Front windshield films are always applied on the inside. If applied on the outside, exposure to wind and rain would reduce its lifespan by at least two-thirds. Moreover, if applied externally, glass fragments from impact could still injure people, failing to serve the purpose of explosion-proof film. Car window tinting refers to applying a thin film material (also called solar film or heat insulation film) on the front/rear windshields, side windows, and sunroof. The primary functions of car window films include: blocking UV rays, reducing heat transmission, preventing injuries from glass shattering, reducing glare, and protecting personal privacy through the one-way visibility feature of solar films.

How to Check for Car Air Conditioning Leaks?

Methods to check for car air conditioning leaks include: 1. Visually inspect the air conditioning system for oil stains, as these indicate leakage points; 2. Fill the system with nitrogen and apply soapy water to various parts—bubbles will form at leakage points; 3. Light a leak detection lamp and hold the air tube of the halogen lamp near the system—if the flame turns purple-blue, it indicates a leak; 4. Utilize the pressure difference between the inside and outside of the system, amplify the difference via a sensor, and display the leak detection results digitally, through sound, or via electronic signals; 5. Add fluorescent dye to the system in a specific ratio, wear specialized glasses, and illuminate the system externally with a detection lamp—leakage points will show yellow-green fluorescence.

What are the reasons for high carbon monoxide in the engine?

The reasons for high carbon monoxide in the engine are as follows: Sensor failure: The sensor that controls and stabilizes the air-fuel ratio fails, causing excessive gasoline injection. As a result, there is insufficient air for the car, leading to incomplete combustion and insufficient gasoline combustion, which increases the carbon monoxide in the exhaust. Clogged or dirty three-way catalytic converter: This can cause the three-way catalytic converter to lose its ability to convert carbon monoxide, requiring cleaning or replacement of the three-way catalytic converter. Excessive carbon deposits: Simply cleaning the carbon deposits to allow the fuel to burn completely and prevent the engine from accumulating carbon deposits will significantly reduce the carbon monoxide in the car's exhaust.
