<p>PURPOSE:To supress generation of smoke by detecting a capturing rate of particulates and its temporal fluctuation, and correcting an operation condition when the temporal fluctuation rate is specified value or more. CONSTITUTION:A capturing rate detection means A is provided on an exhaust particulate removing device of a diesel engine for detecting a particulate rate captured in a filter. Temporal fluctuation of the capturing rate is detected by a capturing rate fluctuation detection means B. In case that the temporal fluctuation rate is a specified value or more, an operation condition of the engine is corrected so as to suppress the generation of smoke by an operation condition correction means C. The particulate capturing rate per unit time is adjusted in the filter which is not in regeneration process, so as to be the value suitable for regeneration. The regeneration is thus carried out with certainty, and the frequency of regeneration is reduced.</p> |
