Are 92 and E92 gasoline interchangeable?
1 Answers
92 and E92 gasoline can be used interchangeably, as they share the same anti-knock properties, volatility, oxidation stability, corrosion resistance, and environmental requirements. The differences between 92 and E92 gasoline: 92-octane gasoline is regular unleaded gasoline without any alcohol content, while E92 gasoline refers to ethanol-blended gasoline, which contains 10% alcohol. The designation method involves adding the letter 'E' before the original gasoline grade. In terms of pricing, E92 gasoline is generally cheaper. Benefits of using E92 gasoline in cars: Since gasoline combustion significantly contributes to environmental pollution, many cities have introduced ethanol-blended gasoline to replace traditional gasoline in order to protect the atmospheric environment. Ethanol gasoline also has excellent cleaning properties, as ethanol can help dissolve and clean impurities in the car's fuel tank or fuel lines. Drawbacks of using E92 gasoline: Ethanol has a high heat of vaporization, and its evaporation temperature under theoretical air-fuel ratio conditions is higher than that of conventional gasoline. This affects the formation of the air-fuel mixture and combustion speed, leading to reduced vehicle power, fuel economy, and cold-start performance, which negatively impacts acceleration.
