Abstract: The present invention relates to a device and a method for adjusting the air supply amount of an engine having a supercharger and, more particularly, to a device and a method for adjusting the air supply amount of an engine having a supercharger, in which the operation of the supercharger is controlled to a level at which the amount of air required to suit a driver-requested torque is supplied so that the driver-requested torque can be satisfied with precision. In other words, according to the device and the method for adjusting the air supply amount of an engine having a supercharger of the present invention, the supercharger is operated for the supercharging of intake air when the request amount of air is equal to or greater than the standard natural intake air amount after the calculation of the required amount of air based on the driver-requested torque. In contrast, when the required amount of air is equal to or smaller than the standard natural intake air amount, the supercharger is not operated and control such as the opening of a bypass valve for natural air intake is performed at the same time. Accordingly, pressure loss can be prevented during the operation of the supercharger and flow path resistance to the intake can be minimized during the non-operation of the supercharger. [Reference numerals] (AA) Driver-requested torque; (BB) Fully open a bypass valve; (CC,EE,JJ) No; (DD) Required amount of air > Standard intake amount of natural air; (FF) Operate a supercharger in an idle manner; (GG,LL) Yes; (HH) Operate the supercharger; (II) Required amount of air
