Which is better, AT transmission or DCT?

DCT is better. AT technology is more mature than DCT technology, with Japan's Aisin 6AT being the most widely used currently. DCT refers to dual-clutch transmission, which is divided into dry and wet types. Some high-end models generally use wet DCT because it has shorter shift times, matches the engine more perfectly, resulting in less shift jerkiness and better fuel efficiency. However, most models currently use dry DCT. Below are the advantages of AT and DCT: 1. Advantages of AT transmission: Mature technology, AT transmission is the most widely used and popular transmission on the market today. Traditional hydraulic automatic transmissions use a torque converter (or hydraulic coupler, multi-plate clutch, etc.), which can buffer engine power shocks and, combined with planetary gears, offers stable performance. It can also handle high torque. Even tanks have models equipped with AT transmissions. 2. Advantages of DCT transmission: Smooth shifting without the jerkiness common in general automatic transmissions. It is fuel-efficient and can efficiently utilize the kinetic energy generated by the engine, featuring advanced technology.

Should I choose 0w20 or 5w20 for Corolla?

Whether to choose 0w20 or 5w20 engine oil for Corolla mainly depends on the vehicle's usage environment: 1. If you are in the northern region with colder weather, 0w20 engine oil is recommended. 0w20 oil has better low-temperature fluidity and cold resistance than 5w20. 2. If you are in the milder climate of the southern region, 5w20 is completely sufficient. Here is some relevant information about engine oil: 1. The number before W represents the oil's cold resistance. For example, 0W oil will freeze at -35°C, while 5W oil will freeze at -30°C. 2. The low-viscosity grades of engine oil are 0W, 5W, 10W, 15W, 20W, and 25W. The smaller the number, the better the low-temperature cold start performance. The viscosity grades at 100°C are 20, 30, 40, 50, and 60, with higher numbers indicating higher viscosity.

Can Manual Transmission Use Automatic Transmission Fluid?

Manual transmissions cannot use automatic transmission fluid for the following reasons: The viscosity of manual transmission fluid is higher than that of automatic transmission fluid, which helps to better lubricate the friction surfaces of manual transmission gears. The fluidity of automatic transmission fluid is higher than that of manual transmission fluid, allowing for faster and more stable transmission of engine power. The heat dissipation capability of automatic transmission fluid is superior to that of manual transmission fluid, preventing excessive temperatures that could reduce lubrication effectiveness and damage moving parts of the automatic transmission, such as causing component jamming, clutch slippage, or seal leakage. The methods for changing transmission fluid are as follows: Loosen the drain screw at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it allows for the removal of impurities at the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: A smart circulation machine can perform dynamic fluid changes, filtering and cleaning sludge and impurities inside the automatic transmission.

What are the differences between Goodyear's first and second generation?

Goodyear's EfficientGrip first and second generations mainly differ in tread density, drainage groove pattern direction, and comfort level. The specific differences are as follows: Different tread density: The first generation has a higher tread density than the second generation, but the first generation's lateral grooves are smaller, about 1 millimeter in width, while the second generation's lateral grooves are larger compared to the first generation. Different drainage groove pattern direction: The first generation's central drainage groove pattern is in opposite directions, while the second generation's central drainage groove pattern is in the same direction. Different comfort level: The second generation is an upgraded version of the first generation, offering quieter and more comfortable performance. This is because the second generation is a tire specifically designed for luxury cars, featuring quiet and comfortable performance with excellent wet braking performance. The innovative tread and carcass design, advanced shock-absorbing carcass, and silica compound formula provide drivers with a quiet and comfortable driving experience.

What Causes the Friction Noise When the Car is Cold but Disappears When Warm?

There are several reasons why a car may produce friction noises when cold but the sounds disappear when warm, including issues with the generator belt or fuel pump failure. The specific causes are as follows: Generator Belt Issues: When the car is cold (including during a cold start), the noise from the belt can play a significant role in the overall vehicle noise. If the belt becomes loose and slips severely, it may produce a noticeable grinding sound. Additionally, the belt tends to be harder at low temperatures, which can result in a squeaking noise. However, at higher temperatures, the belt's improved elasticity reduces friction noise. Fuel Pump Failure: A "squeaking" sound similar to an electric current when the car is cold, after ruling out noise caused by belt or fuel line resonance, may indicate a fuel pump failure. A faulty fuel pump can lead to low fuel pressure and poor atomization from the injectors, resulting in an imbalanced air-fuel mixture and incomplete combustion.

What are the size specifications of a flatbed transport vehicle?

Freight flatbed truck standard dimensions are as follows: 1. Width: Generally speaking, vehicles of the same tonnage may not have identical cargo compartment dimensions, but large trucks are typically 2.3-2.4 meters wide, with a minimum width of 2.3 meters. 2. Length and height: Usually range from 8 meters to 10 meters, or even up to 12.5 meters. For non-containerized vehicles, the top of the cargo is generally 4.2 meters above ground, with a maximum height of 4.5 meters. Additional information: Flatbed trucks are a common type of road transport vehicle, favored by transport companies because they facilitate the loading and unloading of large, heavy goods and can carry more cargo than other vehicle types of the same specifications. In the transport vehicle category, flatbed trucks are generally divided into two types: flat and high-low deck. Flatbeds are usually 4 to 13 meters long, while vehicles longer than 13 meters are mostly high-low deck types.
