Abstract
The utility model relates to an engine cylinder block, in particular to a V-shaped automobile engine cylinder block, and belongs to the technical field of automobile engines. The cylinder block comprises cylinder holes, left and right suspension faces, a V-shaped groove, a front end face and a rear end face, water inlets are formed in the two sides of the front end face of the cylinder block, the suspension faces are arranged on the left side and the right side of the cylinder holes, and the V-shaped groove is formed between the left and right suspension faces. The V-shaped automobile engine cylinder block is characterized in that the diameter of the water inlets is 28mm-32mm. The water inlets are formed in the centers of the two sides of the front end face. The cylinder block is formed by casting gray pig iron. The diameter of the water inlets of a V-shaped engineis set to be 28mm-32mm, the flow and flowing speed of cooling water of all cylinders can be effectively and evenly distributed, and the problem that the walls of all the cylinders of the engine are cooled unevenly can be effectively solved.
Description
Technical field
The utility model relates to a kind of engine cylinder-body, particularly relates to a kind of V-type automobile engine cylinder-body, belongs to technical field of automobile engine.
Background technique
Motor car engine is the heart component of automobile, the complex machines being formed by multiple mechanisms and system, and its Main Function is to realize the conversion of heat energy to mechanical energy.Housing assembly is the skeleton of motor, and all major parts and the annex of motor is installed, and bears the various load in motion.By cylinder body, the crankshaft & connecting of motor and distribution device and fuel feeding, skidding, the system such as cooling are connected into an entirety, the quality of processing of cylinder body directly affects the performance of motor.Its structure has left and right side to hang face, front/rear end.The housing assembly of traditional motor is mainly comprised of cylinder body, cylinder or cylinder liner, cylinder cap, head gasket and oil sump etc.Because the function of cylinder body has determined that it is complex-shaped, wall is thin, be box-shaped, and several only pits of machining are arranged at its top, for cylinder liner is installed.Its underpart and crankcase body top are made of one, so cavity is more, but stressed serious, so it should have very high rigidity, also to reduce casting section thickness, thereby alleviate its weight simultaneously.The stressing conditions that can know cylinder body according to the principle of motor is very complicated, need to have enough intensity, rigidity, wear resistance and vibration resistance, therefore cylinder block material is had to higher requirement.The material of cylinder body has plain cast iron, alloy cast iron and aluminum alloy etc.China's engine cylinder-body generally adopts HT200, HT250 gray cast iron, alloy cast iron and aluminum alloy.
Cylinder body bore section adheres to fuel combustion High Temperature High Pressure district separately, and cylinder barrel wall needs cooling, and cylinder barrel wall arranged outside is recirculated water cooling chamber system.This engine cylinder-body is because power demand is large in the market, and cooling water hole position distribution own is unreasonable, and each cylinder barrel outer wall cooling water water flow velocity is inhomogeneous; Cause the each cylinder barrel wall heat radiation of motor inhomogeneous, each cylinder barrel wall swell increment under hot state is unbalanced, with piston surface of contact irregular wear, finally causes engine scuffing, burn oil, abnormal sound, shortens engine life.
Model utility content
The purpose of this utility model is: overcome the defect that prior art exists, propose a kind of automobile engine cylinder-body, overcome the shortcoming on existing cylinder body, solve water inlet position irrational distribution, each cylinder barrel outer wall cooling water water flow velocity is inhomogeneous.
The purpose of this utility model realizes by following technical proposals:
A kind of V-type automobile engine cylinder-body, this cylinder body comprises that cylinder hole, left and right side hang face, V-type groove, front/rear end, respectively there is a water inlet, place the both sides of described cylinder body front-end face, cylinder hole left and right side is suspension face, V-type groove, in the middle of left and right side suspension face, is characterized in that: described water inlet diameter is 28 ㎜～32 ㎜.
As preferably, described water inlet diameter is 30 ㎜.
As preferably, described water inlet is positioned at central position, front-end face both sides.
As preferably, described cylinder body is cast by gray cast iron.
The beneficial effects of the utility model: the utility model V-type engine water inlet diameter is arranged on 28 ㎜～32 ㎜, can be effectively evenly flow and the flow velocity of the each cylinder barrel cooling water of reasonable distribution, can effectively solve the each cylinder barrel wall of the motor inhomogeneous problem of dispelling the heat.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model V-type automobile engine cylinder-body;
Mark in figure: 1-cylinder hole, 2-left and right side hang face, 3-V type groove, 4-front-end face, 5-water inlet.
Embodiment
below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Fig. 1 is the structural representation of the utility model V-type automobile engine cylinder-body, this cylinder body comprises that cylinder hole 1, left and right side hang face 2, V-type groove 3, front-end face 4, respectively there is a water inlet, place 5 both sides of described cylinder body front-end face 4, cylinder hole left and right side is suspension face 2, V-type groove 3 is in the middle of left and right side suspension face, and described water inlet 5 diameters are 30 ㎜, and water inlet 5 is positioned at front-end face 4 central positions, both sides, as preferably, described cylinder body is cast by gray cast iron.
Flow and the flow velocity of the affects cylinder barrel cooling water of the diameter of inlet hole 5, diameter is excessive or too small, capital makes each cylinder barrel outer wall cooling water water flow velocity inhomogeneous, cause the each cylinder barrel wall heat radiation of motor inhomogeneous, each cylinder barrel wall swell increment under hot state is unbalanced, finally cause engine scuffing, burn oil, abnormal sound, shorten engine life.Water inlet 5 diameters of the utility model V-type automobile engine cylinder-body are arranged on 28 ㎜～32 ㎜, can be effectively evenly flow and the flow velocity of the each cylinder barrel cooling water of reasonable distribution, can effectively solve the each cylinder barrel wall of the motor inhomogeneous problem of dispelling the heat.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (4)
