Abstract: PURPOSE:To prevent variations in torque and abrasion in a transmission section, by connecting a supercharger to a high load passage in an engine provided with high and low load intake-air valves, and as well by disconnecting the drive power transmission of the supercharger only when the high load valve is opened during the period from the bottom dead center of a suction stroke to the intermediate of the subsequent compression stroke. CONSTITUTION:In a combustion chamber 13 there are provided valves 14A, 14B which are opened upon high and low load operations, and the high load valve 14A is opened during the period from the bottom dead center of a suction stroke to the intermediary of the consequent compression stroke. Further, there is provided a flow control valve 19 upstream of the valve 14A. Upon high load operation, when the valve 14A is opened and closed, the supercharger is driven, but the initiation of the drive and as well the stop of the drive in particular upon high load operation are carried out only upon opening of the high load intake-air valve. With this arrangement torque variations due to variations in intake-air flow may be prevented so that a drive resistance caused by the pressure of the intake-air pipe is reduced upon initiation of the drive of the supercharger so that the transmission section of the supercharger may be prevented from being worn.
