What are the classifications of transmissions?

Transmission classifications: manual transmission, automatic transmission, automated manual transmission, continuously variable transmission. Manual transmission: When shifting gears with a manual transmission, you need to depress the clutch, move the gear lever, and then release the clutch to complete the gear shift. Automatic transmission: A good automatic transmission shifts responsively with reasonable logic, achieving excellent fuel efficiency. Compared to manual transmissions, automatics offer more convenient operation as they generally don't require manual gear changes while driving. However, they have lower transmission efficiency, resulting in higher fuel consumption than manual transmissions. Automated manual transmission: An automated manual transmission is essentially a manual transmission with added control computers, typically featuring 5 speeds without D or P gears. Continuously variable transmission: A continuously variable transmission can achieve continuous changes in gear ratios, thereby achieving optimal matching between the transmission system and engine conditions. Its advantages include excellent smoothness, no jerking sensation, and strong driving comfort. The disadvantages are relatively poor torque-bearing capacity and slower response to speed changes.

There are many classifications of transmissions. The manual transmission is the earliest type, requiring you to press the clutch and shift gears yourself, offering strong driving control but beginners are prone to stalling. Automatic transmissions come in various types, including traditional torque converters, CVT, dual-clutch, and AMT. CVT uses a steel belt or chain for seamless shifting, providing ultra-smooth driving without jerking, making it ideal for city driving. Dual-clutch transmissions like DCT come in dry and wet types, offering fast shifting and excellent performance, commonly used in racing. AMT automatically controls manual structures, with low cost but noticeable jerking during driving. In terms of maintenance, manual transmissions have simple and durable structures, while automatics are more complex and prone to faults. The driving experience varies from person to person, so choosing a car requires a comprehensive consideration of fuel efficiency, comfort, and driving pleasure.

Which is quieter, Michelin 3st or 4st?

Michelin 4st has upgraded its noise reduction module, which noticeably reduces noise compared to the 3st during use, and also improves driving comfort. Here are the differences between the two: 1. Different drainage performance: Michelin Primacy 4 features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to the 3st, significantly reducing hydroplaning with excellent drainage. 2. Different rubber compound: Compared to the 3st, Michelin Primacy 4 adopts a new tread design and a new rubber compound, enhancing wet braking performance and rolling resistance for both new and worn tires. 3. Different safety performance: Due to the new rubber compound, Michelin's 4th generation offers excellent braking performance, with particularly outstanding wet braking. Official data shows that Michelin Primacy 4 outperforms the 3st by a full 2.4m in wet braking distance.

What are the techniques for parking in an angled parking space?

Techniques for parking in an angled parking space are: 1. Identify the parking space you want to enter and adjust the rearview mirrors; 2. When you see the inner rearview mirror aligned with the parking line, turn the steering wheel fully outward and proceed forward; 3. When the car body is longitudinally aligned with the parking space, stop the car and straighten the wheels; 4. Slowly reverse the car, smoothly entering the garage, then pull the handbrake and turn off the engine. Steps for holding the steering wheel in Subject 2: Hold the steering wheel symmetrically with both hands at the 9 o'clock and 3 o'clock positions, with thumbs naturally resting on the inner rim of the steering wheel. The advantage of the 9 and 3 o'clock grip is that it is parallel and symmetrical, providing significant protection for safe driving. When the vehicle needs to make an emergency avoidance, whether to the left or right, this grip allows for a large degree of steering.

What are the disadvantages of the Corolla?

Here are the disadvantages of the Corolla: 1. Transmission jerking and abnormal noise: The fatal flaw of the Corolla lies in the transmission's jerking and abnormal noise, especially during low-speed driving where the transmission's shaking and noise are more pronounced. 2. High failure rate of automatic headlight module: Additionally, the 2018 1.2T model has a high failure rate in the automatic headlight module. Many Corolla owners have complained about inaccurate headlight beam height when using automatic headlights, especially when there are passengers in the back seat, where the headlight beam tends to be too high, posing certain safety hazards. 3. Frequent Toyota turbocharger failures: Another issue is the existence of turbocharger failures in Toyota vehicles, which has become a common problem for turbochargers in general. As for whether the 1.2T can handle long-distance travel, the advice is not to recommend prolonged high-load operation of the turbo engine, as excessive turbocharger temperature can easily affect the lifespan of Toyota's 1.2T turbo. For those who frequently commute in the city, the 1.6L engine is a better choice, offering smoother performance.

How to Break in a Manual Transmission Car?

Manual transmission car break-in methods are: 1. The engine is not recommended to run at high RPM. For gasoline engines, keep it between 1500 to 3500 RPM, and for diesel engines, between 1200 to 2500 RPM. Driving within these RPM ranges can significantly reduce carbon buildup; 2. Warm up the car at low RPM before starting to allow the engine to fully preheat. Once the engine oil reaches temperature and flows to all parts of the engine, the protective film from the oil will minimize component wear; 3. Avoid excessive load. Load has a significant impact on a new car, and it is recommended not to exceed 70% of the maximum payload; 4. Avoid long-distance high-speed driving, as this can cause the engine to overheat from prolonged operation and affect its lifespan. While driving at medium to low speeds for extended periods, you can occasionally drive at higher speeds, but it is recommended not to exceed 100 kilometers per hour.

Where is the car fuse located?

Car fuses are located inside the fuse box under the dashboard trim panel, and there is also a fuse box in the front engine compartment. Every car has a fuse box, which contains fuses and relays. The fuses serve to protect the electrical circuits. There is an indicator diagram on the cover of the car's fuse box, which shows the corresponding number and function of each fuse. In the car's electrical system, many electrical devices are connected by wires of different colors, among which the fuse is an essential component. The term "fuse" is a customary name, while the national standard refers to it as a "circuit breaker." The function of a fuse is to protect the circuit (wiring) and electrical devices. Car fuses can be divided into blade-type fuses, glass tube fuses, and bolt-type fuses.

What does it mean when the engine malfunction indicator light flashes?

When the engine malfunction indicator light flashes, it could indicate a fault in one of the engine components. The engine fault warning light is triggered by the ECU (Engine Control Unit), which controls all electronic devices in the engine, such as the electronic throttle, fuel injectors, alternator, fuel pump, etc. If any of these systems malfunction, the engine warning light will illuminate. A continuously flashing engine malfunction light is abnormal. Sometimes no specific issue may be detected during inspection, which could be caused by internal wiring problems in the engine or system malfunctions. The ECU might generate error codes during computation, leading to the illumination of the engine warning light. Such fault codes need to be cleared at an authorized 4S dealership.
