Abstract
The invention provides an air filter capable of separating oil from vapor. The air filter comprises a base. An oil and vapor separation chamber is arranged in the base, an oil and vapor feeding channel and an oil return channel are arranged on one side of the base and are communicated with the oil and vapor separation chamber, an oil return channel check valve which closely clings to the oil return channel is arranged on the oil return channel, an air outlet channel which is communicated with the oil and vapor separation chamber is arranged on the other side of the base, and both the oil and vapor feeding channel and the air outlet channel are higher than the oil return channel. The air filter has the advantages that the oil can be effectively separated from the vapor, so that the engine oil can be prevented from being burned by an engine, resistance generated when oil and vapor are fed into the channel can be reduced, and accordingly output power of the engine is unaffected.
Description
Technical field
The present invention relates to a kind of air filter that can carry out oily vapour separation.
Background technique
Air filter base and the oily vapour separate mode of the general gasoline engines widely using at present mainly contain two kinds of structures: the first is in engine cowl hood or resuscitation apparatus, through the crankcase waste gas of preliminary oily vapour separation and machine oil steam and a certain amount of machine oil oil droplet, to be incorporated in the oily vapour inlet passage of air filter base, and oily vapour inlet passage operated by rotary motion is above the cylinder air inlet road of air filter base, the problem that this structure exists is, through containing proportional higher machine oil steam and machine oil oil droplet in the crankcase waste gas of preliminary oily vapour separation, machine oil steam can alter or flow into cylinder air inlet road along oily vapour inlet passage with machine oil oil droplet with crankcase waste gas, can cause engine burn oil thus, silencing apparatus emits blue smoke, exhaust emissions exceeds standard, befouling environment, the second is in engine cowl hood or resuscitation apparatus, through the crankcase waste gas of preliminary oily vapour separation and machine oil steam and a certain amount of machine oil oil droplet, to be incorporated in the oily vapour inlet passage of air filter base, and oily vapour inlet passage is arranged on the below in the cylinder air inlet road of air filter base, a back oil road is set below oily vapour inlet passage and leads to crankcase simultaneously, one-way valve is set in back oil road, utilize the negative pressure of crankcase that unnecessary machine oil is sucked back to crankcase by back oil road one-way valve, but the part that the problem that this structure exists is oily vapour inlet passage arranges too much---there is mazy composite guide air drain, oil baffle, oil outlet one-way valve and valve seat, seal ring etc., so just cause complex structure, assemble more complicated, cost is high, and because Assembly part is more in oily vapour inlet passage, cause exhausted by crankcase resistance to increase, thereby reduced the power stage of engine.
