Es wird ein Schiffsantriebssystem offenbart mit einem Verbrennungsmotor zum Antreiben eines Schiffs, wobei der Verbrennungsmotor eine Verbrennungskammer zum Verbrennen eines fossilen Kraftstoffs umfasst, mit einer Elektrolysekammer zum Erzeugen von Wasserstoffgas und Sauerstoffgas, und mit einer Unterdruckpumpe zum Absaugen des Wasserstoffgases und des Sauerstoffgases aus der Elektrolysekammer. Das Schiffsantriebssystem weist zudem einen Vergasungstank auf, in welchem flüchtige organische Verbindungen, insbesondere Methanol oder Ethanol, vergast werden, sowie eine Versorgungsleitung zum Zuführen eines Gasgemisches zur Verbrennungskammer, wobei das Gasgemisch vergaste organische Verbindungen sowie zumindest einen Teil des Wasserstoffgases und des Sauerstoffgases umfasst. Zudem wird ein entsprechendes Verfahren zum Betreiben eines Schiffsantriebssystems offenbart.
摘要:
A portable, on-demand hydrogen generation system (l) is provided for producing hydrogen and injecting the hydrogen as a fuel supplement into the air intake of internal combustion engines (32), more particularly to vehicles (31). Hydrogen and oxygen is produced with a fuel cell (5) at low temperatures and pressure from water in a supply tank (6). The hydrogen and oxygen is passed back through the supply tank (6) for distribution and water preservation. The gases are kept separate by a divider (17) in the tank (6) and the water level in the tank (6). In the case of gasoline engines (32), the hydrogen is directed to the air intake (38) of the engine (32) while the oxygen is vented to the atmosphere. The device (1) is optionally powered by the vehicle battery (33), a stand alone battery, waste heat of the internal combustion engine (32) or solar energy. The system (1) utilizes a vacuum switch (35) or other engine sensor that permits power to the device (1) and therefore hydrogen production only when the engine (32) is in operation. Therefore, as the hydrogen is produced it is immediately consumed by the engine (32). No hydrogen is stored on, in or around the vehicle (31).
摘要:
The working gas circulation engine includes a combustion chamber (11) to which plural kinds of reactant gas and working gas having a higher specific heat ratio than air are supplied and in which the working gas is expandable corresponding to reaction of the plural kinds of reactant gas, a circulation route (20) capable of circulating gas containing the working gas from an exhaust side to an intake side of the combustion chamber (11) and resupplying to the combustion chamber (11) and provided with a removing device (40) to remove a product generated with the reaction from the circulating gas, a supplying device (30) capable of supplying the plural kinds of reactant gas to the combustion chamber (11) or the circulation route (20), a pressure detecting device (62) capable of detecting pressure in the circulation route (20), and a control unit (50) that controls supply amount of at least one kind of the reactant gas to be supplied from the supplying device (30) based on the pressure in the circulation route (20) detected by the pressure detecting device (62), and performs pressure control to adjust the pressure in the circulation route (20). Accordingly, excessive pressure variation in the circulation route can be suppressed.
摘要:
A process for operating a marine engine (1) in combination with a catalytic partial oxidation reformer (2) and, optionally, an exhaust gas aftertreater (3) , wherein: (a) a mixture of a first fuel and air, is introduced in the combustion chamber of the engine (1) ; (b) exhaust gas is discharged from the engine and optionally partly recirculated to the combustion chamber of the engine (1) ; (c) a second fuel and oxygen and/or steam are supplied to the catalytic partial oxidation reformer (2) to produce synthesis gas, wherein the second fuel comprises Fischer-Tropsch derived fuel; (d) at least part of the synthesis gas is supplied to: (i) the exhaust gas aftertreater (3) ; (ii) the combustion chamber of the engine (1) ; or to both.
