摘要： PROBLEM TO BE SOLVED: To prevent nonburnable ash growing in particle diameter from being accumulated in a diesel particulate filter (DPF), in an exhaust after-treatment device having DPF. SOLUTION: In this exhaust emission control device for an internal combustion engine, an ECU 8 estimates progress of growth in particle diameter of the ash accumulated in the DPF 33 based on an operational status of the engine 1. If it is determined that an estimated particle diameter value of the ash through the progress of growth in particle diameter exceeds a predetermined value, the regeneration of the DPF 33 is compulsorily performed even when a quantity of particulate matters accumulated in the DPS is lower than a reference value, at which the DPF should be regenerated. Thus, the particulate matters are eliminated through combustion, and the ashes are discharged from the DPF 33. COPYRIGHT: (C)2005,JPO&NCIPI

SOLUTION: An Electronic Control Unit 51 determines whether an accelerator opening degree change rate is small and an exhaust gas flow rate is large or not, calculates the collecting quantity from differential pressure and an exhaust flow rate in the DPF 4 if affirmation is determined, obtains the increment of the collecting quantity based on the exhaust quantity of the exhaust gas fine particles from an engine body 1 known from a fuel injection quantity or the like if negation is determined, and adds the increment to the collecting quantity calculated from the differential pressure or the like at the time of determining the negation at the latest to a present collecting quantity. The ECU 51 obtains the present collecting quantity with the calculated collecting quantity as a base when the affirmation is determined, and the collecting quantity is accurately obtained from the differential pressure or the like, thereby substantially compressing the error of the collecting quantity to the error of the increment of the collecting quantity even if the accelerator opening degree change rate is large or the exhaust gas flow rate is small and collecting quantity detecting accuracy is not sufficient.

摘要： PROBLEM TO BE SOLVED: To provide a compression ignition type internal combustion engine wherein NOx, smoke, and combustion noise are simultaneously suppressed.
SOLUTION: When ECU 2 judges that the operation condition of an engine 1 is in a specific operation region, it controls so as to inject the fuel dividedly twice in one cycle (pre-injection and post-injection). After the pre-injection is finished, combustion of the pre-injection is started, after the combustion of the pre-injection is finished, post-injection is stared, and after the post-injection is finished, combustion of the post-injection is started. In the above combustion mode, after an air-fuel mixture, which has fully vaporized during the delayed ignition, is injected, a slow combustion is started. Consequently, NOx and smoke can be simultaneously suppressed. Besides, since the number of injection is divided twice, the combustion quantity at a time is restrained to suppress also the combustion noise.
