Should You Turn Off the Engine While Waiting in the Car?

If the waiting time is less than five minutes, you can keep the engine running; however, if it exceeds five minutes, it is advisable to turn off the engine. Otherwise, apart from wasting fuel and increasing engine carbon deposits, sitting in the car for an extended period while waiting not only consumes more fuel but also poses safety hazards. This is because the carbon monoxide content in car exhaust is extremely high. Prolonged idling while waiting can easily lead to carbon monoxide poisoning if not careful, especially in underground parking lots where it is crucial to avoid idling for too long. The hazards of prolonged idling are as follows: 1. Due to extended idling, the engine temperature remains too low, leading to incomplete fuel combustion, which can cause carbon buildup, clog the fuel injectors, and severe carbon deposits may even cause the piston rings to seize or break. 2. During prolonged idling, poor fuel atomization can result in unburned atomized diesel condensing and washing down the cylinder walls, entering the lubricating oil and diluting it, thereby accelerating engine wear as the moving parts do not receive adequate lubrication. 3. Poor combustion during prolonged idling worsens engine emissions. If toxic gases enter the cabin, occupants may face the risk of suffocation. Additionally, the release of toxic gases pollutes the environment. Some countries have traffic regulations that prohibit prolonged idling (limited to 3-5 minutes) when parking on the roadside, with fines enforced by traffic police for violations. 4. Low idle speed reduces the oil pump speed, leading to low oil pressure and insufficient lubrication at critical points. 5. While the engine maintains a constant internal operating temperature, components like the exhaust manifold and catalytic converter rely on airflow for cooling. Prolonged idling can hinder heat dissipation in high-temperature engine parts and may even damage the catalytic converter due to excessive heat. Generally, it is best not to let the engine idle for more than 10 minutes.

How to Properly Apply Car Window Tinting Film?

To properly apply car window tinting film, the following points should be noted: 1. After applying the film to the windshield, try to park facing the sun during the day. 2. Avoid rolling down the windows for three days after applying the film. 3. Do not wash the car for three days to prevent water from seeping in through the edges of the windows, which can cause excessive moisture at the edges of the glass and film, leading to peeling. 4. For vehicles with sunroofs, avoid opening the sunroof while driving, especially at high speeds, within three days to prevent air convection inside and outside the car, which may cause the upper edge of the windshield film to peel. 5. If bubbles appear at the edges of the tinting film, have them repaired at the installation site within 24 hours to prevent the adhesive from drying out and causing the film to become immobile, which may result in creases during handling. 6. Avoid using strong adhesive labels on the film for one month after application to prevent partial detachment. 7. In winter, try not to roll down the windows or wash the car for one week after applying the film.

When to Use High Beam While Driving?

During driving, high beams should only be used when there are no other lighting facilities on the road and no oncoming vehicles. Below are the precautions for using low beam and high beam in cars: 1. Low beam must be turned on in the following situations: when driving in areas without streetlights at night, or during dusk when it is relatively dark or at dawn when light first appears; if encountering heavy fog, snow, or heavy rain that obstructs visibility, low beam must be turned on even during the day; on some roads where there are lighting facilities but the brightness is insufficient, low beam should also be turned on. 2. High beam should only be used when there are no other lighting facilities on the road and no oncoming vehicles. Otherwise, it will seriously interfere with the vision of other drivers and may even cause traffic accidents. Be careful not to mistakenly use high beam instead of low beam. 3. High beam must be immediately switched to low beam in the following situations: first, when there is an oncoming vehicle; second, when the distance to the vehicle ahead in the same direction is relatively close; third, when the road already has sufficient lighting, as well as when crossing railway intersections or returning to busy streets.

What to Do When Car Windows Freeze in Snowy Weather?

Here are the solutions for dealing with frozen car windows in snowy weather: 1. Use lukewarm water to remove ice. When the ice on the windshield is not too thick, soak a cloth in lukewarm water (40-50°C), gently wipe the windshield several times, and then rinse with water at around 40°C. This usually clears the ice effectively. Avoid using hot water to melt the ice, as although it works faster, the drastic temperature difference can easily cause the windshield to crack. 2. Use warm air to defrost. Start the car and, once the engine warms up, direct the warm air toward the windshield until the ice melts. However, this method has drawbacks, such as being time-consuming, labor-intensive, and fuel-consuming. 3. Physical ice removal. Use a specialized ice scraper for car windows, which is more convenient, quick, and keeps your hands from freezing. When there is snow or ice on the glass, use a plastic scraper or a dedicated ice scraper to remove it.

When Can You Get Your Driver's License After Passing Subject 4?

After passing Subject 4, you can receive your license on-site, usually within about 2 hours. Subject 4, also known as the Subject 4 Theory Test or Driver's Theory Test, is part of the motor vehicle driver's license examination. The main content includes: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. The Subject 4 test consists of 50 questions, presented in the form of case studies, images, animations, etc. The maximum score is 100, with a passing score of 90. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: the road test and the addition of a safety and common sense test, commonly known as "Subject 4," which assesses "driving ethics." Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. Officially, there is no Subject 4. Before the test, students can study traffic regulations through driver's license simulation test software on mobile devices or computers.

How to Remove Water Stains from Car Windows?

Methods to remove water stains from glass are as follows: 1. Water stains on car windows can be removed with alcohol. Take a dry and a wet cloth, first wipe both sides of the glass with the wet cloth, then dip the dry cloth in a small amount of alcohol or high-proof liquor and scrub the glass vigorously to effectively remove water stains. 2. Water stains on car windows can be removed with clay bar. Wet the glass and rub the area with water stains back and forth with the clay bar. 3. Water stains on car windows can be removed with dishwashing liquid. Apply dishwashing liquid to a towel and then wipe the glass, which can also remove water stains with good results. However, it is important to rinse thoroughly after wiping to avoid residue that may cause wiper slippage. 4. Water stains on car windows can be removed with vinegar or soda water. Spray vinegar or soda water on the water stains, wipe with a towel, and finally rinse with clean water. 5. Water stains on car windows can be removed with professional car water stain remover. Pour the remover on a towel or sponge, wipe the stained area, then rinse with clean water, and dry with a soft, clean towel.
