Description
Technical field
The invention belongs to technical field of engines, specifically the admission manifold branch structure of motor.
Background technique
Engine intake manifold is the parts for air being imported to each cylinder, and the working efficiency to motor, fuel consume, power output performance play vital effect.Multiple air intake branches that existing inlet manifold assembly is generally connected by pressure stabilizing cavity and with pressure stabilizing cavity form, and the corresponding intake duct that each air intake branch covers with engine cylinder is connected.But because each arm distortion mode of intake manifold is different with length, cause the each cylinder homogeneity of motor poor, and the pressure loss that air enters cylinder by air intake branch is very large, has directly affected the working efficiency of motor, and is unfavorable for processing.Therefore, intake manifold reasonable in design, the inflation homogeneity of raising intake manifold, the reduction pressure loss, raising engine operation efficiency, be that those skilled in the art have problem to be solved.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, the engine intake manifold assembly of superior performance.
The alleged problem of the present invention realizes with following technical proposals:
An inlet manifold assembly for motor, comprises the pressure-stabilizing bin being connected with engine air filter and the intake manifold being connected with engine cylinder cover.Described intake manifold is the intake manifold of a single channel, the suction port of described intake manifold connects pressure-stabilizing bin, be provided with an isosceles tri-prismoid in suction port center, this isosceles tri-prismoid connects two planes up and down of intake manifold, and the drift angle of cylinder is just to airintake direction; The air outlet of described intake manifold is corresponding with the suction port of engine cylinder cover, is provided with the flange being connected with engine cylinder cover on air outlet.
Intake manifold of the present invention has been saved traditional admission manifold branch structure Zhong Ge branch air intake branch, uses multiple air intake branch air inlets in the intake manifold replace traditional structural of single gas-entered passageway special construction, and uses single air supply opening to replace original multiple air supply openings.
Compared to the prior art, the present invention has the following advantages:
1, structure of the present invention has been saved each air intake branch compared with conventional construction, adopt single gas-entered passageway air inlet and single air supply opening air feed, increase air inflow, and make air inlet more abundant, promoted intake efficiency, promoted the working efficiency of motor, and designs simplification, volume reduces, and has reduced cost, is convenient to the layout of complete machine and the assembling of component.
2, adopt isosceles tri-prismoid to divide gas, for three cylinder engine, can make each cylinder air inlet homogeneous, improved the homogeneity of air inlet, contribute to promote power performance and the fuel efficiency of motor.
Accompanying drawing explanation
Fig. 1 is the plan view of structure of the present invention;
Fig. 2 is the flanged (FLGD) structural drawing in air outlet;
Fig. 3 is side view of the present invention;
Fig. 4 is the orthogonal view that the intake manifold at tri-prismoid position is installed.
In figure: 1 is intake manifold pressure-stabilizing bin, and 1-1 is pressure-stabilizing bin suction port, and 1-2 is pressure-stabilizing bin air outlet; 2 is isosceles tri-prismoid; 3 is described intake manifold; 4 is air outlet; 5 is four flanges that are connected with motor.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, to Fig. 4, this inlet manifold assembly comprises a pressure-stabilizing bin 1 and an intake manifold 3, and intake manifold is the intake manifold of a single channel.Pressure-stabilizing bin suction port 1-1 connects air-strainer, pressure-stabilizing bin air outlet 1-2 connects the suction port of the intake manifold 3 of single channel, intake manifold 3 the other ends are single air outlets 4 corresponding to three intake ducts that cover with engine cylinder, air outlet 4 connecting engine cylinder caps, are provided with four flanges that are connected with engine cylinder cover 5 on it.Gas enters pressure-stabilizing bin 1 by air-strainer, and by entering intake manifold 3 after pressure-stabilizing bin 1 voltage stabilizing, the gas by intake manifold 3, via intake manifold air outlet 4, enters the each cylinder of motor.
In this structure, adopt the intake manifold of single gas-entered passageway, suction port is increased, the gas flow that enters intake manifold from pressure-stabilizing bin air outlet 1-2 is increased, and while adopting single gas-entered passageway to avoid engine charge, there is portion gas to remain in the situation in other air intake branches, make air inlet more complete.Single channel and single air outlet have been reduced gas and have been entered after manifold and the gas collisions of manifold wall and manifold air supply opening, can reduce the pressure loss of gas.
And, being provided with the isosceles tri-prismoid 2 of the upper and lower plane 3-1 of a connection manifold and 3-2 in the suction port center of intake manifold 3, this isosceles tri-prismoid is hollow, and there is no bottom surface and end face, i.e. up/down perforation.The drift angle of isosceles tri-prismoid 2 is just to airintake direction.Due to the left and right sides, air outlet (corresponding motor one, three cylinders) from suction port away from, in the middle of air outlet, (corresponding motor two cylinder) is from the direct air inlet of suction port, air inlet distance is short, have higher intake efficiency, by isosceles tri-prismoid 2 being set at suction port place, bootable institute air inlet body more flows into along intake manifold inwall, can increase motor one, the air inflow of three cylinders, dwindle the air inlet difference with motor two cylinder, by this special construction of isosceles tri-prismoid 2, guarantee the uniformity of each cylinder intake, improve the working efficiency of motor.
