What does the radial of a tire mean?

Tire radial, also known as the meridian line, refers to the arrangement direction of the internal cord fabric of the tire at a 90-degree angle to the centerline of the tread, resembling the meridians on a globe. Below is relevant information: 1. Introduction: Radial tires (radial-tire) are a type of tire structure, different from bias tires, arched tires, and pressure-regulating tires. The international code for radial tires is "R", commonly known as "steel-belted tires". 2. Characteristics: The arrangement of the cord fabric in radial tires differs from that in bias tires. In radial tires, the cords are not arranged in a crisscross pattern but are nearly parallel to the cross-section of the outer tire, resembling the arrangement of the Earth's meridians. The cord angle is small, generally 0°, and there are no intersecting points between the cords of the tire body. When the tire is in motion, the stress around the crown increases, causing axial extension and radial cracking of the tire body.

What to Do When the Car Air Conditioning Switch Doesn't Respond?

Possible reasons for sudden car air conditioning failure: 1. Blocked pipelines: causing excessively high pressure or excessively low pressure; 2. Poor heat dissipation; 3. Blocked expansion valve; 4. Insufficient or excessive refrigerant; 5. Compressor not operating. Below are the solutions: 1. Check the refrigerant pressure: If the pressure is too low, the refrigerant is insufficient and needs to be replenished. Insufficient refrigerant will affect the cooling efficiency of the air conditioning. Check whether the blower of the air conditioning system is operating normally and the air volume. If the blower malfunctions, the cold air from the air conditioning system cannot be delivered to the car interior in time, resulting in no cold air from the air vents. 2. Check if the evaporator of the air conditioning system is too dirty: If the evaporator surface is too dirty, the cold air from the air vents will decrease, as the cold air is mainly produced by the evaporator. Check for leaks in the condenser pipelines, as leaks will prevent the air conditioning system from cooling. Inspect the condenser of the air conditioning system to see if its surface is too dirty, as a dirty condenser will affect heat dissipation and thus the operation of the air conditioning system. 3. Refrigerant malfunction: The refrigerant's circulation in the pipelines depends on the compressor's operation. If the compressor cannot engage due to abnormal refrigerant pressure, circuit failure, damaged temperature sensor, or burned-out electromagnetic clutch, cooling will be insufficient. It is recommended to replace the temperature sensor or electromagnetic clutch.

What is the gear shift lever called?

The lever used for shifting gears in a car is called the gear shift lever or operation lever. Here is some related information: 1. Serpentine Gear Shift Lever: This type of shift lever is more commonly found in Japanese cars. Because it lacks a locking mechanism, the gear positions are designed in a zigzag pattern to prevent mis-shifting, resembling a snake winding around the surface, hence the name "serpentine." The advantage of this type of shift lever is safety. 2. Electronic Gear Shift Lever: Unlike traditional mechanical shift levers, this type directly controls the transmission gears through simulated electronic signals. The benefits include ease of operation—simply pushing up or down to engage the desired gear—and because the entire process is computer-controlled, it prevents damage to the transmission caused by incorrect shifting. From a technical perspective, electronic shift levers offer greater flexibility in terms of position and form, allowing for more versatile designs.

Is it okay if a car drives through water without stalling?

Driving through water is a common situation and generally does not cause damage to the vehicle. Here’s a detailed explanation: 1. Water-fording vehicles: Water reaches the wheels but does not enter the cabin, commonly referred to as water fording. This scenario is quite frequent and typically causes no damage to the vehicle. 2. Water-damaged vehicles: Water reaches halfway up the wheels and enters the cabin, submerging areas below the dashboard (generally called water-damaged vehicles). In such cases, the vehicle's performance may be compromised, but it can still be used after professional repairs. 3. Flood-damaged vehicles: Water levels exceed the wheels, enter the cabin, and submerge the dashboard (commonly called flood-damaged vehicles). These vehicles suffer severe damage to the engine, transmission, and electrical systems, and are not recommended for continued use even after repairs.

What maintenance is required for a sedan at 100,000 kilometers?

Mainly replace the engine oil and oil filter. Below are the relevant details about car maintenance: 1. Engine oil and oil filter replacement: The primary function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter removes impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car requires maintenance every 5,000 kilometers. 2. Air filter replacement: The air filter cleans the air before it enters the cylinders by removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is typically replaced every 20,000 to 25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are part of the inspection items during routine maintenance and should be serviced or replaced based on their condition.

At how many kilometers is a motor vehicle scrapped?

Private vehicles and commercial vehicles have different scrapping mileage standards, as detailed below: Private vehicle scrapping regulations: For family-use 5-seat sedans and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage age limit. When the normal driving mileage reaches 600,000 kilometers, the state will recommend scrapping. In addition to the above-mentioned vehicles, small and mini non-commercial passenger vehicles, large non-commercial sedans, and wheeled special-purpose machinery vehicles also have no usage age limit. Common commercial vehicle scrapping regulations: Small and mini taxi passenger vehicles have a scrapping age of 8 years, medium-sized taxi passenger vehicles have a scrapping age of 10 years, and large taxi passenger vehicles have a scrapping age of 12 years. Public bus passenger vehicles have a scrapping age of 13 years, other small and mini commercial passenger vehicles have a scrapping age of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping age of 15 years; mini commercial trucks have a scrapping age of 8 years, while light and large commercial trucks have a scrapping age of 10 years.
