An apparatus for purifying exhaust gas having an exhaust gas purifier and a recovering pipe extending from the exhaust gas purifier to a suction device of an internal-combustion engine. The exhaust gas purifier collects soot, etc., in the exhaust gas to purify the exhaust gas under an action of adiabatic expansion, which exhaust gas is discharged from the engine. The recovering pipe feeds the soot, etc., with the gas purified by the exhaust gas purifier into the suction device in which the soot, etc., and the purified gas are mixed into fresh air for combustion. |
