| Abstract: |
| Problems of power declining, fuel consumption increasing, and efficiency of turbocharger dropping, over temperature and over-speed of turbine of diesel engine were analyzed. Various regulated turbocharging systems were taken into consideration to improve the diesel engine and turbocharger running at high altitude. Variable geometry turbocharging (VGT), classical two-stage regulated turbocharging (TST), compound turbocharging (C2T) and two-stage regulated turbocharging based on VGT (R2T) were introduced, including structure principle and application of the systems at plateau. At last, the development trend of self-adaptive turbocharging technologies were put forward from five aspects: structural arrangement of turbocharging system, intelligent optimization algorithms, control theories, multi-system cooperative control, optimizing inner flow field of turbocharger, and combined with the characteristics of diesel engine working at varying operations and altitudes.. |
