Most Upvoted Answer
Consider the following statements regarding knock rating of SI engine ...
Explanation:
The knock rating of SI engine fuels is determined using the octane number scale. The octane number represents the ability of a fuel to resist knocking or detonation in a spark-ignition engine. The higher the octane number, the better the knock resistance of the fuel.
Statement 1: Iso-octane is assigned a rating of zero octane number.
This statement is incorrect. Iso-octane is the reference fuel with excellent knock resistance, and it is assigned a rating of hundred octane number. It is used as a benchmark fuel for comparing the knock resistance of other fuels.
Statement 2: Normal heptane is assigned a rating of hundred octane number.
This statement is incorrect. Normal heptane is a fuel with poor knock resistance, and it is assigned a rating of zero octane number. It is used as a reference fuel for comparing the knock resistance of other fuels.
Statement 3: Iso-octane is assigned a rating of hundred octane number.
This statement is correct. Iso-octane is assigned a rating of hundred octane number. It has excellent knock resistance and is used as a reference fuel on the octane number scale.
Statement 4: Normal heptane is assigned a rating of zero octane number.
This statement is correct. Normal heptane is assigned a rating of zero octane number. It has poor knock resistance and is used as a reference fuel on the octane number scale.
Therefore, the correct statements are 3 and 4.
