Abstract:
1. An exhaust gas cleaning system for a construction machine comprising: a diesel engine; a starting/stopping command device for issuing commands to start and stop the engine; a plurality of driven bodies actuated by motive power of the engine; operating means for issuing an operating command to each of the driven bodies; and an operational limiter actuated selectively to either a first position (A) to enable operation of the operating means, or a second position (B) to disenable the operation of the operating means, wherein the exhaust gas cleaning system comprises: a filter disposed in an exhaust system of the engine in order to trap any particulate matter included in exhaust gases; a regenerating device which regenerates said filter by increasing an engine exhaust gas temperature so as to burn off the particulate matter deposited therein; and a regeneration control device which activates said regenerating device while keeping operation of the engine when the starting/stopping command device issues the engine-stopping command with the operational limiter in the second position (B) and stops the engine and operation of the regenerating device when the regeneration of the filter is terminated.
