ーボチヤージヤ付内燃機関。 Two exhaust turbochargers with different capacities are provided, and an on-off valve is provided in the exhaust passage that independently guides the exhaust gas from the engine to the turbine of the larger-capacity turbocharger, and the on-off valve is opened depending on the operating state of the engine. In an internal combustion engine with an exhaust turbocharger equipped with a valve opening control means, an abnormality detection means detects an abnormality in a turbocharger on a smaller capacity side, and when an abnormality in a turbocharger on a smaller capacity side is detected by the abnormality detection means. An internal combustion engine with an exhaust turbocharger, comprising: abnormality valve opening control means for controlling the opening of the on-off valve in priority to the valve opening control means.
