Title: Exhaust emission control device for internal combustion engine
Inventor: TAMURA YASUKI
IPC: F01N3/08
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine which can restrain the deterioration of a fuel consumption and drivability and release a sulphur component efficiently and surely. SOLUTION: This exhaust emission control device for an internal combustion engine is provided in an exhaust gas passage and provided with a catalyst absorbing the sulphur component in an exhaust gas under a first operation state in which an exhaust air fuel ratio is an oxydation atmosphere and releasing the sulphur component absorbed under a second operation state in which a high temperature and exhaust air fuel ratio are a restoration atmosphere. In that device, in a second operation state (S12, S14), the exhaust flow rate poured in the catalyst by a flow rate reduction means is properly reduced (S18). Therefore, even if the exhaust temperature and exhaust air fuel ratio are changed (S20, S22), the catalyst is held in the high temperature and restoration atmosphere.

Filed: 1988-12-01
Abstract: PURPOSE:To increase a system speed by generating an internal address latch signal having three cycles in one memory cycle and operating the data of a plane and writing the arithmetic result in another plane in each cycle period. CONSTITUTION:When an operation mode setting signal MODE is a high level, the internal address latch signal having three cycles in one memory cycle is generated in a control circuit 108.
