What vehicles can a Class B license drive?

A Class B license allows driving the following vehicles: 1. For B1, the permitted vehicle type is medium-sized passenger vehicles (including urban buses with a capacity of 10 to 19 people); 2. For B2, the permitted vehicle types are heavy and medium-duty trucks, such as large trucks carrying construction waste, and large, heavy, or medium-sized specialized operation vehicles, such as water sprinklers, concrete mixers, and fire trucks; 3. Both licenses also permit driving vehicles under Class C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery). A B1 driver's license cannot be directly applied for, but one can apply for an upgrade at their registered residence one year after obtaining a B2 license (provided there is no full-point record in the most recent scoring cycle before application). Alternatively, one can apply for an upgrade after holding a small car driving qualification for more than three years.

How many kilometers should car brake pads be replaced?

Car brake pads are generally replaced every 50,000 kilometers. Whether the brake pads need replacement can be determined by their thickness, sound, and pedal feel: 1. Thickness: Normal brake pads have a thickness of about 10mm, and they should be replaced when the thickness is below 6mm; 2. Sound: If the car frequently makes abnormal noises during braking, it indicates severe wear of the brake pads, which also requires replacement; 3. Pedal feel: When the brake pads are severely worn, their braking force decreases, so symptoms of weakness will be noticeable when stepping on the brake, necessitating timely replacement. The brake pads should be inspected and maintained every 20,000 kilometers. During daily use, avoid sudden braking and stopping to prevent accelerated wear of the brake pads, and avoid water immersion to prevent corrosion of the brake pads.

What does automotive PCB mean?

Automotive PCB stands for printed circuit board, also known as printed wiring board. Here is an introduction about the types of automotive PCBs: Flexible PCB: These boards are made with flexible plastic substrates, composed of PEEK, polyamide or transparent polyester film. These boards can be twisted and bent. Used in automotive curves and corners. Rigid PCB: Rigid boards are made of FR4. These boards are inflexible. Typically used in displays and rearview camera screens. Rigid-flex PCB: These boards combine features of both rigid and flexible circuit boards. Implemented in lighting systems. HDI-PCB: These boards feature higher wiring density per unit area, finer lines and spaces, and higher pad connection density. HDI boards can accommodate more components and play an important role in miniaturization. These boards are widely used in infotainment systems. LED-PCB: LED substrates are made with aluminum base due to heat dissipation requirements. Can be found in automotive indicators, headlights and brake lights.

Can Toilet Water Be Kept in the Car?

Toilet water should not be kept in the car because it contains a relatively high amount of ethanol, which is highly volatile. Additionally, toilet water has a low ignition point and is prone to combustion. Below are some important considerations regarding items placed in the car: Flammable Items in the Car: Items such as car perfumes and lighters are flammable, especially during hot summer months. Due to high external and internal temperatures, these items can easily explode or catch fire. Items Not Suitable for Placement: Decorations with sharp edges should not be placed in the car, as they can pose a risk of injury in case of an accident. It is recommended to avoid placing or hanging items in the car, as they may shake or fall during driving, distracting the driver and obstructing the view, thereby creating safety hazards. Electronic devices should also not be left in the car, as high temperatures can cause batteries to swell or even explode. Therefore, avoid placing mobile phone batteries, digital camera batteries, or similar items in the car, especially on the dashboard under direct sunlight or on the storage shelf between the rear seats and the window.

What are the hidden dangers of replacing the valve cover with aluminum alloy?

The replacement of the valve cover with aluminum alloy poses no safety hazards. Below are relevant details about the valve cover: Function: The primary role of the valve cover is to protect the engine camshaft while forming a nearly enclosed cavity together with the cylinder head. Inside, there are oil return and supply passages connected to the cavity. The valve cover effectively prevents dust from contaminating the engine oil or entering to accelerate wear on valve train components. Therefore, it is necessary to regularly inspect the sealing condition of the valve cover. If oil leakage is detected, timely action should be taken to ensure the engine's durability. Sealant Application: If oil leakage issues are resolved after replacing the gasket, applying sealant is entirely unnecessary. However, if leakage persists post-gasket replacement, applying sealant can enhance the sealing of the valve cover. If necessary, the valve cover itself can also be replaced. Note that applying sealant may complicate future valve cover replacements, as the sealant must first be removed, potentially increasing repair costs.

What is the main function of a car differential?

Here is an introduction to the main functions of a car differential: Power transmission: Transmits the power output from the engine to the wheels. Speed reducer: Divides the torque already increased by the main reducer into two parts and distributes it to the left and right half-shafts. Acts as the main reduction gear: Serves as the main reduction gear, reducing the speed of the drivetrain before transmitting power to the wheels, and allows the wheels on both sides to rotate at different speeds. When the car turns, the distances traveled by the wheels on both sides are unequal within the same time—the outer wheel moves a greater distance than the inner wheel. As a result, the planetary gears on the differential cross shaft are affected by the resistance of the wheels. While revolving, they also rotate on their own, automatically increasing the speed of the outer wheel, speeding it up, and slowing down the inner wheel, thus performing the differential function.
