Abstract:
Die Erfindung betrifft ein Verfahren zum Betreiben eines Verbrennungsmotors mit folgenden Schritten: - Bereitstellen eines Brennstoffs (2) - Umwandlung eines Teil des Brennstoffs in einen angepassten Brennstoff (7) während des Betriebs des Verbrennungsmotors, wobei der angepasste Brennstoff (7) eine niedrigere Zündwilligkeit hat als der unveränderte Brennstoff (2) - Zufuhr des angepassten Brennstoffs (7) zu einem Zylinder (1) des Verbrennungsmotors - Zufuhr von unverändertem Brennstoff (2) zum Zylinder (1) des Verbrennungsmotors, insbesondere zum Auslösen der Zündung, wobei die Zufuhr von unverändertem Brennstoff (7) zum Zylinder während des Kompressionstrakts des angepassten Brennstoffs im Zylinder erfolgt, - Antreiben eines Kolbens (9) des Verbrennungsmotors durch die Zündung. Die Erfindung betrifft ferner einen entsprechenden Verbrennungsmotor und eine Steuereinheit.
Abstract:
Eine Drei-Wege-Katalysatoreinheit für Verbrennungsmotoren, die einen ersten Grundkörper aufweist, durch den rußpartikelfreies Abgas hindurchgeleitet wird, und mit einer in dem ersten Grundkörper vorgesehenen Bearbeitungseinrichtung, in der im Abgas enthaltene Stickoxide zu Stickstoff reduziert und un- oder teilverbrannte Bestandteile eines Brennstoffs regeneriert werden, ist gekennzeichnet durch einen zweiten Grundkörper, der zur Vermeidung von Partikeln im Abgas stromaufwärts des ersten Grundkörpers in einer Treibstoffleitung des Verbrennungsmotors angeordnet ist.
Abstract:
Catalyst compositions and methods for use of such catalyst composition in the exhaust gas recycle stream of an internal combustion engine for reforming of a methane-containing fuel are provided. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and a method of operating an internal combustion engine for methane combustion are also described.
Abstract:
Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and and a method of operating an internal combustion engine using methane-assisted combustion are also described.
Abstract:
A Catalyzator makes the explosion/expansion more complete and more efficient and therefore the engine becomes more efficient and economical. We will place a Catalyzator/Catalyst mechanism in the external explosion/expansion chamber in an engine where there is a use of external explosion/expansion chamber The patent is for using one or more catalyzators/catalysts inside an external explosion/expansion chamber, the sort and size of the catalyzator/catalyst will vary depending on different factors, such as temperature and pressure inside the chamber, furthermore depending on the fuel which is used inside the chamber.
Abstract:
An internal combustion engine 10 includes a combustion chamber 12. The chamber includes a body 18 that is movable in the chamber to vary the chamber volume and contains a catalyst 50. First valving 24 is operable to admit an intake gas into the chamber and second valving 30 connected with an aqueous fluid supply system 32 is operable to admit an aqueous fluid and a steam reforming fuel into the chamber. A controller 48 is configured to cause the second valving 30 to admit a aqueous fluid and an amount of the steam reforming fuel into the chamber and when a predetermined condition exists in the chamber during compression of the intake gas to absorb heat generated by the compression of the intake gas in the presence of the catalyst to promote a steam reformation process to separate hydrogen from the steam reforming fuel or said aqueous fluid.
Abstract:
Fuel efficiency in a combustion engine is increased by treating the fuel in a reaction chamber prior to delivering the fuel into the combustion chamber of the engine. The method includes the step of entraining a stream of exhaust gas to travel upstream through the reactor chamber in a first flow pattern. The method also includes the step of entraining a stream of fuel to travel downstream through the reactor chamber in a second flow pattern, where at least one of the first and second flow patterns comprises a structured turbulent flow.
