What Are the Common Faults of Manual Transmissions?

Manual transmission is a speed-changing device used to alter the speed and torque transmitted from the engine to the driving wheels. Common faults of manual transmissions are as follows: 1. Transmission noise phenomenon: (1) Transmission noise refers to abnormal sounds emitted during the operation of the transmission. (2) Causes: Gear noise due to excessive wear, thinning of gears, excessive clearance causing impact during operation; poor meshing of gear surfaces, such as not replacing gears in pairs during repairs. 2. Transmission oil leakage phenomenon: (1) The appearance of lubricating oil around the transmission and a decrease in the oil level in the transmission gearbox can be judged as lubricating oil leakage. (2) Causes and solutions: Improper selection of lubricating oil, generating excessive foam, or excessive lubricating oil volume, in which case it is necessary to replace or adjust the lubricating oil. 3. Transmission jumping out of gear: When an electric vehicle is driving in neutral, rapidly pressing the accelerator pedal or the electric vehicle being subjected to impact causes the gear lever to automatically return to neutral, the sliding gear disengages from the meshing position, interrupting power transmission, which is known as gear jumping. This phenomenon often occurs when there is a sudden change in high-speed load or when the electric vehicle vibrates, with high-speed gear jumping being the most common.

What is a Hydrogen-Powered Vehicle?

Hydrogen-powered vehicles are automobiles that use hydrogen as their energy source, converting the chemical energy produced by hydrogen reactions into mechanical energy to propel the vehicle. Below is a relevant introduction to hydrogen-powered vehicles: Types of Hydrogen-Powered Vehicles: Hydrogen-powered vehicles are divided into two types: hydrogen internal combustion engine vehicles, which burn hydrogen (usually obtained by decomposing methane or electrolyzing water) in an internal combustion engine to generate power to drive the car, and hydrogen fuel cell vehicles, which use hydrogen or hydrogen-containing substances to react with oxygen in the air in a fuel cell to generate electricity that powers an electric motor, which then drives the vehicle. Advantages of Hydrogen-Powered Vehicles: The greatest benefit of using hydrogen as an energy source is that it reacts with oxygen in the air, producing only water vapor as exhaust, effectively reducing the air pollution problems caused by traditional gasoline-powered vehicles.

What is the best position to install ETC?

The ETC is generally installed in the upper middle part of the front windshield for most vehicles, while for large vehicles like trucks and buses, it is installed in the lower middle part. The suitable installation position should be at a height of no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with pre-installed or later-added explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is handled by a proxy, the proxy's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway toll fees is needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the original ID card of the proxy; the original vehicle registration certificate; and the vehicle for which ETC is to be installed. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many vehicle models have windshields with a large backward tilt angle, which reduces the driver's field of vision. If the ETC is installed without considering this, it may increase the driver's blind spot. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. Precautions for using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic toll deduction for the wrong vehicle. The ETC lane recognizes vehicles at a speed of 20 km/h. If the vehicle speed is too fast, the device information may not be read, leading to toll deduction failure. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.

How Many Days Does a Beginner Need to Get Familiar with the Feel of Driving?

Due to the varying levels of adaptability among beginner drivers, the time required to master the feel of driving can differ. Generally, it takes about one month to become familiar with the feel of driving. Beginner drivers should control their speed and try to drive on familiar roads while maintaining focus to better handle the vehicle. Appendix: Ways to Get Familiar with the Feel of Driving: 1. Following a Car: Whether driving in the city or on the highway, maintaining a proper distance is essential. Observe the following vehicle through the rearview mirror and combine speed, distance, and visibility. Practicing driving while following another car helps develop an initial feel for driving. 2. Speed Control: Beginner drivers often struggle with inconsistent speed, either too fast or too slow. When pressing the accelerator, they should do so gently and gradually, adjusting based on road conditions. Understanding speed changes through throttle control improves overall speed management. 3. Turning Feel: A common mistake among beginner drivers when taking curves is braking while turning or driving too fast and braking too hard. Therefore, when approaching a curve, they should slow down in advance. During the turn, coordinate the speed with the steering wheel's rotation angle. With more driving experience, they will learn how much to turn the wheel to position the car correctly.

What Vehicles Use Viscous Fan Clutches?

Vehicles that use viscous fan clutches are mostly off-road vehicles, trucks, semi-trailers, and heavy-duty trucks. The working process of a viscous fan clutch is as follows: 1. When the temperature of the air passing through the radiator increases: The bimetallic temperature sensor deforms due to heat, forcing the valve shaft to rotate and open the oil inlet hole on the driven plate. The silicone oil stored between the driven plate and the front cover then flows into the working chamber between the driving plate and the driven plate, engaging the clutch and increasing the fan speed. The higher the air temperature, the larger the opening of the oil inlet hole, and the faster the fan speed. 2. When the temperature of the air passing through the radiator decreases: The bimetallic temperature sensor returns to its original state, the valve closes the oil inlet hole, and under centrifugal force, the silicone oil flows back from the working chamber to the oil storage chamber through the oil return hole, disengaging the clutch and reducing the fan speed to a very low level.

What Does Driving Mode Mean?

This can be understood as 'driving mode'. Driving mode can be divided into two concepts: the driving mode of a mobile phone and the driving mode of a car. 1. Mobile phone driving mode: Mainly used while driving, its purpose is to facilitate the driver, allowing them to focus more on driving. For example, during driving, if there is an incoming call or a new text message, it will be automatically read out, eliminating the need for the user to manually check. Alternatively, it integrates commonly used functions such as navigation, phone calls, and music into one interface with enlarged fonts, allowing users to quickly and clearly select and access them. 2. Car driving mode: It can be understood as the car having different 'identities'. Each time a mode is switched, the car's performance focus changes. Common driving modes include: Economy (ECO) mode, Sport mode, Standard mode, and Comfort mode. For off-road vehicles, there are also modes like Mud mode, Sand mode, and Rock mode. For example, when switching to Sport mode, the car's suspension becomes stiffer, and the transmission delays upshifting to achieve more powerful performance.
