Abstract
An exhaust gas treatment filter removes particulate matter from exhaust gas of a diesel engine. The particulate matter which accumulates on the filter is removed by a manual regeneration system that can simply be controlled.After a manual regeneration switch 22 is shifted to an ON-position, a load control section 66 keeps at least one of the revolution speed N of an engine 1, the displacement volume q and discharge pressure P of a hydraulic pressure pump 11 at a corresponding first target value (N1, q1, or P1) or second target value (N2, q2, or P2) depending on a temperature of the cooling water in relation to a flame-out prevention temperature T1. A regeneration control section 67 starts the compulsory regeneration after the manual regeneration switch has been shifted to the ON-position and when the cooling water temperature is equal to or higher than T1.
