What are the benefits of 98 octane gasoline?
1 Answers
The following are the benefits of 98 octane gasoline: 1. Performance and environmental aspects: Higher anti-knock performance and power, reduced harmful substances in gasoline and exhaust pollution. 2. Economic aspects: Enables pursuit of higher engine power with smaller displacement, improving both power and fuel economy. The following is related information about 98 octane gasoline: 1. Introduction: 98 octane gasoline is gasoline whose octane rating is equivalent to a mixture of 98% isooctane and 2% n-heptane. Engines with high compression ratios should use high-octane gasoline. If a high-compression engine uses low-octane gasoline, it can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Compared to other grades of gasoline, 98 octane gasoline has strong anti-knock properties and high combustion value, providing more powerful performance. However, due to its high grade and price, it is mostly used by luxury cars and is often referred to as 'premium gasoline.' 2. Standards: The country has strict standards for automotive gasoline. It not only requires gasoline to have a certain octane rating (commonly known as the gasoline grade) but also imposes strict regulations on the content of various chemical components in gasoline. If the olefin content is too high, the gasoline cannot burn completely, producing a gummy substance that accumulates in the intake manifold and valve guide areas. When the engine is at normal operating temperature, there are no abnormal phenomena; however, when the engine is shut off and cooled for a period, these deposits can stick the valve in the valve guide. Starting the engine at this time can cause valve sticking.
