Abstract
An exhaust gas purifier for removing unburned solid particles, sparks, and flames contained in exhaust gas discharged from internal and external combustion engines includes a closed cylindrical member connected to the exhaust port of an internal or external combustion engine and a swirl-generating member disposed in the cylindrical member and provided with a plurality of swirl vanes for swirling the exhaust gas, whereby the length of time that the exhaust gas is disposed in the cylinder is extended and unburned solid particles, sparks, and flames contained in the exhaust gas are centrifugally separated and extinguished thereby discharging relatively clean gas.
