A turbocharger device includes a turbine and a compressor coaxially connected to each other. The turbine is equipped to an exhaust system of an engine. The compressor is equipped to an intake air system of the engine. An EGR device recirculates a part of exhaust gas as EGR gas from a downstream of the turbine to an upstream of the compressor. The EGR device includes an EGR cooler, which is to cool EGR gas, and an EGR valve unit, which is to control a flow of EGR gas according to an opening of an EGR valve. The EGR cooler, the EGR valve unit, and the turbocharger device are screwed to a common bracket and are positioned relative to each other. |
