Abstract:
A method and apparatus for reducing the percentage of nitrogen dioxide and nitrogen monoxide in an exhaust gas stream of an internal combustion engine, comprising the steps of injecting a hydrocarbon compound and optionally hydrogen into the exhaust gas stream; passing the exhaust gas through a first catalyst for selective reduction of a portion of the nitrogen oxides to nitrogen, ammonia, and N-containing species; passing the exhaust gas through a second catalyst for selective reduction of a portion of the nitrogen oxides with ammonia to molecular nitrogen; sensing ammonia concentration in the exhaust gas stream after passage through either or both of the first and second catalysts; and controlling by a controller in a feedback loop the injecting to an amount of hydrocarbon that will produce a predetermined concentration of ammonia and nitrogen oxides at the sensor that will lead to high NOx conversion.
Abstract:
A fuel injector for an internal combustion engine operated by a liquefied gas fuel includes an isolation valve (60) that interrupts the fuel supply passage (2) supplying pressurised fuel, such as liquefied dimethyl ether, to the injector nozzle (22). A further isolation valve (60') may be included in a fuel outlet passage (50) of the injector. The isolation valves (60,60') are maintained in an open position by the fuel pressure in the injector when the pressure reaches a predetermined level, such as occurs when the engine is switched on, but close when the engine is switched off and the fuelpressure decays. The injector nozzle may therefore be isolated from the remainder of the fuel system when the engine is not running. To control injection timing, the injector may also include a statically leakless valve (102) in fluid communication with afluid outlet line (130) upstream of the further isolation valve (60') and isolated from the fuel supply passage, thereby reducing the risk of stem leakage.

Abstract:
Die vorliegende Erfindung betrifft eine Gehäuseanordnung für einen Gasgenerator, welcher ein inneres Gehäuse zur Aufnahme einer Treibladung aufweist. Ferner umfasst die Gehäuseanordnung eine das innere Gehäuse umgebende Filtereinheit sowie ein das innere Gehäuse und die Filtereinheit umgebendes zylindrisches Gehäuse. Das innere Gehäuse und das äußere Gehäuse weisen jeweils eine Ausströmöffnung auf, welche derart versetzt zueinander angeordnet sind, dass die Gehäuseanordnung von den bei der Verbrennung der Treibladung frei werdenden Gase in Umfangsrichtung oder in axialer Richtung durchströmbar ist. In dem Ringspalt, in dem die Filtereinheit zwischen dem inneren Gehäuse und dem äußeren Gehäuse angeordnet ist, ist ein sich in axialer Richtung der Gehäuseanordnung erstreckendes Strömungshindernis vorgesehen und derart angeordnet, dass die Filtereinheit von den aus dem inneren Gehäuse ausströmenden Gasen nur in einer Umfangsrichtung durchströmbar ist.

Abstract:
A fuel injector (1) for an internal combustion engine, the fuel injector (1) being of a type with an open-ended nozzle body (3) adjoining an injector body (21). The interface (57) between the nozzle body (21) and the injector body (21) is flat, to simplify manufacture, and they are aligned relative to each other using a compression element (10) which is typically a sleeve that extends around them. The compression element (10) also acts to apply a pre-compression to at least one of the bodies (3, 21) to enable the fuel injector to operate at higher fuel pressures than would otherwise be possible.
