In winter, the normal temperature for car air conditioning is between 18°C and 25°C. It is recommended to maintain a temperature difference of less than 10°C between the inside and outside of the car. The comfortable temperature range for the human body is 20°C to 25°C. If the temperature is too high, the large temperature difference between the inside and outside of the car can easily cause colds, while a temperature that is too low will affect driving comfort. When starting the car in winter, owners usually switch the air conditioning to heating mode. However, since the temperature of the radiator is very low when the engine starts in winter, it is not advisable to set the air conditioning temperature too high. Setting the temperature too high when the radiator is cold will increase the burden on the engine. The correct method is to wait for the engine to warm up, then turn on the heating mode, set the air circulation to external circulation to expel the cold air inside the car, and then adjust the air circulation to internal circulation.

How to Tell if the Front of the Car Has Fully Entered During Reverse Parking?

If the car body is already tilted and the rear of the car is leaning to one side, it means the steering wheel was straightened too early or the steering was turned too quickly. Observe whether the middle position of the parking space aligns with the middle position of the garage's baseline, allowing a lateral deviation within 10 centimeters. If the steering wheel is straightened too late, the middle position of the vehicle's rear end and the middle position of the garage's baseline will not align when the steering wheel is not fully straightened.

How to adjust the ignition timing of Weichai engine?

Weichai ignition timing adjustment method is as follows: 1. First align the scale line, generally align to 10 degrees. 2. Determine whether the exhaust rocker arms of cylinder 1 and cylinder 2 are fully depressed. 3. Align the fuel pump scale (the scale line of the fuel pump indicates fuel injection for cylinder 1). Relevant information about ignition timing is as follows: 1. Ignition timing refers to the angle between when the piston reaches top dead center and when ignition begins. Professionally, it is called ignition advance angle. 2. If ignition occurs too early, detonation will occur; if too late, knocking will occur, the engine will overheat, and mechanical efficiency will decrease. Therefore, there should be an optimal ignition advance angle, which means adjusting the ignition timing.

What to Do When Water Gets Inside the Headlight?

For relatively minor cases of water inside the headlight, there is no need to worry too much. After the headlight is turned on for a while, the moisture will evaporate and exit through the vent pipe. Disassemble it, open the headlight cover, and after drying, check the surface of the headlight for any damage or potential leakage points. When water gets inside the headlight, never attempt to bake the headlight to dry it, as this can easily damage the headlight since its exterior is made of plastic.
