型エンジンの制御装置。 In a control device for an exhaust gas turbocharged engine that inputs the engine speed and engine load and controls the nozzle vane opening of the exhaust gas turbocharger via a controller and an actuator, a boost pressure sensor and an engine Compare the deviation between the set boost pressure determined by mapping depending on the operating condition and the detected boost pressure detected by the boost pressure sensor with its allowable deviation,
When the above deviation is below the above allowable deviation, the nozzle vane opening is held as is, and when the above deviation is above the above allowable deviation, the above vane is opened when the detected boost pressure is below the set boost pressure. and a controller that controls the nozzle vane in the opening direction when the detected boost pressure is equal to or higher than the set boost pressure, and fully closes the nozzle vane when the exhaust brake is activated. Control device for exhaust gas turbocharged engine.
