Abstract
The utility model provides a ventilation structure of an automobile engine cylinder body, which belongs to the technical field of automobiles and solves the problem that the prior art has constraint on the product structure and poor ventilation effect although the structural arrangement is simple and easy to fabricate or the problem of the prior art that has complex structure and difficulty in casting process and has high risk of eccentric core or broken core although the ventilation effect is good and the structural arrangement is convenient. The ventilation structure of the automobile engine cylinder body on which at least two crankshaft chambers are arranged comprises ventilation units in the same number as the crankshaft chambers and positioned in one-to-one correspondence to the crankshaft chambers. Each ventilation unit comprises a main oil passage positioned on the cylinder body and a ventilation oil passage, the ventilation oil passage and the corresponding crankshaft chamber are both positioned on one side of the main oil passage, and one end of the ventilation oil passage is communicated with the crankshaft chamber and the other end thereof is communicated with the main oil passage. The ventilation paths of the main oil passages and the ventilation oil passages are smooth and the ventilation effect is effectively improved.
Description
Technical field
The utility model belongs to automobile technical field, relates to the aeration structure of a kind of motor car engine, particularly a kind of automobile engine cylinder body.
Background technique
When engine operation, total some inflammable mixture and waste gas are in piston ring is scurried crankcase, scurry and to make machine oil thinning after gasoline vapour in the crankcase condenses, performance depreciation, inflammable mixture and waste gas are scurried in the crankcase, pressure in the crankcase will be increased, and machine oil can ooze out and runs off from crank shaft oil seal, crankcase liner etc.The machine oil steam that is lost in the atmosphere can strengthen the pollution of motor to atmosphere.Motor is equipped with crankcase bleeder just can avoid or alleviate above-mentioned phenomenon.
The cylinder block crankshaft case aeration structure is the structural element of that it(?) must emphasis in the cylinder block design consider in engine for automobile.Crankcase ventilation oil duct and vent hole thereof are arranged the structural strength to cylinder body, the compactedness that complete machine is arranged, even all certain influence can be arranged to machine performance and discharging.Traditional crankcase ventilation road has two classes usually, and it is fairly simple that a class is arranged, is easy to casting, but big and ventilation effect is bad to the structural constraint of product; Another kind of structure more complicated, ventilation effect are arranged well than being easier to, but casting manufacturability is bad, easily the disconnected core of core shift.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the aeration structure of the good automobile engine cylinder body of a kind of ventilation effect.
The purpose of this utility model can realize by following technical proposal: a kind of aeration structure of automobile engine cylinder body, at least have two crankcase chamber on the cylinder block, it is characterized in that this aeration structure comprises identical with crankcase chamber quantity and position unit ventilators one to one; Described unit ventilators comprises main oil gallery and the ventilation oil duct that is positioned on the cylinder block, and ventilation oil duct and corresponding crankcase chamber all are positioned at a side of main oil gallery, and an end of described ventilation oil duct is connected with crankcase chamber, and the other end is connected with main oil gallery.
In the aeration structure of above-mentioned automobile engine cylinder body, the connecting port of described ventilation oil duct and crankcase chamber is positioned on the sidewall of crankcase chamber.
The connecting port of this ventilation oil duct and crankcase chamber is positioned at the middle part of crankcase chamber sidewall, and then in casting process ventilation oil duct and the oil duct core of main oil gallery and the cylinder barrel core of crankcase chamber, oil duct core and cylinder barrel core can be located mutually when core assembly, thereby improve the accuracy of core assembly location, effectively improve cylinder body rigidity and intensity; Simultaneously, provide stressed support when pouring into a mould, prevent that the oil duct core from skew and phenomenon of rupture taking place for cylinder blank.
Compared with prior art, the ventilation oil duct is connected main oil gallery in the aeration structure of this automobile engine cylinder body with crankcase chamber; Simultaneously, the ventilation route smoothness of main oil gallery and ventilation oil duct, the effectively ventilation effect that improves.

Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, automobile engine cylinder body 1 has 4 crankcase chamber 4.The aeration structure of this automobile engine cylinder body 1 comprises identical with crankcase chamber 4 quantity and position unit ventilators one to one.
Specifically, unit ventilators comprises a main oil gallery 2 and ventilation oil duct 3 that is positioned on the cylinder block 1, and ventilation oil duct 3 and corresponding crankcase chamber 4 all are positioned at a side of main oil gallery 2, and crankcase chamber 4 is identical with respect to the position of main oil gallery 2 in all unit ventilators.One end of ventilation oil duct 3 is connected with crankcase chamber 4, and the other end is connected with main oil gallery 2.Crankcase chamber 4 has end wall and sidewall between end walls and the bottom surface that is parallel to each other; The above-mentioned ventilation oil duct 3 and the connecting port of crankcase chamber 4 are positioned at the middle part of crankcase chamber 4 sidewalls.Ventilation oil duct 3 is connected main oil gallery 2 with crankcase chamber 4; Simultaneously, the ventilation route smoothness of main oil gallery 2 and ventilation oil duct 3, the effectively ventilation effect that improves.
Extremely shown in Figure 6 as Fig. 1, because ventilation oil duct 3 is positioned on crankcase chamber 4 sidewalls with the connecting port of crankcase chamber 4, and then in casting process the cylinder barrel core 5 of oil duct core 6 and the crankcase chamber 4 of ventilation oil duct 3 and main oil gallery 2, when core assembly, can locate mutually, thereby improve the accuracy of core assembly location, effectively improve cylinder body rigidity and intensity; Simultaneously, provide stressed support when pouring into a mould, prevent that oil duct core 6 from skew and phenomenon of rupture taking place for cylinder blank.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used cylinder block 1 morely; Main oil gallery 2; Ventilation oil duct 3; Crankcase chamber 4; Cylinder barrel core 5; Oil duct core 6 terms such as grade, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
