The basic principle of a transmission is: 1. To use gear meshing transmission combinations with different numbers of teeth to achieve changes in speed and torque, thereby altering the speed and torque transmitted from the engine to the driving wheels; 2. To enable the car to obtain different traction forces and speeds during starting from a standstill, climbing, turning, and accelerating; 3. To keep the engine operating within a favorable working range. Transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions consist of gears and shafts, while automatic transmissions are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system. The functions of a transmission include: 1. Changing the transmission ratio to expand the range of torque and speed variation of the driving wheels; 2. Utilizing the reverse gear to enable the car to move backward while maintaining the same rotation direction of the engine.

How often should the CVT transmission fluid be changed for the 10th-generation Civic?

The transmission fluid should be changed every two years or every 40,000 kilometers. Below is an introduction to the Civic: 1. Exterior: The Dongfeng Honda Civic features a stylish and elegant appearance with smooth body lines. Its hatchback design has undergone significant changes compared to the previous model. 2. Interior: The interior of the Dongfeng Honda Civic is finely crafted with a fashionable design, offering a distinct sense of layering. It is equipped with a variety of functional configurations, although the extensive use of hard plastics results in a less premium feel. The seats provide good comfort. 3. Space: The Civic performs well in terms of space, with ample legroom in both front and rear seats. The front seats offer generous headroom, while the rear seats have slightly limited headroom. The central floor hump in the rear is not very pronounced, enhancing practicality. The storage compartments are functional, and the trunk space has been improved compared to the older model.

What is gear shifting called?

Gear shifting (or gear changing) refers to the transmission system, which is used to alter the torque and rotational speed of the engine crankshaft to meet the varying requirements of driving wheel traction and vehicle speed under different driving conditions such as starting, accelerating, traveling, and overcoming various road obstacles. More information about gear shifting is as follows: 1. Functions: It enables the car to drive at a very low and stable rotational speed, which is difficult to achieve solely by the minimum stable speed of the internal combustion engine; the reverse gear of the transmission allows the car to move backward; its neutral gear allows the engine to be separated from the drivetrain for extended periods when starting the engine, parking, or coasting. 2. Classification: Automatic transmission does not require the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Common automatic transmission gears include P, R, N, D, 3, 2, and 1; whereas manual transmission requires the driver to manually move the gear lever to change the gear meshing inside the transmission, altering the gear ratio to achieve speed changes. Manual transmission vehicles typically have gears labeled 1, 2, 3, 4, 5, N, and R.

How long does it take to pick up an Audi A4L?

Vehicle inspection, payment, insurance purchase, and temporary license plate application can usually be completed in one morning. Precautions for picking up the car: 1. Check the exterior: whether the white protective film is intact, whether there are scratches after washing, whether the paint is scratched, whether the tire hairs are neat and dense, and whether the interior (seats, center console, steering wheel, doors and windows, sunshade, etc.) is in good condition. 2. Check the air conditioning system: turn on the air conditioning to see if the buttons are flexible and if it can cool quickly. 3. Check the audio system: whether USB, radio, and CD are functioning properly, whether the sound is flawless, and whether the navigation is working. 4. Check the center console instrument display: generally, the mileage should not exceed 50-80 kilometers, and whether the screen display is normal. 5. Check various electronic functions: rearview mirror adjustment, seat adjustment and heating, memory, door and window lifting, sunroof adjustment, etc. 6. Check the engine compartment: whether it is clean, whether the windshield washer fluid and electrical system are intact, and the condition of engine oil and antifreeze.

What type of batteries are used in new energy vehicles?

Here is information about the batteries used in new energy vehicles: 1. Lead-acid batteries: Lead-acid batteries use lead oxide as the positive plate, sponge lead as the negative plate, and a sulfuric acid aqueous solution as the electrolyte. 2. Alkaline batteries: Alkaline batteries are composed of nickel-based materials and alkaline solution electrolytes, mainly including nickel-cadmium batteries, nickel-zinc batteries, and nickel-metal hydride batteries. Among these, nickel-metal hydride batteries have higher specific energy and are environmentally friendly compared to nickel-cadmium and nickel-zinc batteries. 3. Lithium-ion batteries: Lithium-ion batteries can be divided into two types: lithium-ion batteries and lithium polymer batteries. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, lithium iron phosphate, etc., while the anode materials mainly include graphite, lithium titanate, etc.

Is it necessary to change the oil when the system prompts?

When the system prompts for an oil change, it must be replaced. Below is relevant knowledge about the first maintenance: 1. 5000 kilometers: At 5000 kilometers, only the engine oil and oil filter need to be replaced, and the entire vehicle should be inspected for any leaks. 2. 10000 kilometers: At 10000 kilometers, the engine oil and oil filter need to be replaced. Clean the dust from the air filter and cabin air filter. 3. 18000 kilometers: At 18000 kilometers, the engine oil, oil filter, air filter, and cabin air filter need to be replaced. The throttle body and idle speed motor can be cleaned as needed. 4. 26000 kilometers: At 26000 kilometers, the engine oil and oil filter need to be replaced.
