Exhaust gas emission control device for removing damaging components collected in an exhaust gas purification unit comprises an exhaust gas purification unit, temperature sensors, a deposit detecting unit, and a releasing control unit

摘要

Exhaust gas emission control device comprises an exhaust gas purification unit (20) arranged in an exhaust gas installation of an I.C. engine (1), a first temperature sensor (18) for detecting the temperature of the exhaust gas leaving the combustion chamber of the engine, a second temperature sensor (22) for detecting the temperature of the exhaust gas flowing into the exhaust gas purification unit, a deposit detecting unit for calculating and detecting the amount of damaging components containing in the exhaust gas, and a releasing control unit to control when the amount of damaging components detected reaches a predetermined amount.
