20090000277 | Exhaust Gas Purification Apparatus For Internal Combustion Engine - A fuel addition valve that adds fuel into the exhaust gas passage of the engine in the form of fine fuel droplets, an upstream NOx adsorption-reduction catalyst, and a downstream NOx adsorption-reduction catalyst are arranged in this order. Platinum Pt and palladium Pd, as noble metal, are supported on the downstream NOx adsorption-reduction NOx catalyst such that the ratio of the mole number of the platinum Pt to the sum of the mole numbers of the platinum Pt and the palladium Pd is approx. 50% to approx. 80%. Only platinum Pt is supported on the upstream NOx adsorption-reduction catalyst. According to this structure, even when liquid fuel is supplied into exhaust gas, NOx can be effectively released from the NOx adsorption-reduction catalyst, and further the amount of NOx that the NOx adsorption-reduction catalyst can adsorb at a low temperature increases. | 01-01-2009 |

20090199548 | EXHAUST GAS PURIFICATION SYSTEM AND METHOD FOR INTERNAL COMBUSTION ENGINE - Engine air-fuel ratio controlling means is provided to control an exhaust air-fuel ratio that is the ratio between the air contained in the exhaust gas discharged from the engine and the fuel element contained in the same exhaust gas and acting as a reducing agent at a NOx catalyst by controlling the air-fuel ratio of the gas combusted in the engine. Fuel adding means is provided upstream of the NOx catalyst in an exhaust passage to add fuel into the exhaust gas.
