Description
Technical field
The utility model belongs to field of internal combustion engine, relates to a kind of Six-Cylinder Diesel Engine Motor body, relates in particular to a kind of seam wet type Six-Cylinder Diesel Engine Motor body down.
Background technique
Development trend based on home and abroad internal-combustion engine industry, China's road and non-road Abgasgesetz are sound day by day, and research and development are satisfied state III, state IV and exported the new product of the high-performance low emission of American-European developed country, the developing goal that new technology has become domestic internal-combustion engine industry.
Present domestic wet cylinder body diesel engine generally adopts seam location cylinder sleeve, raising along with the diesel engine strengthening degree, the increase of cylinder-firing pressure, the suffered lateral force of cylinder liner increases, the shortcoming of last seam location manifests gradually, cylinder-liner distortion under the effect of lateral force causes the cylinder leakage tester amount to increase.Therefore, design a kind of seam wet cylinder body down, make the cylinder sleeve positioning spigot in the bottom, the cylinder sleeve upper-end surface is compressed by cylinder cap, will make the cylinder sleeve location more reliable.
The model utility content
The purpose of this utility model is to provide a kind of wet type Six-Cylinder Diesel Engine Motor body that limits seam location under bore spacing, the cylinder liner, to solve the problem that cylinder-liner distortion, cylinder leakage tester amount increase under the high pressure of explosion effect in cylinder that seam location wet cylinder liner exists, for road vehicle, medium-sized engineering machinery and other off roader provide a power plant of new generation with high reliability, energy-conserving and environment-protective that satisfy domestic and international emission regulation demands.
The technical solution of the utility model is: a kind of seam wet type Six-Cylinder Diesel Engine Motor body down, six cylinder liner mounting holes that design on the body end face, adjacent two cylinder liner mounting hole centre distance size B2 are 139mm～141mm, six cylinder head bolt attachment holes of every cylinder are 38.5mm～40.5mm with respect to each cylinder liner mounting hole center size A1, A2 is 81mm～83mm, A3 is 79mm～81mm, and B1 is 69mm～71mm; The water hole is 55mm～58mm with respect to each cylinder liner mounting hole center size A4 on four cylinder head cooling waters of every cylinder, B3 is 52mm～55mm, two push-rod holes of every cylinder are 100mm～104mm with respect to each cylinder liner mounting hole center size A5, and A6 is 96mm～102mm, and B4 is 25mm～27mm.Seam diameter of phi A is 132mm～134mm on six identical cylinder liner mounting hole sizes, and following seam diameter of phi B is 127mm～129mm, and the seam end face is 123mm～125mm to the body end face apart from Q under the cylinder sleeve.
The utility model can reach following good effect after adopting technique scheme: the cylinder liner of following seam location, reduced the distortion of piston lateral forces therapeutic method to keep the adverse qi flowing downward cylinder sleeve, thereby reduced the air leakage of cylinder, the while wet cylinder liner is compared dry cylinder liner and can be improved cooling effect, reduce discharged nitrous oxides, wet cylinder body has the advantage that casting manufacturability is good, reject rate is low again.The utility model has guaranteed that by the checking of optimum Design of Structure and analog computation designed cylinder body can satisfy the requirement of the interior maximum functional pressure of explosion of cylinder to strength of machine body and rigidity.
