In 2015, a novel control concept for the partial admission of a turbocharger turbine named MEDUSA (Multiple Exhaust Duct with Source Adjustment) was presented at the Stuttgart International Symposium. The basic idea of this control concept is to divide the turbine inlet into several sectors along the circumference and to control the admission of the different sectors individually. This partial admission approach works similar to a Variable Nozzle Turbine (VNT) control system and allows to increase the turbine inlet pressure at low engine mass flows by closing turbine inlet segments and thus restricting the effective flow area. As a consequence higher turbocharger power output at low engine load conditions can be achieved.
