Here is an introduction to the gears of an automatic transmission car: The gears of an automatic transmission car are divided into P, R, N, D, 2 (or S), L (or 1), etc. 1. P (Parking) Parking gear, starting gear: When you park the car and do not use it, the gear is in this position, and the wheels are mechanically locked to prevent rolling. 2. R (Reverse) Reverse gear: Used when reversing. 3. N (Neutral) Neutral gear: This gear indicates neutral. To prevent the vehicle from rolling on a slope, you must step on the brake. 4. D (Drive) Forward gear, also known as the driving gear: In D gear, the transmission will automatically switch between 1st gear and overdrive gear (equivalent to 1st to 4th gear) based on speed and throttle conditions. This gear is used for general road driving. 5. L (Low) Low gear: When going downhill or on long-distance slopes, shifting into this gear limits the car's gear to only the lowest gear (equivalent to the 1st gear of a manual transmission car). 6. S (Sport) Sport mode: When shifting into this gear, the gear can be freely switched. 7. 2 (Second-Gear): 2nd gear is a forward gear, but the transmission can only switch between 1st and 2nd gears and will not jump to 3rd or 4th gear. 8. 1 (First-Gear): 1st gear is also a forward gear, but the transmission can only operate in 1st gear and cannot switch to other gears. 9. OD: OD gear is the overdrive gear, used for high-speed driving to achieve fuel-saving purposes.

When I first bought a car and learned about automatic transmissions, the gear positions were quite simple: P stands for Parking gear, used when parking to prevent rolling; R is Reverse gear, used when backing up, so be careful to check behind you; N is Neutral gear, used for brief stops like at traffic lights, but avoid leaving it in this position for too long to prevent wear; D is Drive gear, used for normal driving as it automatically shifts up and down; L is Low gear, useful for steep descents or climbing to save fuel and protect the brakes; S is Sport gear, great for quick acceleration but consumes more fuel. For daily driving, 95% of the time you'll use D gear. Beginners shouldn’t panic—just press the brake when starting and shift to P gear, change gears slowly, and remember to maintain the transmission regularly.

What are the reasons for spark plugs turning black?

The most common reason for spark plugs turning black is poor combustion. The black substance is caused by carbon deposits and burning engine oil. Working principle of spark plugs: Under high voltage, the air between the center electrode and side electrode of a spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel between the gap, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark." Accompanied by thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2000-3000°C, sufficient to ignite the air-fuel mixture in the engine cylinder. Spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the user manual. The following standards can be referenced for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000-80,000 kilometers.

What Should You Pay Attention to for Vehicles in Winter?

Winter driving precautions require drivers to pay high attention to driving safety under special winter weather conditions and enhance their awareness of safe driving. When operating vehicles, drive smoothly and decelerate skillfully. High Importance on Driving Safety: Drivers must pay high attention to driving safety under special winter weather conditions and enhance their awareness of safe driving. When operating vehicles, stay focused, control speed, and drive in a standardized manner. Anticipate and handle emergencies such as skidding, side slipping, deviation, pedestrians, and non-motorized vehicles crossing the road during starting, stopping, turning around, turning, changing lanes, and meeting other vehicles. Practice starting on slopes is strictly prohibited in snowy and icy weather. Smooth Driving: After winter snow, roads are slippery. Pay attention to maintaining a steady speed and uniform operations while driving. Actions such as sudden acceleration, hard braking, and sharp turns are major taboos for driving on snow. Accelerate smoothly and drive at medium to low speeds. Skillful Deceleration: When decelerating, make full use of the engine's resistance to slow down. Quickly release the throttle without disengaging the gear or depressing the clutch, causing the engine speed to drop immediately and forcing the drive wheels to slow down, thereby decelerating the vehicle. If braking is necessary to stop, first reduce the speed using engine braking, then lightly apply the brakes. Emergency braking is absolutely prohibited on icy and snowy roads to prevent vehicle skidding.

Why is the car remote not working even though it has power?

Car remote has power but is not functioning properly. The reasons and solutions are as follows: Internal moisture: After prolonged use of the car key, due to sealing issues, internal moisture or dirt oxidation can make the buttons less responsive. In this case, you need to disassemble the key shell and use a cotton swab dipped in alcohol to clean the button base on the internal circuit board of the key. After cleaning, reassemble and test if it works normally. Car battery dead: The second reason could be that the car battery is dead, causing the vehicle to not receive signals, resulting in the car key malfunctioning. In this situation, you can use the mechanical key inside the remote to open the car door, as every remote key comes with a mechanical key, allowing you to unlock the door manually.

Should You Use Internal or External Air Circulation When Running the Car AC in Summer?

Whether to use internal or external air circulation when running the car AC in summer depends on the situation: use internal circulation for short trips and external circulation for long trips. Internal and external circulation in cars refer to: Internal circulation: The AC system is closed to outside air and can only circulate the air inside the car cabin; External circulation: The AC system is open to outside air and draws in fresh air from outside the car for circulation. Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety.

Can an Inter-Wheel Differential Lock Turn?

An inter-wheel differential lock cannot turn. Below is an introduction to differential locks: Forced Locking Type: The forced locking differential lock is set on an ordinary symmetrical bevel gear differential. This type of differential lock has a simple structure, is easy to manufacture, and has a high torque distribution ratio. However, it is quite inconvenient to operate, generally requiring the vehicle to stop. Additionally, if the differential lock is engaged too early or disengaged too late, it can lead to a series of issues similar to those without a differential, with an unchangeable torque distribution. High-Friction Self-Locking Type: The high-friction self-locking type includes structures like the friction plate type and the sliding block cam type. The friction plate type locks the differential through the frictional torque generated when the friction plates slide relative to each other. This type of differential lock has a simple structure and operates smoothly, making it very common in cars and light vehicles. The sliding block cam type uses the large frictional torque between the sliding block and the cam to lock the differential, significantly improving the vehicle's off-road performance. However, it has a complex structure, high manufacturing requirements, significant wear on friction components, and higher costs. Torsen Type: The Torsen differential is a new type of inter-axle differential widely used in all-wheel-drive cars (such as the Audi TT). It employs the basic principle of worm gear transmission with self-locking characteristics. The Torsen differential has a compact structure, a wide and adjustable range of torque transmission, making it widely used as the central differential in all-wheel-drive cars and the inter-wheel differential in rear-drive axles. However, due to its automatic locking effect under high-speed torque differences, it generally cannot be used as an inter-wheel differential in front-drive axles.

How many points are deducted for making a U-turn at a red light?

Making a U-turn at a red light is an offense that results in a deduction of 6 points. Some drivers, seeing the long duration of the red light and needing to make a U-turn, decide to do so during the red light, which is very dangerous. Below is relevant information: Relevant regulations: Making a U-turn at a red light violates the Road Traffic Safety Law. According to the "Scoring Standards for Road Traffic Violations": driving a motor vehicle in violation of traffic signal lights results in a deduction of 6 points per offense. At signalized intersections: if there is a U-turn marking, it indicates that U-turns are permitted. If the central median has a gap before the stop line, you can make a U-turn directly without crossing the stop line. If there is no gap, you need to wait for the left-turn green light (unless there is a marking indicating that U-turns are allowed when the straight-ahead signal is red), otherwise, you may be caught by traffic cameras.
