What are the differences between 92via and 92vi?

[DiDaniel]

92via gasoline refers to ethanol gasoline, which is a new alternative energy source formed by blending fuel ethanol processed from grains and various plant fibers with regular gasoline in a certain proportion. The 'vi' in 92vi stands for 'Ⅵ', indicating that it is gasoline compliant with the China VI emission standard. It is mandatory to sell China VI standard fuel before selling China VI standard vehicles, and it is absolutely unacceptable to use China V standard fuel in China VI vehicles. Gasoline Anti-Knock Performance: The ability of automotive gasoline to resist knocking and ensure normal combustion. After the mixture of automotive gasoline and air is ignited by the spark plug in the combustion chamber of the gasoline engine, the flame should spread evenly and stably throughout the entire combustion chamber. Gasoline Stability: The ability of gasoline to resist oxidation under certain external conditions, referred to as stability. During storage, gasoline oxidizes to form gums and corrosive oxides. The deposition of gums in the vehicle's fuel supply system can reduce fuel delivery and decrease engine power.
