Abstract

A dedicated exhaust gas recirculation (“D-EGR”) system of an internal combustion engine can include an exhaust recirculation passage, and a rotary valve. The recirculation passage can be coupled for fluid communication with an outlet of a D-EGR combustion chamber. The rotary valve can have a housing and a rotor. The housing can have a valve inlet coupled to the recirculation passage to receive exhaust gases from the recirculation passage, and a valve outlet coupled to an intake passage of the ICE to deliver exhaust gases from the rotary valve to the intake passage. The rotor can be disposed within the housing and rotatable relative to the housing. The rotor and housing can define a plurality of valve chambers.
