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 |

20100101217 | EXHAUST GAS PURIFICATION SYSTEM FOR INTERNAL COMBUSTION ENGINE - An object of the invention is to recover the capability of an exhaust gas purification apparatus provided in an exhaust passage of an internal combustion engine with improved reliability. According to the invention there are provided recovery control execution unit for executing a recovery control in which the temperature of the exhaust gas purification apparatus is raised by supply of reducing agent to a precatalyst to thereby recover the capability of the exhaust gas purification apparatus and prohibition range setting unit for setting a recovery control prohibition range that is an operation range of the internal combustion engine in which execution of the recovery control by the recovery control execution unit is prohibited. The higher the degree of deterioration of the precatalyst is, the higher the maximum values of the engine torque and the engine revolution number in the recovery control prohibition range are set to be. | 04-29-2010 |
20110162354 | EXHAUST PURIFICATION DEVICE OF INTERNAL COMBUSTION ENGINE - Particles smaller than 50 nanometers emitted from an internal combustion engine, and serving as nuclei for forming PM (particulate matter), are removed to decrease the number of PM particles that are emitted to atmosphere. High efficiency filters are provided in passages that feed fluids into the combustion chamber, e.g., intake air, fuel and engine oil, in order to remove particles smaller than 50 nanometers serving as nuclei for forming PM. | 07-07-2011 |
