How to Use the First, Second, and Third Gears in an Automatic Transmission?

Can You Buy a Car That Has Been in Stock for Over Two Years?

It is not recommended to purchase a car that has been in stock for over two years. While stock cars can be bought, it is advisable to avoid those with excessively long storage periods, preferably keeping the car's age within one and a half years. For cars stored for more than one and a half years, the aging of various components has reached a significant level, and some wear-prone parts may even be out of warranty, making them not worth buying. Many stock cars are unpopular models, which not only require more effort in future maintenance but may also have parts that are hard to find. If you do purchase a stock car, it is recommended to perform an initial maintenance check. If the stock car is over a year old, it is advisable to conduct the first maintenance immediately after purchase, including changing the engine oil and oil filter. For cars stored for even longer periods, additional checks should be performed on the coolant, brake fluid, rubber components, battery, tires, etc., and the fuel tank, fuel lines, and fuel injectors should be cleaned to ensure smooth fuel flow.

How to Repair Scratches on Car Glass?

Methods for repairing scratches on car glass are as follows: 1. Clean and wipe the area around the scratch. 2. Use tape to surround the scratch and define the repair area. 3. Use a grinding pad to grind away the scratch, then polish the glass with polishing paste. 4. Squeeze the glass scratch repair agent into the crack and let it penetrate. 5. Apply a small amount of toothpaste to the scratch, wipe with a soft cloth, and rinse with water. Car glass maintenance methods are as follows: 1. Use dedicated or suitable wiper blades and replace them in time. 2. Keep the front windshield clean. 3. Use car-specific glass cleaner.

Can a new energy vehicle be started while charging?

New energy vehicles can be started while charging, but cannot be shifted into gear for driving. When starting the vehicle during charging, the air conditioning can still be used normally. However, since electric air conditioning has high power consumption, using it while charging will reduce the charging power and prolong the charging time. If the discharge power exceeds the charging power, it may lead to battery depletion and potential internal damage, which would shorten the battery's service life. Electric vehicles have two batteries: the power battery and the starter battery. The starter battery mainly provides power for electronic devices other than high-power components like the motor and air conditioning, such as headlights, central control, wipers, door locks, horns, and brakes. The starter battery also has capacity limitations, and if power is continuously consumed without replenishment, the battery may be drained.

Is the Automotive Reducer Located Inside the Transmission?

The automotive reducer is located inside the transmission. The reducer serves two main functions, as follows: 1. Changing the direction of power transmission. 2. Acting as an extension of the transmission to provide a common gear ratio for all gears. Below are the structural classifications of reducers: 1. Cylindrical gears. Simple in structure and easy to manufacture, helical cylindrical gears are commonly used. Cylindrical gears are often employed in the main reducer when the engine is transversely mounted, in wheel-side reduction, or in two-stage main reducers. 2. Spiral bevel gears. The transmission feature is that the axes of the driving and driven gears intersect perpendicularly at one point, requiring high installation precision, and are used in longitudinally mounted engine applications. 3. Hypoid gears. The transmission feature is that the axes of the driving and driven gears are perpendicular but do not intersect. 4. Worm gears. Suitable for longitudinally mounted engine applications but less commonly used.

Automatic Transmission: One Foot or Two Feet?

Automatic transmission uses one foot. Here are the relevant details: 1. Automatic cars do not have a clutch pedal, only brake and accelerator pedals. 2. When driving an automatic car, you need to use your right foot to operate both the brake pedal and the accelerator pedal. The left foot should remain stationary on the left side. 3. Using the left foot for braking and assigning each foot its own function helps form simple conditioned reflexes, preventing missteps, and the feet do not need to change positions. According to the Taiwan Vehicle Research and Testing Center, the time to switch from the accelerator pedal to the brake pedal is approximately 0.15-0.25 seconds.

Can an Inter-Axle Differential Lock Turn?

An inter-axle differential lock can turn. The purpose of a differential lock is to enhance a vehicle's off-road capability by quickly locking the differential when one driving axle spins freely, thereby rigidly connecting the two axles. Differential locks can be categorized into the following types based on their locking mechanisms: 1. Forced Locking Type: This type uses a simple, easy-to-manufacture locking mechanism on a standard symmetrical bevel gear differential, offering high torque distribution but requiring the vehicle to stop for operation. 2. High-Friction Self-Locking Type: Includes friction disc and sliding cam designs, commonly found in passenger and light vehicles for smooth operation. 3. Dog Clutch Type: Typically used in medium and heavy-duty trucks. 4. Torsen Type: A modern inter-axle differential utilizing worm gear mechanics for self-locking, compact design, and adjustable torque, widely used in all-wheel-drive vehicles. 5. Viscous Coupling Type: Some 4WD vehicles use silicone oil-filled couplings that lock when temperature rises due to speed differences between axles.
