Abstract
A dust removal method for engine exhaust gas includes the steps of using an exhaust gas ionization dust removal electric field to gather particles in the exhaust gas, and using same to charge an exhaust gas electret element (205). The exhaust gas electret element (205) is close to or is provided at an outlet of an exhaust gas electric field device (1021). The dust removal method for engine exhaust gas can efficiently treat the engine exhaust gas and exhaust gas emissions.
