摘要： An exhaust purification system includes an LAF sensor provided in an exhaust pipe and generates a signal corresponding to an air-fuel ratio of exhaust gas. An upstream catalytic converter is downstream of the LAF sensor and has a catalyst to purify the exhaust gas. An O2 sensor is downstream of the upstream catalytic converter, and generates a signal corresponding to the air-fuel ratio of the exhaust gas. A GPF is downstream of a the O2 sensor and purifies the exhaust gas. An ECU controls an air-fuel mixture in an engine using output signal KACT of the LAF sensor and an output signal VO2 of the O2 sensor such that the air-fuel ratio of exhaust gas flowing into the GPF converges to a target value near the stoichiometric ratio. The GPF has a filter substrate and a downstream TWC supported by a partition of the filter substrate.

摘要： An exhaust purification device purifies an exhaust gas exhausted from an internal combustion engine. The exhaust purification device has a three-way catalytic agent that is located in an exhaust passage of the internal combustion engine and a particulate filter that is located downstream of the three-way catalytic agent in the exhaust passage and that collects an exhaust particulate. The particulate filter is provided with cells that includes sealed-inlet cells of which upstream ends are sealed and through cells through which an upstream side and a downstream side of the particulate filter communicate with each other. The particulate filter is arranged at a location where a temperature of the exhaust gas reaching an upstream end of the particulate filter is higher than or equal to a combustion temperature of the exhaust particulate, when the three-way catalytic agent is in an active state and when the internal combustion engine is operated.
