What Causes the Noise in Car Fan Blades?

The causes of noise in car fan blades are as follows: 1. Deformation of the fan blades in the air conditioning system, it is recommended to replace the fan. 2. Damage to the motor of the fan in the air conditioning system, it is recommended to replace the fan. 3. Excessive impurities in the air conditioning system, it is recommended to clean the air conditioning system. More details are as follows: 1. The car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. The coolant flows inside the radiator core, while air passes outside the radiator. The hot coolant cools down by dissipating heat to the air, and the cold air heats up by absorbing the heat from the coolant. 2. The materials and manufacturing technologies for car radiators have advanced rapidly. Aluminum radiators, with their significant advantages in material lightweighting, are gradually replacing copper radiators in the passenger car and light vehicle sectors. Meanwhile, copper radiator manufacturing technology and processes have made substantial progress, with copper brazed radiators showing clear advantages in engine radiators for buses, construction machinery, and heavy-duty trucks. 3. Overseas passenger cars are mostly equipped with aluminum radiators, primarily for environmental protection reasons (especially in Europe and the United States). In Europe, aluminum radiators account for an average of 64% of new passenger cars. 4. From the perspective of the development prospects of China's car radiator production, brazed aluminum radiators are gradually increasing. Brazed copper radiators are also being applied in buses, trucks, and other engineering equipment.

How much over the speed limit is driving at 170 in a 120 zone?

Driving at 170 in a 120 zone is 20% over the speed limit, which is below 50%. Highway speeding penalties: 1. Within 10% over the limit: no points deducted, traffic police warning. 2. Between 10%-20% over: 3 points deducted. 3. Between 20%-50% over: 6 points deducted. 4. Over 50%: 12 points deducted. Tips to avoid speeding on highways: 1. Use mobile navigation apps properly. 2. Install a radar detector in your car. 3. Watch for speed cameras on gantries. 4. Always monitor your speedometer during highway driving, as it's easy to speed unintentionally - make this a habit.

Should the Air Brake Not Be Continuously Pressed?

Air brakes should not be continuously pressed because doing so will deplete the air in the air tank, leading to a loss of braking capability. It also increases the workload of the engine, causing engine vibration. Reasons why air brakes should not be continuously pressed: The principle of air brakes involves using compressed air from the storage tank to inflate the brake chamber, which pushes the brake shoes to achieve braking. Continuously pressing the brake pedal will reduce the air pressure in the tank, eventually leading to insufficient pressure and an inability to brake properly. Additionally, truck brakes are crucial for safety, which is why most truck drivers ensure the air pressure in the air brake system reaches 5-6 Bar before setting off. Consequences of continuously pressing the air brake: Air brakes use a cylinder regulator valve to create resistance against the engine's operation, thereby reducing engine speed and slowing the vehicle. Keeping the exhaust brake engaged for prolonged periods increases the engine's workload, resulting in engine vibration. In severe cases, it can cause the cylinder regulator valve to be forced open and damaged. How the spring brake (parking brake) works: The air pump, driven by the engine, compresses air into high-pressure gas stored in the air tank. One air tank is connected to the brake master cylinder via pipelines. When the driver presses the brake pedal, the upper air circuit opens first, and high-pressure gas from the air tank is transmitted to the relay valve.

What to do if the driver's license renewal has expired?

Solution for expired driver's license renewal: The motor vehicle driver should bring the required materials to the vehicle management office where the driver's license was originally issued to apply for renewal. The vehicle management office will process the renewal within one working day after approval. Required materials for renewal include two copies of ID card, two recent 1-inch color photos without hats, original ID card, original driver's license, and a medical examination certificate from a county-level or above hospital. Renewal and inspection must meet the following conditions: Holders of large passenger vehicle, tractor, city bus, medium-sized passenger vehicle, or large truck driver's licenses must have no demerit points in the current scoring cycle, or holders of other types of driver's licenses must have less than 12 demerit points in the current scoring cycle; Holders of large passenger vehicle, tractor, city bus, medium-sized passenger vehicle, or large truck driver's licenses who have demerit points in the current scoring cycle, as well as holders of other types of driver's licenses who have been involved in a traffic accident resulting in death with equal or greater responsibility but have not had their driver's license revoked, must have completed the inspection education; The applicant must have no pending road traffic safety violations or traffic accidents; The applicant's physical condition must meet the driving license requirements; The driver's license must not be seized, detained, temporarily suspended, revoked, canceled, or withdrawn by law.

What are the impacts of a car without a catalytic converter?

A car without a catalytic converter will cause air pollution. Additional information is as follows: 1. Vehicle exhaust: The three harmful gases in vehicle exhaust have extremely slow chemical reaction rates with each other without a catalytic converter, and some reactions cannot even occur. 2. Catalytic converter: There are no moving parts inside, and all cleaning operations are completed through ingenious chemical reactions. The interior of the catalytic converter consists of a thick substrate with a fine grid-like cross-section, coated with precious metals such as platinum, palladium, and rhodium. 3. How a catalytic converter works: The precious metals act as catalysts in the actual reactions. Whether they are emissions, gasoline, diesel, or engine oil, they can react with these precious metals and quickly transform into less harmful substances primarily composed of nitrogen, carbon dioxide, and water.

Is the new small sedan exempt from inspection for six years?

New small sedans are exempt from inspection for six years. Additional information is as follows: 1. Small sedans are exempt from inspection for the first six years: This means that within six years, there is no need for an on-site inspection. This policy only applies to private passenger vehicles with 5 seats or fewer. 2. Collect the annual inspection sticker every two years during the exemption period: Every two years, the vehicle owner must personally go to the vehicle management office to collect the annual inspection sticker. Bring your ID card, vehicle registration certificate, and valid compulsory traffic insurance policy to apply for a new annual inspection sticker. Starting from the seventh year, an annual on-site inspection is required, and the annual inspection sticker must be collected every year. 3. Scope of vehicles "exempt from inspection for six years": 1. The scope of exempt vehicles includes non-commercial sedans (including large sedans) registered within six years, other small and mini passenger vehicles, and motorcycles. 2. Excluded are vans and vehicles with more than 9 seats (>9 seats).
