PROBLEM TO BE SOLVED: To provide a natural gas reforming internal combustion engine absorbing carbon dioxide contained in exhaust by carbon dioxide absorbent, recovering the carbon dioxide gas by heating the carbon dioxide absorbent, and using a substance formed by reacting the carbon dioxide with methane gas, or a major fuel, as the fuel. SOLUTION: A reformer 43 is disposed in an exhaust path of an engine 2, a carbon dioxide recovery device 27 is disposed in the downstream of the reformer 43, mixed gas between the carbon dioxide from the carbon dioxide recovery device 27 with the natural gas (methane gas) is introduced to the reformer 43 via a reforming gas heat exchanger 43a, and the reformed gas reformed by the reformer 43 is fed to the engine 2 via the reformed gas heat exchanger 43a. The carbon dioxide recovery device 27 comprises a vessel 27a filled with the carbon dioxide absorbent 67, a cooler 26 cooling the exhaust to be introduced to the vessel 27a, and a heater 43b heating the carbon dioxide to be introduced to the vessel 27a by the exhaust.
