<p>PURPOSE: To delay the clogging of an exhaust purifying filter, prolong the life of an exhaust purifier, and facilitate the reproduction of the purifying filter. CONSTITUTION: An exhaust purifier 2 is provided on the exhaust path 1 of an engine, and a purifying filter 3 is stored in the exhaust purifier 2. The exhaust purifier 2 and purifying filter 3 are formed into a cylindrical shape respectively, a primary chamber 7 is formed between the outer periphery of the purifying filter 3 and the inner face of the peripheral wall 6 of the exhaust purifier 2, and a secondary chamber 8 is formed on the inside of the purifying filter 3 respectively. An exhaust inlet 4 is opened on the peripheral wall 6 of the exhaust purifier 2, and the exhaust path 1 is connected to the exhaust inlet 4 from the diagonally tangential direction. The exhaust 10 guided into the primary chamber 7 is spirally swirled around the purifying filter 3, and it flows into the secondary chamber 8 through the purifying filter 3.</p> |
