Abstract:
A gas engine with a gas fuel reforming device, comprising:a fuel tank containing a natural gas fuel having CH.sub.4 as a major component;an exhaust passage to discharge exhaust gas from combustion chambers;a catalyst reactor installed in the exhaust passage to thermally decompose a gas mixture of CH.sub.4 and CO.sub.2 into a reformed fuel of CO and H.sub.2 by using thermal energy of the exhaust gas;a gas fuel supply device to supply the natural gas fuel from the fuel tank to the catalyst reactor;a CO.sub.2 supply device to supply to the catalyst reactor CO.sub.2 separated from the exhaust gas by a CO.sub.2 separator; anda reformed fuel supply device to supply the reformed fuel to the combustion chambers;wherein the combustion chambers are formed in a heat insulating structure of a ceramic member.
