摘要: 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.

摘要: 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.

摘要: An internal combustion engine has a primary fuel circuit for producing a lean mixture of air and hydrocarbon fuel to be fed into a combustion chamber and a secondary fuel circuit which includes a secondary carburetor for producing a mixture of air and methanol at an air-methanol ratio of less than 2.0. The air-methanol mixture is fed into a reactor vessel having therein a catalyst bed which is heated to facilitate reaction between the components of the air-methanol mixture. By the reaction the air-methanol mixture is converted into a reformed gaseous mixture rich with hydrogen which is then mixed with an air-hydrocarbon fuel mixture to form a composite mixture to be supplied into the combustion chamber. The existence of hydrogen in the composite mixture assures reliable spark-ignition and stable combustion of the composite mixture which is of a very large air-fuel ratio as calculated in terms of air-gasoline ratio, to thereby reduce the emission of harmful components of engine exhaust gas and improve the fuel consumption.
