There are two methods to distinguish: 1. Check the "Automobile Fuel Consumption Label" attached to the new car. 2. Look at the vehicle's nameplate to find the "Vehicle Model," which is a combination of numbers and letters, and also locate the engine model of the new car. Then, log in to the Motor Vehicle Environmental Protection Website, enter the vehicle model and engine model to query. 3. China 5 and China 4 standards are differentiated based on the different emission pollution standards for vehicles. The China 4 emission standard is the national fourth-stage motor vehicle pollutant emission standard. China V is a grade of Beijing's motor vehicle emission standard, formulated and issued by Beijing's environmental protection department, equivalent to the Euro V standard, and was released in 2012.

Distinguishing between China 4 and China 5 vehicles is actually quite simple. I did my homework when I bought a car before. Just look at the vehicle's environmental protection label, which is usually stuck on the corner of the front windshield or included in the vehicle registration certificate, clearly marked as China 4 or China 5. The production date is also a reliable indicator—most vehicles produced before 2017 are China 4, while those after 2017 are mostly China 5. Another method is to check the VIN (also known as the chassis number). If the 10th digit is the letter '4,' it's China 4; if it's '5,' it's China 5. You can verify this by entering the VIN on the environmental protection bureau's official website. China 5 vehicles have lower emissions and are more environmentally friendly. In some major cities like Beijing and Shanghai, China 4 vehicles might face restrictions and be barred from entering core urban areas. So, clarifying this when buying a car can save you a lot of trouble and even increase resale value. Try to choose a China 5 vehicle—it's better for the environment too.

As a young person just learning about cars, I think distinguishing between China 4 and China 5 emission standards isn't difficult. The key is to check vehicle documents, such as the environmental protection standard section on the vehicle registration certificate, which clearly states whether it's China 4 or China 5. You can also look at the label near the engine hood - GB18352.4 indicates China 4, while GB18352.5 means China 5. China 5 vehicles are more popular in cities with strict air quality management as they can drive without restrictions. If still unsure, ask the seller or enter the license plate number in a car app for verification. This way, you won't worry about being deceived when buying used cars, and new cars will definitely comply with local regulations. Vehicles with higher environmental standards give more peace of mind when driving and are better for health and the environment.

I pay attention to environmental issues, and distinguishing between China IV and China V standards is quite simple. Just check the vehicle's environmental label, usually located in the upper left corner of the windshield or on the door frame, where the standard name is directly stated. The China V emission standard is stricter, reducing harmful substances, and only China V vehicles are allowed in pollution control zones. I recommend prioritizing China V vehicles to support urban cleanliness initiatives. Other methods include checking the production year information.

What is the general width of a car?

Width standard dimensions range from 1.6 meters to 1.8 meters. The actual considerations and variations in width are as follows: Practical considerations for width: Width primarily affects passenger space and flexibility. For passenger cars, if three seats arranged horizontally are required to have a spacious seating feel (mainly sufficient shoulder width), the car width generally needs to reach 1.8 meters. Due to safety requirements, the thickness of car door panels has increased, leading to a general increase in car width. Variations exist: It varies by car model, even the same car with different configurations, suspension stiffness, etc., all play a role. Generally, the length ranges between 3800mm to 4300mm, width between 1600mm to 1800mm, and height between 1400mm to 1600mm.

Function of CAN Transceiver

CAN transceiver serves as the bridge connecting the CAN control system with the CAN bus network. What parameters should be considered when selecting a CAN transceiver? This article will provide an in-depth understanding of each parameter of the transceiver and its significance in practical applications. Depending on the CAN interface voltage of the controller, you can choose a CAN module powered by 3.3V or 5V. The normal input range for an isolated CAN module is VCC±5%, mainly ensuring that the CAN bus voltage remains within the typical range while also allowing the secondary CAN chip to operate near its nominal supply voltage. For standalone CAN transceiver chips, the VIO pin of the chip needs to be connected to a reference voltage matching the TXD signal level to align the signal levels. If there is no VIO pin, the signal level should be kept consistent with VCC. When using the CTM series isolated transceivers, it is necessary to match the TXD signal level with the supply voltage, i.e., a 3.3V standard CAN controller interface or a 5V standard CAN controller interface.

Can a Vehicle Still Be Driven on the Road After Accumulating 12 Penalty Points?

Motor vehicles can still be driven normally. The main reasons and measures for continued driving are as follows: Main Reasons for Continued Driving: Traffic violation penalty points are assigned to the driver of the vehicle, not the vehicle itself. If a driver accumulates 12 penalty points within a scoring cycle due to driving a specific vehicle, the traffic police department will confiscate their driver's license. During the period of license confiscation, the driver is prohibited from operating any motor vehicle. Measures for Continued Driving: As for the vehicle itself, it will not be prohibited from being driven on the road simply because its driver has accumulated 12 penalty points. As long as there is a qualified driver, the vehicle can still be driven normally on the road.

What Are the Reasons Why a Forklift Fails to Start?

Forklift fails to start may be due to reasons such as an empty fuel tank, damaged fuel or electrical circuits, or a blown fuse in the high-pressure pump solenoid valve. The basic introduction to forklifts and the main reasons for failing to start are as follows: Basic Introduction: A forklift, also known as a loader, is a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is mainly used for shoveling and loading loose materials like soil, sand, gravel, lime, and coal. It can also perform light shoveling operations on ores and hard soil. By replacing different auxiliary working devices, it can also be used for bulldozing, lifting, and handling other materials such as timber. Main Reasons for Failing to Start: A forklift may fail to start due to reasons such as an empty fuel tank, damaged fuel or electrical circuits, or a blown fuse in the high-pressure pump solenoid valve.

Why does the dash cam automatically shut down right after startup?

Possible reasons include a faulty memory card, low battery, loose power connection, or software malfunction causing system lag. The specific causes are as follows: No memory card installed: Many dash cams may automatically shut down shortly after startup if no memory card is installed. If a card is installed, verify whether it is a Class 10 high-speed card. If not, replace it (this is highly relevant to the issue and should be prioritized). After confirming this, check again whether the battery is low. Faulty memory card: Due to prolonged use, memory cards can develop issues after repeated friction. In such cases, formatting the memory card on a computer usually resolves the problem. If it's a newly configured memory card, incompatibility might be the issue. Loose power connection: This is especially common when using a multi-port cigarette lighter adapter. When the power connection becomes loose, the dash cam will automatically switch to its built-in battery, which typically doesn't last long. As a result, the dash cam may appear to be on but is found to be off when checked later.
