Can a deformed tire still be used?

Do tire cord webs need oiling?

Tire cord webs need oiling. The cords inside tires are called tire cords. Related introduction: Viscose tire cords: Resistant to fatigue and heat with good dimensional stability, but they have the disadvantage of being prone to moisture absorption, which reduces strength after absorption. Mainly used in radial passenger car tires. Polyamide tire cords: High strength with good impact and fatigue resistance, but poor dimensional stability and adhesion to rubber. During use, they must undergo dipping and heat stretching treatment to improve dimensional stability and adhesion. Widely used in tires for trucks, aircraft, as well as in belts and hoses. Polyester tire cords: High strength with large initial modulus, good thermal shrinkage and dimensional stability, but they generate high heat during fatigue, are prone to amination and hydrolysis which reduce strength, and are difficult to bond with rubber. To improve adhesion, surface activation treatment and dipping are required. Widely used in passenger car tires. Aromatic polyamide tire cords: High strength and modulus with better high-temperature resistance and dimensional stability, but high cost and poor adhesion to rubber. Suitable for high-performance tires in premium cars, military vehicles, aircraft, etc.

Why is the Mercedes-Benz air conditioning not cooling?

When the air conditioning fails to cool, it is usually due to issues with internal components. The specific reasons are as follows: 1. Refrigerant: Insufficient refrigerant, leaks in the pipeline, or a faulty refrigerant pressure sensor can cause the pressure in the refrigerant circulation loop to drop too low. This activates the self-protection mechanism of the air conditioning compressor, automatically shutting it off and resulting in no cooling. 2. Clogged air conditioning condenser: Common symptoms of this issue include the dashboard displaying a high coolant temperature warning and poor cooling performance. This often occurs in vehicles frequently driven in dusty conditions or in areas with abundant willow catkins during spring and summer, which can dirty the condenser. 3. Evaporator: The evaporator temperature is too low or the evaporator temperature sensor is faulty. For example, if the evaporator temperature is too low, which often happens after prolonged highway driving in summer, it can cause the high and low-pressure lines of the air conditioning system to freeze, leading to no cooling. The solution is to avoid using the recirculation mode and switch to fresh air mode. 4. Temperature sensor faults: a. Faulty outdoor temperature sensor: This sensor detects the ambient temperature outside the vehicle and provides the comfort control unit with external temperature data. The unit then compares the inside and outside temperatures to regulate the cabin temperature. If the outdoor temperature sensor or its related wiring and connectors malfunction, the comfort control unit cannot accurately compare and determine the temperature. b. Faulty indoor temperature sensor: Similar to the outdoor temperature sensor issue. 5. Other faults: a. Issues with the air blend door, its motor, or related wiring: For example, if the air blend door is stuck, even if the cooling function is working, cold air can only escape through small gaps, making effective cooling impossible. b. Electrical faults in the air conditioning control unit. c. Compressor-related faults: Mechanical failure of the compressor itself; wiring harness issues; for air conditioning systems equipped with variable-frequency compressors, problems with the variable-frequency valve can cause the system to stop cooling after the vehicle is exposed to intense sunlight. d. The compressor enters a self-protection shutdown state. e. When the engine control unit (ME) detects a high power demand, it may shut off the compressor.

What is the average lifespan of a car in kilometers?

In China, vehicles reaching 600,000 kilometers will be guided toward mandatory retirement by national regulations. Theoretically, there is no upper limit to a car's lifespan in terms of mileage. With proper maintenance from exterior to interior, the longest-serving car currently has exceeded 50 years of operation, accumulating nearly 5 million kilometers. However, according to Article 7 of China's latest Compulsory Vehicle Retirement Standards, the government guides the retirement of vehicles that reach certain mileage thresholds—meaning the standard lifespan for ordinary passenger cars is set at 600,000 kilometers. Automotive lifespan definition: A car's service life refers to the continuous mileage or duration from when it leaves the factory and enters operation until its performance gradually declines due to component aging, wear, and other damages, leading to increased operational costs until it becomes unfit for continued use. In summary, a vehicle's usable lifespan is constrained by three factors: 1) legally mandated age limits, 2) legally prescribed mileage caps, and 3) annual inspections (if the vehicle fails to meet standards and cannot legally operate on roads, it becomes equivalent to being scrapped). While cars have no inherent design lifespan—theoretically allowing indefinite use with adequate upkeep—practical usage remains bound by national laws. Every country implements corresponding compulsory vehicle retirement standards for motor vehicles.

How Long Does a Regular Car Maintenance Take?

Car minor maintenance typically takes 30 to 40 minutes, while major maintenance requires 2 to 3 hours. Before maintenance, you can make a phone reservation in advance to avoid long waiting times. Here is more information about car maintenance: 1. Car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent failures, and extend the service life. 2. Minor maintenance generally refers to the routine maintenance items performed at the manufacturer's specified time or mileage after the car has traveled a certain distance to ensure vehicle performance, mainly including oil and oil filter replacement. 3. Major maintenance refers to the routine maintenance performed at the manufacturer's specified time or mileage, which includes replacing the oil, oil filter, air filter, and fuel filter.
