Exhaust flow in the exhaust pipe (muffler) 5 In the channel 6 and the oxidation catalyst 8, the reduction catalyst 7 and the oxidation are two in the solid. In the present embodiment, the reduction catalyst 7 is a::: portion, and the oxidation catalyst 8 is provided in the exhaust pipe. After 5 ==3⁄4, the original catalyst 7 and the oxidation catalyst 8 can also be arranged in the rear part of the milk discharge tube 5 or other suitable position. The cooling fan 4 is used as a pressurization unit, and the engine is connected to the port fan 4, and the second tube 9 is connected to the drain of the reduction catalyst 7 and the oxidation catalyst. Thus, the engine cooling fan 4 can be utilized.运1258533 = Air is sent to the exhaust pipe 5 through the inlet pipe 9 to the flow rate of a, two into the exhaust pipe 5, increase the catalyst c catalyst 8 ^ reaction (10) of the air, reduce the emission of pollution catalyst (emulsified η =: Π, the present invention can also be connected to the other side of the fender 1 on the periphery of the wheel 3, and the guide tube 9 reduces the exhaust flow between the catalyst 7 and the oxidation catalyst 8. Road 6. Because: = the natural pressure generated when the wheel 3 rolls, the air is sent to the exhaust pipe 5 through the 4= into the rowing officer 5, and the flow rate of the secondary air into the exhaust pipe 5 is increased, and the catalyst catalyst is added. The air required for the reaction reduces emissions.曰 In addition, as shown in the fifth figure, the present invention can also be added to the vehicle - plus questions
