Will parking on grid lines definitely be captured by cameras?

Parking on grid lines will definitely be captured by cameras. Reason: Because the principle of capturing parking violations on grid lines is to take photos after the vehicle has been stationary for approximately 3 to 10 seconds. Once the photos of the illegal parking are captured, they will be uploaded to the traffic police's violation system and submitted to the relevant departments for review. If it is indeed an illegal parking act and not due to other reasons, the driver will definitely be penalized. Reasons why parking on grid lines is prohibited: Grid lines are generally set up at intersections with traffic lights or at entrances and exits of schools, institutions, hospitals, fire stations, and other special areas. These are all relatively unique road sections. Therefore, parking is prohibited to avoid vehicles occupying these areas in advance, which could lead to traffic congestion or hinder normal access to certain special locations.

How Often Should an External Fuel Filter Be Replaced?

External fuel filters are generally recommended to be replaced every 20,000 to 30,000 kilometers. Function of Fuel Filters: The primary function of a fuel filter is to filter the gasoline in the vehicle. After prolonged use, impurities in the gasoline can reduce the filter's efficiency. The importance of gasoline for a car is self-evident. Just like food for humans, gasoline is the driving force that propels the car forward. High-quality gasoline ensures better performance of the engine and fuel pump. Conversely, gasoline with excessive impurities can disrupt normal vehicle operation, making regular filter replacement essential. Replacement Interval for Fuel Filters: The exact replacement interval depends on the quality of the gasoline used. If the gasoline contains fewer impurities, delaying the replacement slightly is acceptable. However, if low-quality gasoline is frequently used, it's advisable not to wait until 30,000 kilometers. In such cases, consider replacing the filter as early as 20,000 kilometers. This also highlights how significantly gasoline quality impacts a vehicle's performance.

Can a Used Car with Temporary License Plate Travel to Another Province?

It depends on the type of temporary license plate issued. One type is the temporary license plate for administrative jurisdictions, which has a sky-blue background with black characters and black borders, and is not allowed to travel to other provinces. The other type is the temporary license plate for cross-administrative jurisdictions, which has a brown-yellow background with black characters and black borders, and this type is permitted to travel to other provinces. Validity Period: Temporary license plates have a validity period, with a maximum of 30 days, and for new cars, it must not exceed 15 days. Therefore, it is necessary to apply for a formal license plate from the vehicle management authority within the validity period. Driving with an expired temporary license plate may result in the vehicle being impounded and a deduction of 12 points from the driver's license. Placement Requirements: There are usually two temporary license plates, and their function is almost the same as that of formal license plates. However, their placement differs. One temporary license plate should be placed on the lower left or right corner of the front windshield, and the other must be placed on the lower left corner of the rear windshield. They should not be placed randomly.

What are the signs that spark plugs need to be replaced?

Symptoms indicating that spark plugs need replacement: The car exhibits difficulties in starting, reduced power, excessive exhaust emissions, and increased fuel consumption. Severe spark plug damage may show signs such as blistering at the tip, black streaks, cracking, or electrode melting. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe their appearance to assess their condition. A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burning. If the spark plug is covered in oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing blistering, black streaks, cracking, or electrode melting, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the air-fuel mixture is too rich, with oil creeping up.

What Causes Abnormal Noises in Cars?

Abnormal noises in cars can be attributed to the following reasons: Body Noises: Body noises are the most common and are usually caused by insufficient body stiffness. Long-term aggressive driving or frequent travel on bumpy roads can lead to slight deformation of the car's steel frame. The most direct impact is abnormal collisions or friction between the doors and the car body. Additionally, abnormal friction at welding or screw points can also cause noises. Some cars may have louder wind noise, which is partly related to the car's design. Interior Noises: Interior noises are very common and can originate from multiple areas, such as loosely installed trim panels, a loose glove compartment, or impacts from seatbelt buckles. Brake Noises: If a "squeaking" sound occurs when braking, it is often due to excessive wear of the brake pads, creating unwanted gaps. Improper material use or deformation of the brake discs, as well as unqualified hardness, porosity, friction characteristics, or compression characteristics of the brake pads, can also cause noises. Generally, the lifespan of front brake friction pads is 30,000 kilometers, while rear brake friction pads last up to 120,000 kilometers. Suspension Noises: The suspension system operates continuously while driving, and the rubber bushings between the shock absorbers and various links will inevitably wear out. When these bushings age or fall off, abnormal metal collision sounds may occur. If the shock absorber is damaged, a "thumping" or "clicking" sound may be heard on bumpy roads. Tire Noises: Tire noises are usually tire-related and vary in intensity depending on driving speed, tire type, tire pressure, and road conditions. A low "thudding" sound often indicates tire tread deformation, bulging, severe wear, or insufficient pressure. A "tapping" sound may suggest small stones or nails stuck in the tread. If a metal collision or friction sound comes from the wheels while driving, it could be due to damaged shock absorbers or bearings. These issues should be addressed promptly, as even a simple nail puncture can be dangerous. Steering Wheel Noises: Noises may occur when turning the steering wheel. If the noise appears when the wheel is halfway turned, it is likely due to the steering gear. If the noise occurs when the wheel is fully turned, the source may be harder to pinpoint. A common diagnosis at a 4S shop is friction from the steering tie rod ball joint rubber sleeve. Other causes include leaking steering gear dust covers, loose or aged power steering belts. Engine Compartment Noises: Engine compartment noises are more complex and require thorough inspection. A sharp "screeching" or belt whining noise is usually caused by belt slippage. A hissing sound may indicate blockages or breaks in the exhaust system or vacuum tubes. If metal friction noises occur while the engine is running, it could be due to damaged components like the alternator or water pump. Transmission Noises: If a "rustling" sound is heard from the transmission while driving, or a whistling sound during gear shifts, it may be due to worn transmission bearings or gears, or bearing spots. Noises during acceleration or gear shifts may indicate the presence of metal particles in the transmission fluid, suggesting excessive wear of components like transmission bands or clutches.

What Causes the Wiper to Make Noise?

The reasons for the wiper making noise are: Long-term use leading to aging and hardening; foreign objects stuck between the wiper blade and the windshield; friction in the wiper linkage bushing; malfunction of the wiper motor. The solutions for a noisy wiper are: Directly replace the wiper blade; inspect and clean any foreign objects under the wiper blade or wiper; check the wiper arm or linkage bushing; have a detailed inspection at a professional repair shop. Precautions for using the wiper are: Replace or clean the wiper blade promptly when severe wear or dirt is noticed; wet the windshield with water before checking the wiper's operation; after turning off the wiper switch, the wiper blade should return to the lower side of the windshield and stop.
