Idling a car with the air conditioning on for one hour consumes approximately 2 liters of fuel. Here is some relevant information: 1. Precautions: Engine idling also consumes a significant amount of fuel. If the idling operation is only to power the air conditioning compressor, more energy is wasted. The engine remaining in a high-temperature state for a long time may lead to the accumulation of carbon dioxide and carbon monoxide inside the car, which is very dangerous. 2. Introduction to car idling vibration: There are many reasons for car vibration during cold starts and warm starts. Apart from incomplete fuel combustion, it could also be due to abnormal engine water temperature, low cylinder pressure, clogged fuel injectors, etc. If the car experiences startup vibration, it is recommended that the owner promptly take it to a 4S shop for inspection and repair.

Why is the electric car motor not turning and hard to push?

There are several reasons why an electric car motor may not turn and be difficult to push: Controller damage: The controller (three-phase AC inverter) may suddenly break down due to overheating, causing a short circuit between the output three-phase power supply components (at least between two phases). When pushing the vehicle, the motor operates in a short-circuit power generation state (working in energy-consuming braking mode), making it very difficult to push. Solution: Disconnect the controller's wiring to the motor to free the motor from the controller's short circuit, allowing the motor to operate in a no-load power generation state when pushed, making pushing easier. Internal motor short circuit: This may be caused by a sudden inter-turn short circuit inside the motor. In this case, even cutting the wiring at the motor terminals won't help, and pushing resistance will remain very high. The only solution is to tow the vehicle to a repair shop for motor servicing. (This situation is relatively rare)

Will the Car Display Show Night Mode During the Day?

During the day, the car display will not show night mode; it automatically switches to night mode only in the evening. Below is an introduction to night mode: Definition of Night Mode: The car night vision system uses infrared technology to make darkness appear as bright as daylight, allowing drivers to see farther and more clearly at night. The night vision system consists of two parts: an infrared camera and a light display system on the windshield. Benefits of Night Mode: With this night vision device installed, drivers can see road conditions as clearly as during the day through the light display system. When two vehicles meet, it significantly reduces the adverse visual stimulation caused by the strong headlights of the oncoming car and enhances the driver's ability to discern road conditions in foggy conditions.

Does changing a white car to laser white require registration?

Changing from pearl white to laser white does not require registration. Because the color difference between pearl white and laser white is not particularly significant, there is no need to go to the vehicle management office for registration. The exterior color of the car indicated on the vehicle license is only a rough designation and does not involve color changes. Similar color ranges: For example, there are many types of red, such as bright red, wine red, French red, etc., which are only labeled as red on the vehicle license. Similarly, white also comes in many varieties, such as taffeta white, pearl white, moon white, beige white, etc., but they are only labeled as white on the vehicle license. Registration is optional: Of course, if the owner is still concerned, they can go ahead and register without any issue. However, if the vehicle's color is changed from another color to white, such as from dark gray to red or from silver gray to sea blue, the color change is too significant, and registration is mandatory. This is no longer just a color change but a shift to a different color category, which requires registration. Otherwise, the vehicle will not pass the annual inspection.

Do pickup trucks need to go through weighbridges on highways?

Pickup trucks do not need to go through weighbridges on highways. Legal regulations: According to the relevant regulations in January 2020, all trucks must pass through weigh-in-motion channels. Therefore, blue-plate trucks with ETC must go through weigh-in-motion channels when entering the highway. However, this weigh-in-motion channel refers to the entry point. Blue-plate trucks only need to be weighed when entering the highway and can freely choose the exit channel when leaving. Blue-plate truck ETC lanes: When entering the highway, blue-plate trucks need to pass through weigh-in-motion channels. When exiting the highway, they can choose the ETC lane if they have ETC; otherwise, they should use the truck lane.
