| titleOfInvention | Internal combustion engine exhaust gas purification system |
| abstract | Exhaust gas purification system of an internal combustion engine in which: a hydrocarbon feed valve (15) for feeding hydrocarbons is arranged in an engine exhaust gas duct (12a, 12b), a catalyst (13 ) of exhaust gas purification to react the NOX contained in the exhaust gases and reformed hydrocarbons is arranged in the engine exhaust gas duct (12b) downstream of the hydrocarbon feed valve (15), a sensor Downstream side air-fuel ratio (24) for detecting the air-fuel ratio of the exhaust gases is arranged in the engine exhaust duct (12b) downstream of the exhaust gas purification catalyst (13). exhaust, the downstream side air-fuel ratio sensor (24) is a kind of sensor having a solid electrolyte, electrodes respectively covering two side surfaces of the solid electrolyte, and a resistor layer nce to diffusion that covers one of the electrodes and in which the exhaust gases are guided over the layer of resistance to diffusion, catalysts (51, 52) of precious metals are carried on a surface (50) of gas flow exhaust gas of the exhaust gas purification catalyst (13) and a basic exhaust gas flow surface part (54) is formed around the precious metal catalysts (51, 52), characterized in that a sensor (23) upstream side air-fuel ratio for detecting an exhaust gas air-fuel ratio is arranged in the engine exhaust duct (12a) upstream of the hydrocarbon feed valve (15), the catalyst (13) exhaust gas purification has a property of reducing the NOx that is contained in the exhaust gases if a concentration of hydrocarbons flowing into the exhaust gas purification catalyst (13) is vibrated within an inter predetermined value of amplitude and within a predetermined interval of period and has a property of increasing the amount of NOx storage that is contained in the exhaust gases if the vibration period of the hydrocarbon concentration becomes longer than the predetermined interval , when the hydrocarbons are fed from the hydrocarbon feed valve (15), an air-fuel ratio detected by the downstream side air-fuel ratio sensor (24) changes to a rich side from an air-fuel ratio of reference that is detected when no hydrocarbons are fed from the hydrocarbon feed valve (15), and a quantity of hydrocarbons is detected that is fed from the hydrocarbon feed valve (15) and passes through the catalyst (13) exhaust gas purification from an air-fuel ratio difference between an air-fuel ratio that is detected average Note the upstream side air-fuel ratio sensor (23) and the reference air-fuel ratio which is detected by the downstream side air-fuel ratio sensor (24). |
