CONTROL APPARATUS OF VARIABLE NOZZLE-TYPE TURBOCHARGER, AND CONTROL METHOD THEREOF |
摘要 |
After an engine stopping operation, nozzle vanes (10) provided in a variable nozzle-type turbocharger (4) are displaced toward a closed side for the purpose of reference position determination of the vanes (10) for the next engine operation. The displacement of the nozzle vanes ( 10) is performed after it is determined that the engine has stopped rotating. Therefore, the control apparatus prevents an undesired event where the flow speed of exhaust gas blown onto a turbine wheel (6) becomes excessively great, so that the overspeed rotation of the turbocharger (4) occurs and a malfunction results. |
