What Vehicles Are Included in Motor Vehicles?

According to the national standards for motor vehicle safety inspection, motor vehicles can be classified into the following types: Large automobiles: Refers to various vehicles with a total mass exceeding 4,500 kilograms, or a vehicle length of 6 meters or more, or a seating capacity of 20 people or more. Small automobiles: Refers to vehicles with a total mass of 4,500 kilograms or less (including 4,500 kilograms), a vehicle length under 6 meters, or a seating capacity of fewer than 20 people. Special-purpose vehicles: Refers to vehicles equipped with specialized devices and designed for specific purposes, including street sweepers, instrument vehicles, postal vehicles, and truck cranes. Special vehicles: Refers to emergency vehicles with special purposes, including fire trucks, ambulances, engineering rescue vehicles, security vehicles, and accident investigation vehicles. Trams: Refers to vehicles powered by electric motors, equipped with trolley poles, and running on tracks. Trolleybuses: Refers to vehicles powered by electric motors, equipped with trolley poles, and fitted with tires or wheels. Battery-powered vehicles: Refers to vehicles powered by electric motors using batteries as the power source. Three-wheeled motorcycles: Refers to motor vehicles with three wheels and a total mass under 750 kilograms. Motorcycles also belong to motor vehicles.

How Many Years Can a Car Last?

Generally, a car can be used for about ten years. Below is an introduction to car lifespan and maintenance: Car Lifespan: The average lifespan of a regular car is approximately 5-10 years. After this period, the car's performance becomes less stable, fuel consumption increases, and components begin to age, leading to higher usage and maintenance costs for the owner, as well as inevitable inconveniences. Car Maintenance: Annual inspections are necessary. The standard for vehicle inspections is once every 6-15 years, once every 15-20 years, and four times a year for cars over 21 years old. Additionally, performing deep maintenance annually helps minimize damage to the car.

How Long Does It Take to Check Traffic Violations?

Violation records can generally be checked within three days. Here are the details about violation inquiries: Methods to Check Violations: You can check violations through the "Traffic Management 12123" app, or by logging into the official websites of local public security traffic management bureaus. Locate the vehicle violation query section, enter your license plate number and engine number to check. Alternatively, you can visit the service halls of local traffic police branches to inquire using terminal machines. Violation Processing Time: There is usually a delay of half a day to a full day. It's possible that the information might not update immediately due to network delays after paying the fine. If the violation record still hasn't been cleared after some time, vehicle owners are advised to recheck through the app to ensure there are no other unpaid fines. If none are found, they can verify the query results at the traffic police station.

What is the Principle of a Chassis Dynamometer?

The basic principle of a chassis dynamometer is to use rollers to simulate the road surface. The various resistances encountered by a vehicle during normal constant-speed driving are simulated through a loading device. The torque and power of the chassis dynamometer are measured by a force sensor installed on a force arm connected to the stator and the dynamometer housing. The fundamental principle of a chassis dynamometer is to simulate the various resistances encountered by a vehicle during normal constant-speed driving through a loading device, allowing the vehicle to accelerate and coast. The resistance experienced by the road surface is simulated using the rotational inertia of a flywheel assembly. By simulating the vehicle under various operating conditions on actual roads, the chassis dynamometer can test the vehicle's performance in terms of fuel economy, reliability, emissions, and power. The key to accurately simulating road resistance lies in the rational design of the dynamometer's loading system, as the control effectiveness of the loading system directly affects measurement accuracy. Automotive Chassis Construction: The automotive chassis structure consists of four parts: the running gear, transmission system, braking system, and steering system. Most modern passenger cars use independent suspension systems, which can be further categorized into longitudinal arm, transverse arm, multi-link, strut, and MacPherson suspension systems based on their structural forms.

Do I need to change the registration certificate for a white car with laser white wrap?

A white car with laser white wrap requires a registration certificate change. Additionally, vehicles with laser white wrap may not pass the annual inspection, but regulations may vary by region. It is recommended to consult the local vehicle management office before making any changes. Similar color distinctions: For example, there are various shades of red—bright red, wine red, French red, etc.—but on the vehicle registration certificate, they are all simply labeled as red. Similarly, white comes in many shades, such as taffeta white, pearl white, moonlight white, and beige white, but on the registration certificate, they are all marked as white. You can file for a record change: Of course, if the owner is unsure, it is also advisable to file for a record change. If the vehicle's color is changed from another color to white, such as from dark gray to red or from silver gray to sea blue, the difference in color is significant enough to require filing for a record change. This is no longer just a shade variation but a change in the color category, which must be documented. Otherwise, the vehicle will not pass the annual inspection.

What Are the Types of Automotive Batteries?

Power batteries include lithium manganese oxide batteries, lithium iron phosphate batteries, and ternary lithium batteries. Below are detailed introductions: Characteristics of lithium manganese oxide batteries: Lithium manganese oxide batteries have low cost, good safety, and excellent low-temperature performance. However, the material itself is unstable and prone to decomposition, which can generate gas. Therefore, it is often mixed with other materials to reduce cell costs. Characteristics of lithium iron phosphate batteries: They offer good thermal stability, high safety, low cost, long lifespan, and low energy density. They are resistant to low temperatures and have a long service life, but the vehicle's range is generally limited. Charging efficiency decreases when the temperature drops below -5°C, making them unsuitable for winter charging needs in northern regions. Characteristics of ternary lithium batteries: Ternary lithium batteries have high energy density, long cycle life, and resistance to low temperatures. However, they exhibit insufficient stability at high temperatures. While they can achieve the highest energy density, their high-temperature performance is relatively poor. Pure electric vehicles with range requirements are the mainstream direction, as these batteries are more stable in low temperatures, making them suitable for northern climates.
