Abstract
The utility model discloses a naturally, waste pipe assembly of breathing in, include admit air flange, return bend air flue, three way catalyst converter, outlet duct and the ring flange of giving vent to anger, it is provided with the inlet end awl to give vent to anger at the return bend air flue between end and the three way catalyst converter inlet end, and the spliced eye has been seted up to inlet end awl front end, and the edge of spliced eye forms annular first welding limit, and the return bend air flue is given vent to anger to hold and is inserted in the spliced eye, through first welding limit welded connection, inlet end awl rear end is provided with and is annular second welding limit, and the three way catalyst converter inlet end inserts inlet end awl rear end is through second welding limit welded connection. The utility model discloses can simplify the welding process process of exhaust manifold assembly air flue.
Description
Technical field
The utility model relates to automobile component, more specifically to a kind of outlet pipe assembly of naturally aspirated engine.
Background technique
The effect of engine exhaust manifold assembly is the waste gas collecting each cylinder of motor, avoids the exhaust between each cylinder mutually to disturb as far as possible, makes waste gas safety and discharges motor completely as much as possible.Trend and the structural design of gas exhaust manifold are extremely important, while meeting the power economy performance of motor, simplify the machining process of product as far as possible.
At present, in engine exhaust system, stainless exhaust manifold assembly air flue adopts two half-shell air flues mostly, and also some adopts stainless bend pipe to add two halves shell combined type air flue.Two half-shell air flues adopt both sides welding, and welding procedure is complicated, sometimes cannot solve the problem of Totally robotic welding when assembly welds.Stainless bend pipe adds two halves shell combined type air flue, substantially solves the problem of Totally robotic welding when assembly welds, but the welding between two halves shell still exists welding insufficient space problem.The two halves shell of two kinds of air flue modes all adopts both sides to weld, and welding procedure is complicated, and stock utilization is lower, and therefore cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of outlet pipe assembly of naturally aspirated engine, and it in limited arrangement space, can be arranged under meeting the prerequisite of engine power economic performance requirement, simplify the welding procedure of exhaust manifold assembly air flue.
The outlet pipe assembly of naturally aspirated engine described in the utility model, comprise inlet flange, bend pipe air flue, ternary catalyzing unit, steam outlet pipe and flange plate of giving vent to anger, the inlet end of bend pipe air flue is connected with inlet flange, the outlet side of bend pipe air flue is communicated with the inlet end of ternary catalyzing unit, the outlet side of ternary catalyzing unit is communicated with the inlet end of steam outlet pipe, the outlet side of steam outlet pipe is connected with flange plate of giving vent to anger, air inlet end cone is provided with between bend pipe air flue outlet side and ternary catalyzing unit inlet end, air inlet end cone is the large taper in little rear end, front end, air inlet end cone front end offers spliced eye, the edge of spliced eye forms the first welding edge of ring-type, bend pipe air flue outlet side is inserted in spliced eye, be welded to connect by the first welding edge, air inlet end cone rear end is provided with ringwise second welding edge, and ternary catalyzing unit inlet end inserts described air inlet end cone rear end, is welded to connect by the second welding edge.
Further, described spliced eye, in " 8 " font, can weld two bend pipe air flues simultaneously.
Further, described air inlet end cone is by stainless steel materials impact briquetting.
Further, between the outlet side and the inlet end of steam outlet pipe of ternary catalyzing unit, be provided with air outlet end cone, air outlet end cone is the little taper in large rear end, front end, and ternary catalyzing unit outlet side is welded with air outlet end cone front end, and air outlet end cone rear end is welded with steam outlet pipe inlet end.
The outlet pipe assembly of naturally aspirated engine described in the utility model, be connected with bend pipe air flue by the first welding edge, be connected with ternary catalyzing unit by the second welding edge, first, second welding edge is monolateral welding, this structure and two half-shell air flues or stainless bend pipe add two halves shell combined type air flue and compare, without half shell welding step, welding procedure more simplifies, can avoid because welding the product reliability risk brought simultaneously, whole welding process all adopts robot welding, improve manufacturing efficiency, conformity of production and stock utilization, save cost.
