Why does the wiper jump on the coated windshield?

It is probably because the wiper is too hard. Try replacing it with a softer frameless wiper. After the glass is coated, it becomes smoother, but its adhesion also increases. If the adhesion between the wiper and the glass is too strong, the wiper will jump. For example, it's like sticking a coin to an incense burner in a temple. Below is some relevant information: Waterproof function: Rainwater falling on the treated car glass will quickly form small water droplets under the effect of the protective layer. When the droplets grow large enough, they will slide down the glass due to gravity, taking away dust from the glass and effectively cleaning it. Anti-freeze function: The treated glass has a protective layer, preventing snow or fog water from freezing solidly on the glass in winter. Snow accumulated on the glass can be easily removed, saving the trouble of clearing it and reducing waiting time.

What problems will occur if the ball joint rubber boot is damaged?

The following phenomena will occur if the suspension rubber boot is damaged: Specific phenomena: When passing over speed bumps, cobblestone roads, or dirt roads, you will hear a "clanging" metal knocking sound. On roads with significant potholes, the noise will persist continuously. If the damage is quite severe, it will continuously transmit minor vibrations to the steering wheel. The function of the car shock absorber rubber boot: The car shock absorber rubber boot is made of plastic rubber and serves as a buffer and shock absorber. When passing over speed bumps with the suspension at full compression, it helps lift the body slightly upward after the tires fully land, providing a slightly upward sensation and excellent comfort. It also provides sound insulation, alleviates tire noise caused by the contact between the tires and the ground, and reduces direct impacts on the car when the tires encounter bumps.

Why does the car shake violently when it is just started?

The reasons for severe shaking when the car is just started are poor fuel quality, carbon deposits in the engine valves and intake pipes, and spark plug failure. The specific reasons are as follows: Poor fuel quality: Inferior fuel has poor volatility. When the engine block temperature is low during a cold start, the fuel injected into the cylinders cannot mix sufficiently with air, resulting in difficulty starting and severe body shaking. Carbon deposits in engine valves and intake pipes: Carbon deposits can absorb an appropriate amount of fuel, causing the electronic control unit to misjudge, failing to provide the power needed for the car to start, leading to shaking. Spark plug failure: The gap between the spark plug electrodes gradually increases, reducing ignition energy and causing poor fuel atomization, which results in body shaking immediately after starting.

Does the Li ONE engine provide power?

Li ONE's engine cannot directly drive the wheels. Here is relevant information: Powertrain: It adopts a range-extender powertrain mode combining a 1.2T three-cylinder engine with front and rear motors. In addition to using some physical insulation materials, the engine also utilizes a double-layer front windshield and front-row bilateral glass to suppress various noises. Working principle: The principle is that the engine is matched with the electric motor, driving the wheels through electric transmission. The engine only serves as a range extender, converting thermal energy into electrical energy to provide power output for the electric motor. In urban driving conditions, the most economical pure electric mode is used, while on highways, the engine will inevitably intervene. Low-speed cruising conditions are conducive to the engine operating at its highest efficiency, achieving a balance between power and fuel economy.

What is an ETC On-Board Unit?

ETC stands for Electronic-Toll-Collection, which refers to the electronic toll collection system. To apply for it, the vehicle owner needs to provide original and photocopied versions of their valid ID card and vehicle registration certificate. If the application is handled by someone other than the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page stamped with the most recent annual inspection seal. Additionally, a bank card for deducting highway toll fees is needed. Applicants must be between 18 and 60 years old, and the vehicle must be registered under their name. Generally, an ETC device can last 2-3 months on a single charge. The ETC user manual does not specify how long a single charge lasts. For vehicle owners who do not frequently use ETC, it is recommended to charge the ETC device every three months. For wired ETC devices, if they are not used for a long time, it is advisable to charge them once a month to prevent the battery's lifespan from being affected by self-discharge. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay the toll. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-effective: Lowers costs by reducing the frequency of vehicle starts and stops, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Increased efficiency: ETC lanes can theoretically improve traffic efficiency by 2-3 times, making traditional ETC more advanced, faster, and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Will the 12123 Automatically File the Record After Passing Subject 4?

After passing Subject 4, the 12123 will automatically file the driver's license information. When the traffic police 12123 shows that the driver's license has been filed but you have not yet received the physical license, you are still not allowed to drive on the road. You must wait until you have the physical license in hand. According to China's "Road Traffic Safety Law," drivers must carry their driver's license while driving. Failure to do so may result in a fine of 50 yuan, a deduction of 1 point, and even the impoundment of the vehicle. Below is some information about the driver's license: 1. Definition of a Motor Vehicle Driver's License: A legal document issued by the authorities after a person has learned and mastered traffic regulations and driving skills, passed the required tests, and is permitted to drive a certain type of motor vehicle. 2. Examination Subjects for a Motor Vehicle Driver's License: Includes traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving).
