20110162360 | EGR MIXER FOR HIGH-BOOST ENGINE SYSTEMS - An EGR mixer comprises an upstream conduit section having a contracting flow area in a direction of air flow through the mixer, a downstream conduit section having an expanding flow area in the direction of air flow through the mixer, a slot formed in the downstream conduit section for admitting exhaust to the air flow, and an abrupt flow-expanding ridge disposed between the upstream and downstream conduit sections. With the EGR mixer configured in this manner, recirculated exhaust may be effectively homogenized into an intake air flow with reduced drag. | 07-07-2011 |
20110265473 | EXHAUST GAS RECIRCULATION SYSTEM - An exhaust gas recirculation (EGR) system for a vehicle is provided. The EGR system includes a turbine fluidly coupled downstream of an exhaust manifold and an EGR conduit including a first port coupled to an exhaust passage directly downstream of the turbine, an axis of the first port arrange at a non-perpendicular angle with respect to the rotation axis of the turbine and a second port coupled to an intake system. | 11-03-2011 |
20130220289 | INTAKE SYSTEM WITH AN INTEGRATED CHARGE AIR COOLER - An intake assembly in an engine is provided. The intake assembly includes a compressor and a plenum in fluidic communication with the compressor, the plenum having an integrated charge air cooler including a coolant inlet and a coolant outlet in fluidic communication with a coolant passage and cooling plates extending into a plenum enclosure and coupled to the coolant passage. The intake assembly further includes a throttle body coupled to the plenum. | 08-29-2013 |
20140157774 | COMPRESSOR BYPASS TURBINE-GENERATOR - Embodiments for a turbine-generator position in a compressor bypass flow path are presented. In one example, a method for an engine having a compressor comprises generating energy via a turbine-generator positioned in a bypass flow path of the compressor. In this way, the energy of the recirculated intake air may be recovered by the turbine-generator. | 06-12-2014 |
20140352668 | SYSTEMS AND METHODS FOR HEATING A PRE-COMPRESSOR DUCT TO REDUCE CONDENSATE FORMATION - Methods and systems are provided for providing auxiliary heat to a pre-compressor duct wall to reduce condensate formation. A coolant valve may control the delivery of heated engine coolant to the pre-compressor duct wall. The coolant valve may be adjusted based on condensate formation at the pre-compressor duct wall. | 12-04-2014 |
20150176478 | SYSTEM AND METHODS FOR ENGINE AIR PATH CONDENSATION MANAGEMENT - A system and methods for routing condensate collected in a heat exchanger reservoir to either an air intake system or a position in the engine exhaust based on the type of contaminate in the condensate and operating parameters of the engine or the catalyst are described. In one particular example, condensate is routed to a first position along the engine air intake system in a first mode of operation, and a second position upstream of the catalyst along the engine exhaust in a second mode of operation, and a third position downstream of the catalyst along the engine exhaust in a third mode of operation. When substantially no contaminates are detected, the condensate may be routed into the engine exhaust upstream of the catalyst in order to cool the catalyst. | 06-25-2015 |
20150176480 | SYSTEM AND METHODS FOR ENGINE AIR PATH CONDENSATION MANAGEMENT - A system and methods for routing condensate collected in a heat exchanger reservoir to either a combustion chamber of an engine or a position in the engine exhaust based on the type of contaminate in the condensate and operating parameters of the engine or the catalyst are described. In one particular example, the method includes accumulating a portion of compressed air in an accumulator, and when an engine output is below a predetermined amount, coupling a part of the accumulated air with the condensate through a passage into the combustion chamber. Thereby, the methods described may be used to distribute condensate formed in the heat exchanger even at low engine loads. | 06-25-2015 |
20160097332 | THROTTLE BYPASS TURBINE WITH EXHAUST GAS RECIRCULATION - Various systems and methods are provided for controlling the temperature of outlet gasses from a throttle bypass turbine. In one embodiment, a method of operating a throttle bypass turbine comprises controlling a temperature of outlet gas flowing out of the turbine by routing the outlet gas through an exhaust gas recirculation heat exchanger positioned in an exhaust gas recirculation passage, the turbine coupled to an intake passage. | 04-07-2016 |
