  • Patent number: 10697358
    Abstract: An intake passage structure for a turbocharger-equipped engine (1) includes a supercharging passage (71) and an air relief passage (72) that are provided in a compressor case (72a). The air relief passage (72) has a first passage (73) and a second passage (74), each of which is in a non-linear shape. The first and second passages (73) and (74) each have an air outflow port (73a, 74a) formed through an inner wall surface of an upstream portion (71a) of the supercharging passage (71) upstream of a compressor (21). The air outflow ports (73a, 74a) are formed through different portions of the inner wall surface in a circumferential direction of the inner wall surface so as to overlap with each other in a direction along a central axis of the upstream portion (71a).
