ABSTRACT:
When an engine cooling water temperature (Tw) detected by a cooling water temperature detection means (37C) exceeds a predetermined judgment water temperatures (Tw1and Tw2) during the forced regeneration control of a filter using exhaust gas temperature raising means (351C), the actuation of the exhaust gas temperature raising means (351C) is interrupted.Thereby, in the case of the exhaust gas purification system having a DPF apparatus (13), it is possible to prevent a water temperature meter in a driver seat from abnormally rising during the forced regeneration of a DPF (13b) and to prevent a driver from taking the abnormal rise of the water temperature meter for an engine trouble.
