Claims

[Scope of utility model registration request]

A first turbocharger turbine that operates when the exhaust gas flow rate is low and a second turbocharger turbine that operates as the exhaust gas flow rate increases are interposed in parallel in a branch exhaust passageway that branches off the engine exhaust passageway. In the twin turbocharger device provided in the second turbocharger, a flow rate control valve controls a flow rate of exhaust gas supplied to each turbine between a turbine outlet of the second turbocharger and a confluence point of the branch exhaust passage according to exhaust pressure. A twin turbo charger device characterized by being provided with.
