Choosing an AT transmission is better because AT transmissions offer excellent smoothness and durability. Below is relevant information about transmissions: Introduction to transmissions: A device that changes speed ratios and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machinery to alter the torque, speed, and direction of motion transmitted from the drive shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. Function of transmissions: While driving, to adapt to different working conditions, a vehicle's driving force and speed need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the installation of a transmission.

When it comes to which is better between DCT and AT, I think from the perspective of driving pleasure, the DCT dual-clutch transmission suits my taste more. It shifts gears as fast as lightning, especially thrilling during high-speed overtaking or cornering, and it's also quite fuel-efficient, particularly on long journeys. However, in urban traffic jams, it can occasionally jerk and become annoying, not as smooth as the AT. The AT automatic transmission, though a bit heavier, is simpler to operate, more reliable, and cheaper to maintain. Overall, I prefer the DCT for its strong sense of speed, making it suitable for speed enthusiasts like me. But choosing a car still depends on daily road conditions and budget, and don’t overlook maintenance costs.

As a driver who frequently takes family trips, I prefer AT automatic transmissions. They provide smooth and comfortable driving at low speeds, preventing the kids in the back from getting carsick due to bumps, and the operation is simple—just step on the accelerator. Although DCT dual-clutch transmissions shift quickly and save fuel, the jerky sensation during startup and acceleration is too noticeable, and their complex structure increases the likelihood of malfunctions. For long-term use, AT has lower maintenance costs, readily available parts, and can be serviced at any repair shop, unlike the more delicate DCT. In terms of safety and daily practicality, AT comes out on top, especially for short urban commutes, making it the more worry-free choice.

From a cost-saving perspective, I would compare the economic efficiency of DCT and AT. DCT usually has a higher purchase price but offers lower fuel consumption, saving money in the long run; AT is cheaper to buy but has higher fuel consumption. In terms of maintenance, AT has lower repair costs and better general reliability; DCT is prone to minor issues with higher repair expenses. For long-distance highway driving, DCT's fuel-saving advantage is significant; in urban traffic congestion, AT is more cost-effective. The choice depends on calculating the total cost based on driving habits and mileage.

How to Handle a Motorcycle Seized by Traffic Police for Not Being Licensed?

Unlicensed driving mainly falls into two scenarios. Below is a detailed explanation of the consequences and necessary actions for unlicensed driving: 1. With a driver's license: (1) 12 points will be deducted from the C1 driver's license, along with a fine and the temporary suspension of the C1 license. (2) Within 30 working days, you must attend a 7-working-day course at the traffic police team's learning center (with four daily check-ins, at least 4 hours per day). After completing the course, obtain the full-score review certificate, and then reapply for the C1 license's subject one exam. 2. Without a driver's license: (1) 7 days of detention and a fine. (2) After 7 days, go to the traffic police brigade where the vehicle was seized to handle the matter with the relevant personnel. Follow the procedures, and when retrieving the vehicle, a guarantor holding a C2 driver's license must accompany you. Additionally, you need to take the test and license the vehicle as soon as possible.

What are the three certificates for motorcycles?

Motorcycle three certificates are driver's license, vehicle license, and insurance label. Motorcycles, driven by gasoline engines and steered by handlebars to turn the front wheels, are two or three-wheeled vehicles that are lightweight, flexible, and fast. They are widely used for patrols, passenger and cargo transportation, and also serve as sports equipment. Broadly speaking, motorcycles are divided into street bikes and road racing bikes. Here are some additional notes on motorcycle road use: 1. Motorcycles need to have a vehicle license, and drivers must pass practice and obtain a driver's license before they can ride on the road. 2. Drivers must wear safety helmets to prevent accidents and reduce injuries. 3. Motorcycles must not be overloaded, whether carrying goods or passengers, to avoid losing control of the vehicle and causing accidents. 4. Traffic accidents are more dangerous than tigers, often caused by speeding, especially for motorcycles, which are prone to accidents when speeding. 5. Alcohol impairs judgment, so never ride a motorcycle after drinking, to avoid violating traffic rules and causing harm to yourself and others.

Why Do Vans Consume More Fuel?

There are multiple reasons why vans are particularly fuel-consuming. Here is a detailed explanation: 1. Vehicle-related reasons: (1) Excessive carbon deposits in the engine: The main reason for excessive carbon deposits in the engine in a short period is the use of unsuitable fuel. This situation is more likely to occur after long-distance driving or lending the vehicle to others. When driving long distances, it is inevitable to refuel at various locations. Even for the same grade of fuel, the quality may vary, leading to the accidental use of unsuitable fuel. Lending the vehicle to others makes it even harder to control the quality of the fuel added. (2) Long overdue replacement of the "three filters": During vehicle use, the three filters (oil filter, air filter, and fuel filter) must be replaced regularly. If not replaced for a long time, they become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits. (3) Damaged oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once damaged, it causes an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe emits darker-colored exhaust during driving. 2. External factors: (1) Bad driving habits: Personal driving habits have a significant impact on fuel consumption, such as sudden acceleration and hard braking, which affect the vehicle's fuel consumption. The optimal driving speed should be maintained at 60-80 km/h. Additionally, observing road conditions in advance and using the throttle to control speed can help. (2) Road conditions: Choosing the right route is also a crucial factor in fuel efficiency. Sometimes, a longer distance may not necessarily mean worse road conditions. Therefore, when selecting a route, try to choose less congested and shorter routes to save more fuel.

Can Motorcycles Be Purchased with a Loan?

Motorcycles can be purchased with a loan. Currently, loans are available for motorcycle purchases, though conditions may vary by location. Buyers typically need to provide identification documents, household registration, marriage certificate or single status proof, as well as work and company contact numbers. Below are two methods for obtaining a motorcycle loan: 1. Credit Card Installment Payment: (1) The buyer brings proof of income and ID to the bank to apply for a credit card. After receiving the card, they can pay in full at the motorcycle dealership and take the motorcycle home. (2) After payment with the credit card, the buyer calls the bank's service hotline to apply for installment repayment. They simply deposit money into the card each month for repayment, which is unrelated to the dealership and does not require a down payment. 2. Installment Payment at the Dealership: (1) The buyer's employer should provide proof to the dealership. (2) The dealership then obtains the motorcycle loan through the bank. (3) The buyer only needs to pay the bank's interest upfront, followed by installment payments as per the bank's terms. (4) The buyer will pay a certain percentage of interest.
