雙渦輪增壓

Twin-turbo is a type of turbo layout in which two turbochargers are used to compress the intake air/fuel mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes.
