Abstract
The utility model discloses a waste gas separation structure in a crank shaft box body. A ventilation chamber in the crank shaft box body is partitioned into a plurality of layers of ventilation structures by a plurality of lubricating oil separation partition plates and a plurality of gas isolation plates; a left ventilation chamber is separated from a right ventilation chamber through a box body gasket clamped between a left box body and a right box body; therefore, more lubricating oil is adsorbed by the box body gasket and the lubricating oil separation partition plates in the box body in a process that mixed air of oil and gas is discharged through more paths in the left and right ventilation chambers, and the quality of air discharged from the box body is improved; meanwhile, the loss of the lubricating oil in the crank shaft box body is reduced; and the waste gas separation structure is used in the field of crank shaft boxes of motorcycle engines.
Description
Technical field
The utility model relates to the toxic emission field in a kind of crankcase, particularly relates to the waste gas separation structure in a kind of crankcase body.
Background technique
In the crankcase of motorcycle engine, when crankshaft operation, will drive piston and move up and down, thereby make interior negative pressure of crankcase and malleation alternately exist, so having through the ventilation mouth, the outside air of crankcase body gets into and the discharge crankcase.In the process that air gets into and discharges, get into the lubricant oil that splashes, atomizes that the object of the high speed rotating such as air and bent axle in the crankcase body causes and mix and form the fuel-air mixture body.
This fuel-air mixture body is full of at crankcase body inner by relevant air vent in casing; Play the surface lubrication of inner body; Get into and discharge in the process of crankcase at air, can the lubricant oil in the fuel-air mixture body in the casing be entered outside air and produce pollution.
Along with people's is to the attention of environmental protection; To the toxic emission of usually used motorcycle gasoline engine require increasingly high; General existing general-purpose petrol engine is provided with gas and oil separating plant usually on the engine crankshaft casing, through this gas and oil separating plant the waste gas of thermal expansion in the crankcase body is discharged, with the pressure in the balance crankshaft casing; Simultaneously the machine oil that mixes in the inherent waste gas of crankcase body is separated; Make isolated machine oil flow back into and be used in the crankcase body lubricate, and the waste gas that will isolate behind the machine oil is transported to air-strainer, get into the firing chamber again and participate in burning; Waste gas in the crankcase body can be discharged in the atmosphere, solve the waste gas problem in the crankcase body.
But mostly the air vent of the setting in the engine crankshaft casing was linear air vent in the past; Perhaps linear air vent is set to simple curvilinear structures; But this type of air vent all can not separate the lubricant oil in the fuel-air mixture body in the crankcase body fully, thereby inevitably can pollute surrounding enviroment.
The model utility content
For addressing the above problem, the utility model provide a kind of can more effective separation crankcase body in the waste gas separation structure of lubricant oil in the fuel-air mixture.
The utility model solves the technological scheme that its technical problem adopted:
Waste gas separation structure in a kind of crankcase body; Comprise the left side casing and the right side casing that constitute crankcase body; The top of right side casing is provided with the ventilation mouth; The below of ventilation mouth is provided with ventilation chamber in left side casing and right side casing, be provided with the casing pad that can the both sides ventilation chamber be separated between left side casing and right side casing, and the vent chamber of left side casing and right side casing is provided with multiple tracks lubricating oil separation dividing plate and gas separator plate.
Further as the improvement of the utility model technological scheme, the ventilation chamber below in the casing of right side is provided with the air balance chamber, the adjacent air balance hole that is provided with ventilation chamber in the air balance chamber, and the bottom of the ventilation chamber in the casing of right side is provided with the draining hole.
Further as the improvement of the utility model technological scheme, the multiple tracks gas separator plate of the vent chamber in the casing of left side is divided into curved arrangement to each other, and the bottommost of the ventilation chamber in the casing of left side is provided with drain pan.
Further as the improvement of the utility model technological scheme, the casing pad is provided with the vent that can be convenient to gas exchange between left side casing and right side casing.
The beneficial effect of the utility model: the waste gas separation structure in this crankcase body is divided into multi-level ventilation device through multiple tracks lubricating oil separation dividing plate and gas separator plate with the ventilation chamber in the crankcase body; And the ventilation chamber of left and right side is separated through the casing pad that is folded between left side casing and right side casing; Make in the process that the fuel-air mixture body is discharged from through more path in the ventilation chamber of both sides; Lubricant oil is more adsorbed by the lubricating oil separation dividing plate in casing pad and the casing; To improve the air quality of discharging in the casing, reduce the loss of crankcase body simultaneously to lubricant oil.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model embodiment's a right side box inner structure schematic representation;
Fig. 2 is the utility model embodiment's a left side box inner structure schematic representation;
Fig. 3 is the utility model embodiment's a casing gasket construction schematic representation.
Embodiment
With reference to Fig. 1～Fig. 3; The utility model is the waste gas separation structure in a kind of crankcase body; Comprise the left side casing 1 and right side casing 2 that constitute crankcase body, the top of right side casing 2 is provided with ventilation mouth 3, and the below of ventilation mouth 3 is provided with ventilation chamber 4 in left side casing 1 and right side casing 2; Left side casing 1 and 2 of right side casings are provided with the casing pad 5 that can both sides ventilation chamber 4 be separated, and are provided with multiple tracks lubricating oil separation dividing plate 6 and gas separator plate 7 in the ventilation chamber 4 of left side casing 1 and right side casing 2.
Waste gas separation structure in this crankcase body is divided into multi-level ventilation device through multiple tracks lubricating oil separation dividing plate 6 and gas separator plate 7 with the ventilation chamber in the crankcase body 4; And the casing pad 5 through being folded in 2 of left side casing 1 and right side casings separates the ventilation chamber 4 of left and right side; Make in the process that the fuel-air mixture body is discharged from through more path in both sides ventilation chamber 4; Lubricant oil is more adsorbed by the lubricating oil separation dividing plate 6 in casing pad 5 and the casing; To improve the air quality of discharging in the casing, reduce the loss of crankcase body simultaneously to lubricant oil.
