<p>PURPOSE:To provide a diesel engine exhaust fine particle removing device for reducing the complexity of driving operation, and for elonging the interval of fine particle filtration part reproducing operation. CONSTITUTION:For an operation method of a diesel engine exhaust fine particle removal device in which a fine particle filtration part 3 is provided on the exhaust channel of a diesel engine 1, and a by-pass channel 4, a reproducing device 5 of the filtration part, as well as dampers 10, 12, 14 provided on these 3, 4, 5, and control valves 11, 13, 15 thereof are provided, when the diesel engine is going to be started or stopped, exhaust air is passed through the filtration part 3, while the exhaust air is passed through the by-pass channel at the time of driving operation. Since the filtration device is not operated when the amount of dust in the exhaust air is small, the longevity of the device is achieved, and the driving operation of the device is thus simplified.</p> |
