ユレイト再生時期判定処理装置。 The amount of particulates generated is calculated sequentially based on the signals from the intake air amount detection means and the fuel flow rate detection means, and the particulate collected amount is determined by multiplying the successively calculated amounts of generation by a correction coefficient based on the collection time and integrating them. 1. A particulate regeneration timing determination processing device, comprising a control means for controlling the regeneration means to be driven when it is determined that the collected amount exceeds a set value.
