Purification method for exhaust gas |
| abstract |
PURPOSE: To purify exhaust gas of an internal combustion engine by removing oxides of nitrogen, carbon monooxide, and hydro-carbon in the exhaust gas. n CONSTITUTION: An exhaust gas passage 2 of an internal combustion engine is divided into two. When a combustion condition of the internal combustion engine is lean, exhaust gas passes through a passage in which catalytic converter rhodium is charged, and when the combustion condition of the internal combustion engine is stoichio? or rich, the exhaust gas passes through a passage in which copper-contained crystalline silicate or copper-contained zeolite catalyst is charged. n COPYRIGHT: (C)1992,JPO&Japio |
