The simplest and most direct method is to look at the vehicle's identification plate. The vehicle identification plate is a label that indicates the basic characteristics of the vehicle, including the manufacturer's brand. You can also visit professional inquiry websites to check. You can search for the keyword "motor vehicle environmental protection" on Baidu. Another way is to find the vehicle's factory certificate, provided it is a new car. Check the vehicle's factory certificate for the information. Alternatively, you can personally take the vehicle's registration certificate to the environmental protection window at the vehicle management office or the local motor vehicle pollution management center. The staff there will assist in checking the information.

I just helped my dad check the displacement of his used car a couple of days ago. The most straightforward method is to look at the vehicle license. On the third page of the license under the 'Brand and Model' section, for example, it might say 'Changan SC6489B5'—the displacement is usually hidden within that alphanumeric combination. A 1.5L displacement typically shows up as numbers like 1468CC. If you don't have the document handy, open the front door and crouch down to check the vehicle identification plate on the B-pillar; it will have the engine displacement printed on it, though the font is small so look carefully. By the way, when washing the car, avoid using a high-pressure water jet directly on the plate, as it can easily wash away the lettering.

Checking the engine displacement isn't that complicated. I usually refer to the vehicle conformity certificate, where the 'Engine Model and Displacement' section clearly states it. If you can't find the certificate, here's a trick: start the car and listen to the engine sound – smaller displacement engines have more frequent 'puttering' sounds at idle, while larger displacement engines produce deeper, more resonant noises. The most reliable method is to check the VIN (Vehicle Identification Number), that 17-digit code at the bottom left of the windshield. Decode it using a mobile app, and the 8th letter indicates the displacement grade. A mechanic once taught me that you can also estimate by checking the engine oil capacity – generally, a 4L oil bottle corresponds to a 2.0L engine displacement.

Want to know the displacement? Just check the most prominent label in the engine bay! It's usually stuck on the engine cover or firewall metal plate, with black background and white letters indicating '1598mL' for a 1.6L engine. If the label is covered by oil stains, use your phone to check the official model parameters on the manufacturer's website by entering the model code on the rear of the car. Remember one time when car shopping, the salesperson pointed at the '280TSI' badge on the rear and claimed it was a 2.0T, but checking the label revealed only 1.4L - so don't just trust the badges. It gets even more complicated with new energy vehicles, where plug-in hybrids require adding the electric motor power to the engine displacement for total output.

What Type of Fuel Should a China VI Standard Vehicle Use?

China VI models only refer to vehicles whose emissions of various pollutants meet the China VI limit requirements, and the type of fuel used is irrelevant. Simply follow the vehicle's manual for fuel recommendations. Below is relevant information about China VI standards: 1. Concept: The term 'China VI' means that a vehicle's emission standards meet the requirements specified in the sixth phase of the national emission standards, commonly abbreviated as China VI emissions. This standard began to be implemented gradually from the end of 2019. China's vehicle emission standards are modeled after European emission standards, with the latest being the China VI emission standard. The sixth phase imposes stricter regulations, significantly reducing the levels of various harmful gases. 2. Emission Standards: These regulations specify the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. The purpose of setting vehicle emission standards is to curb the production of these harmful gases, encouraging automobile manufacturers to improve emission standards and reduce the generation of harmful gases.

Can the green vehicle registration book be reissued if lost?

The green vehicle registration book can be reissued if lost. You can apply for a reissue at the vehicle management office where the vehicle registration certificate was originally processed. Definition: The vehicle management office is a direct agency under the public security system, primarily responsible for handling motor vehicle registration, modification, transfer, mortgage, and cancellation. It is generally available only at the county level or higher administrative regions. Job Supervision: Each motor vehicle and driver's license service position in the vehicle management office has the obligation to supervise the work of the previous position. If any issues are found, such as questionable procedures handed over from the previous position, violations in processing, or non-standard filling of certificates and forms, or failure to sign and stamp as required, they should be reported to the supervisory position. The supervisory position should immediately investigate and handle the issue and keep a record of the handling.

What are the classification levels for water submersion?

"Water-damaged vehicles" are classified into three levels based on the extent of water submersion: 1. "Water-soaked vehicles," where water exceeds the tire level. 2. "Partially submerged vehicles," where water surpasses the engine oil dipstick. 3. The most severe case is called "fully submerged vehicles," where water exceeds the roof level. Below is relevant information: Operational lifespan of water-damaged vehicles: Considering the vehicle's design lifespan and market conditions, many owners of water-damaged vehicles can still drive them for about four years, while some repaired water-damaged vehicles may last up to five years. Therefore, even after repairs, as long as the vehicle's technical condition is restored, it can typically operate normally for four to five years. Hazards of water-damaged vehicles: Water-submerged vehicles are prone to electronic system short circuits, posing safety risks such as spontaneous combustion. For instance, critical systems like ABS anti-lock braking, ESP stability control, and ECU engine control may fail to function when needed, leading to potentially disastrous consequences. Additionally, many external repair shops fail to meet quality standards, making it nearly impossible to fully restore the vehicle to 100% of its technical requirements. The lifespan of certain components is significantly reduced, which is one of the reasons why water-damaged vehicles are generally not recommended.
