摘要： An exhaust gas recirculation system for an internal combustion engine comprises an exhaust driven turbocharger having a low pressure turbine outlet in fluid communication with an exhaust gas conduit. The turbocharger also includes a low pressure compressor intake and a high pressure compressor outlet in communication with an intake air conduit. An exhaust gas recirculation conduit fluidly communicates with the exhaust gas conduit to divert a portion of exhaust gas to a low pressure exhaust gas recirculation branch extending between the exhaust gas recirculation conduit and an engine intake system for delivery of exhaust gas thereto. A high pressure exhaust gas recirculation branch extends between the exhaust gas recirculation conduit and the compressor intake and delivers exhaust gas to the compressor for mixing with a compressed intake charge for delivery to the intake system.

摘要： An intake system for an internal combustion engine comprises an exhaust driven turbocharger configured to deliver compressed intake charge, comprising exhaust gas from the exhaust system and ambient air, through an intake charge conduit and to cylinders of the internal combustion engine. An intake charge cooler is in fluid communication with the intake charge conduit. A cooling system, independent of the cooling system for the internal combustion engine, is in fluid communication with the intake charge cooler through a cooling system conduit. A coolant pump delivers a low temperature cooling medium from the cooling system to and through the intake charge cooler for the transfer of heat from the compressed intake charge thereto. A low temperature cooler receives the heated cooling medium through the cooling system conduit for the transfer of heat therefrom.

摘要： An engine control system for controlling engine operation in activated and deactivated modes in a displacement on demand (DOD) engine includes an impulse charging device that is disposed upstream of an intake port of a cylinder of the DOD engine and that is operable to regulate air flow into the cylinder. A first module initiates impulse charging to regulate air flow into the cylinder when a desired engine torque output nears a first threshold engine torque output during engine operation in the deactivated mode.

摘要： An intake port pressure control system comprises an intake passage leading to a cylinder in an engine, and a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid back-flow in the reverse direction. A bypass port is located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and intake valve. The intake port pressure control system further comprises a control valve having an outlet passage, a secondary passage, and an actuator enabling communication between the outlet passage and secondary passage. The actuator further enables active adjustment of the flow area of the flowpath between the secondary passage and outlet passage throughout a range of engine operating conditions. The outlet passage is connected to the bypass port, and the secondary passage is connected to a secondary air source. The control valve enables a controlled air flow therein between the secondary air source and the trapped volume when the intake valve is closed.
