Optimum Control of Variable Geometry Turbine in Automotive Turbocharged Diesel Engines
Published October 17, 1994 by Society of Automotive Engineers of China in China
An experimental and theoretical study on optimum control of automotive Diesel engines has been started by the authors. The first stage of the investigation is focused on the improvement of turbocharger control, with special reference to variable geometry (VG) regulating systems. An instrumented engine test bed was set up at the University of Genoa and a 1.9 l turbocharged Di Diesel engine fitted with a variable geometry turbine was installed. Besides a theoretical matching model was developed to be used as a support in the study of new strategies to control the VG turbocharger. The paper presents the first experimental and theoretical results: engine and turbocharger performance measured with the original VG turbine control device are analyzed and discussed. The matching procedure was also tested by comparing calculation results with experimental data.
