Kernstück
der Anordnung gemäß
Die
Wasserstoffherstellung erfolgt hier durch Elektrolyse von destilliertem
Wasser, das im Kathoden- und Anodenraum durch den von der Zusatzlichtmaschine
Die
Reaktionsräume des Elektrolyseurs
Bei
einem in dem Gasspeicher
Die
Zufuhr des Wasserstoff-Sauerstoff-Gasgemisches in den Ansaugtrakt
Mit der oben beschriebenen Anordnung wird der Verbrennungsmotor ausschließlich bei sehr hoher Motorleistung, das heißt bei dem extrem hohen Kraftstoffverbrauch beim Anfahren und Beschleunigen eines Kraftfahrzeugs und gesteuert über den sich im Ansaugtrakt ändernden, einen bestimmten Wert unterschreitenden Unterdruck, zusätzlich mit einem Wasserstoff-Sauerstoff-Gemisch versorgt. Dadurch wird der thermische Wirkungsgrad des Verbrennungsmotors erhöht und es sind erhebliche Kraftstoffeinsparungen in der Größenordnung von bis zu 30% möglich. Zudem kann die Verbrennungstemperatur um bis zu 15% gesenkt und somit der Schadstoffgehalt im Abgasdeutlich verringert werden. Die Anordnung ist einfach und kostengünstig und – insbesondere wegen des geringen Wasser- und Gasspeichervolumens – platzsparend ausgebildet und auch zur Nachrüstung von bereits in Betrieb befindlichen Motoren geeignet. Durch die Verwendung von destilliertem Wasser sowie durch den infolge der intensiven Kühlung des Elektrolyseprozesses sowie der in den Wassertank integrierten Wasserabscheidung ist der Anteil korrosiv wirkender Bestandteile im Wasserstoff-Sauerstoff-Gemisch und damit die Korrosionsgefahr im Motor und in der Abgasanlage gegenüber den aus dem Stand der Technik bekannten Vorrichtungen deutlich reduziert.With the arrangement described above, the engine is only at very high engine power, that is, in the extremely high fuel consumption when starting and accelerating a motor vehicle and controlled by the intake manifold changing, a certain value below negative pressure, in addition to a hydrogen-oxygen mixture provided. As a result, the thermal efficiency of the internal combustion engine is increased and significant fuel savings on the order of up to 30% are possible. In addition, the combustion temperature can be reduced by up to 15%, thus significantly reducing the pollutant content in the exhaust gas. The arrangement is simple and inexpensive and, in particular because of the low water and gas storage volume - space-saving design and also suitable for retrofitting already in operation engines. The use of distilled water as well as due to the intensive cooling of the electrolysis process and the integrated water separation in the water tank, the proportion of corrosive constituents in the hydrogen-oxygen mixture and thus the risk of corrosion in the engine and in the exhaust system compared to those of the prior Technique known devices significantly reduced.
