What is the China VI gasoline standard?

[DeDaniella]

China VI gasoline has the following characteristics: 1. Stricter olefin content limits: reduced from 24% to 18% in China VIa phase and 15% in VIb phase; 2. Stricter aromatic content limits: reduced from 40% to 35%; 3. Stricter benzene content limits: reduced from 1% to 0.8%, which is stricter than the EU standard of 1%; 4. Stricter gasoline distillation 50% evaporation temperature limits: reduced from 120°C to 110°C. Additional information: Using China VI fuel not only reduces vehicle emissions but also decreases the formation of engine carbon deposits and reduces engine wear due to lower levels of combustion waste and impurities, thereby extending engine lifespan to some extent. Ethanol gasoline, on the other hand, is a new alternative fuel formed by mixing fuel ethanol with regular gasoline in a certain proportion.
