Dual Butterfly Control Valve and Method of Use

Номер: US20120042955A1
Автор: John D. Gierszewski
Принадлежит: Caterpillar Inc

A valve for a plenum or pipe is disclosed. The valve includes a large butterfly valve element pivotally supported in the plenum by at least one rod. The large butterfly valve element includes an opening for accommodating a small butterfly valve element. The small butterfly valve element is coupled to the rod by a shaft. The shaft includes a recess that accommodates the small butterfly valve element but which includes a clearance between the small butterfly valve element and the shaft to permit limited rotation of the shaft before the small butterfly valve element engages at least one wall of the recess of the shaft. Thus, the combination of the shaft and the small butterfly valve element provide limited flow through the plenum. Further rotation of the shaft, however, results in rotation of the large butterfly valve element to provide greater flow through the plenum.

The invention relates to a fluid valve, in particular for the exhaust gas from a motor vehicle engine, comprising a body ( 30 ) defining a main duct ( 31 ) and an auxiliary duct ( 32 ) for the flow of fluid, which auxiliary duct opens into the main duct ( 31 ). The valve also comprises: a flap ( 1 ) that can move between a closed position, preventing communication between the two ducts ( 31, 32 ), and an open position, allowing communication between said ducts ( 31, 32 ); and a gasket ( 2 ) against which the flap ( 1 ) bears when in the closed position. In addition, the above-mentioned body comprises a housing ( 37 ) for a motor for actuating the flap ( 1 ). According to the invention, the body ( 30 ) is configured to define a fluid lamina ( 38 ) between the gasket ( 2 ) and the housing ( 37 ).

Exhaust gas throttle valve

Номер: US20130199176A1
Автор: John Zagone, Luis Carlos Cattani, Martin R. Zielke, Michael D. Bartkowicz
Принадлежит: International Engine Intellectual Property Co LLC

A method for driving exhaust gas recirculation comprising the steps of restricting exhaust gas flow into the turbine inlet to create backpressure in the exhaust system under low engine operating conditions, and providing an unrestricted exhaust gas flow to the turbine under normal engine operating conditions. Restriction of exhaust gas flow is accomplished through the use of an exhaust gas throttle valve disposed upstream of the turbine inlet. The valves can be adjustable knife edge flap valves or D-shaped valves situated in each passageway of a divided exhaust manifold, which are closed to varying degrees to generate desired levels of backpressure while allowing exhaust gas to pass though open regions of the partially obstructed flow pathway to reach the engine turbocharger. This allows the turbine to continue to spin, while at the same time exhaust gas back pressure upstream of the turbocharger is used to drive exhaust gas recirculation.

An arm portion is integrally formed with a housing. The arm portion protrudes from the housing in such a manner as not to be in contact with a passage-forming portion and a passage-side fastening portion. The arm portion has corner portions and a drive-side fastening portion. After a heat of EGR gas is transferred to the drive-side fastening portion, the heat is transferred to the housing through the corner portions. The arm portion elongates a heat transfer pass from the EGR gas to the driving portion to increase a resistance of heat transfer. Further, the arm portion increases a heat radiation surface area to increase a heat radiation quantity. The EGR apparatus 1 can restrict a heat transfer from the EGR gas to the driving portion.

An exhaust gas recirculation (EGR) system for an internal combustion engine having dedicated EGR and operating at a net stoichiometric air-fuel ratio. In such engines, one or more cylinders is operable as a dedicated EGR cylinder, such that all of the exhaust produced by the dedicated EGR cylinder(s) may be directed back to the intake manifold. Because the engine's exhaust is net stoichiometric, its exhaust aftertreatment system has a three-way catalyst. An EGR loop is configured to recirculate EGR from the dedicated EGR cylinder(s) to the engine's intake manifold. A diversion line, modulated with a valve, connects the EGR loop to the exhaust aftertreatment system, thereby allowing adjustment of the relative amounts of EGR to be recirculated and to be provided to the exhaust system.
