Abstract: An engine exhaust gas ozone purification method, comprising: mixing a ozone stream and an exhaust stream to react, and removing nitric acid in a reaction product of the ozone stream and the exhaust stream mixture. A gas that has a nitric acid mist is caused to flow through a first electrode (301). When the gas that has the nitric acid mist flows through the first electrode (301), the first electrode (301) charges the nitric acid mist in the gas, and a second electrode (302) applies an attractive force to the charged nitric acid mist, so that the nitric acid mist is moved toward the second electrode (302) until the nitric acid mist adheres onto the second electrode (302). The present engine exhaust gas ozone purification method does not need to add a large amount of urea, and the purification effect is good.
