Meanwhile, the oxygen-containing component is added into the gasoline fuel to accelerate the combustion speed of the gasoline fuel, so that a cylinder can burst higher pressure and output higher torque. The manufacturer or the modified owner can adjust the ignition advance angle of the engine according to the high-octane fuel, so that the engine can exert higher combustion efficiency, and further the power output is improved.
