Performance of Automotive Turbochargers: Experimental Studies Developed at the University of Genoa

All dates for this event occur in the past.

 

Topic: Turbocharging has become a key technology not only to improve automotive engine performance, but also to reduce fuel consumption and exhaust emissions. However, a successful application of exhaust turbocharging to automotive engines must overcome various difficulties, related both to the specific operating environment (exhaust gas temperature level) and to engine performance, focusing on low-end torque and transient response.

The 1D models, generally adopted to develop ICE-TC matching calculations, require several information on turbine and compressor behavior. Different drawbacks have to be overcome in order to improve calculation results. Dedicated investigations on the turbocharging system are therefore necessary in order to get a better understanding of its performance. Several aspects need to further investigation, such as compressor and turbine performance under unsteady flow conditions, optimum control of turbocharger regulating devices, compressor surge detection, heat transfer phenomena, etc.

The Internal Combustion Engines Group operating at the University of Genoa has been engaged for more than 30 years in experimental studies on automotive turbochargers. This seminar presents some results of investigations developed at the University of Genoa on a dedicated test rig, which allows performing tests on intake and exhaust automotive engine components both under steady and unsteady flow conditions.   

Presenter: Massimo Capobianco received his MS Degree in Mechanical Engineering with honors at the University of Genoa in 1977. In 1978, he joined the University of Genoa where he is now Full Professor of Fluid Machines at the Department of Mechanical, Energy, Management and Transportation Engineering (DIME).

Professor Capobianco is the director of the Fluid Machines Energy Systems and Transportation Division (MASET) of DIME and the coordinator of the DIME Teaching Committee.

He has been the responsible for the University of Genoa of several research projects funded by the European Union and the Italian Government in the field of internal combustion engines.  

Professor Capobianco is the coordinator of the Internal Combustion Engines Group (ICEG) established at the University of Genoa. He is the author of more than 130 technical papers published in journals or presented at national and international conferences. Professor Capobianco conducts research in the area of internal combustion engines and fluid machines, with emphasis on turbocharging, experimental techniques in fluid machines, use of biofuels in ICE, road vehicles exhaust emissions in real driving conditions.

Professor Capobianco is the teacher of the following courses at the University of Genoa: Fluid Machinery, Internal Combustion Engines, Energy Systems and Environmental Impact.
