<p>PURPOSE:To eliminate properly clogged substances by incineration by a method wherein a voltage signal with respect to an information in suction and exhaust series and a standard voltage based on a revolving sped of an engine is compared and thereby the clogging of a collector is detected in the exhayst soot collector provided in an exhayst gas passageway. CONSTITUTION:Exhaust gas of an engien 21 is introduced into a collector 200 through an exhaust gas passageway 22 and is passed from an inner side chamber 12b into an outer side chamber 12a through a filter 4, thereafter, is dicharged from an exit 6. During this period of time, an exhaust gas pressure within the inner side chamber 12b is being acted in an upper stream chamber 13b of a detector 13' and a diaphragm 13b' is displaced until a position wherein the exhaust gas pressure and a resilient force of a spring 13c' is balanced. A resistance value of a variable resistor 25 is changed in accordance with the displacement thereof an thereby an input voltage V1 inout into a controlling circuit 27 is determined. Thereafter, when clogging of the filter 4 is progressed, said voltage V1 becomes higher and a deviation with respect to a standard voltage V2 for comparation is exceeded a predetermined valve, a relay 30 is closed by the controlling circuit 27 and collected fine particles may be incinerated by feeding electricity through an electric heating wire consisting the filter 4.</p> |
