Document Type and Number:
Japanese Patent JP2022065013
Kind Code:
A
Abstract:
To provide an engine which favorably detects abnormality in flow rate control of a bypass flow passage on a supercharger.SOLUTION: An engine comprises: an exhaust bypass flow passage which connects an outlet of an exhaust manifold and an exhaust outlet of a supercharger and is provided with an exhaust bypass valve V3; and an intake bypass flow passage which connects an inlet of an intake manifold to an inlet of the supercharger and is provided with an intake bypass valve V2. An intake pressure sensor detects pressure of the intake manifold. A control device outputs a command value of an opening of either the exhaust bypass valve V3 or the intake bypass valve V2 so as to perform feedback control on the basis of detection values of an engine load and the intake pressure sensor.SELECTED DRAWING: Figure 8
