ABSTRACT:
An exhaust gas purifying device for removing harmful solid particles, sparks and flames contained in exhaust gas discharged from an internal combustion engine comprises a cylindrical body member connected to a muffler in an exhaust gas system of the engine. The cylindrical body member is separated into front and rear chambers by an intermediate partition plate. The front chamber includes an exhaust gas introducing hole in a front wall thereof and displaced with respect to a communicating hole formed in the central portion of the partition plate to thereby effectively remove the harmful particles at low flow rate of the exhaust gas. The rear chamber includes a swirl-generating means on the upstream side thereof and a solid particle collecting chamber on the outer periphery thereof to thereby remove the harmful particles at high flow rates of the exhaust gas.
