    • A system for converting a rich air-fuel mixture into a reformed gaseous mixture containing hydrogen forms a part of an intake system of an internal combustion engine. The system includes an intake passage divided by a dividing wall into a first and a second sub-passages for receiving relatively lean and rich parts of the rich air-fuel mixture, respectively. The first sub-passage has a sparking plug for igniting and burning the relatively lean part of the mixture to produce heat which is transferred by the dividing wall and, as occasion demands, by a heat exchanger to the relatively rich part of the mixture flowing through the second sub-passage in order that a part of the fuel is converted into reformed gaseous mixture and the remainder of the fuel is effectively vaporized. Thereafter the rich air-fuel mixture is directed to a catalyst bed disposed downstream of the first and the second sub-passages and subjected to the fuel reformation operation, wherein the fully vaporized fuel is completely converted into reformed gaseous mixture. The sub-passages and the catalyst bed are disposed in the system upstream of a throttle valve, whereby the system is protected from variation in the vacuum produced in the intake system of the engine and thus is reliably operative to produce the reformed gaseous mixture.
    • 用于将富空燃混合物转化为含氢气的重整气体混合物的系统形成内燃机的进气系统的一部分。 该系统包括由分隔壁分成进入第一和第二子通道的进气通道,用于分别接收富空燃料混合物的相对稀薄和富含部分。 第一子通道具有用于点燃和燃烧混合物的较薄部分的火花塞,以产生由分隔壁转移的热量,并且根据需要,通过热交换器流向流过的混合物的较浓的部分 第二子通道,以使燃料的一部分转化为重整气体混合物,并且剩余的燃料被有效地蒸发。 此后,将富空燃混合物引导到设置在第一和第二子通道下游的催化剂床,并进行燃料重整操作,其中完全蒸发的燃料完全转化为重整气体混合物。 副通道和催化剂床设置在节气门上游的系统中,从而保护系统不受发动机进气系统中产生的真空变化,从而可靠地操作以产生重整气体混合物。

    • An internal combustion engine is provided with an EGR system and a system for catalytic coversion of a rich air-fuel mixture into a reformed combustible gaseous mixture rich with free hydrogen. During a low or medium engine load engine operation, the engine is operated solely by an air-gasoline mixture and with an exhaust gas recirculation at a rate not higher than a predetermined first EGR rate. During a high engine load engine operation, the reformed combustible gaseous mixture is added to the air-gasoline mixture supply and simultaneously the exhaust gas recirculation is increased to a rate higher than the predetermined first EGR rate to increase the engine output, improve the engine drivability and improve the consumption of the reformed combustible gaseous mixture. The intake manifold vacuum is electrically detected to determine the load on the engine and to control valves associated with the EGR system and reformed gas supply system.
    • 内燃机设置有EGR系统和用于将富空燃混合物催化转化成富含游离氢的重整可燃气体混合物的系统。 在低或中等发动机负载发动机运行期间,发动机仅由空气 - 汽油混合物和排气再循环以不高于预定的第一EGR率的速率运行。 在高发动机负载发动机运转期间,将重整的可燃气体混合物加入到空气 - 汽油混合物供应中,同时排气再循环增加到比预定的第一EGR率高的速率以增加发动机的输出,提高发动机的运转性能 并改善可燃气体混合物的消耗。 电气检测进气歧管真空以确定发动机上的负载并控制与EGR系统和重整气体供应系统相关联的阀。

    • A fuel reforming system for an internal combustion engine comprises a fuel circuit connected at its downstream end to the engine and including a carburetor for producing a rich air-fuel mixture and a fuel reforming reactor vessel containing a catalyst for facilitating a catalytic reformation of the mixture into a reformed gaseous mixture rich with free hydrogen. The carburetor is provided with a primary air intake passage with a venturi into which air and fuel are fed to produce a rich air-fuel mixture. The carburetor is also provided with a secondary air intake passage bypassing the venturi and connected to the fuel circuit downstream of the venturi. A valve is provided on the carburetor to control the cross-sectional area of the secondary air intake passage in accordance with the temperature in the engine or the reactor vessel, by the carburetor is adjusted according to the engine or reactor vessel temperature.
