What causes the abnormal noise in the rear wheels of the Geely GL?

Geely GL rear wheel abnormal noise causes are as follows: Tire issues: Pebbles stuck in the rear tire treads can cause a "clicking" noise during high-speed driving. This noise changes frequency with vehicle speed - faster speed leads to higher frequency, slower speed results in lower frequency. Brake pad problems: When brake pads wear to their limit, the metal indicators rubbing against the brake discs create significant noise. Additionally, harder brake pad materials can also cause abnormal sounds. Bearing wear: Worn or loose wheel bearings in the rear wheels can also produce abnormal noises.

What Causes a Car to Shake and Lose Power?

The reasons for engine shaking and power loss in a car are as follows: 1. Damaged spark plugs: If the spark plugs are damaged, the gap between the electrodes may wear out, leading to insufficient spark and incomplete combustion of the air-fuel mixture, resulting in shaking during acceleration. Additionally, cracks in the ceramic part of the spark plug can cause misfiring, leading to a cylinder not working properly and causing shaking during acceleration. 2. Poor fuel quality: Low-quality gasoline can result in poor atomization by the fuel injectors, leading to incomplete combustion of the air-fuel mixture in the cylinders and causing the engine to shake and lose power. It is recommended to use higher-octane gasoline after emptying the current tank and perform a fuel system cleaning. 3. Unstable fuel pressure: If you have already cleaned the engine carbon deposits, changed the oil and spark plugs, but still experience shaking at idle, it is advisable to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can cause the car to shake. In such cases, check the fuel pressure and replace components if necessary.

What is the reason for the diesel fuel injection vehicle not shutting off when the key is turned off?

This is an issue with the solenoid valve. Diesel engines should have a fuel solenoid valve. When the key is turned off, the solenoid valve should cut off the diesel fuel supply, causing the vehicle to shut off. If the vehicle does not shut off when the key is turned off, it indicates that the solenoid valve is not sealing the fuel line, allowing the engine to continue running. Additional information: 1. Principle: A solenoid valve is an industrial device controlled by electromagnetism, used as a basic automation component to control fluids, belonging to actuators, and not limited to hydraulic or pneumatic systems. It is used in industrial control systems to adjust the direction, flow, speed, and other parameters of the medium. Solenoid valves can work with different circuits to achieve the desired control, ensuring both precision and flexibility. 2. Types: There are many types of solenoid valves, each serving different functions in control systems. The most commonly used include check valves, safety valves, directional control valves, and speed regulating valves.

Can I go for the vehicle annual inspection in the same month if the validity period ends in July?

Yes, vehicles can undergo inspection and apply for annual review within 3 months before the annual inspection date. Here is relevant information: 1. Timing: It is best to go two months or more than one month in advance. Avoid waiting until there are only a few days left before the inspection expires. Additionally, before the 10th of each month, inspection stations have relatively fewer appointments, making it an ideal time to avoid queues. The number of vehicles increases from mid-month, and the end of the month is the peak period. 2. Emissions test: First, queue up and pay the inspection fee at the payment window, then wait for the test. Before the test, staff will conduct an initial check, mainly verifying whether the engine number matches the vehicle registration certificate, followed by a brief visual inspection of the exterior and condition of the vehicle. Then, fill out the emissions test form. During the test, an inspector will drive the vehicle onto the testing line. Generally, new vehicles pass easily. Once you receive a qualified emissions test form, you can pay at the window and collect the emissions compliance sticker. If the vehicle fails, it must be adjusted at a repair shop and retested.

Should You Patch or Replace a Tire After a Nail Puncture?

If the nail punctures the tread, it can be repaired and continue to be used. If the nail punctures the sidewall, it is recommended that drivers directly replace the tire with a new one. Tires are the only components of a car that come into contact with the ground, and they are crucial for the vehicle's driving stability and safety. If the sidewall of a tire is punctured, it is advisable not to patch it but to replace it with a new tire instead. Additional relevant information is as follows: 1. Tires are made of rubber, and it is inevitable that they will be punctured by sharp objects while driving daily. When a tire is punctured, you should pull over to a safe location and replace it with the spare tire. It is recommended to replace tires every four years, as they are rubber products and will age over time. 2. Even if the mileage is low within four years, replacement is still necessary. When purchasing tires, always check the production date, as tires will age even if they are not used for a long time. The production date of a tire is usually indicated by a four-digit number, which is marked on the sidewall of the tire.

What is the Voltage of a Private Car Battery?

Generally, private car batteries are either 12V or 24V, while large vehicles typically use 24V batteries. These batteries are usually lead-acid batteries, primarily made from lead and its oxides. Precautions for Charging a Car Battery: First, adjust the battery's liquid level to the specified height using distilled water or a dedicated battery replenishing fluid. Before charging, connect the battery to be charged according to the rated voltage and current of the charging equipment. The total voltage of batteries connected in series should not exceed the rated voltage of the charging equipment. The charging current for constant current charging is selected based on the battery's capacity. Constant current charging is carried out in two stages. The charging current in the first stage is one-tenth of the battery's rated capacity, and in the second stage, it is one-twentieth of the battery's rated capacity. After charging the battery, check the density of the battery's electrolyte. During charging, the current should not be too large—keep it below 2A—and the voltage should not exceed 14V. The charging time should not exceed 12 hours.
