PURPOSE: An anti-knocking device and method for controlling the same are provided to improve the operation reliability of an engine by directly injecting ethanol to an end gas section in the shape of a right circular cone. CONSTITUTION: An anti-knocking device comprises a cylinder(11), a piston(10), first and second injectors, and an ignition plug(24). The piston moves back and forth in the cylinder, and comprises a center axis. A combustion chamber(12) is formed between the cylinder and piston. The first injector is separately inserted from the center axis of the piston, and directly injects a main fuel including gasoline to the combustion chamber. The second injector is inserted into the center axis of the piston, and injects a sub fuel including ethanol to the combustion chamber. The ignition plug is closely placed to the second injector on an upper part of the cylinder. |
