Abstract
The utility model discloses a crankcase waste gas treatment device of universal gasoline engine, which includes a crankcase with a discharge port, a waste gas pipe and an air filter, which is characterized in that an oil-gas separator is mounted in the air filter, an air intake end of the oil-gas separator is communicated with the waste gas pipe, an air outlet end of the oil-gas separator is communicated with an air filter. For the crankcase waste gas treatment device of universal gasoline engine of the utility model, the fog waste engine oil discharged from a discharge port is oil-gas separated, then the engine oil is returned to the crankcase for internal circulation, thereby to effectively decrease the consumption of the engine oil. The fog waste engine oil discharged from a discharge port is oil-gas separated, then the fog engine oil entering into the carburetor is greatly decreased, and the engine oil entering into the combustion chamber to be burned is significantly decreased, therefore the incompletely burned engine oil in waste gas is decreased, the quantity of pollutants discharged by the gasoline engine is effectively reduced, in particular to the quantity of pollutants formed by incompletely burned engine oil. The utility model has simple and practical structure.
Description
Technical field
The utility model relates to a kind of attached processing device parts of general gasoline engines, especially general gasoline engines waste gas treater for crankshaft box.
Background technique
The crankcase of four stroke engine communicates with gearbox, is linked to be an integral body; In crankcase, be placed with lubricant oil, relative movement part surface is lubricated,, prolong its working life to reduce resistance to motion.Owing to drive the rotation of the mobile oil pump of lubricant oil, the rotation of gearbox internal speed-changing gear, stir lubricant oil at a high speed, produce vaporific machine oil, make crankcase pressure be in state of changing, crankcase is in communication with the outside, can discharge waste gas when needed.
Because the work characteristics of general gasoline engines, can make the vaporific machine oil of part along with waste gas comes out by the exhausted by crankcase orifice flow, because the needs of environmental protection and the restriction of strict emission control standards, the waste gas of discharging from exhaust port does not directly enter in the atmosphere now, the common vaporific machine oil waste gas of this part is introduced directly into suction tude to be mixed with fuel oil, sucks at last in the cylinder and burns with fuel oil.First deficiency of this kind mode is the consumption that has increased machine oil, has wasted machine oil; Its second deficiency is befouling environment, discharged more pollutant; Because the physics or the chemical characteristics of machine oil and fuel oil (gasoline, diesel oil) differ greatly, machine oil is not easy to burn fully, can cause carbon distributions such as firing chamber, valve, and the machine oil of not burning fully can produce discharge pollutants more, be unfavorable for environmental protection and usually make of the restriction of the pollutant of general gasoline engines discharging, limit its field of employment or using scope above relevant criterion.
Summary of the invention
The treatment of waste gas mode of discharging in the exhausted by crankcase hole of the utility model at prior art, the above-mentioned deficiency of structure provide a kind of consumption that can reduce machine oil, reduce the general gasoline engines waste gas treater for crankshaft box of the amount of pollutants of gasoline exhaust.
The technical solution of the utility model: the general gasoline engines waste gas treater for crankshaft box comprises the crankcase that has exhaust port, flue gas leading and empty filter; It is characterized in that: in empty filter inside deaerator is set, the inlet end of deaerator is communicated with flue gas leading, and the outlet side of deaerator is communicated with empty filter;
Further feature is: transition chamber is set on the deaerator, and the position of transition chamber is higher than the position of the exhaust port of crankcase.
General gasoline engines waste gas treater for crankshaft box of the present utility model with respect to prior art, has following characteristics:
The vaporific machine oil waste gas of 1, discharging from exhaust port is after Oil-gas Separation, and machine oil can be back in the crankcase and recycle, and effectively reduces the consumption of machine oil.
The vaporific machine oil waste gas of 2, discharging from exhaust port is after Oil-gas Separation, the vaporific machine oil that enters in the Carburetor significantly reduces, together entering the oil level of being burnt the firing chamber with fuel oil significantly reduces, make do not have perfect combustion in the tail gas oil level seldom, effectively reduce the amount of pollutants of gasoline exhaust, particularly the amount of pollutants that forms because of imperfect combustion machine oil reduces greatly.
3, simple in structure, practical.

Accompanying drawing is the utility model structure diagram;
Embodiment
As shown in the figure, 1-crankcase, 2-exhaust port, 3-flue gas leading, 4-empty filter, 5-deaerator, 6-transition chamber;
General gasoline engines waste gas treater for crankshaft box of the present utility model, comprise in the crankcase 1 that has exhaust port 2, empty filter 4 is empty filters of prior art, flue gas leading 3 couples together the exhaust port 2 of crankcase 1 with empty filter 4, the waste gas that contains organic oil that the exhaust port 2 of crankcase 1 is discharged enters in the sky filter 4, makes the waste gas that contains organic oil and fuel oil, air etc. be mixed into the engine combustion Indoor Combustion at last.Because the physics or the chemical characteristics of machine oil and fuel oil (gasoline, diesel oil) differ greatly, machine oil is not easy to burn fully, can cause carbon distributions such as firing chamber, valve, and the machine oil of not burning fully just enters atmosphere, befouling environment as discharging pollutants.Above as prior art, be not further described at this.
General gasoline engines waste gas treater for crankshaft box of the present utility model, its improvement are in empty filter 4 inside deaerator 5 to be set, and the inlet end of deaerator 5 is communicated with flue gas leading 3, and the outlet side of deaerator 5 is communicated with empty filter 4; The waste gas that contains organic oil that the exhaust port 2 of crankcase 1 is discharged, in flue gas leading 3 enters deaerator 5, centrifugation through deaerator 5, most of machine oil is separated in deaerator 5, separated machine oil accumulates in the transition chamber 6, recycles in flue gas leading 3 is back to crankcase 1.
The effect of deaerator 5 is separated oil, its structure has multiple, deaerator of the prior art can be consulted name and be called " deaerator ", the patent No. is 03234996.3 Chinese utility application file, and name is called " motor oil gas separator-filter ", the patent No. is 200420032521.7 Chinese utility application file, perhaps name is called " motorcycle engine gas and oil separating plant ", the patent No. is the Chinese utility application file of 200520010444.X, and name is called " motorcycle oil-gas separator ", the patent No. is 200620109982.9 Chinese utility application file, above as prior art, be not further described at this.
As further improvement of the utility model, transition chamber 6 is set on deaerator 5, separated machine oil accumulates in the transition chamber 6, recycles in flue gas leading 3 is back to crankcase 1.In order to make the machine oil that deposits can rely on deadweight to flow back in the crankcase 1, the position of transition chamber 6 should be higher than the position of the exhaust port 2 of crankcase 1.
The utility model is arranged on deaerator 5 in the sky filter 4, perhaps deaerator 5 is integrated on the sky filter 4, and is simple in structure, can effectively reduce oil consumption and the discharging that improves motor.
