Abstract
A kind of engine crankcase of Oil-gas Separation, it comprises crankcase housing (1), cylinder body spill port (3) and ventilating hole (4), ventilating hole is communicated with resuscitation apparatus, a drain pan spill port (2) that communicates with the cylinder body spill port is set in the crankcase housing, this spill port upper end communicates with cylinder body spill port (3), the lower end communicates with the crankcase bottom surface, lubricant oil is got back to crankcase by the cylinder cap back oil road along the cylinder body spill port drain pan spill port of flowing through, and the waste gas in the crankcase then enters resuscitation apparatus along ventilating hole; Spill port (2) can be cast into to reprocess behind the integrative-structure and portal with crankcase 1, gets through with the crankcase bottom surface simultaneously during processing purge cock (5); Or directly be welded on the crankcase after shaping separately; It has solved the problem that the crankcase waste gas of conventional engines mixes with lubricant oil, because the outlet of drain pan spill port directly passes to the lubricant oil bottom, has therefore reduced the exhaust emission of motor, and has reduced consumption of lubricating oil.
Description
Technical field
The utility model relates to the crankcase of motor, especially a kind of engine crankcase of Oil-gas Separation.
Background technique
The structure of existing motor is: the lubricant oil on the cylinder cap is directly got back on crankcase 1 pasta after by cylinder body spill port 3.Because cylinder body spill port 3 and ventilating hole 4 communicate, waste gas in the crankcase also can directly lead to cylinder cap along spill port 3, when if crankcase pressure is big, taken back in the cylinder head cover by waste gas along the lubricant oil that spill port 3 flows back to, make to produce a large amount of oil gas in the housing, these oil gas are directly discharged outside the motor, in atmosphere pollution by resuscitation apparatus, make the machine oil in the crankcase constantly reduce, produce consumption of lubricating oil.
Summary of the invention
Deficiency at above-mentioned prior art existence, the utility model proposes a kind of engine crankcase of Oil-gas Separation, it is that a drain pan spill port that communicates with the cylinder body spill port is set in crankcase, this spill port upper end communicates with the cylinder body spill port, the lower end communicates with the crankcase bottom surface, the lubricant oil that engine cylinder covers is got back to crankcase by the cylinder cap back oil road along the cylinder body spill port drain pan spill port of flowing through, and the waste gas in the crankcase then enters resuscitation apparatus along ventilating hole.
The utility model has solved the problem that the crankcase waste gas of conventional engines mixes with lubricant oil, because the outlet of drain pan spill port directly passes to the lubricant oil bottom, and the waste gas in the crankcase can not enter spill port, has therefore reduced the exhaust emission of motor, and has reduced consumption of lubricating oil.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is crankcase 1 three-dimensional structure diagram in the utility model.
Fig. 3 is the A-A sectional drawing among Fig. 2.
Embodiment
Reach embodiment in conjunction with the accompanying drawings and describe, but protection domain of the present utility model is not limited to accompanying drawing and embodiment.
As shown in Figure 1, the utility model mainly contains crankcase 1, drain pan spill port 2, cylinder body spill port 3, ventilating hole 4, purge cock 5, and spill port 2 upper ends and cylinder body spill port 3 are connected, and the lower end directly communicates with the lubricant oil bottom surface.When crankcase completely had lubricant oil, drain pan spill port 2 separated with vent 4 lubricated oil, the waste gas in the crankcase through the pasta top to ventilating hole 4, can not enter in the spill port 2.
Described drain pan spill port 2 can be cast into to reprocess behind the integrative-structure and portal with crankcase 1, gets through with the crankcase bottom surface simultaneously during processing purge cock 5; Or directly be welded on relevant position on the crankcase after shaping separately.
Claims (2)
1, a kind of engine crankcase of Oil-gas Separation, comprise crankcase housing (1), cylinder body spill port (3) and ventilating hole (4), ventilating hole is communicated with resuscitation apparatus, it is characterized in that: a drain pan spill port (2) that communicates with the cylinder body spill port is set in the crankcase housing, this spill port upper end communicates with cylinder body spill port (3), and the lower end communicates with the crankcase bottom surface.
2, engine crankcase according to claim 1 is characterized in that: the drain pan spill port (2) of hollow is cast into integrative-structure with crankcase.
