What do gasoline VIA and VIB mean?
1 Answers
China VI is divided into "China VIA" and "China VIB" based on different olefin content. Here is the relevant information: 1. China VIa: China VIa is essentially a transitional phase between "China V" and "China VI". China VIa will be implemented for gas-powered vehicles on July 1, 2019, for urban vehicles (city buses, sanitation trucks, postal vehicles, etc.) on July 1, 2020, and for all vehicles on July 1, 2021. 2. China VIb: China VIb is the true "China VI" emission standard. China VIb will be implemented for gas-powered vehicles on January 1, 2021, and fully implemented for all vehicles on July 1, 2023.
