A compressor (5) of a turbo supercharger (3) is located between an air flow meter (12) and a throttle valve (13). An EGR passage (21) is connected to an intake passage (10) at a joint (22) upstream of the compressor (5). The following relationship (1) is satisfied between an intake passage volume (V1) from the air flow meter (12) to the junction (22), an intake passage volume (V2) from the compressor (5) to the throttle valve (13) and a maximum boost pressure (Pb) under operating conditions in which the introduction of EGR gas is performed, in order to prevent a mixed gas of fresh air and EGR gas from flowing back to the air flow meter (12) even under the maximum boost pressure (Pb). V 1 > V 2 × ( P b - P 1 P 1 ) × ( P 1 P b ) κ - 1 κ ( 1 )
