Deposits in the combustion chamber, improper timing or too low an octane fuel are all causes of engine ‘knock’. Combustion chamber deposits can also result in after-run or continued combustion of gasoline after the engine is shut down. Periodic tune-up of gasoline spark-ignition engines will assure proper timing of spark plug firing and prevent this cause of engine ‘knock’. Engine deposits can alter the effective compression ratio of an engine as well as be a an unwanted source of ignition. Such deposits can cause pre-ignition and detonation. Pre-ignition is ignition of the gasoline/air mixture before the spark plug ignites this mixture and results in ‘knock’. Detonation can also be result from use of too low an octane fuel for an engine.
The use of Bardahl Octane Booster increases gasoline octane and brings about a controlled, more uniform gasoline combustion, reducing knock from pre-ignition and detonation. Bardahl Octane Booster’s action also inhibits after-run due to combustion chamber deposits.
Do not add more than prescribed, this may have an adverse effect.
