Described a kind of motorcycle oil-saving purifier is characterized in that AIR Air Injector Reactor comprises secondary air injection tube, leaf valve, air cutoff valve; Leaf valve is made up of valve seat, valve gap, reed; Air cutoff valve is made up of suction port seat, valve body, loam cake, valve film, poppet shaft, valve core spring and piston; Secondary air injection tube one end communicates with engine exhaust pipe, and the other end communicates with the air outlet of leaf valve, and the suction port of leaf valve communicates with the air outlet of air cutoff valve, and the suction port of air cutoff valve communicates with atmosphere; Be contained in air cutoff valve on the negative pressure pipe that covers communicate with engine intake; Move up and down with the control valve diaphragm, drive the suction port that piston opens or closes air cutoff valve thereupon.Utilize negative exhaust pressure that fresh air is imported in the engine exhaust port and mix, make it that oxidation reaction take place, reduced noxious gas emission with waste gas.Can prevent also that high engine speeds when running from producing blows out phenomenon.

Described a kind of motorcycle oil-saving purifier is characterized in that the surface of TWC Three Way Catalytic catalyst is cellular, and is coated with precious metal; Its role is to the carbon monoxide in the waste gas, hydrocarbon are converted into carbon dioxide and water.

The utility model is compared with prior art, has that structure is comparatively simple, fuel saving ratio is high, gives off the few advantage of harmful gas in the tail gas.Contrast adopts the harmful gas in the motorcycle engine exhaust gas discharged of the present utility model to be lower than common motorcycle by experiment, and [CO] reaches below 2.5%, and [HC] reaches below the 300ppm, can reach the standard of country and relevant local environmental regulation.
