Abstract
The disclosure provides a turbo-charging apparatus for a vehicle engine, which includes a first and second turbocharger, an inter-turbine passage connecting a discharging port of a first turbocharger turbine with an introducing port of a second turbocharger turbine, a bypass passage connecting an introducing passage of the first turbocharger turbine with the inter-turbine passage, and a control valve for opening and closing the bypass passage. The inter-turbine passage extends substantially straight from the discharging port of the first turbocharger turbine toward the second turbocharger when viewed from a direction parallel to turbine shafts of the first and second turbochargers, which are arranged substantially parallel to each other, so that the inter-turbine passage connects with an outer circumferential part of the second turbocharger turbine so as to extend in a direction tangent to an outer circumference direction of the second turbocharger turbine.
