内燃機関の制御装置、内燃機関、及び内燃機関の制御方法
Document Type and Number:
Japanese Patent JP6657633
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine, an internal combustion engine, and a control method of an internal combustion engine, capable of improving control of the internal combustion engine by suppressing occurrence of problems caused by error expansion of a detection value of an excess air factor sensor, saturation and response lag in a control system of the internal combustion engine controlling the internal combustion engine by using a detection value of the excess air factor sensor disposed in an exhaust passage.SOLUTION: A control device 30 of an internal combustion engine calculates a calculation value λc of an excess air factor of an exhaust gas G on the basis of an operation state of the internal combustion engine 10, and determines a weighted average value λm of the calculation value λc of the calculated excess air factor of the exhaust gas G and a detection value λd of the excess air factor sensor 24 as a use value λ of the excess air factor used in controlling the internal combustion engine.SELECTED DRAWING: Figure 1
