<p>PURPOSE: To make outputs of a burner rapidly and accurately follow load fluctuation of an engine by performing closed-loop control of the output of the burner on the basis of a function of a temperature generated downstream. CONSTITUTION: Output of an exhaust gas burner 2 for regenerating a particle filter 7 is controlled by using a fuel quantity closed-loop control device 10 to control the fuel from a fuel pump 9. Here, in a closed-loop and a closed-loop output control device 11, an intermediate pressure of an internal combustion engine 3 from an accelerator sensor 15, a speed of the internal combustion engine 3 from a speed sensor 16 and a temperature downstream from the burner in a middle segment 8 from a temperature sensor 17 are inputted as functions based on which the fuel quantity closed-loop control device 10 is controlled. As a consequence, the output of the burner 2 can be controlled to rapidly and accurately follow the load fluctuation of the internal combustion engine 3.</p> |
