Can I switch to an automatic transmission during driving lessons?

Generally, the boundary is marked by Subject 1 of the driving test. If you have registered for a manual transmission driver's license test (C1), you can change to an automatic transmission driver's license test (C2) by completing the relevant procedures with the driving school and paying the additional fees, provided you have not taken the Subject 1 exam yet. Here is an introduction to the advantages and disadvantages of automatic transmission: 1. Advantages of automatic transmission: It is simple and easy to operate, saving both effort and worry; it enhances driving safety, reduces the driver's operational intensity, and improves passenger comfort; it extends the service life of mechanical components, improves the vehicle's power performance, and reduces air pollution. 2. Disadvantages of automatic transmission: The structure is relatively complex, requiring high manufacturing precision. Due to its complexity, fault analysis and maintenance are more challenging, and the price is higher, resulting in higher usage and maintenance costs. Automatic transmissions are relatively more fuel-consuming than manual transmissions because they rely on a torque converter to transmit power, which incurs some efficiency loss compared to the mechanical transmission of manual transmissions, typically consuming 5%~10% more fuel. Due to hydraulic power transmission, automatic transmissions exhibit a lag in acceleration, meaning both acceleration and deceleration are slower compared to manual transmissions. Additionally, the frequent and prolonged use of the foot brake leads to greater wear on the braking system.

What Does Hot Melt Tire Mean?

Hot melt tires refer to tires whose surface melts or becomes gel-like at certain temperatures. Specific details are as follows. Full Hot Melt Tires: Full hot melt tires refer to tires whose tread melts into a gel-like state when the temperature rises. When a vehicle is in motion, the tires continuously rub against the ground, generating heat in the tread. Compared to the rubber in a cold state, it becomes more fluid, meaning it softens. The softened tires enhance adhesion to the ground, thereby improving the vehicle's cornering limits. Generally, full hot melt tires are more commonly used in racing cars and are relatively expensive. Semi-Hot Melt Tires: Due to the high cost of full hot melt tires, semi-hot melt tires were developed. Tire manufacturers add chemical materials such as Kevlar fibers during production, which strengthens the sidewall hardness while reducing weight. These tires operate at much lower temperatures than full hot melt tires but still retain some hot melt characteristics. Combined with tread pattern and drainage groove designs, they can achieve grip levels close to those of full hot melt tires.

What to Do If the Expressway Card Is Lost?

When passing through the expressway toll station, inform the staff about the specific situation. They can retrieve surveillance footage based on the license plate number to check the vehicle's entry information and travel route. If the actual entry information is verified, the toll will be charged accordingly. If the actual entry information cannot be identified, the vehicle owner will be responsible for paying the full toll from the point of entry to the exit. Here is some relevant information about expressway toll cards: 1. Expressway Toll Card: The expressway toll card is established to shorten the query time. Every expressway toll station is equipped with electronic cameras, and all vehicle records can be retrieved by checking the surveillance footage based on the license plate number. 2. Smart Toll Card: If the smart toll card (IC card) is lost or physically damaged, resulting in the inability to identify the actual entry information, the driver should compensate for the cost of the card. For drivers who do not have a card, if they wish to apply for one, they can bring their driver's license, vehicle registration, and ID card to the relevant department for processing, or they can go to certain banks to apply.

How Long Does the German Sunshine Battery Last?

German Sunshine batteries can last up to 7 years. Under standard usage conditions, they can cycle 5,500 times at 25% DOD. The following factors affect battery lifespan. Terminal Fracture: Due to long-term neglect of maintenance, issues such as corrosion of terminal bolts making them immovable or gaps forming between terminals and posts preventing tightness often occur. Drivers typically use hammers or wrenches to forcibly tighten terminal clamps by striking them downward, or insert metal shims into gaps between clamps and posts to secure them. This rough maintenance method can easily cause cracks between posts and connecting plates, or between connecting plates and plates themselves. Larger cracks may lead to open circuits, while smaller ones increase resistance, preventing normal battery discharge. Casing and Seal Cracking: Agricultural vehicles like tractors often operate on bumpy roads. If the battery is not securely installed, it can easily detach or get damaged. During installation, rubber pads or wooden blocks should be placed under and around the battery before securing it firmly as required. Seal cracking is mostly caused by surface exposure to oils that degrade rubber. Therefore, the battery surface should be frequently wiped clean to maintain cleanliness.

Is a tire pressure of 1.4 bar indicating a puncture?

A tire pressure of 1.4 bar might be caused by a nail puncture or other reasons leading to air leakage. It is recommended to first check if there is a nail in the tire, reinflate it, and observe whether it loses air quickly. If the air loss is rapid and no nail is found, visit a service station when possible to diagnose the issue. Risks of overinflated or underinflated tires: For tires, the pressure should neither be too high nor too low. Overinflation reduces the contact area between the tire and the ground, leading to poor grip, which affects the vehicle's handling and driving stability. Underinflation can cause wave-like deformation during high-speed driving, reducing the tire's lifespan and increasing the risk of a blowout. Standard tire pressure guidelines: According to the international GBT2978-2008 standard, the recommended tire pressures are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar.

How many kilometers can 37 liters of fuel run?

37 liters of gasoline can approximately run 550 kilometers. The factors affecting a car's fuel consumption are as follows. Engine displacement: Different cars inherently have different fuel consumption rates. Generally, SUVs consume more fuel than regular sedans. When purchasing a car, you can choose a vehicle with lower fuel consumption. Fuel consumption is related to engine displacement. A 1.0-liter displacement car typically consumes about 5 liters per 100 kilometers, while a 1.5-1.6-liter displacement car consumes about 7 liters per 100 kilometers. Car shape: This is mainly due to wind resistance. The greater the wind resistance, the higher the fuel consumption. A significant portion of wind resistance is influenced by the car's shape. Reducing wind resistance by about 10% can decrease fuel consumption by approximately 3%. Carbon deposits in the transmission: Carbon deposits in the transmission can reduce engine power and, to some extent, lead to increased fuel consumption. This is because, to achieve the same power as before the carbon deposits formed, it is necessary to increase the throttle opening and corresponding fuel supply.
