Why is the car engine emitting white smoke?

Reasons and solutions for a car engine emitting white smoke are as follows: 1. Low temperature: During engine operation, the exhaust gases encounter the low external temperature and condense instantly, producing water vapor that forms a large amount of mist-like white smoke. In this case, after the engine runs for a while, its temperature will rise, allowing the gasoline to burn fully, and the white smoke phenomenon will disappear. 2. Engine malfunction: If white smoke persists, it is usually caused by the engine burning oil. In this situation, it is generally necessary to visit a 4S shop for repairs.

How to Maintain Leather Seats?

Methods for maintaining leather seats: 1. Apply a protective agent, which not only reduces the penetration of moisture and dirt into the leather but also replenishes the leather with oil nutrients, effectively restoring its softness and breathability while extending its lifespan. 2. Pay attention to keeping the interior clean and hygienic. During daily use, it is important to develop good hygiene habits and avoid placing dirty clothes, towels, or basketballs on the leather seats. 3. Avoid installing seat covers. Car leather seats are not as delicate as one might think. With proper care, leather seats are actually more resistant to dirt than regular fabric seats. Ordinary dust and stains can be easily wiped away with a clean cloth, making maintenance very convenient. 4. Keep away from heat sources. If leather seats are exposed to high temperatures for extended periods, the leather can become dry, and in severe cases, the protective oil film can be damaged, accelerating the aging of the leather and leading to cracking and fading. It is advisable to apply a layer of heat-insulating film to your car and avoid parking it directly under the sun. If long-term parking in an open area is necessary, placing a sunshade in the car can help reduce UV damage to the leather seats.

What should be checked for a driver's license test?

The physical examination items required for a driver's license test include vision, hearing, height, color discrimination, and the motor ability of limbs, trunk, and neck. The examination fee is generally 50. Below is an introduction to the driving school physical examination items: 1. Height: Applicants for large buses, tractors, city buses, large trucks, and trolleybuses must have a height of 155 cm or above. Applicants for medium-sized buses must have a height of 150 cm or above. 2. Vision: Applicants for large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart for both eyes. Applicants for other vehicle types must have uncorrected or corrected visual acuity of at least 4.9 on the logarithmic visual acuity chart for both eyes. 3. Color discrimination: No red-green color blindness. This is consistent with the vision requirements in the driving school physical examination. 4. Hearing: Able to distinguish the direction of sound with each ear 50 cm away from a tuning fork. 5. Upper limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact, with normal limb and finger motor function. 6. Lower limbs: Normal motor function. Applicants for driving manual transmission vehicles must have a lower limb length difference of no more than 5 cm. Applicants for driving automatic transmission vehicles must have a sound right lower limb. 7. Trunk and neck: No motor dysfunction.

What Do the Letters on an Automatic Transmission Mean?

Generally, there are five letters on the gear shift of an automatic transmission car, arranged from top to bottom as: P, R, N, D, L. Here’s a detailed introduction: 1. P (Parking Gear): When the car is parked and not in use, the gear is set to this position. At this time, the wheels are mechanically locked to prevent rolling. 2. R (Reverse Gear): Used when reversing the car. 3. N (Neutral Gear): Used when temporarily stopping (e.g., at a red light). Note that this gear indicates neutral, and to prevent the car from rolling on a slope, the brake must be pressed. 4. D (Drive Gear): Also known as the driving gear, used when moving forward. 5. L (Low Gear): When going downhill or on a long slope, shifting to this gear limits the car's gear to the lowest gear only (equivalent to first gear in a manual transmission car). This allows the car to use engine power for braking when going downhill, preventing the driver from having to press the brake for a long time, which could overheat the brake pads and cause danger.

What to Do If You Accidentally Fill Your Car with 92 Instead of 95 Octane Gasoline?

It's not a big deal if you accidentally fill your car with 92 octane gasoline once or twice, but you should avoid mixing different octane levels for a long time. Here is some extended information about gasoline: 1. Cars have specified gasoline octane ratings, so it is not recommended to mix 95 and 92 octane gasoline. 2. The mixtures of 92 and 95 octane gasoline are essentially the same, but the difference lies in the proportion of their mixtures. Long-term mixing of different octane gasoline can reduce anti-knock properties, causing the engine to self-ignite before the designated ignition timing. This may lead to ignition system confusion, engine shaking, and in severe cases, damage to the car engine.

Where to Add Engine Oil?

Car engine oil filler port is generally located on the left side of the engine. If you need to add engine oil, here are the basic steps for adding engine oil: 1. After the car is parked and turned off for about ten minutes, pull out the oil dipstick and wipe the oil marks on the dipstick clean with a cloth. 2. Reinsert the oil dipstick into the dipstick tube, then pull it out again to check the oil marks on the dipstick; under normal circumstances, the oil marks should be between the upper and lower marks on the dipstick, slightly above the middle line. 3. If the oil marks are below the lower mark, it means the oil level is insufficient and you should add oil immediately. While adding oil, continuously pull out the oil dipstick to monitor the oil level.
