Abstract

The utility model is related to the engine cylinder head systems that a kind of machine adds water jacket, including:Cylinder cap, cylinder cover water jacket, cylinder body and cylinder body water jacket, the end face center position of cylinder cap is provided with exhaust valve seat and suction valve cone, multiple cylinder cap water holes are provided on the end face of cylinder cap, positioned at exhaust valve seat and suction valve cone surrounding, organic water inlet is set on cylinder cap end face, cylinder cap is internally provided with cylinder cover water jacket, cylinder cover water jacket is connected to machine water inlet and cylinder cap water hole, it is provided with cylinder body below the cylinder cap, head gasket is provided between cylinder cap and cylinder body, cylinder body water jacket is provided in cylinder body, cylinder body water jacket is connected with the cylinder body water hole on cylinder upper end face.Organic water inlet, which is arranged, in the utility model on cylinder cap end face makes cylinder body water jacket be connected to cylinder cover water jacket, it solves high temperature at exhaust valve seat and causes reduced service life, since degree of asking reduces at exhaust valve seat, to reduce the wall thickness at exhaust valve seat in processing technology, achieve the purpose that save material.

Description

A kind of machine adds the engine cylinder head system of water jacket
Technical field
The utility model is related to the engine cylinder head systems that technical field of internal combustion engines more particularly to a kind of machine add water jacket.
Background technology
It requires to be continuously improved recently as engine power and oil consumption, engine reinforcing degree is higher and higher, especially The exploitation of direct fuel-injection engine causes engine part to require intensity, thermic load also higher and higher.
The exhaust valve seat of existing engine cylinder head system, is washed away by high-temperature fuel gas, while by valve during valve switch Slap and sliding friction, working environment is severe, causes the reduction of service life, and traditional cylinder cover design is to use casting water jacket pair Combustion chamber carries out whole cooling, and flow of cooling water is also irregular, and cylinder cap different parts temperature is uneven
Utility model content
The purpose of this utility model is to provide the engine cylinder head system that a kind of machine adds water jacket, reduces the temperature of cylinder cap and cylinder body Degree, extends service life.
Utility model technical solution:
A kind of machine adds the engine cylinder head system of water jacket, including:Cylinder cap water hole, machine water inlet, cylinder cap, cylinder cover water jacket, cylinder body and Cylinder body water jacket,
The end face center position of the cylinder cap is provided with exhaust valve seat and suction valve cone;
It is provided with multiple cylinder cap water holes on the end face of the cylinder cap, is located at exhaust valve seat and suction valve cone surrounding, head side Organic water inlet is set on face;
The cylinder cap is internally provided with cylinder cover water jacket, and cylinder cover water jacket is connected to machine water inlet and cylinder cap water hole;
It is provided with cylinder body below the cylinder cap, head gasket is provided between cylinder cap and cylinder body;
Cylinder body water jacket is provided in the cylinder body, cylinder body water jacket is connected with the cylinder body water hole on cylinder upper end face, cylinder body The cylinder body water hole of upper surface is connected with the cylinder cap water hole of cylinder cap end face and machine water inlet;
The machine water inlet is located at below the end face center line of cylinder cap.
Further, the machine water inlet is inclined water hole, and machine water inlet is angled 30-60 degree with cylinder cap end face.
The utility model has the advantages that the prior art:The utility model is arranged organic on cylinder cap end face Water inlet makes cylinder body water jacket be connected to cylinder cover water jacket, solves at exhaust valve seat that high temperature causes reduced service life, due to exhaust Degree of asking reduces at gate seat, to reduce the wall thickness at exhaust valve seat in processing technology, achievees the purpose that save material.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is cylinder cap and cylinder body connection relationship diagram.
Specific implementation mode
The utility model is described in detail below with reference to attached drawing.
Embodiment one:A kind of machine adds the engine cylinder head system of water jacket, including:Cylinder cap water hole 3, machine water inlet 4, cylinder cap 5, cylinder cap Water jacket 6, cylinder body 7 and cylinder body water jacket 8,
The end face center position of the cylinder cap 5 is provided with exhaust valve seat 2 and suction valve cone 1;
It is provided with multiple cylinder cap water holes 3 on the end face of the cylinder cap 5, is located at 1 surrounding of exhaust valve seat 2 and suction valve cone, cylinder Organic water inlet 4 is arranged on 5 end face in lid;
The cylinder cap 5 is internally provided with cylinder cover water jacket 6, and cylinder cover water jacket 6 is connected to machine water inlet 4 and cylinder cap water hole 3;
5 lower section of the cylinder cap is provided with cylinder body 7, and head gasket is provided between cylinder cap 5 and cylinder body 7;
Cylinder body water jacket 8 is provided in the cylinder body 7, cylinder body water jacket 8 is connected with the cylinder body water hole on 7 upper surface of cylinder body, The cylinder body water hole of 7 upper surface of cylinder body is connected with the cylinder cap water hole 3 of 5 end face of cylinder cap and machine water inlet 4;
The machine water inlet 4 is located at below the end face center line of cylinder cap 5.
Embodiment two:The machine water inlet 4 is inclined water hole, and machine water inlet 4 is angled 30-60 with 5 end face of cylinder cap Degree.So set, because machine water inlet 4 be inclined water hole, 5 end face of cylinder cap carry out integrally casting, be it is impossible, So needing the machining in progress later stage.
