Abstract
The utility model discloses a diesel engine cylinder block which comprises a cylinder block body, a cylinder hole, an arc surface structure and a cam shaft hole. The diesel engine cylinder block is characterized in that under the condition that the overall performance of a diesel engine is kept or improved, vermicular graphite cast iron HT250 materials are used for casting the diesel engine cylinder block, reinforcing ribs are arranged on the outer wall of the diesel engine cylinder block, and the rigidity requirement and the strength requirement of the cylinder block are raised. The vermicular graphite cast iron is adopted in the cylinder block, and the purposes of optimizing the appearance, lowering weight and reducing cost can be achieved by reducing the wall thickness, optimizing the structure and increasing the reinforcing bars. The matching oil consumption of the whole diesel engine cylinder block is lower, and the competitiveness of the diesel engine is improved.
Description
Technical field
The utility model relates to Diesel Engine Technique Field, relates in particular to a kind of cylinder structure for diesel engine.
Background technique
Along with automobile industry development, automobile is more and more higher to diesel engine requirement, lightweight, and low oil consumption is exactly wherein the most typical two requirements.In whole diesel engine running, the factor that affects lightweight and low oil consumption is many-sided.Cylinder of diesel engine is exactly one of them key factor, and therefore, in Diesel Engine Development, improve the rigidity of cylinder block and require lightweight, be important measures with the discharge and the oil consumption that reduce diesel engine.
Cylinder block of the prior art adopts HT250 casting, and in order to reach the requirement of rigidity, just very thick and heavy of cylinder block, causes complete machine overweight, and oil consumption is high.
Summary of the invention
The purpose of this utility model is to overcome defect in above-mentioned prior art, by adopting vermicular graphite iron material, optimize casting, process for machining, the wall thickness of reasonable Arrangement cylinder of diesel engine, keeping the at present same of cylinder block rigidity, the weight that effectively reduces cylinder block reduces discharge and the oil consumption of motor simultaneously.
Technical solution of the present utility model is such, a kind of cylinder of diesel engine, comprise cylinder block body, cylinder-bore, globoidal structure, camshaft hole, it is characterized in that cylinder block body 1 inner chamber top is cylinder-bore 2, there is camshaft hole 4 cylinder block body 1 inner chamber below, and there is globoidal structure 3 in the outer wall skirt section, below of cylinder block body 1, and the wall thickness of cylinder block body 1 is 1～10mm, the outer wall of cylinder block body 1 has stiffening rib, and cylinder block body 1 adopts vermicular cast iron HT250 cast blocks.
The lonely stiffening rib of cylinder block body 1 outer wall has more than 1.
Camshaft hole 4 is opened the side at cylinder of diesel engine body 1.
Compared with prior art, the utlity model has following beneficial effect:
1, adopt vermicular cast iron, can significantly improve cylinder block rigidity, reduce cylinder block weight;
2, can reduce cylinders of cylinder block bore deformation, reduce Lubrication Oil Consumption in Diesel Engine, thereby reduce diesel emission simultaneously;
3, the reduction of cylinder block weight, when coupling car load, reduces oil consumption;
4, can make the outward appearance of motor more attractive in appearance.
Brief description of the drawings
Fig. 1 is the part sectioned view of the utility model cylinder of diesel engine.
Reference character: cylinder block body 1, cylinder-bore 2, globoidal structure 3, camshaft hole 4.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Embodiment 1, considering maintenance or improving in diesel engine overall performance situation, cylinder of diesel engine 1 is by adopting vermicular graphite iron material, optimize casting, process for machining, the wall thickness of reasonable Arrangement cylinder of diesel engine, can significantly improve the rigidity of cylinder block, can effectively reduce the weight of cylinder block, reduce discharge and the oil consumption of motor simultaneously.A kind of cylinder of diesel engine, comprise cylinder block body, cylinder-bore, globoidal structure, camshaft hole, it is characterized in that cylinder block body 1 inner chamber top is cylinder-bore 2, there is camshaft hole 4 cylinder block body 1 inner chamber below, there is globoidal structure 3 in the outer wall skirt section, below of cylinder block body 1, the wall thickness of cylinder block body 1 is 1～10mm, and the outer wall of cylinder block body 1 has stiffening rib, and cylinder block body 1 adopts vermicular cast iron HT250 cast blocks.The lonely stiffening rib of cylinder block body 1 outer wall has more than 1.Camshaft hole 4 is opened the side at cylinder of diesel engine body 1.
Embodiment 2, and the outer wall up and down of cylinder block body 1 has stiffening rib, and stiffening rib is " X " font structure.Cylinder of diesel engine body 1 adopts vermicular cast iron HT150～HT250 casting.The wall thickness of cylinder block body 1 is 10～20mm.
Embodiment 3, and the upper lower wall of cylinder of diesel engine body 1 has stiffening rib, and stiffening rib adopts " work " font structure, and cylinder of diesel engine body 1 adopts vermicular cast iron HT250～HT350 casting.Cylinder block body 1 wall thickness is 0.5～1mm.
Cylinder structure for diesel engine of the present utility model can significantly improve cylinder block rigidity, reduces cylinder block distortion; Can reduce cylinders of cylinder block bore deformation, thereby reduce Lubrication Oil Consumption in Diesel Engine, engine oil consumption is the key factor that affects diesel emission, therefore can reduce diesel emission simultaneously; The reduction of cylinder block weight, when coupling car load, oil consumption is lower; Cylinder-block skirt globoidal structure around can make the profile of motor more attractive in appearance.
Disclosed is above only a specific embodiment of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
