Abstract
The utility model discloses a device which can prevent a motor waste gas nozzle from spraying oil. The utility model comprises a motor external container bottle, a waste gas nozzle connecting tube, an oil returning tube and an air filer connecting tube, wherein, the container bottle is divided into two chambers through a filtering baffle plate, the waste gas nozzle connecting tube and one end of the oil returning tube are communicated with one chamber, one end of the air filter is communicated with the other cavity chamber, and the oil returning tube is communicated with the bottom part of the container bottle. The waste gas nozzle connecting tube, the oil returning tube and the other end of the air filter are respectively communicated with a waste gas nozzle, a case cover and the inlet opening of the air filer. The utility model can resolves the oil spraying phenomenon caused by the excessive inner pressure of the motor, therefore, motor oil can flow back to a crank case, can not flow away, and also can not block the air filter. The waste gas nozzle connecting tube, the container bottle, the oil returning tube and the crank case are jointly formed a motor oil circulating channel, and the good motor oil recovery effect can be ensured.
Description
Technical field
The utility model relates to the improvement technology of motor, can prevent the device of engine exhaust mouth oil spout on the concrete mean engine.
Background technique
At present, the waste gas in the crankcase is got rid of by the waste gas mouth on the casing mostly, enters the sky filter through the waste gas sebific duct that communicates with waste gas mouth again, enters combustion system again after filtering through empty filter and carries out second use.Along with the increase of engine displacement, crankcase pressure also increases thereupon, thereby causes the crankcase inner engine oil easily to spray in waste gas mouth, motor spray machine oil phenomenon promptly occurs.Fuel injection event is that motor institute is unallowed, the appearance of this phenomenon, and one side is accelerated the consumption of lubricating oil in the crankcase, and the lubricated cooling effect of influence forces the oiling frequency to increase, and increases user's cost of use; On the other hand, when the machine oil of ejection passed through empty filter in company with waste gas, machine oil can stick on the filter core, stopped up filter core, influenced empty filter proper functioning.The patent No. discloses the device that addresses this problem for the Chinese utility model patent " a kind of waste gas treater for crankshaft box of motorcycle engine " of " 011176288 ", it is made of housing, guide pipe and oil returning tube, the oil returning tube two ends are communicated with suction port and housing inner chamber respectively, though it also can solve fuel injection event in waste gas treatment, but because lubricant oil to enter and discharge housing all is by the suction port on the housing, be subjected to very big influence because waste gas enters housing so lubricant oil was understood when discharging.
The model utility content
At the prior art above shortcomings, a kind of device that can prevent the oil spout of engine exhaust mouth and be convenient to the machine oil recovery that the purpose of this utility model provides.
The technical solution of the utility model is achieved in that a kind of device that can prevent the oil spout of engine exhaust mouth, it comprises the external container bottle of motor, waste gas mouth connecting tube, return tube and empty filter connecting tube, one end of described waste gas mouth connecting tube, return tube and empty filter connecting tube is communicated with container bottle respectively, the other end is respectively applied for waste gas mouth, crankcase cover and empty filter inlet and is connected, and wherein return tube is communicated with the container bottle bottom.
Further improve and be that described container bottle is divided into two chambers by filter septum, waste gas mouth connecting tube and return tube are communicated with one of them chamber, and empty filter connecting tube is communicated with another chamber.
The utility model enlarges crankcase volume by container bottle and reaches the purpose that reduces crankcase pressure thus, can reduce the waste gas flow velocity, the machine oil of ejection can fully be precipitated, and stay in the container bottle, thereby solve the waste gas mouth fuel injection event that causes because of the motor internal pressure is excessive.Even organic oil sprays from crankcase, also be to enter container bottle and spray outside not understanding, can flow back to crankcase by return tube, thereby can not cause machine oil to run off, can not stop up empty filter yet.Waste gas mouth connecting tube, container bottle, return tube and crankcase form the oil circulation passage jointly, can guarantee good machine oil recovering effect.
The utility model is simple in structure, and fabricating cost is low, and other component on the motor need not done any change and just can be connected with this device.
Description of drawings
Fig. 1-the utility model structural representation.
Wherein, 1-container bottle; 2-waste gas mouth connecting tube; The 3-return tube; The empty filter connecting tube of 4-; The 5-filter septum; Solid arrow represents that exhaust flow represents that to, dotted arrow machine oil flows among the figure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises container bottle 1 (the about 1L of volume), waste gas mouth connecting tube 2, return tube 3 and empty filter connecting tube 4, and waste gas mouth connecting tube 2, return tube 3 and empty filter connecting tube 4 are sebific duct.Container bottle 1 is divided into two chambers by filter septum 5 (selecting asbestos gauge for use), waste gas mouth connecting tube 2 and return tube 3 one ends are communicated with one of them chamber, empty filter connecting tube 4 one ends are communicated with another chamber, and what wherein return tube 3 was communicated with container bottle 1 is the bottom of container bottle 1.The other end of waste gas mouth connecting tube 2, return tube 3 and empty filter connecting tube 4 is respectively applied for waste gas mouth, case lid and empty filter and is connected.Filter septum 5 can be isolated machine oil, prevents from that it from entering in the sky filter by empty filter connecting tube 4 to stop up filter core.Waste gas mouth connecting tube 2, container bottle 1, return tube 3 and crankcase form machine oil single cycle passage jointly, guarantee good machine oil recovering effect thus.Return tube guarantee with prerequisite that crankcase is communicated with under can be installed in any position of motor body, from concrete installation, be chosen in the motor right side usually and cover.
From the figure upward arrow as can be seen, the utility model waste gas both can enter container bottle from the waste gas mouth connecting tube, also can enter container bottle by return tube.Machine oil then can only enter container bottle from the waste gas mouth connecting tube, flows back to crankcase by return tube again, is single cycle.
The utility model has increased by a container bottle at external engine, with container bottle and crankcase internal switching, reaches the effect that enlarges the engine crankcase volume by pipeline.Container bottle is equivalent to the extension of crankcase volume, and waste gas mouth connecting tube and return tube are equivalent to the crankcase inner member, and empty filter connecting tube is equivalent to the flue gas leading of prior art.This kind design can increase crankcase volume under the situation that does not increase casing or lid volume, cost-saved.
