the respondent must fulfill the judgment or provide other guarantees. If the judgment has been fully executed, an application can be made to the court to lift the seizure. Once the court issues a release ruling, the ruling document can be taken to the vehicle management office to complete the release process.
