Abstract
A regeneration controller for preventing particulate matter from increasing when an exhaust purification apparatus is inactivated. The regeneration controller includes an ECUfor heating the exhaust purification apparatus and eliminating the particulate matter accumulated in the exhaust purification apparatus when an estimated accumulation amount is greater than a reference accumulation amount. The ECUobtains the estimated accumulation amount by estimating the amount of particulate matter accumulated in the exhaust purification apparatus. An exhaust temperature sensordetects the temperature of the exhaust purification apparatus. The ECUintermittently decreases the air-fuel ratio of exhaust to heat the exhaust purification apparatus and perform burn-up heating for burning the particulate matter. The ECUfurther prohibits burn-up heating when the temperature detected by an exhaust temperature sensordecreases to a catalyst inactivation level.
