摘要: A fully-integrated flow-control module which fits within an externally-threaded filler neck of a DBF tank, said flow -control module comprising: an adapter cap having internal threads that engage the externally-threaded filler neck of the DEB tank; a breather cap having a central fluid flow path, said breather cap equipped with a breather assembly, said breather assembly providing both a normally closed spring-loaded poppet that admits air into the DEB tank as it is emptied, and a spring-loaded breather piston that allows air to escape the DEB tank as it is filled. A receiver fitting coupled to an upper end of the breather cap, said receiver fitting being couplable to a dry-break DEB filler nozzle. A main valve body coupled to a lower end of the breather cap; a spring-biased valve piston installed within the main valve body so that it can slide both upwardly and downwardly therein, slidable movement of said valve piston being controlled by fluid pressure beneath the piston crown. Fluid pressure being controlled by fluid flow through a bleed path that begins through a bleed aperture in a center of the piston crown. Said valve piston operating to open and close a fill port through which fluid enters the DEB tank. A bleed/float body coupled to a lower end of the main valve body, said bleed/float body incorporating a majority of the bleed path. A connector beam to which both the control rod and the bleed valve poppet are rigidly secured.

摘要: Die Erfindung betrifft ein Kraftfahrzeug mit einem mit kohlenstofffreiem Kraftstoff, wie z.B. Wasserstoff oder Ammoniak, betriebenen Verbrennungsmotor mit daran angeschlossenem Abgassystem (1), welches einen zumindest ersten Stickoxidreduktionskatalysator (2), der vorzugsweise Vanadium, aufweist. Erfindungsgemäß weist das Abgassystem (1) ferner einen Wärmetauscher (3) auf, der zur Energierückgewinnung dienen kann, wobei vom Verbrennungsmotor abgegebenes Abgas vor einer Zufuhr zum Stickoxidreduktionskatalysator (2) mit einem einstellbaren Anteil durch den Wärmetauscher (3) geleitet werden kann. Es können auch zwei Stickoxidreduktionskatalysatoren hintereinander angeordnet werden, wobei das Reduktionsmittel der Kraftstoff sein kann. Das erfindungsgemäße Betriebsverfahren lehrt, dass der Anteil des durch den Wärmetauscher (3) geleiteten Abgases in Verbindung mit einem Betrieb des Wärmetauschers (3) und/oder einer Energierückgewinnungseinrichtung (6) so gewählt wird, dass eine Temperatur des ersten Stickoxidreduktionskatalysators (2) zumindest überwiegend unterhalb einer vorgebbaren oberen Temperaturgrenze gehalten wird

摘要: An apparatus for reducing emissions that has a combustion turbine that feeds exhaust into a heat recovery steam generator (or HRSG) casing in which is positioned an emission reduction system featuring, in gas flow sequence, a first reducing reductant injector (RRI1), as in an ammonia injection grid, for providing reducing reductant, preferably ammonia, into turbine exhaust travelling within the HRSG, followed by a first SCR reactor positioned downstream of the first RRI1, followed by one of either (i) a turbulence generator (TG) as in a static mixer, or (ii) a second RRI2 as in a second ammonia injection grid, o (iii) an RRI2 with integrated TG supported on injectors of RRI2, then followed by a second SCR reactor. The emission reduction system preferably is free of a separate body oxidation catalyst or a separate body ammonia slip catalyst in an effort to utilize a limited volume within the HRSG. Methods of assembling and operating the ERS or T-H combination with ERS are also featured.

摘要: An injector (122) for a diesel exhaust fluid (DEF) delivery system (104) includes a first conduit (200) extending along a longitudinal direction (174); a second conduit (202) extending along the longitudinal direction (174) and disposed within the first conduit (200); a nozzle tip (158) having a side wall (416) and an end wall (418); and a shell (280) surrounding the first conduit (200) and being spaced apart from the first conduit (200) along a radial direction (160). The side wall (416) has a thickness (422) extending along the radial direction (160) from an external surface (180) of the nozzle tip (158) to an inner surface of the second conduit (202). The end wall (418) defines an outlet flow passage (470) therethrough, and the outlet flow passage (470) is in fluid communication with the first conduit (200) and the second conduit (202) via a chamber (404) defined by an internal surface of the nozzle tip (158).
