Abstract
The utility model provides an engine intake manifold and cylinder head integrated configuration, include the intake duct of air inlet, the gas outlet of cylinder head inboard, the interior intercommunication air inlet of cylinder head and the gas outlet in cylinder head, the cylinder head outside, its air inlet lies in the upper portion of cylinder head, and the intake duct section of admitting air is upwards bent, feeds through the air inlet on cylinder head upper portion, connects the mouth of pipe that admits air on the air inlet, and the short straight tube of the mouth of pipe for taking flange that admit air is at the upper portion and the air inlet sealing connection of cylinder head. The intake duct correspond air inlet department and have the outer chamber of expanding. The hole passed through on fastening bolt and the flange face of the short straight tube of taking flange of the mouth of pipe that admits air be connected with the air inlet on cylinder head upper portion, have sealed the pad between flange and the air inlet. The utility model discloses the transverse dimension of engine has been reduced effectively for the engine can be installed in the vehicle smoothly, material cost reduces to some extent simultaneously. Can be applied to various engines, including diesel engine, gasoline engine and gas engine etc..
Description
Technical field
This utility model relates to a kind of engine air inlet tube and cylinder head combinative structure.Belong to automobile engine/gas handling system field.
Background technology
At present, engine air inlet tube major part is individually designed, and air inlet pipe is generally bend pipe, is arranged on the side of engine cylinder cap.The design of this structure makes the lateral dimension of electromotor relatively greatly, and inconvenience electromotor is installed in vehicle；Non-ferrous metal aluminum manufacture commonly used by air inlet pipe material simultaneously, and manufacturing cost is higher than ferrous metal.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of engine air inlet tube proposed and cylinder head combinative structure.This combinative structure can reduce the lateral dimension of electromotor effectively so that electromotor can successfully be installed in vehicle；It is simultaneously fabricated into and originally decreases.
The technical solution of the utility model: engine air inlet tube of the present utility model connects the air intake duct of air inlet and gas outlet include the air inlet outside cylinder head, cylinder head, the gas outlet inside cylinder head, cylinder head with cylinder head combinative structure in, its air inlet is positioned at the top of cylinder head, air intake duct air inlet section is bent up, connection cylinder upper part of the cover air inlet, air inlet connects the air inlet mouth of pipe, the air inlet mouth of pipe is the short straight tube of band adpting flange, is tightly connected with air inlet on the top of cylinder head.
Chamber is extended out at described air intake duct correspondence air inlet.
The short straight tube of the band adpting flange of the described air inlet mouth of pipe is connected with cylinder upper part of the cover air inlet by the hole in fastening bolt and flange face, has sealing gasket between adpting flange and air inlet.
This utility model technique effect: this utility model efficiently reduces the lateral dimension of electromotor so that electromotor can successfully be installed in vehicle；Material cost decreases simultaneously.Can be applicable to various electromotor, including diesel engine, gasoline engine and gas engine etc..
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described.
Fig. 1 is the structural representation of a kind of engine air inlet tube of the present utility model and cylinder head combinative structure: as shown in the figure: this utility model connects the air intake duct 4 of air inlet 2 and gas outlet 3 in including the air inlet 2 outside cylinder head 1, cylinder head, the gas outlet 3 inside cylinder head, cylinder head, its air inlet 2 is positioned at the top of cylinder head 1, air intake duct 4 air inlet section is bent up, the air inlet 2 on connection cylinder head 1 top, air inlet 2 connects the air inlet mouth of pipe 5, the air inlet mouth of pipe 5 is the short straight tube of band adpting flange, is tightly connected with air inlet 2 on the top of cylinder head 1.
Extend out chamber 4a at the corresponding air inlet 2 of described air intake duct 4, extend out chamber 4a and be reduced the effect of intake resistance.Its air intake duct 4 air inlet section is bent up part and extends out chamber 4a and be cast in cylinder head 4, instead of original intake elbow, forms a complete inlet chamber with air intake duct 4, it is achieved the function of engine air inlet tube.
The short straight tube of the band adpting flange of the described air inlet mouth of pipe 5 is connected with the air inlet 2 on cylinder head 1 top by the hole in fastening bolt 6 and flange face, has sealing gasket 7, prevent air inlet pipe from leaking gas between adpting flange and air inlet 2.
The described air inlet mouth of pipe 5 and sealing gasket 7 are parts for engine air inlet tube, with the air intake duct 4 in cylinder head 1 and extend out chamber 4a and collectively form inlet chamber.
Described fastening bolt 6 is hexagon flange bolt, and quantity is 14.
This utility model is applicable to 7 liters and 9 liters of electromotors.
Core of the present utility model is that engine intake manifold is combined with air intake duct, is cast in cylinder head, and as the major part of air inlet pipe.Therefore, every offer by cylinder head casts inlet manifold and air intake duct combination, belongs to protection domain of the present utility model.
