摘要： In regeneration control, when the catalyst temperature index temperature (Tg2) using the temperature of the oxidation catalyst (12a) as an index is below a predetermined first determination temperature (Tc1), the engine speed of idling is brought to a predetermined first target engine speed (Neil) which is higher than the engine speed of idling (Nei0) in the ordinary operation, and, further, multi-injection is carried out. On the other hand, when the catalyst temperature index temperature (Tg2) is the predetermined first determination temperature (Tc1) or above, the engine speed of idling is brought to a predetermined second target engine speed (Nei2), which is lower than the predetermined first target engine speed (Nei1) and is higher than the engine speed of idling (Nei0) in ordinary operation, and, further, post injection is carried out, followed by raising of the temperature of an exhaust gas flown into a DPF apparatus (12b) to a predetermined second determination temperature (Tc2). According to the above constitution, in the regeneration control of the DPF apparatus (12b) in an internal combustion engine (10), the regeneration can be forcibly carried out with high efficiency while enhancing the temperature rise efficiency of the exhaust gas, and, at the same time, excessive rise in the exhaust temperature, a deterioration in fuel consumption, and the occurrence of noise are suppressed.

摘要： In forced regeneration control of an exhaust gas purification device 12, the number of data for injection control such as the number of meshes of a data map and the number of data maps for multi injection control is decreased while occurrence of torque shock, which is a rapid fluctuation of a generated torque, is avoided. In the forced regeneration control of the exhaust gas purification device 12, when an operation state of an internal combustion engine 10 is a high-load operation state, the normal injection control by stopping the multi injection is carried out and according to a rotation speed Ne and a load Q of the internal combustion engine 10, a region for control is divided into a multi-injection control region Rm, a transition region Rt, and a normal injection control region Rn, and in the transition region Rt, data Ft(i) for injection control obtained by interpolation of data Fml(i) for injection control on the multi-injection control region Rm side and data Fnl(i) for injection control on the normal injection control region Rn side is used.
