The power assembly includes a battery. The electrolysis assembly includes a reservoir filled with an electrolyte. The electrolysis assembly also includes an anode electrode a cathode electrode disposed into the reservoir. The anode electrode and the cathode electrode are connected to the battery. The electrolysis assembly produces oxygen and dihydrogen. The oxygen is captured by the hollow tower. The ozone assembly includes a fan that allows the oxygen to cross the hollow tower. The ozone assembly further includes a plurality of ultraviolet lights to convert the oxygen into ozone. The ozone is replenishment into the atmosphere.

An engine tail gas ozone purifying system and method. The engine tail gas ozone purifying system comprises reaction fields (220, 202) used for mixture reaction of an ozone stream and a tail gas stream. A large amount of urea does not need to be added and the purification effect is good.

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.

In a discharge generator, a control unit switchably performs a continuous mode and a burst mode based on determination of whether target output power is higher than discharge start power. The burst mode alternately performs a discharge mode and a non-discharge mode. The control unit causes a burst ratio to be set to a value expressed by the following equation b=Po*/P.sub.fs0 where b represents the burst ratio, Po* represents the target output power, and P.sub.fs0 represents the discharge start power. The burst ratio is defined as a ratio of the discharge period to a burst period. The burst period is the sum of the discharge period and the stop period. The control unit causes, in the burst mode, the switch circuit to output, as the output power, the discharge start power during the discharge period.
