Methods to determine which national emission standard a vehicle belongs to are as follows: 1. Check the back of the vehicle's environmental compliance label. 2. You can roughly estimate the vehicle's emission standard based on its manufacturing year. 3. Bring the vehicle registration certificate to the local vehicle management office for inquiry. 4. On the first page of the vehicle compliance certificate number, there is an emission standard description. Below is additional information about vehicle emission standards: 1. Vehicle emission standards refer to regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot emitted from vehicle exhaust. 2. The purpose of vehicle emission standards is to prevent environmental pollution caused by exhaust from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.

Last year, I wanted to check the emission standard of my used car (commonly referred to as 'Guo Ji' in China), as I heard that vehicles from different years have varying emission standards, which can affect road access and annual inspections. I started by checking the vehicle's nameplate, usually located on the door frame or under the hood, where there's a label indicating 'Guo IV' or 'Guo V.' If the label was unclear, I referred to the information on the vehicle registration certificate, which also includes details about the emission standard. If that didn’t work, I directly entered the Vehicle Identification Number (VIN) on the Ministry of Ecology and Environment’s website or mobile app for a free query—super convenient, sometimes even displaying the environmental grade certificate. A quick tip: if none of these methods yield results, don’t worry—just drive to a 4S shop or repair shop. Technicians there have professional tools to scan and confirm it, usually costing just a few dozen yuan. After checking a few times, I realized it’s better to figure it out early, especially since areas with lower emission standards might impose driving restrictions, and you can also proactively maintain the exhaust system.

What are the effects of long-term battery depletion in a car?

The effects of long-term battery depletion in a car include: 1. It will affect the battery's lifespan, and frequent depletion will shorten its usage time; 2. It may prevent the car from starting, making the vehicle unusable, and other electrical devices in the car may also fail to function properly; 3. During startup, it may cause data loss in the vehicle's control modules, leading to operational failures, such as the loss of anti-theft system information; 4. It may cause the starter motor to overheat, reducing its lifespan; 5. After the vehicle starts, the generator will continuously operate under heavy load, which may damage the generator over time.

How Long Does a Car Battery Typically Last?

Car batteries typically last between 3 to 5 years. The battery is a crucial component in a vehicle, as the car cannot operate properly without it. When the engine is not running, the battery supplies power to all the vehicle's electronic devices and is also responsible for starting the engine. While the alternator is running, it generates electricity, which recharges the battery and powers the electronic devices. However, with repeated charging and discharging cycles, the battery's performance gradually declines. During charging or discharging, ions within the battery move through the electrolyte, and some of these ions undergo chemical reactions with the electrolyte as they move.

What is the normal battery voltage?

Normal battery voltage ranges between 11.8V and 12.8V, while the voltage after starting the engine is between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Both excessively high and low battery voltages can have certain impacts, so it is advisable to regularly check the battery's condition. If the battery voltage drops below 10.8V, it should be charged promptly. Precautions for using the battery: 1. Keep the battery clean and dry, ensuring that the vent holes are unobstructed; 2. Do not use the starter continuously, with each use not exceeding 5 seconds, and allow a rest period of 10 to 15 seconds between two starts; 3. A battery with sufficient electrolyte should not be left in a state of insufficient charge for a long time and should be charged regularly, otherwise it may lead to scrapping.

How early can a vehicle inspection be conducted?

It can be processed up to 90 days in advance. Below is more information about vehicle inspection: 1. The specific time for vehicle inspection (vehicle testing) is based on the month of the inspection validity period. For example, if the expiration date for annual inspection printed on the duplicate of the driving license is July 2015, the owner can participate in the annual motor vehicle inspection from "May 1, 2015, to July 31, 2015". 2. Vehicle inspection, also known as annual motor vehicle inspection, is a mandatory test for every vehicle that has obtained an official license plate and driving license. It involves examining the vehicle according to the safety technical conditions for motor vehicle operation, aiming to "eliminate potential vehicle safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents."
