Abstract
The gas engine with a gas fuel reforming device thermally decomposes CH.sub.4, a major component of natural gas, into a reformed fuel of CO and H.sub.2 to increase the heat produced and thereby reduce the CO.sub.2 content in the exhaust gas and prevent the formation of NO.sub.x. The gas engine mixes CH.sub.4 with CO.sub.2 and sends the gas mixture to the catalyst reactor installed in the exhaust passage where the gas mixture is thermally decomposed into a reformed fuel by using the thermal energy of the exhaust gas. CO.sub.2 is extracted from the exhaust gas by the CO.sub.2 supply device which in turn sends the CO.sub.2 to the catalyst reactor. The CO.sub.2 supply device comprises a CO.sub.2 dissolving device that accommodates a solution to dissolve CO.sub.2 of low-temperature exhaust gas and a CO.sub.2 delivery device installed in the exhaust passage through which high-temperature exhaust gas flows and adapted to release CO.sub.2 from the solution supplied from the CO.sub.2 dissolving device. The CO.sub.2 supply device can be formed of a CO.sub.2 separation membrane that separates CO.sub.2 from the exhaust gas.
