The invention relates to an engine combustion optimization and exhaust purification device and method based on reformed gases, in particular to the fields of recycling and utilization of waste heat in engine exhaust, hydrogen production technology based on fuel reforming, mixed combustion of reformed gases of an engine, exhaust treatment and the like. The device is divided into four parts: a, an exhaust treatment module; b, a reformed fuel supply module; c, a reformed gas storage and supply module; and d, an electronic control module; and the reformed gases including H2 and CO can be preparedvia reforming reaction of reforming fuels in the presence of a catalyst and at a certain temperature. The reformed gases and gasoline can be filled into an engine cylinder for mixed combustion. The composition of fuels of an internal combustion engine can be improved in an early period, the combustion in the cylinder can be optimized, the engine exhaust can be treated in a late period, and the purpose of exhaust purificat
