Do Motorcycles Need to Be Scrapped?

Motorcycles must be scrapped according to the provisions of Article 5, Clause 11 of the "Mandatory Scrapping Standards for Motor Vehicles": The service life of a three-wheeled motorcycle is 12 years, with a mileage of 100,000 kilometers; other motorcycles have a service life of 13 years, with a mileage of 120,000 kilometers. There are four criteria for mandatory scrapping: Reaching the specified service life; After repair and adjustment, still failing to meet the national safety technical standards for in-use vehicles; After repair, adjustment, or the adoption of control technology, still failing to meet national standards for pollutant emissions or noise from in-use vehicles; Failing to obtain the motor vehicle inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection period. Motor vehicle scrapping process: 1. The vehicle owner applying for scrapping and renewal must fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, Scrapping Approval Application Form" in duplicate and affix the owner's seal. 2. Apply at the registration and acceptance counter. For vehicles that have reached the scrapping age, a "Vehicle Scrapping Notice" will be issued. For vehicles that have not reached the scrapping age but are deemed to meet the scrapping standards after inspection by the motor vehicle inspection counter, a "Vehicle Scrapping Notice" will be issued. 3. The vehicle owner can choose a qualified recycling company to dismantle the vehicle based on the "Notice". 4. The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. 5. The vehicle owner must submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection counter for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed after approval according to regulations.

What Causes Automatic Shutdown Due to Low Rail Pressure?

Introduction to the causes of automatic shutdown due to low rail pressure: Air leakage in the low-pressure fuel circuit: Damaged fuel pipe joints or improper installation. Blockage in the low-pressure fuel circuit leading to poor fuel supply: Such as clogged filters, blocked fuel pump inlet screens, or bent intake pipes. Leakage in the high-pressure fuel circuit causing excessively low rail pressure: Such as excessive injector return flow, nozzle seat leakage, rail pressure relief valve seat leakage, or fuel pump plunger wear and leakage. Fuel pump malfunction: Such as stuck metering units, gear pump failure, or stuck or constantly open overflow valves. Low fuel level in the tank: This can also trigger the fault, leading to automatic shutdown due to low rail pressure.

Is It Normal for the Steering Wheel to Make a Whining Sound?

When turning the steering wheel while driving, a whining sound may occur due to friction between the spiral cable polyester film inside the steering wheel and the combination switch or the steering wheel itself. Prolonged wear could potentially lead to airbag malfunctions. Lack of Power Steering Fluid: This can cause insufficient lubrication of the power steering pump, resulting in unusual noises. Check if the power steering fluid level is adequate. If it's insufficient, inspect the steering system for potential leaks, such as leaks in the steering gear, hoses, power steering pump, or steering fluid reservoir. Steering Noise While Driving: The noise typically originates from the front suspension outside the vehicle. If it's a sharp squeaking sound, it might be due to excessive or insufficient front wheel toe-in, causing tire scrubbing when turning the wheels non-parallel.

Is a Contract Required When Ordering a Car at an Auto Trade?

Ordering a car at an auto trade requires signing a contract. It is recommended to sign the contract before paying the deposit. The contract should clearly specify the deposit amount, payment deadline, intended car model, transaction price, delivery time, and dispute resolution methods before the actual deposit is paid to ensure the smooth progress of the contract. Relevant regulations: When the debtor fulfills the debt, the deposit shall be deducted from the payment or returned. If the party paying the deposit fails to fulfill the debt or the fulfillment does not meet the agreed terms, resulting in the failure to achieve the purpose of the contract, they have no right to request the return of the deposit. If the party receiving the deposit fails to fulfill the debt or the fulfillment does not meet the agreed terms, resulting in the failure to achieve the purpose of the contract, they shall return double the deposit. Precautions for picking up the car: First, check the production date of the vehicle. Then, mainly inspect the body paint, especially the four corners, all lights and onboard electronics, the cooling effect of the air conditioning, engine noise and vibration, the four tires, and whether the spare parts in the trunk are complete. The mileage on the dashboard should not exceed 30. Only when all these are qualified can the payment be made. It is necessary to obtain the vehicle purchase invoice, the compulsory insurance policy, and the commercial insurance policy of the vehicle.
