Abstract:
An engine with a turbo supercharger has a first turbo and a second turbo. A first upstream section that is a scroll starting point of a first scroll passage of the first turbo and a second upstream section that is the scroll starting point of a second scroll passage of the second turbo are disposed, respectively, on a side that is farther than a first turbine shaft and a side that is farther than a second turbine shaft with respect to an engine body. The first and second scroll passages are passages scrolled so that downstream sides of the first and second upstream sections face a side closer to the engine body than the respective turbine shafts are, and scroll in opposite directions to each other. Consequently, a first turbine and a second turbine rotate in opposite directions to each other.

Claim (Index 1):
An engine with a turbo supercharger comprising:\n an engine body; and a turbo supercharger disposed adjacent to the engine body, having an exhaust passage into which exhaust air is supplied from the engine body, and supercharging intake air admitted into the engine body, wherein the turbo supercharger includes a first turbo including a first turbine having a first turbine shaft, and a second turbo including a second turbine having a second turbine shaft, wherein the exhaust passage includes: an admission passage admitting the exhaust air from a side of the engine body; a first scroll passage having a first upstream section communicating with the admission passage and guiding the exhaust air toward the first turbine; and a second scroll passage having a second upstream section communicating with the admission passage and guiding the exhaust air toward the second turbine, wherein the first and second scroll passages are passages scrolled so that the first and second upstream sections are disposed, respectively, on a side that is farther than the first turbine shaft and a side that is farther than the second turbine shaft with respect to the engine body, and that downstream sides of the first and second upstream sections face a side closer to the engine body than the first and second turbine shafts are, wherein the first turbine rotates about the first turbine shaft in a predetermined first rotation direction, whereas the second turbine rotates about the second turbine shaft in a second rotation direction opposite the first rotation direction.
