123568150 | Having exhaust gas mixed with a constituent before entry into intake manifold | 8 |
20090101123 | MULTIPLE HEIGHT FLUID MIXER AND METHOD OF USE - A mixer assembly ( | 04-23-2009 |
20110120432 | Variable Venturi System and Method for Engine - Systems and methods for an engine are described. In one example, a system may include a variable venturi coupled in an intake of the engine; an exhaust gas recirculation system having an exhaust gas recirculation flow path, the exhaust gas recirculation flow path coupled to the variable venturi; and a vacuum-utilizing device or system coupled to the variable venturi. In another example, a method may include coordinating adjustment of an exhaust gas recirculation valve coupled to the exhaust gas recirculation system, a fuel vapor purging valve coupled to the fuel vapor purging system, and the variable venturi in response to operating conditions. | 05-26-2011 |
20110168143 | Dual Throttle for Improved Tip-Out Stability in Boosted Engine System - A method for providing intake air to an engine in a vehicle includes forming a mixture of fresh air and treated exhaust, and compressing the mixture upstream of a first throttle valve coupled to an intake manifold of the engine. The method further includes, during a higher engine-load condition, admitting the mixture to the intake manifold via the first throttle valve, and, during a lower engine-load condition, admitting fresh air to the intake manifold via a second throttle valve. | 07-14-2011 |
20120325185 | CONNECTION BOX WITH CHARGING FLUID SUPPLY ARRANGEMENT FOR AN INTERNAL COMBUSTION ENGINE - In a connection box for direct connection to a charging fluid duct of a charging fluid supply designed for intermixing a charge air and an exhaust gas to form a charging fluid, comprising a housing with a charge air connecting space including at least a connection for a charge air guide arrangement, and at least one mixing channel in communication with the charge air connecting space via a connection for supplying charge air to the mixing channel and the mixing channel including a supply side exhaust gas connection for an exhaust gas recirculation and a charging fluid-side mixing channel connection for the charging fluid duct, the connection is arranged at a first front side of the housing, and the mixing channel extends along a longitudinal side of the housing from the first front side to a second front side of the housing opposite the first front side. | 12-27-2012 |
20130047967 | THREE-WAY VALVE WITH TOP END-STOP ON THE AIR PATHWAY - Three-way valve with two flaps comprising single control means ( | 02-28-2013 |
20130047968 | THREE-WAY VALVE WITH RETURN END-STOP ON THE AIR PATHWAY - Three-way valve with two flaps comprising common control means ( | 02-28-2013 |
20140158099 | System and Method for Improved Emissions Control - A system and method for improving exhaust gas recirculation performance is provided to induce improved exhaust gas recirculation flow during engine operating transients, including transients in which exhaust gas flow conditions are unfavorable. The apparatus includes an exhaust line including a mechatronic exhaust brake valve, an intake system including a PBS compressed air injection system, an exhaust gas recirculation passage between the exhaust and intake lines, and a controller which coordinates operation of the PBS and MEB. The controller is programmed to command the MEB to close for a period before the compressed air injection is initiated so as to build exhaust line backpressure pressure and maintain a desired pressure differential across the EGR passage so that recirculated exhaust gas flow continues to enter the intake during to PBS injection event to suppress formation of undesired excess NO | 06-12-2014 |
20140373819 | MIXER FOR PULSED EGR - A mixer for pulsed exhaust gas recirculation (EGR) includes a fresh intake air conduit having an inlet opening configured to be placed into fluid communication with a fresh intake air source, an EGR pocket having an upstream opening in fluid communication with an upstream air source and a downstream opening in fluid communication with the fresh intake air conduit, and an EGR conduit configured to introduce pulsed EGR into the EGR pocket. | 12-25-2014 |
