Question

What is the relationship between the octane number and the knock rating for a gasoline engine? A. The higher the octane number, the lower the knock rating. B. The lower the octane number, the lower the knock rating C. The higher the octane number, the higher the knock rating D. The lower the octane number, the higher the knock rating.

Answer 1

The correct answer is C. The higher the octane number, the higher the knock rating.The octane number is a measure of the anti-knock properties of gasoline. It indicates the ability of the fuel to resist pre-ignition or knocking during combustion in an internal combustion engine. The knock rating, on the other hand, is a measure of the tendency of the fuel to cause knocking or pre-ignition.A higher octane number means that the gasoline has a higher resistance to knocking, which translates to a lower knock rating. Conversely, a lower octane number indicates a higher susceptibility to knocking, resulting in a higher knock rating.Therefore, the correct relationship between the octane number and the knock rating for a gasoline engine is that the higher the octane number, the lower the knock rating.
