Is It Necessary to Clean Carbon Deposits in Cars?

It is necessary to clean carbon deposits in cars because there is currently no complete method to prevent their formation. If not cleaned regularly, carbon deposits will accumulate endlessly, leading to minor issues such as engine shaking and reduced power, or more severe problems like engine cylinder scuffing, seizure, or even knocking. Engine carbon deposits are a coking-like substance formed from unsaturated olefins and gums in fuel under high temperatures. The engine is the device that provides power to the car, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems.

Where to Apply Car Window Film?

Car window film needs to be applied to the front and rear windshields, side windows, and sunroof of the vehicle. It is recommended to apply the film on the interior side of the car glass. Applying it on the interior side avoids exposure to wind and rain, minimizing external interference during use. If applied on the exterior side, the film may get damaged by windshield wipers or soaked by rainwater, causing bubbles. Car window film involves applying a thin layer of material, also known as solar film or heat-insulating film, to the front and rear windshields, side windows, and sunroof of the vehicle. After applying car window film, it is important to note: Do not wash the car for three days. Avoid rolling down the windows within three days to prevent displacement of the film. During this period, you can clean the film surface with a wet towel, sponge, or soft cloth. If the vehicle has a sunroof, avoid opening it for three days. The main functions of car window film include: Heat insulation and cooling. The film can reduce the intensity of sunlight, providing heat insulation and keeping the cabin cool. High-quality car window films can achieve an insulation rate of 50% to 70%, effectively reducing the load on the car's air conditioning system and saving fuel. Preventing shattering. In the event of an accident, shatterproof car window film can prevent glass from breaking and scattering, reducing the risk of injury from glass fragments to the driver and passengers, thereby enhancing vehicle safety. Skin protection. Prolonged exposure to ultraviolet (UV) rays can harm the skin and cause skin diseases. High-quality car window films have UV-blocking properties, effectively shielding against UV rays and protecting the skin. Interior protection. Infrared rays from sunlight can heat up interior components such as seat cushions and dashboards. Prolonged exposure to infrared rays can cause interior materials to age and fade. Window films can protect the interior from such damage. Color enhancement. Colorful window films can change the monotone appearance of car windows, adding aesthetic appeal to the vehicle. One-way visibility. One-way visibility films can block outside views, enhancing privacy for the vehicle's occupants. Anti-glare properties. High-quality anti-glare films can filter out certain glare and reduce the intensity of visible light, making it more comfortable for the eyes. This helps improve the driver's visibility and ensures safer driving. It is recommended to avoid films with too low light transmittance. For side windows, especially the front ones, films with a light transmittance of over 85% are more suitable. Such films do not require cutouts and do not obstruct vision. At night, they can also reduce the reflection of strong glare from headlights in the rearview mirror, making driving more comfortable. Additionally, they ensure good visibility during rainy nights, reversing, and turning.
