Description
Technical field
The utility model relates to the vent systems of motor car engine, is specifically related to the exhaust manifold assembly of motor.
Background technique
Along with people are more and more stricter to automobile emissions standards to the pay attention to day by day and the country of environmental protection, require three-way catalytic converter ignition fast, solve during the cold starting because temperature is crossed the low problem that can't satisfy emission standard, this just requires the vent systems design catalyst converter that the time as far as possible moves forward to use the caloric receptivity less material simultaneously, and at present general be the tight coupling type exhaust manifold assembly that two punching presses, half shell is welded.But two halves shell welding type gas exhaust manifold is often because complex structure, it is higher that whole punching press causes material local reduction to lead, make the gas exhaust manifold insufficient strength, simultaneously because complex structure, also make robot welding inconvenience implement, anufacturability is bad, and it is not high to make efficient, and can produce harmful effect to product reliability.
Summary of the invention
The purpose of this utility model provides a kind of engine exhaust manifold assembly, and the function of integrated gas exhaust manifold and two component of catalyst converter satisfies the requirement of motor high standard discharging, and improves its anufacturability.
Exhaust manifold assembly described in the utility model comprises gas exhaust manifold part and catalyst converter part, the function of its integrated gas exhaust manifold and catalyst converter.Described gas exhaust manifold partly comprises air inlet flange disks, four bend pipe air flues and gathers air flue, the described air flue that gathers is formed by upper shell and lower shell body butt welding, one end of a bend pipe air flue on the wherein limit is connected with an end that gathers air flue, an end of three is connected with a side that gathers air flue respectively in addition, and the other end of four bend pipe air flues all is connected with air inlet flange disks.Described catalyst converter partly comprises packing casing, outlet end awl, outer pipe and outlet(discharge) flange dish, and the packing casing front end is connected with the other end that gathers air flue, and the rear end of packing casing is linked in sequence, and outlet end is bored, catalyst converter goes out pipe and outlet(discharge) flange dish.Said structure, owing to gather the unique arrangement structure of air flue, the catalyst converter part that moved forward does not reach the problem of emission request because of delivery temperature is low in the time of can effectively solving cold starting, satisfy the high standard emission request.In addition,, can't realize the manufacturing bottleneck of full robot welding when efficiently solving the assembly welding, improve manufacturing process and product, also improve reliability of products from manufacture view by adopting the design of half shell and bend pipe welding.
Further, the upper shell and the lower shell body that gather air flue use stainless steel materials to be stamped to form, since the relative cast iron of stainless steel manifold airway walls to approach about 10mm, the absorption heat is few, can guarantee the arrival ternary catalyzing unit front end that heat is fast as far as possible during engine start, make it reach initiation temperature as early as possible, do not reach the problem of emission request during with the solution cold starting owing to delivery temperature is low.
Described air inlet flange disks and outlet(discharge) flange dish are the punching type thin flange, to alleviate the weight of product.
As seen, the utility model is on the one hand owing to catalyst converter uses stainless steel materials and effectively reduces thermal loss near gas exhaust manifold while gas exhaust manifold, can satisfy the requirement of motor high standard discharging, anufacturability is good on the other hand, can either realize full robot welding, enhance productivity, can improve the reliability of product itself again.
