Abstract
The utility model relates to a diesel engine body, of which the cylinder diameter ranges from 102 to 108mm, and solves the problems of top plate deformation of the engine body and deformation of cylinder liner bottom hole. A top plate of the engine body is enhanced in a water sleeve, and the thickness is identical to that of a boss of a cylinder cap screwed hole. Three inclined water channels are added, the inner diameter of the inclined water channels is identical to that of other water channel holes. Four reinforcing ribs are symmetrically arranged on the external circle of each cylinder liner bottom hole towards the water from the top to the bottom, thereby improving the rigidity and strength of the cylinder liner bottom holes, and reducing deformation degree of the cylinder liner. The diesel engine body can effectively reduce blowing of a cylinder head due to top plate deformation. The reinforcement of cylinder liner bottom hole lowers deformation degree of a cylinder liner, reduces the consumption of machine oil of the diesel engine, and improves the performance of the diesel engine.
Description
Technical field
The utility model belongs to the diesel engine technologies field, and being specifically related to a kind of cylinder diameter is 102～108mm direct spray type, 4 cylinder diesel bodies.
Background technique
Diesel-engine body is the kernel component in all component of diesel engine, and other each system all is attached on it, and its rigidity and intensity then directly influence the amount of deformation and the life-span of component.The diesel-engine body of dry liner adopts the top board thickness consistent at present, and the cylinder liner bottom outlet is outward the structure of cooling jacket, this structural configuration; The top board, cylinder liner bottom outlet that make diesel-engine body cause cylinder trepanning expanded by heating because temperature raises when diesel engine is worked, the result causes the ovality of cylinder trepanning bigger than normal; The diesel engine overall performance is exerted an influence, and can cause body top board local deformation and the distortion of cylinder liner bottom outlet, top board local deformation can cause diesel engine towards the cylinder bed; The distortion of cylinder liner bottom outlet simultaneously; Then can cause the diesel engine specific oil consumption to increase, waste machine oil, increase user cost.
Summary of the invention
For the problem that solves the distortion of body top board local deformation, cylinder liner bottom outlet, causes the diesel engine specific oil consumption to increase; It is the novel housing construction of diesel engine of 102～108mm that the utility model provides a kind of cylinder diameter; The body key position is strengthened; Make its more reasonable stress, cool off more sufficient reinforced multi-cylinder diesel engine body.
The concrete structure scheme is following:
A kind of diesel-engine body comprises water jacket 4 between body top board 2, four cylinder liner bottom outlets 7 and each the cylinder liner bottom outlet, and improvement is: the thickness of said body top board 2 is 4.8cm, and its bottom surface is concordant with cylinder head tapped hole boss 6;
Said body top board 2 is along the length direction of cylinder body, be provided with oblique water channel 3 between two straight water channels on the cylinder body top board between the adjacent cylinder liner bottom outlet 7; Two stomidiums of oblique water channel 3; One end is connecting water hole, a straight water channel upper end, and the other end is connecting another water hole, straight water channel lower end;
Said each cylinder liner bottom outlet 7 is arranged with four stiffening ribs 5 from top to bottom on its cylindrical.
The utility model is the optimal design that former organism is carried out; On hole system that keeps former body to greatest extent and processing technology basis; The crucial force part of body structure is optimized, reaches and let the body more reasonable stress, the purpose that diesel engine performance is improved.
Description of drawings
Fig. 1 is the utility model structural representation (laterally analysing and observe).
Fig. 2 is the sectional view A-A of Fig. 1.
Fig. 3 is the stiffening rib position sectional view B-B of Fig. 1.
Among the figure: 1-body, 2-top board, the oblique water channel of 3-, 4-water jacket, 5-stiffening rib, 6-cylinder head tapped hole boss, 7-cylinder liner bottom outlet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
A kind of cylinder diameter is the diesel engine body structure of 102～108mm.The thickness of body top board 2 is 4.8cm, and its bottom surface is concordant with cylinder head tapped hole boss 6; Body top board 2 is along the length direction of cylinder body, be provided with oblique water channel 3 between two straight water channels on the cylinder body top board between the adjacent cylinder liner bottom outlet 7; Two stomidiums of oblique water channel 3; One end is connecting water hole, a straight water channel upper end, and the other end is connecting another water hole, straight water channel lower end.
Referring to Fig. 1 and Fig. 2, body top board 2, oblique water channel 3 and cylinder sleeve bottom outlet stiffening rib 5, water jacket 4.
Body top board 2 reinforced structures are in original jacket space; It is concordant with cylinder head tapped hole boss 6 to increase thickness; Improve the intensity of body top board, set up the oblique water channel 3 in three places, the heat that causes to solve the top board thickening increases; Improve top board and add the strength radiating effect, tiltedly water channel 3 internal diameters are identical with other water channel hole internal diameter; Symmetry is set up and is arranged four stiffening ribs 5 (referring to Fig. 3) from top to bottom on each cylinder sleeve bottom outlet cylindrical; Simultaneously 4 length of the water jacket between each cylinder liner are shortened to the top board direction; Improve cylinder liner bottom outlet intensity and rigidity; Can effectively reduce the amount of deformation of cylinder liner bottom outlet, guarantee the reliability of diesel engine quality.
