Abstract
The invention provides an improved water cavity structure of a diesel engine body, which can solve the problems of non-uniform cooling water distribution, non-uniform water flow field and poor local cooling effect existing in the conventional diesel engine body using a square water cavity structure. The water cavity structure comprises the diesel engine body and a cylinder sleeve, wherein a cavity formed between the inner wall of the body and the cylinder sleeve is a diesel engine body water cavity; the water cavity structure is characterized in that: both the inner wall of the body and the cylinder sleeve are circular; and the diesel engine body water cavity formed by the circular inner wall of the body and the circular cylinder sleeve is a circular water cavity.
Description
Technical field
The present invention relates to Diesel Engine Technique Field, be specially a kind of improved diesel-engine body water cavity structure.
Background technique
General diesel-engine body water cavity is between the inwall and cylinder liner of diesel-engine body; Cooling water flows in water cavity and plays the effect of cooling air cylinder sleeve; Mostly the water cavity structure that adopts in the industry at present is square structure, sees Fig. 1 and Fig. 2, and the cavity that forms between the inwall 7 of diesel-engine body 1 and the cylinder liner 2 is a water cavity 10; Wherein the inwall 7 of diesel-engine body 1 is that square, cylinder liner 2 is for circular; Its shortcoming is the water yield skewness spatially in the water cavity, and because the existence of corner 8 on the inwall 7 of diesel-engine body 1, thereby the current in the water cavity very easily form local turbulent flow makes cooling water flow velocity in water cavity slow down, influence cooling effect; And gather the iron rust that washes away in the water cavity easily at a side body corner place, cause inhomogeneous, the local cooling effect variation of water flow field.
Summary of the invention
To the problems referred to above, the invention provides a kind of improved diesel-engine body water cavity structure, it can solve, and the cooling water water distribution that diesel-engine body in the past adopts square water cavity structure to exist is inhomogeneous, water flow field is inhomogeneous and the problem of local cooling effect difference.
Its technological scheme is such; It comprises diesel-engine body and cylinder liner; The cavity body that forms between the inwall of said body and the said cylinder liner is the diesel-engine body water cavity; It is characterized in that: the inwall and the cylinder liner of said body are circle, and the diesel-engine body water cavity that the body inwall of said circle and cylinder liner form is circular water cavity.
It is further characterized in that: the body internal face of said diesel engine two adjacent cylinder body is the plane that is parallel to each other; Said water cavity bottom and water channel hole bottom are at grade; The outer wall of said diesel-engine body and said inwall are all circle.
Compare with the normal diesel-engine body water cavity structure that adopts of present industry; Beneficial effect of the present invention is: its diesel-engine body inwall and cylinder liner are circle; So do not have corner in the circular water cavity of its formation; Cooling water in the water cavity is difficult for producing the phenomenon of turbulent flow, thereby can effectively reduce cooling-water flow resistance, raising flow of cooling water speed, guarantees cooling effect; And the cooling water flow field is even in the circular water cavity, is difficult for producing local situation uneven in temperature, can effectively improve the reliability of complete machine; And adopt circular water cavity, and wash away iron rust in the water cavity and be difficult for gathering, further guaranteed the uniformity of water flow field, guaranteed cylinder liner each several part cooling effect uniformity; Body inwall between the two adjacent cylinder body is parallel to each other and has guaranteed the wall thickness between each cylinder body, and water cavity bottom and water channel hole bottom help the discharge fully of cooling water on same plane; Body outer wall and body inwall are all round structure, can further guarantee the body consistent wall thickness, and it is uneven to reduce the body casting stress, improve the body reliability.
