The Effects of Turbocharger Design and Installation on Gasoline Vehicle Transient Response 821149

A series of tests were run on a turbocharged gasoline powered vehicle to determine means of improving vehicle transient response through turbocharger design and installation modifications. Turbine inlet temperature, turbocharger rotating inertia, turbine housing flow characteristics, and turbine outlet pipe restrictions were found to have the most important effects on vehicle response. Turbine inlet pipe length and crossectional area had a large effect on turbine inlet temperature but had no significant effects on response if turbine inlet temperature was held constant.
