There are four types of automatic transmissions: AT, CVT, AMT, and DCT. Hydraulic Automatic Transmission (AT) achieves automatic shifting through a combination of hydraulic drive and planetary gears. It consists of a torque converter, planetary gear mechanism, shift actuator, shift control system, and shift operation mechanism. Continuously Variable Transmission (CVT) operates over a continuous range of ratios, better coordinating the vehicle's external driving conditions with engine load. Automated Manual Transmission (AMT) is an improvement over the traditional manual gear transmission, combining the advantages of both AT (automatic) and MT (manual) transmissions into an electromechanical-hydraulic integrated automatic transmission. Dual-Clutch Transmission (DCT) uses two sets of clutches that alternate to achieve seamless shifting. DCT combines the advantages of AT and AMT, offering high transmission efficiency, simple structure, and lower production costs.

Can the Car Continue to Drive After the Oil Change Reminder?

After the oil change reminder, the car cannot continue to drive. The reasons are as follows: 1. The oil change reminder indicates that the oil's effectiveness has declined after a period of use; the lubrication and cooling functions are reduced. Continued use will damage the engine, reduce its lifespan, increase the likelihood of problems, and consequently raise maintenance costs. 2. If the car is low on oil, you should quickly purchase oil from the nearest auto parts store and add it temporarily. If you continue to drive without sufficient oil, the lack of lubrication will cause the engine's components to rub against each other and become damaged.

How to Open the Fuel Tank on a Spirior?

With the car doors unlocked, simply press the fuel tank cover and it will pop open. Here are some related details: 1. The Spirior has a fuel tank capacity of approximately 70 liters. There is no dedicated fuel tank cover switch - when all door locks are disengaged, pressing the fuel tank cover opens it. To close, simply push it shut. When the vehicle is fully locked, the fuel tank cover automatically locks as well. 2. The Spirior's overall body shape forms a wedge profile - wide with a low center of gravity. The forward-leaning waistline extends to the wheel arches, a design that reduces air resistance during motion. The sharply angular body enhances its sporty character with thorough refinement. 3. The front bumper's lower air intake and airflow channels direct cooling air straight to the radiator, improving heat dissipation while progressively revealing the car's sporty nature. To further emphasize this athletic character, the Spirior comes with 17-inch 10-spoke aluminum alloy wheels that maintain excellent ventilation and cooling even during extreme maneuvers.

What causes oil leakage after a motorcycle falls over?

There are several situations where oil leakage occurs after a motorcycle falls over: carburetor leakage and fuel spillage from the fuel tank. Methods to handle motorcycle oil leakage: First, clean the motorcycle's engine, then use aluminum repair agent to fix the leaking area. If this does not resolve the issue, promptly send it to a repair workshop for maintenance. Reasons for carburetor leakage: Because the motorcycle carburetor usually maintains a constant liquid level in the float chamber, if the vehicle falls, the liquid level will rise, causing fuel to flow out through the carburetor return pipe. Since carburetor motorcycles rely on gravity for fuel supply, the float in the float chamber is linked to a switch that controls the amount of gasoline entering the carburetor. If the switch fails, gasoline will continuously enter the carburetor under gravity, flowing into the engine intake and air filter. Therefore, an overflow pipe is designed to discharge excess gasoline through the pipe below the carburetor when the float switch fails to close. Fuel spillage from the fuel tank: This phenomenon generally occurs on motorcycles that have had their fuel tank caps replaced. If it is the original fuel tank cap, only a small amount will leak out slightly because the fuel tank cap has an exhaust hole.

What are the symptoms of engine knocking?

The following are the symptoms of engine knocking: 1. When slight knocking occurs, the engine will produce crisp and discontinuous metal knocking sounds; 2. In cases of severe and continuous knocking, the engine will emit continuous metal knocking sounds, accompanied by a noticeable decrease in engine power. Here are some precautions to prevent engine knocking: 1. First, use fuel with the correct octane rating. Using fuel with too low an octane rating may cause carbon buildup and knocking, but using fuel with too high an octane rating will not alleviate knocking. 2. Drive as standardly as possible, adopting correct driving habits to prevent excessive carbon buildup in the engine. Regularly inspect the engine's ignition system and clean carbon deposits from the cylinders periodically. Especially when the engine emits abnormal noises under specific conditions, immediate inspection is essential to ensure safety.

What to Do When the Car Suddenly Stalls?

If the car suddenly stalls while driving, depending on the road conditions at the time and if there is no emergency, you can slowly apply the brakes to prevent a rear-end collision. After reducing the speed, steer slowly to move the car to the roadside lane. Once parked by the roadside, turn on the hazard lights, place the warning triangle, and call for a tow truck. Common reasons for stalling are as follows: 1. Stalling caused by carbon deposits: Especially at the electronic throttle, this is an intake system issue. When there is excessive carbon buildup at the throttle, releasing the accelerator while driving may cause the car to stall, which often happens in very old cars. However, this can be prevented. Normally, you may notice difficulty starting the car, or even needing to press the accelerator to start it, which is a sign of excessive carbon deposits at the throttle and requires timely cleaning. 2. Fuel supply failure: Usually caused by a damaged fuel pump, which cannot pump fuel. The fuel pump has a long lifespan, so damage generally occurs in older cars. Some cars may fail to start when parked due to a faulty fuel pump, while others may stall while driving. 3. Power supply failure: Typically caused by a damaged ignition coil, resulting in no high-voltage electricity to all spark plugs.
