What causes pressure loss in the right rear tire?

Right rear tire pressure is abnormal and requires calibration. Here is relevant information: Tire Pressure: Tire pressure monitoring can include two types, direct and indirect. Direct systems are more expensive but provide more accurate monitoring results. Direct tire pressure monitoring uses sensors installed inside the tires to measure tire pressure, then transmits the information to the dashboard via a wireless transmitter. When the tire pressure is too low or too high, it automatically alerts and displays the pressure value. Direct tire pressure monitoring is more expensive but more precise. Tires: Car tires are one of the most important components of a vehicle, directly contacting the road surface and working with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness. They also maintain strong traction between the wheels and the road, improving the vehicle's traction, braking, and off-road capability. Additionally, they bear the weight of the car, making their role increasingly recognized as crucial.

Where Are the Side Airbags Located in a Car?

Car side airbags are safety airbags installed on the outer side of the car seats. Their function is to deploy when the vehicle is subjected to a side impact, protecting the passengers' sides and reducing injuries caused by the collision. Below is a detailed introduction to side airbags: 1. Side airbags are further divided into front side airbags and rear side airbags. Both front and rear side airbags are positioned on the side of the car seats near the windows. Typically, there are seven sensors in the car. When the sensors detect a side impact, the airbags will automatically deploy to protect the safety of the driver or front passenger. 2. The airbag system mainly consists of components such as sensors, a microprocessor, a gas generator, and the airbag itself. The sensors and microprocessor are used to assess the severity of the collision and transmit signals. The gas generator, upon receiving the signal, ignites solid fuel to produce gas that inflates the airbag, causing it to rapidly expand. The airbag capacity is approximately (50-90) liters.

Can a 48V be upgraded to 72V without changing the motor?

No, if the original battery of an electric vehicle is 48V, adding two more batteries to make it 72V will definitely require replacing the controller and the motor. Without changing the controller, it won't function, and if the motor isn't replaced, the coils will burn out. 1. If the "motor is not replaced" and remains at 48V, under 72V, the load current will surge due to overvoltage, and the excessive current will burn out the controller. At the same time, the 48V motor will also be damaged by the overvoltage. 2. The "rated operating voltage" of the motor is crucial and is a necessary condition for the safe operation of the motor. For example, the rated operating voltage of a household air conditioner is 220V, and arbitrarily increasing the voltage is clearly unwise.

What is the penalty for driving without license plates?

Driving without license plates incurs a fine of 200 RMB and 12 penalty points. Vehicles without plates will be impounded, while those carrying plates (though not installed) won't be confiscated. License plates are mandatory legal documents for road use. The Road Traffic Safety Law stipulates: "When driving motor vehicles on roads, license plates must be displayed along with inspection stickers, insurance marks, and vehicle registration certificates. Plates shall be clearly and completely mounted without intentional obstruction or damage." The Implementation Regulations further specify: "License plates must be mounted at designated front/rear positions with clear visibility." Partial regulations regarding unlicensed driving: 1. No documentation: Vehicles without plates/proper documentation will be impounded with 200 RMB fine and 12 points deducted. 2. Complete documentation: If carrying plates with all documents, typically only monetary penalties apply (200 RMB fine + 12 points) without vehicle impoundment.

What does an active grille shutter mean?

An active grille shutter refers to an intake grille that can actively open or close, a feature equipped on many vehicles. The active grille shutter can reduce air resistance and accelerate engine warm-up. The ability to adjust the opening and closing of the grille means controlling intake and heat dissipation. Advantages of active grille shutters: 1. Shorter warm-up time. A vehicle can only reach its optimal state after the coolant reaches the appropriate temperature. The advantage of the active grille shutter becomes evident here. After starting the vehicle, the active grille shutter automatically adjusts its opening based on the engine temperature, achieving faster warm-up. 2. Lower drag coefficient. As the "window" of the engine compartment, the active grille shutter can also reduce the vehicle's drag coefficient when closed at the right time (for example, in the ATS-L, when the speed exceeds 60km/h, the onboard computer monitors the engine temperature and activates the active grille shutter when no additional air cooling is needed). This enhances vehicle stability and fuel economy.

How to Replace a Lost Driver's License and How Long Does It Take?

If a driver's license is lost and the driver has not accumulated 12 penalty points, has undergone timely inspections, and the license has not been revoked, suspended, or canceled, the driver can bring relevant documents (such as identity proof and a written statement of the lost driver's license) to the vehicle management office for replacement. The traffic management department of the public security authority will verify the information with the driver's license records and issue a replacement within 3 days of receiving the application. Here is some information about driver's licenses: 1. Definition: A driver's license (full name: Motor Vehicle Driver's License), also known as a 'driving license,' is a document issued by the government's transportation department to individuals qualified to drive. 2. Requirements for obtaining: To obtain a driver's license, one must meet the minimum age requirement and pass the driving qualification exam.
