Abstract
A cylinder body of an engine comprises cylinder holes, a water jacket around the cylinder holes and vertically penetrated oil return ducts. The oil return ducts are formed between the adjacent cylinder holes of the cylinder body; and the section of each oil return duct is in the shape of arranging a crank under the water jacket. The oil return ducts are formed on the air inlet side and the air exhaust side of the cylinder body. Because the shape of the adopted structure is completely different from that of the traditional direct type oil return ducts, the spaces of the oil ducts are cranked and extended, so as to not only achieve the oil return effect of f the oil return ducts, but also enhancing the effects of reducing the weight of the cylinder body and enabling lubricating oil to play a cooling role in the cylinder body.
Description
Technical field
The utility model relates to a kind of engine cylinder-body, particularly relates to a kind of design of back oil road shape of engine cylinder-body.
Background technique
Lubrication system is a vital constituent element of motor, general automotive engine lubrication system is with associated components work in combination such as fuel filter, oil pump, machine oil cooler, oil filter basically, lubricant oil is transported to the relevant moving element of motor, reaches effects such as lubricated, cleaning and cooling.The lubrication system of motor car engine carries the lubricant oil of cylinder cap need flow back in the oil sump of motor, to reach the purpose that recycles.Usually, lubricant oil is got back to oil sump through the passage that cylinder cap is connected with cylinder body.At present, the back oil road structure of common cylinder body mostly is drum, and is up big and down small structure shape.Back oil road is directly by the end face of the cylinder body bottom surface through to cylinder body.Though so structure can play the requirement of oil return or gas blowby, its deficiency is, at present common back oil road is spatially less, do not extend to the body plenum below the cylinder body upper cylinder half hole, causes the weight of cylinder body relatively large, heat dispersion is not good.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the available engine cylinder body to provide a kind of engine cylinder-body.Solve effective oil return of lubricant oil and cooling problem, reach simultaneously and alleviate cylinder body weight purpose.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of engine cylinder-body, described cylinder body comprise the back oil road of the water sleeve up/down perforation of cylinder hole, cylinder hole periphery; It is characterized in that: described back oil road is arranged in the centre in the adjacent cylinder of cylinder body hole, and the back oil road section shape is for there being individual crank throw below water jacket.
Described back oil road is all arranged in cylinder body air inlet side and exhaust side.
The crank throw top of described back oil road and water jacket distance from top value 5-10mm.
Described back oil road sectional shape is a rectangle.
Good effect of the present utility model: mainly show on special " fore-telling " word structural type of back oil road, be that the complete different and traditional cross section of this structure is a drum type cylinder body back oil road structure on the one hand, and adopt the special structure of rectangle; The 2nd, the shape of this structure is different from the back oil road shape of traditional straight-down type fully, the space that the part crank throw that " fore-telling " word stretches out has extended back oil road, not only played the oil return effect of back oil road itself, more to alleviating cylinder body weight and making lubricant oil obtain reinforcement to the cooling action of cylinder body.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the cylinder body organigram.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1. cylinder body, 2. cylinder hole, 3. back oil road, 4. water jacket, 5. crank throw.
Embodiment
As shown in Figure 1, 2, a kind of engine cylinder-body, described cylinder body 1 comprise the water jacket 4 of cylinder hole 2, cylinder hole periphery and the back oil road 3 of up/down perforation.Described back oil road 3 is arranged in the centre in the adjacent cylinder of cylinder body hole 2, and the back oil road section shape is for there being individual crank throw 5 below water jacket.Described back oil road 3 is all arranged in cylinder body air inlet side and exhaust side.Described back oil road 3 sectional shapes are rectangle.
Cylinder body back oil road of the present utility model is simple and compact for structure.The concrete shape of back oil road can be done different shape-designings according to the concrete structure of cylinder body.Because its particular structure shape is very easy to casting.When cast blocks, the back oil road core is through the moulding of simple mould time processing.With other core one-time positioning of cylinder body, the moulding of cast cylinder body.In addition, when the utility model is applied on the cylinder body, adopt the symmetrical structure form, make cylinder body main body structure intensity obtain very big reinforcement, use on the motor that very suitable performance is had relatively high expectations.
According to other data of cylinder body, determine the horizontal and vertical size between two back oil roads, and extend to the space on the cylinder body basis, so just can finish the design of back oil road.As shown in Figure 1, L represents adjacent cylinder hole centre distance among the figure.L1 is the cylinder body water jacket height, and L2 is the crank throw place height of back oil road.
Half (P=L/2) of back oil road central position (P)=cylinder hole centre distance,
L2=L1+ (5-10) (unit: mm).In the present embodiment, crank throw 5 tops of back oil road and water jacket 4 distance from top value 5-10mm.
Claims (4)
1, a kind of engine cylinder-body, described cylinder body comprise the back oil road of the water sleeve up/down perforation of cylinder hole, cylinder hole periphery; It is characterized in that: described back oil road is arranged in the centre in the adjacent cylinder of cylinder body hole, and the back oil road section shape is for there being individual crank throw below water jacket.
2, engine cylinder-body according to claim 1 is characterized in that: described back oil road is all arranged in cylinder body air inlet side and exhaust side.
3, according to claim 1,2 described engine cylinder-bodies, it is characterized in that: the crank throw top of described back oil road and water jacket distance from top value 5-10mm.
4, according to claim 1,2 described engine cylinder-bodies, it is characterized in that: described back oil road sectional shape is a rectangle.
