Abstract

An engine system including a power plant, an intake assist device connected to an air inlet of the power plant, and an expander connected to an exhaust outlet of the power plant is presented. A motor / generator is connected to power the expander to selectively provide power to and capture power from the expander. An expander controller is connected to control the motor / generator connection to the expander, and is configured to select between a passive mode, where exhaust passively moves through the expander, and an active mode, where the motor / generator powers the expander to actively draw exhaust from the exhaust manifold. In one example, the air intake and exhaust flows are controlled independently of the rotational speed of the power plant.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 62 / 116,666, filed February 16, 2015, which is hereby incorporated by reference in its entirety. [0003] government license [0004] This invention was made with government support under DE-EE0006844 awarded by the US Department of Energy. The government has certain rights in this invention. technical field [0005] This application relates to engine systems. More specifically, the present application provides systems and methods for engine intake and exhaust flow management. Background technique [0006] Turbocharged gasoline engines may experience knocking at low engine speeds when the turbocharger is not operating in the desired speed range. When the engine is still cold or warmed up, it can be difficult to overcome knock because the turbocharger does not receive the heat and mass flow needed to rev the engine. Induces back p...
