Judging the national emission standard mark on a car is most straightforward by looking at the vehicle's environmental protection label. Below is relevant information on how to identify the national emission standard mark on a car: 1. Vehicle Environmental Protection Label: The simplest and most direct method is to check the vehicle's environmental protection label, which has a clear mark on the back. 2. Website Inquiry: Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. DMV Inquiry: Take the motor vehicle registration certificate (either the original or a copy) to the DMV for inquiry. 4. Vehicle Manufacturing Certificate: If it's a new car, you can look for the vehicle manufacturing certificate and check inside. However, generally, the certificate is kept at the DMV. Therefore, when purchasing a new car, it is advisable to make a copy for your records.

I've been driving for many years and found that checking the China emission standard label is actually quite simple. Usually, I can find a small label on the vehicle's windshield with markings like "China V" or "China VI" - that indicates the emission standard level. If you can't find it on the glass, you can check the vehicle registration certificate where the emission standard code (like China 5 or China 6) is listed in the registration information section. When some people forget the label location, I suggest they visit the DMV website and input the VIN for a free online query. It's important to pay attention to this label as it affects urban driving restrictions - some major cities only allow China 6 vehicles to enter, while China 5 or below may face fines. I recommend taking a photo of the label when you get a new car and saving it on your phone for reference in case the label wears off. This habit has saved me a lot of trouble. Always verify this before driving a newly purchased vehicle on the road.

I deal with this issue all day repairing cars, and customers often ask where to check the national emission standard. Simply put, look at the environmental protection label on the vehicle nameplate or the Certificate of Conformity. The nameplate is usually engraved with emission standard numbers like China V (Guo Wu) in the engine compartment or door frame. The certificate is given to the owner when buying a new car, clearly indicating the emission level. The national standard is crucial as it determines whether the vehicle can pass the annual inspection—for example, vehicles below China III (Guo San) might face difficulties. When I encounter older cars failing to meet emission standards, I have to advise customers to upgrade or replace parts. Additionally, scanning the vehicle with a diagnostic tool can display detailed information, including the national standard data. Beginners, don’t rely solely on labels during checks; it’s safer to have a technician verify during regular maintenance. In cities with traffic restrictions, it’s best not to drive vehicles below China V (Guo Wu) in the downtown area to avoid fines and penalty points. Remember, these small details affect driving costs and regulatory compliance.

How Do Traffic Police Determine Fatigue Driving?

Generally, a simple method for detecting fatigue driving in vehicles is by calculating the continuous driving time. Once it exceeds the preset duration in the system, an alarm will be triggered. Below is an introduction to the common fatigue monitoring systems equipped in vehicles: Definition: The commonly equipped fatigue monitoring system is known as the Fatigue Driving Warning System (BAWS). It is based on the driver's physiological image response, consisting of two main modules: the ECU and a camera. By utilizing the driver's facial features, eye signals, head movements, etc., it infers the driver's fatigue state and provides alarm prompts along with taking corresponding measures. This system offers active and intelligent safety protection for drivers and passengers. Function: Some fatigue monitoring systems in vehicles are referred to as the Fatigue Recognition System. It records the driver's operational behavior from the start of the journey and can determine the driver's fatigue level by identifying changes in driving operations during long trips. A decrease in the frequency of steering operations by the driver, accompanied by slight but abrupt steering actions to maintain the driving direction, is a typical indication of the driver's lack of concentration.

How Often Should the Car Engine Belt Be Replaced?

Generally, the car engine belt should be replaced every 2 years or 60,000 kilometers. A broken engine belt can lead to various malfunctions such as failure of the air conditioning system, power steering system, and power generation system. Methods to determine if the engine belt needs replacement: Touch by hand: Locate the engine belt and feel its inner side with your hand. If it feels rough like sandpaper, it indicates slight aging of the belt, but whether it needs replacement cannot be determined yet. Visual inspection under light: Use a flashlight to check if the outer nylon layer of the belt appears whitened. If there is only slight whitening that can be wiped off by hand, it is generally not a problem. However, if the whitened edges cannot be cleaned, it requires attention. Press by hand: The purpose of pressing the belt is to check the flexibility of the rubber belt. If the belt feels stiff like a stick with no flexibility, even without cracks or whitening, it is likely aged and hardened, and needs replacement.

Can the battery be charged when the car is idling with the engine on?

The battery can be charged when the car is idling with the engine running. Here are some tips about car battery charging and maintenance: Using high-power electrical devices connected directly to the battery: Many car appliances nowadays, such as car refrigerators and air pumps, have high instantaneous power consumption. Avoid powering them directly from the car battery. Instead, start the engine first before connecting these devices. This provides better protection for the battery. Turn off the air conditioning before shutting down the engine: If the air conditioning is left on when the engine is turned off, the system will automatically start working every time the ignition is switched on. This causes an immediate high power load on the vehicle, which can damage the battery over time. Turn off lights and other electronic devices when the vehicle is parked: If the vehicle's lights or other electronic devices remain on when the car is not running, the battery will continue to discharge. Prolonged discharge can significantly shorten the battery's lifespan.
