What are the classifications of transmissions?

Transmission classifications: manual transmission, automatic transmission, automated manual transmission, continuously variable transmission. Detailed introductions are as follows: Manual transmission: When shifting gears with a manual transmission, you need to depress the clutch, then move the gear lever, and finally release the clutch to complete the gear shift. Automatic transmission: A good automatic transmission shifts responsively with reasonable logic, achieving excellent fuel consumption results. Compared to manual transmissions, automatic transmissions are more convenient to operate, generally requiring no gear changes while driving. However, there is some loss in transmission efficiency, resulting in higher fuel consumption than manual transmissions. Automated manual transmission: An automated manual transmission is essentially a manual transmission with an added control computer, typically with 5 speeds and lacking D and P gears. Continuously variable transmission: A continuously variable transmission can achieve continuous changes in the transmission ratio, thereby achieving the best match between the transmission system and the engine's operating conditions. Its advantages include smooth operation, no jerking sensation, and strong driving comfort. The disadvantages are a relatively poor ability to withstand torque and slower response to speed changes.

I've been driving for twenty years, and there's a lot to know about transmissions. The manual transmission (MT) is the oldest, offering high driving pleasure but can leave your legs numb from clutching in city traffic. The automatic transmission (AT) uses a torque converter for shifting, and with mature technology nowadays, it rarely lags like in the early days. The automated manual transmission (AMT) is like adding a robot to a manual to shift for you, perfect for those who want to be lazy but still crave some control. The continuously variable transmission (CVT) works like a rubber band with no fixed gears, providing smooth starts but can make the engine roar during sudden acceleration. The dual-clutch transmission (DCT) comes in dry and wet types, shifting lightning-fast and saving fuel, though some cars may jerk annoyingly at low speeds. Choosing a transmission is like picking shoes: AT is like sneakers—versatile, CVT like flats—comfortable, DCT like running shoes—energetic, depending on your daily road conditions.

Currently, mainstream transmissions are basically divided into five major categories. Manual Transmission (MT) is the most primitive three-pedal structure, essential for obtaining a driver's license but increasingly rare. Traditional Automatic Transmission (AT) is the most hassle-free—just shift to D and you're good to go, especially suitable for novice drivers. Continuously Variable Transmission (CVT) is now widely used in many Japanese cars, delivering power as smooth as butter, but don't expect it for racing. Dual-Clutch Transmission (DCT) comes in dry and wet variants, with Porsche's PDK being the top-tier wet version, offering lightning-fast gear shifts. Automated Manual Transmission (AMT) is considered a semi-automatic and is commonly found in entry-level models. Choosing a transmission depends on usage scenarios: DCT is the most exhilarating for frequent highway driving, while AT or CVT is the most comfortable for daily city commutes. Maintenance costs vary significantly—repairing a DCT can cost half the price of a new transmission.

How to Repair a Dented Car Door Sill?

Car door sill dent repair method is: The car's rocker panel is relatively hard, so it is necessary to go to a 4S shop and have maintenance personnel use professional repair tools for the repair. The sill is located below the four car doors. After the dent is repaired, protective measures must be taken, and regular maintenance should be performed to avoid collisions that may cause deformation. The car door provides access for the driver and passengers and isolates external interference, to some extent reducing side impacts and protecting the occupants. The shape of the door is related to the aesthetics of the car, and the quality of the door is mainly reflected in its anti-collision performance, sealing performance, ease of opening and closing, and functional indicators.

Does stopping on the crosswalk count as running a red light?

No. If the vehicle stops on the crosswalk during a red light and remains stationary, it will not be considered running a red light. However, if the vehicle continues to proceed in violation of the rules, it constitutes running a red light, resulting in a 6-point penalty. If the vehicle crosses the stop line completely and continues moving until fully past the line, thereby affecting the passage of other vehicles or pedestrians, it will be penalized as stopping beyond the line. Crossing the stop line can be divided into two scenarios: the front wheels crossing the stop line, or the entire vehicle crossing the stop line. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states the following for motor vehicle and non-motor vehicle signal lights: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. At intersections without non-motor vehicle or pedestrian crossing signal lights, non-motor vehicles and pedestrians should follow the motor vehicle signal lights. The new traffic regulations clearly specify three necessary conditions for a vehicle to be considered running a red light: The vehicle illegally crosses the stop line. The vehicle illegally enters the intersection. The vehicle illegally crosses the opposite stop line. Electronic police (traffic cameras) capture three complete video images to determine a vehicle running a red light: an image of the violation, an image of the license plate, and a panoramic image. There are three scenarios for determining whether a vehicle running a red light is in violation: If the vehicle stops immediately after its front wheels cross the stop line or if both front and rear wheels cross but the rear does not fully pass the stop line, traffic police will not penalize it as running a red light but may penalize it for improper stopping, deducting 2 points. If the vehicle stops after its front wheels cross the stop line and then reverses, and electronic cameras capture two complete movements, it will be treated as running a red light, resulting in a 6-point penalty and a fine. If the entire vehicle fully crosses the stop line and stops or continues moving, and electronic cameras capture the three complete images constituting a red-light violation within one red-light cycle, regardless of whether the vehicle reaches the intersection or crosses the opposite stop line, it will be penalized as running a red light, resulting in a 6-point penalty and a fine. The new traffic regulations stipulate that violating traffic signal lights while driving will result in a 6-point penalty. However, not all violations will lead to a 6-point deduction. For instance, violations such as making a left turn from a straight-only lane will still be penalized under the "Road Traffic Safety Law" with a 3-point deduction for violating prohibition signs. Additionally, red-light violations recorded by cameras will only incur a fine without point deductions.

Is it dangerous if the cigarette lighter doesn't pop out?

The cigarette lighter not popping out can be dangerous. If it's not due to a blown fuse, it may be caused by a loose or damaged retaining spring preventing the lighter from popping out. In this case, the lighter can still heat up normally, but remaining in a continuous heating state may cause the lighter's fuse to blow. The wiring of the lighter may overheat, leading to scorching and short circuits. The cigarette lighter is a component in cars designed to provide a flame source for smokers. It serves as a device for lighting cigarettes and can also be equipped with a car power inverter to convert the vehicle's 12V, 24V, or 48V DC power into current usable by common electrical appliances.
