Abstract
A turbocharger control apparatus has an exhaust turbine including an exhaust gas introducing port having a variable nozzle which can vary a passage area of the port by adjusting its opening degree, an engine load detection device which detects a load of an internal combustion engine, an idling state detection device which detects an idling state of the engine, and a control device which adjusts the opening degree of the nozzle in a region equal to or greater than a predetermined opening degree when the load detection device detects the engine load, and which adjusts the opening degree of the nozzle in a region smaller than the predetermined opening degree when the load detection device detects the non-engine load and detects that the internal engine is in the idling state. A control method of a turbocharger with a variable nozzle, has a step which detects an idling state and a load state of an internal combustion engine, and a step which adjusts an opening degree of the nozzle in a region equal to or greater than a predetermined opening degree when the load state of the engine is detected, and which adjust the opening degree of the nozzle in a region smaller than the predetermined opening degree when the idling state and the non-load state of the engine is detected.
