Abstract:
To properly set a vane opening according to an exhaust flow rate, in a supercharger having a variable nozzle mechanism.SOLUTION: A control device performs control processing including a step (S100) of calculating a base value of a vane opening, a step (S102) of calculating a feedback amount of the vane opening, a step (S104) of calculating a sum of the base value and the feedback amount, a step (S106) of calculating an effective opening area, a step (S108) of setting a lower limit value of the vane opening, a step (S112) of performing the opening control using the sum of the base value and the feedback amount as a command value, when the sum of the base value and the feedback amount is the lower limit value or more (YES in S110), and a step (S114) of performing the opening control using the lower limit value of the vane opening as a command value, when the sum of the base value and the feedback amount is less than the lower limit value (NO in S110).SELECTED DRAWING: Figure 3
