Is a new car exempt from inspection for 6 years?

New cars are exempt from inspection for 6 years. Here are the details: 6-year exemption for new cars: This means that within the first 6 years, the vehicle does not need to undergo an on-site inspection at a testing station. However, the owner must still perform a periodic check every two years. During the first 6 years, in the second and fourth years, the owner only needs to complete some relevant formalities. In the sixth year, the owner must take the car to the testing station for an on-site inspection and obtain the inspection sticker upon passing. For passenger transport vehicles: Annual inspection is required within the first 5 years; after 5 years, inspection is required every 6 months. For trucks and large or medium-sized non-passenger transport vehicles: Annual inspection is required within the first 10 years; after 10 years, inspection is required every 6 months.

How to Determine if a Car Bearing is Faulty?

To determine if a car bearing is faulty, observe the following signs: noise from the wheel area and excessive heat from the car tire. The main functions of a bearing are to bear loads and provide precise guidance for the rotation of the wheel hub. It handles both axial and radial loads, making it a crucial component. Traditional car wheel bearings consist of two sets of tapered roller bearings or ball bearings combined. The installation, lubrication, sealing, and clearance adjustment of the bearings are all performed on the car production line. The roles of the bearing include: 1. Ensuring the shock absorber rotates with the wheel during vehicle steering, maintaining steering flexibility; 2. The outer ring of the pressure bearing is made of rubber, maintaining a flexible connection between the car body and the shock absorber to prevent road vibrations from being transmitted to the body through the shock absorber during driving.

Is a Long-Term Fuel Trim of -14.7 Rich or Lean?

Long-Term Fuel Trim -14.7 indicates a rich condition. Below is relevant information: 1. Fuel Standard: Generally, the long-term fuel trim parameter ranges from -23% to 16%. A value of 0 means the fuel supply does not require compensation to achieve the correct mixture concentration. A positive value indicates that the injection system needs to inject additional fuel, meaning the engine's air-fuel mixture is lean, and the vehicle may have difficulty starting. A negative value means the fuel injection system needs to reduce fuel delivery to correct an overly rich mixture. Therefore, when the long-term fuel trim is negative, it indicates the vehicle's mixture is too rich. 2. Long-Term Fuel Trim Standard: Typically ±5%. If it exceeds this range, it is highly likely that the engine has a fault. If the vehicle's fuel injectors are clogged, both the fuel injection volume and atomization effect will be poor, resulting in a lean combustible mixture in the engine cylinders.

Is it normal for a new car's exhaust pipe to have a little black residue when touched by hand?

It is not normal for a new car's exhaust pipe to have black residue. However, it is normal for the exhaust pipe to turn black after the car has been driven for some time. Below are the relevant explanations: Poor spark plug performance: When the car is in a cold-start condition, if the spark plugs are not functioning properly, the air-fuel mixture will not burn completely, resulting in large amounts of black smoke. Aging engine: If the engine has been used for too many years, its overall performance will degrade, causing the car to only spray gasoline without properly combining it with air for combustion. This leads to excessive black smoke, which blackens the exhaust pipe. Incorrect engine timing or ignition timing: Such timing discrepancies can prevent oxygen and engine oil from fully mixing and burning.
