| 초록 |
The technical importance of the turbocharger for improving gasoline engine efficiency and improving reactivity is increasing. In particular, the reduction of friction loss and evaluation of the turbine operating characteristic are important in improving the turbocharger’s performance. This measurement can be confirmed by a runaway experiment using a zero power disc. However, the experimental methods and application limitations are not presented in detail. Therefore, in this study, the runaway test method and the application limit are presented based on the measurement results on the turbocharger for passenger cars. |
