Curb weight is measured using the following standard methods: Measurement using a weighbridge: Drive the vehicle slowly and steadily onto the weighbridge. After it comes to a complete stop, measure the curb weight/unladen weight. For trailers, first measure the curb weight of the vehicle combination and the curb weight of the tractor, then calculate the difference between the two to determine the trailer's curb weight. To measure the trailer's unladen weight, first measure the unladen weight of the vehicle combination, then subtract the driver's weight (calculated as 75kg) and the registered curb weight of the tractor. The resulting difference is the trailer's unladen weight. Measurement using an axle (wheel) load scale: When using an axle (wheel) load scale, drive the vehicle slowly and steadily onto the weighing plate axle by axle (treating tandem axles and tridem axles as single axles). After the vehicle comes to a complete stop, measure the axle load. The sum of all axle loads is recorded as the vehicle's curb weight/unladen weight. For measuring the curb weight/unladen weight of trailers, follow points 2 and 3 of the weighbridge measurement method described above.

What Causes Car Shaking When Turning on AC and Braking?

Here are the specific reasons for car shaking when turning on the AC and braking: 1. Suspension system failure: The suspension system is primarily responsible for filtering engine vibrations during operation. If the suspension malfunctions, these vibrations will be directly transmitted to the steering wheel and cabin, affecting driving. 2. Unstable oil pressure: If the engine carbon has been cleaned, the throttle valve has been washed, and the oil pad has been replaced, but the car still shakes, it is recommended to check the fuel supply pressure and the intake pressure sensor at a repair shop. Abnormal fuel pump supply pressure or incorrect intake pressure sensor values can cause the car to shake. 3. Cold start: The main reason for car shaking during a cold start is insufficient fuel combustion, leading to reduced car power. Low ignition energy means that during startup, when the temperature of fuel and lubricating oil is low, more fuel is needed to meet power demands. Over time, the spark plug gap gradually increases, leading to decreased ignition energy and poor fuel atomization, resulting in car shaking.

Can You Use Fuel from Private Mobile Fueling Vehicles?

Fuel from private gas stations can indeed be used, but it's important to choose a trustworthy station. Here are some precautions for refueling your car: 1. Refuel in time: The fuel pump generates heat while working. If the fuel level is too low, the pump cannot dissipate heat in time, accelerating its aging. Therefore, it's best to refuel when the remaining fuel is about one-quarter. 2. Fuel quality: When refueling, choose stations with better fuel quality. It is recommended to go to state-owned gas stations. 3. Octane rating: Pay attention to the octane rating when refueling. The recommended fuel grade for your car is usually indicated on the fuel tank cap. A car designed for 95 octane can run on 92 octane, but long-term use may affect the vehicle. 4. Fuel quantity: Avoid overfilling the tank to reduce trips to the gas station. Generally, filling until the first click of the nozzle is sufficient, as this usually means the fuel level is at about 80-90% full. This leaves enough space in the tank for the gas vapors produced by fuel evaporation.
