Label declaration in schematic diagram: 1, diesel engine body; 2, intake manifold; 3, intake manifold.
Embodiment
For understanding content of the present utility model further, by reference to the accompanying drawings the utility model is described in detail.
Composition graphs 1, a kind of S495 diesel engine suction tude modified node method of the present utility model, comprise diesel engine body 1, intake manifold 2 and intake manifold 3, intake manifold 2 is connected with diesel engine body 1 by intake manifold 3, diesel engine body 1 is provided with suction port, intake manifold 3 pipe orifice footpath 10-20mm larger than the suction port bore in diesel engine body 1, intake manifold 3 end is by matching with the suction port bore in diesel engine body 1 after arc transition, and the cross section of intake manifold 3 is circular or square.
Below in conjunction with embodiment, the utility model will be further described.
Embodiment 1
As shown in Figure 1, a kind of S495 diesel engine suction tude modified node method of the present embodiment, comprise diesel engine body 1, intake manifold 2 and intake manifold 3, intake manifold 2 is connected with diesel engine body 1 by intake manifold 3.Because the fuel consumption rate of suction tude to S495 diesel engine has considerable influence, and the turning round too urgent and there is the region of the abrupt change of cross-section of suction tude in prior art, cause larger flow resistance, the volumetric efficiency of intake duct is declined, the loss of air inlet middle pressure is risen, for solving the problem, the present embodiment devises a kind of new air feeder structure, and wherein the pipe orifice footpath of intake manifold 3 is greater than and is arranged on suction port bore in diesel engine body 1 and corresponding with intake manifold 3.Particularly, the intake manifold 3 pipe orifice footpath of the present embodiment is made into 10mm larger than the suction port bore in diesel engine body 1, adopts this modified node method, and the flow losses of air in suction tude reduce, and resistance reduces, and the volumetric efficiency of diesel engine is improved., by matching with the suction port bore in diesel engine body 1 after arc transition, be convenient to be tightly connected in intake manifold 3 end.The cross section of intake manifold 3 is circular or square, and specifically the cross section of intake manifold 3 is square in the present embodiment, can allow the more smooth and easy of air current flow; And intake manifold 3 adopts round-corner transition with the joint of intake manifold 2, the radius of fillet is 1/3rd sizes of intake manifold 3 radius, effectively reduce the resistance that air-flow runs into when flowing through this place, and then decrease the flow losses of air-flow when flowing through this place.In addition, the intake manifold 2 of the present embodiment and the inner and outer surface of intake manifold 3 are coated with wear resistant corrosion resistant layer, even if like this diesel engine works in comparatively rugged environment, intake manifold 2 and intake manifold 3 still can effectively work for a long time, can not be worn or corrode, extend the working life of this structure.
