摘要： PROBLEM TO BE SOLVED: To inhibit excitation force acting on a turbine blade of a turbine wheel. SOLUTION: Target supercharging pressure is established from a parameter (S2). Rotation speed of the turbine wheel is calculated from the parameter (S4) when an operation condition is an acceleration condition (S3). Opening of a variable nozzle is controlled to become larger than predetermined opening (S7) when calculated rotation speed of the turbine wheel is in a resonance zone (S5) and opening of the variable nozzle is smaller than the predetermined opening (S6). Consequently, excitation force is reduced and damage of the blade can be avoided. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To stably improve the regeneration efficiency of a filter regardless of variation in injection of a fuel injection valve in an exhaust emission control device of an engine for regenerating a filter 65 provided in an exhaust system of an engine by performing after-injection. SOLUTION: A regeneration means 91 for burning fine particles captured by a filter 65 performs after-injection control (regeneration control) when the quantity of fine particles captured amounts become to a predetermined value, and performs extending control for increasing the fuel injection quantity in the after-injection so that a rising rate of exhaust gas temperature flowing into the filter 65 is the predetermined value when the rising rate is smaller than a predetermined value after the start of regeneration control.

摘要： PROBLEM TO BE SOLVED: To regenerate DPF 17 in a short time without fusing the DPF 17 and worsening the rate of fuel consumption. SOLUTION: When the amount of particulates accumulated on the DPF 17 is a preset value or larger, subsidiary injection control for injecting fuel in an expansion stroke after main injection of the fuel is executed to supply unburnt fuel to an oxidation catalyst 16 so that the temperature of exhaust gas flowing into the DPF 17 is increased by the oxidizing reaction to burn and remove the particulates. At first, a subsidiary injection amount is controlled depending on the operated condition of an engine, and after the temperature of the DPF 17 is increased, the subsidiary injection amount is feedback controlled so that the temperature of the DPF 17 gets to a target temperature.
