Title: Variable-speed supercharger for highly diluted internal combustion engines

Abstract

An engine control system includes an internal combustion engine including a plurality of cylinders. An intake manifold is connected to the internal combustion engine. An exhaust manifold is connected to the internal combustion engine. A supercharger is connected to an air intake passage and the intake manifold and includes a variable speed drive. A throttle valve is disposed in the air intake passage. An exhaust passage is in connection with the exhaust manifold. A passive selective catalytic reduction catalyst system is in communication with the exhaust passage. An exhaust gas recirculation passage is in communication with the exhaust passage and the air intake passage and includes an exhaust gas recirculation valve. A controller controls the variable speed drive of the supercharger and the throttle valve and the exhaust gas recirculation valve based upon engine conditions.
