Abstract
To compute the matching performance of diesel engine with variable geometry turbocharger (VGT), the formerly used program is improved through adjustment of turbine mass flow rate and efficiency characteristics. The calculation result is applied to forecast the performance of J6110Z diesel engine with rotary-vaned VGT70, and to guide the improvement of engine fuel supply. The computed engine performance curve coincides with the experiment result well: the low-speed torque, fuel economy, exhaust temperature and boost pressure of the VGT engine are all improved.
