Abstract
The utility model relates to a recovering and purifying device for motorcycle waste gas, which is characterized in that: a. a waste gas outlet of a crankcase is connected with an input end of an oil-gas separator (3),and the gas output end of the oil-gas separator is connected with a carburetor by air filters to form a recirculation mechanism for crankcase waste gas; b. fresh air output ends of the right air filter and left air filter are connected with the input end of an air cut-off valve (11) by a conductor tube; the positive pressure end of the air cut-off valve is communicated with an one-way valve by the conductor pipe (10); the output end of the one-way valve is communicated with an exhaust passage (6) which is additionally arranged at an exhaust valve by air conductor pipes (8, 7); the negative pressure end of the air cut-off valve is communicated with the air inlet pipe of the carburetor by pipes (12, 13)to form a secondary air purification mechanism for motorcycle tail gas.
Description
(1), technical field
The utility model relates to motorcycle tail gas cleaning and crankcase waste gas recycling device, promptly a kind of motorcycle waste gas reclaiming clean device.
(2), technical background
In the prior art, the waste gas of crankshaft box of motorcycle engine and the waste gas behind the engine combustion is all unprocessed directly to be entered atmosphere and had not only wasted energy, but also caused pollution to environment.
(3), Fa Ming content
Technical problem to be solved in the utility model provides and is a kind ofly purified by crankcase waste gas re-circulation means and tail gas secondary air that mechanism forms, can overcome the prior art above shortcomings, can energy saving and reduction discharging motorcycle waste gas reclaiming clean device.
It is such that the utility model solves the problems of the technologies described above the technological scheme that is adopted, and promptly a kind of motorcycle waste gas reclaiming clean device comprises Carburetor, cylinder head, the crankcase of motorcycle, left and right air-strainer; It is characterized in that: the waste gas outlet of a, crankcase is connected with the input end of a deaerator, and the gas output end of deaerator connects Carburetor and constitutes the crankcase waste gas re-circulation means through air-strainer; The fresh air output terminal of b, left and right air-strainer is connected with an air cutoff valve input end by conduit, the positive pressure side of air cutoff valve is communicated with an one-way valve by conduit, the one-way valve output terminal is by the secondary air three-way pipe, and the exhaust passage of setting up with the exhaust valve place is communicated with, the negative port of air cutoff valve is communicated with the suction tude of Carburetor by conduit and constitutes motorcycle exhaust secondary air purification mechanism.

(5), embodiment
Embodiment of the present utility model is referring to accompanying drawing, and motorcycle waste gas reclaiming clean device comprises Carburetor 1, cylinder head, the crankcase of motorcycle, left and right air-strainer among the figure; It is characterized in that: the waste gas outlet of a, crankcase is connected with the input end of a deaerator 3, and the gas output end of deaerator connects Carburetor and constitutes the crankcase waste gas re-circulation means through air-strainer; The fresh air output terminal of b, left and right air-strainer is connected with an air cutoff valve 11 input ends by conduit, the positive pressure side of air cutoff valve is communicated with an one-way valve 9 by conduit 10, the one-way valve output terminal is by air conduit 8,7, is communicated with the exhaust passage 6 that the exhaust valve place sets up, the negative port of air cutoff valve is communicated with the suction tude 2 of Carburetor by conduit 12,13 and constitutes motorcycle exhaust secondary air purification mechanism.
The utility model is owing to described structure, and when negative pressure appearred in air inlet and exhaust piper, air cutoff valve was closed, otherwise air cutoff valve is opened.
Working procedure of the present utility model is such: 1, the working principle of crankcase waste gas re-circulation means: the higher crankcase waste gas of temperature comes out from crankcase, on the one hand, oil duct through deaerator 3 maze types fully cools off, and machine oil is frozen into liquid and flows back to crankcase.Save the machine oil consumption, also reduced machine oil and enter combustion chambers burn, thereby reduced the carbon distribution of waste gas such as CO, HC and firing chamber.On the other hand, gases such as the CO in the waste gas, HC enter air-strainer by conduit 14, air cutoff valve 11, one-way valve 9 and enter combustion chambers burn through Carburetor and become CO
2And H
2O reduces the pollution of waste gas such as CO, HC to atmosphere.2, the motorcycle exhaust secondary combustion air purifies the working principle of mechanism: fresh air enters through one-level from left and right sides air-strainer and filters, be pooled to a three-way pipe 14 by two conduits and flow into air cutoff valve 11, carry out the filtration second time through air cutoff valve again and flow to one-way valve 9, the air bonding of cleaning is to the reliability of valve film.Utilize the outlet pipe pressure wave that the air of air-strainer is imported in the air outlet flue 6, the further oxidation reaction under the effect of secondary air with HC in the exhaust and CO generates H again
2O, CO
2Air cutoff valve prevents after-burning (exhaust explosion) function when throttle suddenly closes.One-way valve prevents exhaust adverse current function.
