What documents are required for car transfer procedures?

Documents required for car transfer: ID card, vehicle license, original purchase invoice, and sales contract. Below is an introduction to car transfer and its principles: Introduction to car transfer: Vehicle transfer refers to changing the name of the vehicle's owner. When purchasing a used car, apart from checking the car's condition, the most important step is completing the transfer procedures. Principles of car transfer: Every car has a fixed registration, which primarily records the car's owner, address, and some related car parameters. Transferring a car proves that the car belongs to the current owner and has no accidents or violations. If the car has issues, such as being involved in an accident, failing annual inspection, being stolen, or being smuggled, it cannot be transferred through normal procedures.

Does the Three-Way Catalytic Converter Affect Fuel Consumption?

The three-way catalytic converter does affect fuel consumption. Its primary function is to influence vehicle emissions. Lower emissions indicate more complete gasoline combustion, leading to better fuel efficiency. Conversely, if the catalytic converter fails, emissions increase, gasoline cannot burn or be utilized efficiently, and fuel consumption naturally rises. Methods to determine the condition of the three-way catalytic converter: Visual inspection. Examine the exterior of the catalytic converter for any damage or discoloration. Scratches, cracks, or other external marks may indicate prior damage. If there are noticeable gray spots on the protective cover, severe discoloration, or purple marks on the casing, the catalytic converter may have suffered from overheating issues. Check the engine exhaust. Place your hand near the tailpipe outlet to feel the exhaust flow and assess whether the catalytic converter is clogged or if there are exhaust flow issues. Another method is to open the air filter, remove the filter element, and observe if exhaust gases flow backward during rapid acceleration, indicating poor exhaust flow. To evaluate the TWC's condition, also inspect the secondary air injection pump for faults. Use an infrared thermometer. Compare the temperature difference between the front and rear of the TWC using an infrared thermometer. If the temperature difference between the inlet and outlet of the catalytic converter is less than 10°C, the TWC is likely damaged.

What is the reason for the handbrake being pulled up but not able to be released?

It may be due to a failure in the handbrake ratchet mechanism. Here is an introduction to the car handbrake: Introduction: The parking brake, commonly known as the handbrake, functions to provide resistance to the car when parked, preventing it from rolling. The parking brake, also referred to as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. The force of the parking brake is much weaker compared to the service brake, just enough to prevent the car from rolling on a slope. Electronic Parking Brake System: The Electronic Parking Brake System integrates the temporary braking function during driving with the long-term braking function after parking, and achieves parking braking through electronic control technology.

Is Lane-Specific Speed Limit Applicable to Passenger Cars?

Lane-specific speed limits are applicable to passenger cars. Relevant information is as follows: Highway speed limits: The maximum speed limit for small passenger vehicles on highways does not exceed 120 km/h; other vehicles are limited to 100 km/h. On the same road section, the speed difference between small passenger vehicles and other vehicles should not exceed 20 km/h, and the set speed limit must not be more than 20 km/h above the design speed. Lane-specific driving: During adverse weather conditions and on special road sections such as bridges and tunnels, speed limits are determined by on-site speed limit signs. In long tunnels, tunnel clusters, and long steep slope sections on highways, vehicles are required to drive in designated lanes, with all motor vehicles other than small passenger cars keeping to the right lane.

What is the normal tire pressure for a three-wheeled motorcycle?

The normal tire pressure for a three-wheeled motorcycle is 170kpa for the front wheel and 200-220kpa for the rear wheels. Each tire has maximum and minimum pressure limits. Exceeding these limits can lead to the risk of a tire blowout, while insufficient tire pressure can cause premature tire damage. Hazards of overinflated tires: Reduced friction and adhesion of the tire, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more likely to be punctured, leading to internal cracks and blowouts. Hazards of underinflated tires: Increases friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; increases tire deformation, making the sidewalls prone to cracks and generating flexing motion, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground and accelerating shoulder wear.

Which website to buy second-hand rims?

Second-hand rims can be purchased at auto repair shops or professional rim modification stores. However, it is recommended to buy new rims for better quality assurance. Relevant information is introduced as follows: Introduction to rims: The rim is a cylindrical metal component that supports the tire from the inner contour and is mounted on the axle at the center. It is also called wheel rim, steel ring, or hubcap. Rims come in various types based on diameter, width, manufacturing method, and material. Precautions for purchasing second-hand rims: Similar to second-hand cars, second-hand rims may also have certain quality issues when purchased, which cannot be avoided. Therefore, car owners need to improve their ability to identify such problems. After refurbishment, it is difficult to detect defects on the rims with the naked eye, and some cracks can even be concealed. Some rims may even be second-hand or third-hand. The best way to identify refurbished rims is to check the labels on the tires, because refurbished tires no longer have the original production labels and tire codes. Therefore, stickers are an important basis for judging whether a rim is refurbished.
