Abstract

The utility model relates to a semi-shell-type exhaust branch pipe. The semi-shell-type exhaust branch pipe is in an overall-symmetric type and comprises an air inlet flange, an air outlet flange and exhaust branch pipe bodies which connect the two flanges. The air outlet flange is at least provided with two air outlets. The exhaust branch pipe bodies comprise at least two air channels. The air channels comprise four connecting pipes and two semi-shell-type bend pipes, wherein the four connecting pipes are connected with air inlets of the air inlet flange, and the two semi-shell-type bend pipes are connected with the four connecting pipes. After respectively and independently converged, the semi-shell-type bend pipes are connected with the air outlets of the air outlet flange. By the adoption of the processing mode of the combination of the connecting pipes and the semi-shell-type bend pipes, the exhaust branch pipe is compact in structure, the strict spatial arrangement requirements are met, and meanwhile the semi-shell-type exhaust branch pipe has the advantages of being high and hot in load, high in vibration strength, little in leakage amount and the like. Meanwhile, the lengths of the exhaust branch pipe bodies in the same air channel are similar, the exhaust is more even, the speed difference and the pressure loss are smaller, emission of an engine is reduced, and the power performance of the engine is improved.

Description

The half-shell gas exhaust manifold

Background technique
Gas exhaust manifold is one of parts of motor most critical, and the high temperature gas flow that produces during engine operation is discharged through gas exhaust manifold.in the engine exhaust field, gas exhaust manifold concerns the motor overall performance, component are arranged, and car load engine compartment design, emission standard etc., but due to narrow and small engine nacelle environment, make the spatial structure of gas exhaust manifold very complicated, the gas exhaust manifold of traditional non-half-shell bend pipe structure, be difficult to meeting spatial arrangement requirement and explained hereafter requirement, simultaneously due to gas exhaust manifold continuous firing under worst hot case, the working heat load is large, ocsillator strenght is high, working environment is extremely abominable, the gas exhaust manifold of traditional non-half-shell bend pipe structure also is difficult to satisfy the user can the handling and more and more higher requirement of travelling comfort to automobile.
The model utility content
The purpose of this utility model is to provide a kind of half-shell gas exhaust manifold that is mainly used in the naturally aspirated engine vent systems, it adopts the stainless steel material manufacturing, not only can work under, ocsillator strenght is high, alternating hot and cold impacts working environment large in heat load, when satisfying the requirement of gas exhaust manifold space arrangement requirement and explained hereafter, also satisfy power character and the emission request of motor.
The technical solution adopted in the utility model is: the half-shell gas exhaust manifold, comprise inlet flange, give vent to anger flange and the exhaust branch pipe that is connected two flanges, and inlet flange is provided with four inlet holes, it is characterized in that:
The described flange of giving vent to anger is provided with two air outlet holes at least, i.e. the first air outlet hole and the second air outlet hole;
Described exhaust branch pipe comprises at least two air flues, i.e. the first air flue and the second air flue, wherein
The first air flue comprises two the first connecting tubes that are connected with the 4th inlet hole with the first inlet hole, with the first half-shell bend pipe that is connected with the first connecting tube outlet, and described the first half-shell bend pipe give vent to anger the first air outlet hole on flange of rear connection that confluxes;
The second air flue comprises two the second connecting tubes that are connected with the 3rd inlet hole with the second inlet hole, with the second half-shell bend pipe that is connected with the second connecting tube outlet, and described the second half-shell bend pipe give vent to anger the second air outlet hole on flange of rear connection that confluxes;
Described exhaust branch pipe is the integrated symmetric formula.
Preferably, the suction port axis of described the first connecting tube and the second connecting tube is perpendicular to inlet flange.
Preferably, the air outlet axis of described the first half-shell bend pipe and the second half-shell bend pipe is perpendicular to the flange of giving vent to anger.
Preferably, described the first connecting tube, the second connecting tube, the first half-shell bend pipe and the second half-shell bend pipe adopt the stainless steel manufacturing.
The beneficial effects of the utility model are: the technology mode that adopts connecting tube and half-shell bend pipe to combine, make the gas exhaust manifold manifold structure compact, not only satisfy strict space arrangement requirement, have simultaneously the advantages such as high heat load, high ocsillator strenght, leakage rate are few, and the exhaust branch pipe length of same air flue is close, makes exhaust more even, and the speed difference opposite sex and the pressure loss are less, reduce the discharging of motor, improved the power character of motor.
