A method and an apparatus for sensing an air flow into a cylinder of an internal combustion engine are arranged to determine a number of revolutions of the engine, determine a pressure of an intake pipe of the engine, and calculate an air flow Qc into a cylinder of the engine, based on the number of revolutions and the pressure of the intake pipe by the linear expression of Qc= alpha P+ beta , in which alpha is a coefficient indicating a gradient of a linear expression and defined according to the number of revolutions, beta is a coefficient indicating an offset value and defined according to the number of revolutions, and P is a pressure of the intake pipe. The method and the apparatus for controlling fuel of the internal combustion engine operate to generate a fuel flow signal according to the air flow into the cylinder determined by the above method and feed fuel to the internal combustion engine at a flow rate corresponding to a fuel flow signal.
