Abstract: PURPOSE: A method for controlling the knocking of a dual fuel engine is provided for drivers to drive a car in an optimal situation by improving engine performance with control characteristics which are actively varied. CONSTITUTION: A method for controlling the knocking of a dual fuel engine comprises following steps. Whether or not the knocking occurs is detected(S10). The strength of the knocking is measured if the knocking occurs(S20). If the strength of the knocking is below a predetermined level, the knocking is controlled by the direction injection of sub fuel(S30). If the strength of the knocking is above the predetermined level, the knocking is controlled by delaying ignition timing(S40). The direct injection amount of the sub fuel is reduced(S50). The delayed ignition timing returns to a normal state(S60). [Reference numerals] (AA) Starting an engine; (BB) Delaying ignition timing; (CC,EE) Increasing the direct injection amount of sub fuel; (DD) Simultaneously reflecting ignition timing delay and fuel amount increase due to a target ignition timing suitable for engine operating conditions and a fuel amount(the amount of mixed gasoline and sub fuel)+knocking occurrence; (FF) Reflecting fuel amount increase due to a target ignition timing suitable for engine operating conditions and a fuel amount(the amount of mixed gasoline and sub fuel)+knocking occurrence; (S10) Knocking has occurred?; (S20) The intensity of the knocking is above a predetermined level?
