Abstract: A vehicle is a series hybrid vehicle that drives drive wheels using a travel motor by utilizing power of a power generation motor, which generates power by being driven by motive power of an internal combustion engine provided with a turbo charger. A method for controlling the vehicle includes executing a fuel cut of the internal combustion engine when excess power is greater than at least power that can be inputted in the system and the internal combustion engine is being supercharged.

Abstract: Provided is a variable-throat exhaust turbocharger in which a nozzle assembly including a nozzle mount and nozzle vanes has a firm support structure without affection by a thermal deformation of a turbine casing and an external force exerted to the turbine casing, and a scroll portion is formed in a substantially opened configuration so that the nozzle assembly can be simply formed in order to reduce the number of mold cores for a scroll during casting of the turbine casing, thereby it is possible to enhance the productivity of the turbine casing.
