How to Prevent Car from Sun Exposure

Car sunshades can effectively protect the vehicle from the impact of sun exposure. For the front windshield, using a dedicated front windshield sunshade is sufficient. Try to park the car in a garage or in shaded areas such as under buildings or trees. Choosing a full-car heat-insulating window film can provide relatively good heat insulation. It is best to have the film installed at a reputable car beauty shop for better quality. Car covers also offer some sun protection and can prevent dust. Opt for thicker ones to extend their lifespan. Choose a cover that fits your car model.

How to Remove the Speed Limit on Xinlei 48V

Locate the power switch of the Xinlei 48V and check if the power is on. Do not turn on the power. Hold the brake lever and turn the throttle to the maximum. Turn on the power while holding the brake lever and rotate the throttle to the maximum three times consecutively. On the third time, keep the throttle turned to the maximum for 5 to 8 seconds. The speed limit wire of the electric vehicle is generally located on the controller under the seat. Next to the controller, there is a single white power wire, which is a standalone wire. Cut this white wire. With the power lock off, hold the brake lever and turn the throttle to the maximum. Turn on the power lock, keep the throttle and brake engaged for 3-5 seconds to enter full-speed mode.

How to Replace the Headlight Bulb of an Emgrand Car?

Open the front hood of the car, locate the headlight bulb, and take a photo to record the installation configuration of the bulb. Firmly pull out the power cord of the bulb with the blue coil; the blue circle indicates the bulb socket. Simply pull it out to expose the bulb base. You can see how the power cord is pulled out. Be sure to first remove the bulb socket before releasing the metal clip handle of the bulb. Press down in the direction of the blue arrow without letting go, then push to the right to loosen the headlight clip. Once loosened, directly pull out the bulb. Unbox the newly purchased bulb, install the new bulb, secure the bulb clip, and plug in the bulb power cord to complete the installation.

What is the working principle of the ABS system?

ABS system, also known as the Anti-lock Braking System, works as follows: During braking, the ABS system, based on speed signals from each wheel speed sensor, closes the normally open input solenoid valve for the wheel that is starting to lock up, maintaining the braking force. If the wheel continues to lock, the normally closed output solenoid valve is opened. This keeps the braking state at the optimal point, ensuring the best braking performance and the highest level of driving safety. ABS, short for Anti-lock Braking System, functions to automatically control the braking force during vehicle braking, preventing the wheels from locking up and keeping them in a state of rolling and sliding (with a slip ratio of about 20%). This ensures maximum traction between the wheels and the road surface. The ABS system mainly consists of four components: wheel speed sensors, the electronic control unit (ECU), the hydraulic unit, and the ABS warning light. The wheel speed sensors detect the motion state of the wheels and generate sinusoidal electronic pulse AC signals. These signals are then processed by a modulator, converted into digital signals, and transmitted to the electronic control unit. The electronic central control unit (ECU) receives input signals from the wheel speed sensors and uses these parameters to calculate the wheel speed, vehicle speed, and slip ratio. Based on the slip ratio, it determines the state of the wheels and issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure in the brake lines according to the control commands. The adjustment process includes maintaining pressure, increasing pressure, and decreasing pressure. The ABS warning light alerts the driver to any system faults. If the ABS warning light is illuminated, it is recommended not to continue driving. This is because the ABS light indicates a fault in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

How to Properly Warm Up an Automatic Transmission Car?

First, it is necessary to get the engine running. Run the engine for thirty seconds to 1 minute before driving. When starting off, drive at low speed for a while to allow the system to reach normal operating temperature before driving at high speed. After the engine temperature rises to the normal level (approximately 3 to 5 minutes), you can resume normal driving. The purpose of warming up the car is to bring the engine temperature to around 90 degrees, so that the relative temperature inside and outside the entire engine can approach the ideal state.
