<p>PURPOSE:To prevent any trouble which is caused by discontinuance of regeneration by writing a on-generation display signal for displaying on-regeneration of a filter in a non-volatile memory, in an exhaust gas purifying process for burning particulates by an electrically heating means, and displaying the on-regeneration signal at the time of starting of regeneration when discontinuance of regeneration is generated. CONSTITUTION:A particulate collecting amount is calculated by a memory map on the basis of exhaust pressure in front and rear of a filter 2 which are detected by pressure sensors 7, 17 and engine rotational speed which is detected by a rotational speed sensor 18, a lamp 91 for assigning regeneration of the filter 2 is lightened when the collected amount exceeds a prescribed threshold value. The advance step of regeneration motion which is memorized in a non-volatile memory which is stored in a controller 8 is displayed on a stage displaying lamp 92. It investigates whether regeneration is completed or not. When regeneration is not completed, it is assume that discontinuance is generated in previous regeneration, and a regeneration discontinuance lamp is turned on. When an operator judges on the basis of display of the lamp 92 or the regeneration discontinuance lamp that regeneration is affirmative, a starting switch is turned on, and execution of regeneration is instructed.</p> |
