<p>PURPOSE:To effectively eliminate NOx in such a way that in case where a vehicle goes uphill and downhill, in order to prevent liquid in a chemical liquid reservoir from flowing out, a slit is installed on an exhaust passage, whereupon reticular cloth or the like is provided. CONSTITUTION:A chemical liquid reservoir 2 exists under an exhaust passage 1, in which is suspended a membrane 3 supported at its upper end by an optional suspender 7 from the upper end 6 of the passage. The membrane is required that it facilitates the passage of exhaust containing NOx, liquid is sucked through its surface tension via a membrane 3' in the liquid reservoir, and sucked liquid goes up until the upper end. The membrane has a narrow slit 5 installed at the part of a lid 8 of the chemical liquid reservoir 2 passed and strongly constricted at the slit part. In consequence, when the vehicle goes uphill and downhill, liquid in the liquid reservoir is prevented from flowing out of it because there is the constricted slit part.</p> |
