Abstract
An exhaust-gas purifying device purifies an exhaust gas exhausted from a gasoline engine of a vehicle and flowing in an exhaust pipe, and has a purifying function part disposed in the exhaust pipe and a detector located downstream of the purifying part in the exhaust pipe. The purifying function part has a three-way catalyst that oxidizes and reduces a toxic substance and a filter that collects a particular matter included in the exhaust gas. The detector detects an amount of the particular matter based on electrical conductivity between the electrodes of the detector. The detector is located at a position that is one meter distanced from a downstream end of the purifying function part in a path length of the exhaust pipe or a position at which a temperature of the exhaust gas flowing after a warm-up operation of the gasoline engine is lower than or equal to 450° C.
