    摘要： An engine with a turbo supercharger (1) has a first turbo (3A) and a second turbo (3B). A first upstream section (55U) that is a scroll starting point of a first scroll passage (55) of the first turbo (3A) and a second upstream section (53U) that is the scroll starting point of a second scroll passage (53) of the second turbo (3B) are disposed, respectively, on a side that is farther than a first turbine shaft (37) and a side that is farther than a second turbine shaft (38) with respect to an engine body (10). The first and second scroll passages (55, 53) are passages scrolled so that downstream sides of the first and second upstream sections (55U, 53U) face a side closer to the engine body (10) than the respective turbine shafts (38, 37) are, and scroll in opposite directions to each other. Consequently, a first turbine (33T) and a second turbine (35T) rotate in opposite directions to each other.

    摘要： Provided is an actuator 30 for actuating a movable part of a turbocharger 20 that includes a turbine housing 21 for accommodating a turbine driven by exhaust, and a compressor housing 22 for accommodating a compressor which is disposed on the same axis as the turbine and which pressure-feeds intake air, wherein the actuator 30 is provided with a rod 31 of which one end side is coupled by a link to the movable part, a case 33 having a bearing part that slidably and axially supports the other end side of the rod 31, a boot 34 which covers the sliding part of the rod 31 and the bearing part and of which at least part of the outer peripheral surface faces the outer peripheral surface of the turbine housing 21, and a thermal shield member 40 disposed between the turbine housing 21 and the boot 34.

    摘要： The invention relates to a pneumatic adjusting drive (16) for a wastegate valve (9) of a turbine (2) of an exhaust gas turbocharger (1) of an internal combustion engine having a housing (17), in which a separating element (18) separating a control pressure chamber (20) from a reference pressure chamber (21) is adjustably arranged, with a drive rod (28) for the drive coupling to the wastegate valve (9), which is connected to the separating element (18) in a fixed manner, and with a resetting spring device (29) arranged in the housing (17), which drives the separating element (18) with a preload force (30) in the direction of the control pressure chamber (20). A simplified handling is obtained with a force adjusting device (32) for changing the preload force (30) with the drive rod (28) not coupled to the wastegate valve (9).
