Do vehicles need annual inspection every year?

The requirement for annual vehicle inspection depends on the vehicle type, with different inspection intervals for different vehicle models. According to regulations: 1. Passenger transport vehicles must be inspected once a year within the first 5 years, and every 6 months after exceeding 5 years; 2. Motorcycles must be inspected once every 2 years within the first 4 years, and once a year after exceeding 4 years; 3. Trucks and large/medium-sized non-commercial passenger vehicles must be inspected once a year within the first 10 years, and every 6 months after exceeding 10 years; 4. Small and mini non-commercial passenger vehicles must be inspected once every 2 years within the first 6 years, once a year after exceeding 6 years, and every 6 months after exceeding 15 years.

What is the Principle of Car Drifting?

Car drifting occurs when the rear wheels lose traction while the front wheels maintain grip. Here is relevant information: 1. Common drifting techniques: Handbrake turn: Using the handbrake to lock the rear wheels, causing them to lose traction and move in a circular motion. Since the vehicle brakes suddenly, the body swings dramatically, making this type of drift visually impressive. The handbrake is used when sharp turns are needed. The specific procedure is: Before turning, reduce speed, then apply the handbrake upon entering the curve, adjusting its intensity and duration based on road conditions and speed. Using the handbrake while driving may cause damage. 2. Clutch kick: During entry into a curve, quickly press and release the clutch, creating a sensation of 'kicking' it open, causing the drive wheels to momentarily lose traction, which, combined with steering and braking, induces a slide.

What are the consequences of a faulty oxygen sensor?

Once the oxygen sensor fails, the computer of the electronic fuel injection system will not be able to obtain information about the oxygen concentration in the exhaust pipe, thus unable to perform feedback control on the air-fuel ratio. This will lead to increased engine fuel consumption and exhaust pollution, as well as engine issues such as unstable idling, misfires, and surging. More information about the oxygen sensor is as follows: 1. The location and function of the oxygen sensor: The front oxygen sensor is located at the exhaust manifold and is used to adjust the mixture concentration. The rear oxygen sensor is located behind the three-way catalytic converter and is used to monitor the working condition of the three-way catalytic converter. 2. Replacement cycle of the oxygen sensor: There is no fixed replacement cycle for the oxygen sensor, but it is recommended to replace the oxygen sensor for vehicles with over 100,000 kilometers.

Do I Need to Replace the Lock If I Lost My Car Key?

No replacement is needed. After reprogramming a new key, the previous remote key will become invalid. Here are the specific functions of car keys: 1. Close windows after turning off the engine: Press and hold the lock button on the remote key to close the windows. This feature may also be available on ordinary family cars. 2. Locate the car in a parking lot: Some car keys have a dedicated car-finding button. For certain vehicles, pressing the lock button twice will trigger a very loud horn sound to indicate its location, making it easier to find the car quickly in crowded parking areas. 3. Automatic trunk opening: Many car models have a trunk-opening button on the remote key. Press and hold the trunk unlock button to automatically open the trunk. 4. Keyless entry: You need to carry the car key. When the key is near the car, it will automatically match with the car's decoder. Press the unlock button on the car door handle to unlock the car.

Is a tire pressure of 210 normal?

Tire pressure of 210 is not normal, indicating significantly low pressure. It is recommended to first use a tire pressure gauge to check if the actual pressure is normal. If the pressure is normal, then the issue may lie with the tire pressure sensor. Generally, the tire pressure for small cars is around 220, while for SUVs it is around 230. Only under normal tire pressure can the vehicle ensure it does not deviate during driving, and each tire's suspension can maintain the same wear state. There are two types of tire pressure monitoring: direct and indirect. Direct tire pressure monitoring uses pressure sensors installed in each tire to directly measure the tire's air pressure. Indirect tire pressure monitoring relies on calculating the tire's rolling radius to monitor pressure when a tire's pressure decreases.

What Do Those Numbers on Car Tires Mean?

Those numbers on car tires represent the following: Taking 215/65R15 as an example: 215 is the section width of the tire, which is the width between the two sidewalls; 65 is the aspect ratio, which is the ratio of the tire's height to its width, indicating here that the height is 65% of the width—the smaller the number, the flatter the tire appears; R stands for the tire's construction, indicating that this tire has a radial structure, meaning its cord plies are arranged radially inside the tire body; 15 is the rim diameter, meaning this tire must be matched with a 15-inch rim. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims to cushion external shocks, ensure contact with the road surface, and maintain the vehicle's driving performance.
