China VI emission standard for trucks was implemented on July 1, 2021. Below is relevant information about it: Introduction to China VI: The "China VI" standard is an upgrade from the "China V" standard, requiring carbon monoxide emissions and total hydrocarbons to be reduced by more than 50% from the original baseline. According to the plan, the "China VI" standard will be implemented in two phases: 6A and 6B. The first phase started on July 1, 2020, and the second phase will begin on July 1, 2023. The World's Strictest Standard: The China VI standard references both the Euro 6c standard for emission limits and the OBD and evaporative emission requirements of the North American EPA-Tier3 standard, hence it is also known as the "world's strictest" standard.

I've been driving trucks for over a decade and remember clearly that the China VI emission standards for trucks officially started on July 1, 2021. That summer, everyone was talking about it. At the time, my old China V truck could no longer be used to purchase new vehicles—I had to upgrade to a China VI model to get it registered. The vehicle prices shot up significantly, but the emissions during operation were much lower, with far less black smoke coming from the exhaust. Driving in the city felt much more reassuring. I’d advise drivers to pay attention to local regulations in advance—some key regions like Beijing and Hebei implemented the standards earlier. If you’re late in replacing your vehicle, it could be troublesome, as it might not pass inspections. Overall, the policy is good, but for small operators like us, the cost pressure is considerable.

Having been in the transportation industry for a long time, I heard that the China VI emission standards for trucks were fully implemented on July 1, 2021. Our company quickly replaced a batch of vehicles at that time. The new China VI-compliant trucks feel quieter and more efficient, with slightly lower fuel consumption. Actually, this standard is divided into China VIa and China VIb. In 2021, it started with the a phase, and now by 2023, the b phase has become even stricter. A reminder to everyone: always check the emission level when buying a vehicle, otherwise you might face registration issues and waste money. In the long run, meeting environmental standards also reduces the risk of fines.

As a newcomer to the industry, I confirmed last year that the China VI emission standards for trucks took effect on July 1, 2021. This policy requires new vehicles to meet the standards before they can be sold, while older China V vehicles depreciate rapidly. Therefore, it's crucial to carefully check the emission certification labels when purchasing a truck. Some regions implemented pilot programs ahead of schedule, and overall, this policy helps improve air quality.

From a personal car-buying perspective, after the implementation of the China VI emission standards on July 1, 2021, I focus closely on emission levels when selecting a new truck. Although new vehicles are slightly more expensive, they have lower emissions, ensuring smoother road access and contributing to reduced smog issues—which is great. By the way, this standard drives automakers to upgrade their technology, and it's also shaking up the used car market. My advice is to plan ahead to avoid any inconvenience.

How to Tell if the Car Body is Straight After Turning?

Methods to determine if the car body is straight after turning are as follows: 1. While driving on the road: The simplest way to judge whether the car body is straight is by using the center divider line or the edge line of the road. When driving, if the markings in both side mirrors are parallel to the car body, then the car body is straight; otherwise, minor adjustments are needed. 2. When parking: If there are no other cars nearby, observe through the rearview mirror whether the rear of the car is parallel to the road edge or the parking line. If there are cars nearby, check through the rearview mirror whether the distance to the adjacent car is equal at both ends. Equal distance means the car is straight; if the rear of the car is too close to the adjacent car or the front is too close, it indicates the car body is tilted. 3. Observing the front of the car: You can also observe the front of the car. When parking, if the front part of the car is perpendicular to the road edge, it means the car body is straight; otherwise, the car needs to be repositioned.

What Causes the Red Engine Oil Light?

Generally, when the engine oil light illuminates in a vehicle, it indicates a fault in the engine's lubrication system. The full name of the oil light is the engine oil pressure indicator. This indicator is used to show whether the oil pressure is normal; if the oil pressure is abnormal, it will light up. Similar to the engine self-check indicator, the oil pressure light also turns on when the vehicle starts. If the oil pressure is normal, it will subsequently turn off. However, if the oil pressure remains abnormal, the light will stay on. In such cases, further inspection of the vehicle is necessary to diagnose the issue. Common causes for the oil pressure light to illuminate include: 1. Insufficient oil level leading to inadequate oil pressure. The oil pump's output decreases, resulting in reduced oil pressure and the illumination of the oil pressure light. It is essential to check for any engine leaks or faults causing oil consumption. 2. A malfunction in the oil pressure sensor itself, causing the vehicle's computer to receive incorrect oil pressure data, thus triggering the oil pressure light. 3. Faults in the wiring harness of the oil pressure sensor, such as open circuits or short circuits, leading to the illumination of the oil pressure light.

What is the difference between a vehicle identification number and an engine number?

Vehicle identification numbers and engine numbers are not the same. The vehicle identification number (VIN), commonly referred to as the frame number, can be found in the vehicle information section of your vehicle registration certificate. The engine number, listed as Engine No. on the registration, is stamped on the engine block, while the VIN is stamped on the vehicle's frame. It typically consists of a combination of 7 to 8 digits and letters. In addition to the methods mentioned above, the engine number can also be located through the following four ways: The vehicle registration certificate contains the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will specify the engine number; The car purchase invoice will list the engine number; The vehicle purchase tax payment certificate will indicate the engine number. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's lineup, and multiple engines can share the same model. The engine number, however, is the production serial number of the engine. Each engine is assigned a unique engine number, and no two engines share the same number.
