Description
Technical field
The utility model belongs to the engine manufacturing technology field, specifically, relates to a kind of new automobile engine cylinder-body.
Background technique
At present, along with motor being extensive use of of each engineering field, various engineering vehicles are to the power output of motor, performances such as power per liter are all had higher requirement; And along with the further strictness of environmental regulation, maximum outbreak pressure and temperature during engine combustion also improve constantly, and make the strength and stiffness of engine cylinder-body body are had higher requirement.
Conventional method is in casting process, by improving castability and increase the requirement that the external reinforcing muscle satisfies the housing structure strength and stiffness, and at a lot of stiffening ribs of cylinder body disposed outside to satisfy rigidity requirement.For oil return, special spill port can be set simultaneously, so just increase the weight of cylinder body, for satisfying the more stiffening rib of rigidity requirement needs design.Adopt prior art to improve the engine cylinder-body structural strength, can cause the increase of motor manufacture cost, engine weight to increase, and influence the space that external engine is arranged, and then influence the overall performance of motor.
The model utility content
Technical problem to be solved in the utility model is, adopt prior art to improve the engine cylinder-body structural strength, can cause the increase of motor manufacture cost, engine weight to increase, and influence the space that external engine is arranged, and then influence the technical problems such as overall performance of motor, and provide a kind of new automobile engine cylinder-body.
Technological scheme provided by the utility model is, a kind of new automobile engine cylinder-body comprises cylinder, and a side of described cylinder is provided with the spill port that improves housing structure rigidity.
Described spill port is the irregular section spill port that runs through end face and bottom surface on the cylinder body.
Described spill port is arranged in the air inlet side and/or the exhaust side of cylinder block.
When the quantity of described cylinder was one or more, described spill port was arranged between every adjacent two cylinders.
Described spill port specifically is arranged in described air inlet side between two cylinders one or have one or respectively have one in the intake and exhaust side at exhaust side.
Described spill port runs through the last end face and the bottom surface of cylinder body, and its part wall thickness in the cylinder body outside is 3-5mm.
Described spill port can obtain by casting and/or machining.
Adopt technological scheme provided by the utility model, can effectively solve when improving engine cylinder-body intensity, prior art can cause the motor manufacture cost to increase, engine weight increases, and influence the space that external engine is arranged, and then influence the technical problems such as overall performance of motor, simultaneously, the utility model is improved the rigidity of cylinder body by the organization plan of optimizing, adopt this scheme will make part under the constant situation of cost, improved the structural rigidity of cylinder body, alleviate the weight of cylinder body, improved the performance of motor, and had the function of ventilation oil return.
Description of drawings
In conjunction with the accompanying drawings, the utility model is further described
Fig. 1 is the utility model cylinder deck structural representation;
Fig. 2 is the utility model cylinder body bottom surface structural representation;
Wherein, 1 is cylinder body; 2 is spill port.
Embodiment
Shown in Fig. 1-2, technological scheme provided by the utility model is, a kind of new automobile engine cylinder-body 1 comprises cylinder, and a side of described cylinder is provided with the spill port 2 that improves cylinder body 1 structural rigidity; Described spill port 2 is for running through the irregular section spill port 2 of end face and bottom surface on the cylinder body 1; State air inlet side and/or exhaust side that spill port 2 is arranged in cylinder block 1; When the quantity of described cylinder was one or more, described spill port 2 was arranged between every adjacent two cylinders; Described spill port 2 specifically is arranged in described air inlet side between two cylinders one or have one or respectively have one in the intake and exhaust side at exhaust side; Described spill port 2 runs through the last end face and the bottom surface of cylinder body 1, and its part wall thickness in cylinder body 1 outside is 3-5mm; Described spill port 2 can obtain by casting and/or machining.
The utility model provides a kind of novel organization plan, improves the structural rigidity of big-block engine cylinder body 1 by the structural design of optimizing.
The utility model cylinder body 1 structure is mainly used on the motor, especially effect is obvious on large-scale diesel engine, this structure mainly shows as: on the cylinder body 1 of multicylinder engine, there is one or have one or an irregular section spill port 2 that runs through end face and bottom surface on the cylinder body 1 is arranged in the air inlet side between every two adjacent cylinder in the intake and exhaust side at exhaust side, this spill port 2 can obtain by casting, also can obtain, also can use casting and machining to obtain simultaneously by machining.The main effect of this spill port 2: 1, the ventilation oil return of cylinder body 1.2, the rigidity of raising cylinder body 1.3, alleviate cylinder body 1 weight.
Technological scheme provided by the utility model, on the cylinder body 1 of multicylinder engine, there is one or have one or an irregular section spill port 2 that runs through end face and bottom surface on the cylinder body 1 is arranged in the air inlet side between every two adjacent cylinder in the intake and exhaust side at exhaust side, this spill port 2 can obtain by casting, also can obtain, also can use casting and machining to obtain simultaneously by machining.The main effect of this spill port 2: 1, the ventilation oil return of cylinder body 1.2, the rigidity of raising cylinder body 1.3, alleviate cylinder body 1 weight.
