| Zusammenfassung: | To provide a controller capable of suppressing damage to a supercharger.SOLUTION: A controller of a supercharger comprises a turbine arranged in an exhaust passage of an internal combustion engine, and a compressor arranged in an intake passage of the internal combustion engine and driven by the turbine. The controller has: a control unit that controls the turbine so that a boost pressure of the supercharger in the intake passage is equal to or lower than an allowable value; a first calculation unit that calculates an amount of decrease in compressor efficiency of the compressor; and a second calculation unit that calculates the allowable value from an intake volume of the intake passage in accordance with the amount of decrease.SELECTED DRAWING: Figure 4
【課題】 過給機の破損を抑制することができる制御装置を提供する。【解決手段】 制御装置は、内燃機関の排気路に配置されるタービンと、前記内燃機関の吸気路に配置され、前記タービンにより駆動されるコンプレッサとを備えた過給機の制御装置において、前記吸気路内の前記過給機の過給圧が許容値以下になるように前記タービンを制御する制御部と、前記コンプレッサのコンプレッサ効率の低下量を算出する第１算出部と、前記低下量に応じて、前記吸気路の吸気量から前記許容値を算出する第２算出部とを有する。【選択図】図４ |
