摘要
Problem to be solved: to provide an exhaust gas nonequilibrium reforming system in an internal combustion engine capable of improving expected fuel consumption.Exhaust gas purifying catalyst provided in an exhaust passage of an internal combustion engineAn exhaust gas recirculation passage capable of recirculating exhaust gas from an upstream side of an exhaust gas purification catalyst to an intake passage of an internal combustion engineFuel injection means for reforming fuel for reforming fuel to exhaust recirculation passage andIt is provided in the exhaust recirculation passage.Carbon dioxide absorption releasing material for absorbing and releasing carbon dioxide in exhaust gas recirculation gas and reforming catalyst for producing hydrogen from the reforming fuelAn exhaust gas recirculation valve for adjusting the amount of exhaust gas recirculated to the intake passage in accordance with an operating condition of the internal combustion engine and an exhaust gas recirculation valveEquipped withIf the carbon dioxide storage rate is lowThe ratio of exhaust gas recirculation to the total gas content in the internal combustion engine is relatively high.Carbon dioxide absorption and release rate of carbon dioxideThe ratio of the exhaust gas recirculation gas to the total amount of gas to be burned in the internal combustion engine is relatively low compared with the case of low carbon dioxide storage rate.Diagram
