WORK VEHICLE WITH EXHAUST PURIFICATION SYSTEM
An object of the present invention is to provide an exhaust gas cleaning system for an engineering vehicle, the exhaust gas cleaning system being capable of performing the manual regeneration control in a proper state in which the manual regeneration control of a filter for collecting particulate matter included in an exhaust gas and the operation of the work system do not influence each other in a travelling engineering vehicle such as a hydraulic excavator. The operation (manual regeneration control) of a regeneration fuel injector 40 is started only under the following conditions: a manual regeneration starting switch 39 is enabled; an engine control dial 2 is operated such that the engine control dial 2 instructs the low-speed idle revolution speed; and a gate lock lever 22 is switched to a second position B at which generation of control pilot pressures a through f by use of remote control valves 25, 26, and 27 is disabled. Even when the manual regeneration control is being executed, if the gate lock lever 22 is switched to a first position A, the manual regeneration control immediately ends.
