What is the emission standard of the Boyue?

The emission standard of the Boyue is China VI. It is clearly indicated in the configuration and price section under the powertrain/chassis system on the official website of Geely Boyue. The Geely Boyue is equipped with an oxidative honeycomb ceramic. When exhaust gases pass through the oxidative honeycomb ceramic, carbon monoxide and hydrocarbons are further oxidized into carbon dioxide and water. More details are as follows: 1. Geely Boyue utilizes exhaust gas recirculation, fuel tank vapor recovery, and engine electronic control systems to reduce emission pollution. The catalytic converter has always been the most effective method for reducing harmful exhaust emissions. 2. In the chemical reaction of the catalytic converter, precious metal atoms produce various transition reactions, which lower the overall activation energy of the reaction, thereby increasing the probability of converting exhaust gases into generally harmless gases.
I've checked the information, and the emission standard of the Boyue depends on the specific model year. For example, when it was first launched in 2016, it was China 5. Later, some models of the 2018 version still remained China 5. By the 2020 facelift, the entire lineup was upgraded to China 6, and now the new cars on sale all meet the China 6b standard. China 6 is much stricter than China 5, with requirements for carbon monoxide and particulate matter in exhaust emissions being cut in half. This upgrade is good for the environment, but older car owners need to be aware: many big cities now ban China 5 cars from entering restricted zones. If you're planning to buy a used Boyue recently, make sure to check the emission standard on the green book, and it's best to test the exhaust data before transferring ownership.
Speaking of the emissions of the Boyue, as an owner of a three-year-old China 5 version, I have deep feelings about it. When I bought the car, China 5 vehicles could still drive freely, but now many urban core areas have imposed restrictions. The new China 6 version indeed has upgraded engine technology, and I heard it includes a GPF (Gasoline Particulate Filter), but some people have reported higher maintenance costs later on. The most frustrating part is the cross-province transfer process. My friend tried to transfer his China 5 car from Hebei to Shandong last year and got stuck—it had to be upgraded to China 6 before it could be registered. If you're buying a used car, I strongly recommend checking the vehicle conformity certificate or using the VIN to look up the environmental disclosure information.
The 2018 Boyue gradually transitioned to China VI standards, and now the entire lineup meets China VI-b. This upgrade was backed by major technological innovations: thickened three-way catalytic converters, fuel injection pressure increased to 350 bar, and EGR exhaust gas recirculation ratio adjusted to 25%. The exhaust treatment is much more refined than in older models. In fact, China VI-compliant vehicles require specific attention to engine oil—low-ash SP-grade oil is a must, otherwise the particulate filter can easily clog. Additionally, note that modifying the exhaust pipe on a China VI-b vehicle can trigger an OBD alarm. I've seen owners fined 2,000 yuan for aftermarket exhaust modifications.
