    • CUSTOMER CARE

      A:

      Generally sound occurs in a car by Spark Plug due to when part of the air-fuel mixture in the combustion chamber away from the spark plug is spontaneously ignited by the pressure from a flame front originating from the spark plug. The two colliding flame fronts contribute to the “knocking” sound. Knock occurs more frequently when using low octane fuel. Low octane fuel has a low resistance to knock (low resistance to ignition). Knock is related to ignition timing. (Knock is sometimes referred to as “Spark-knock”.). Retarding the ignition timing will reduce knock.
