Technical field
The utility model relates to a kind of engine exhaust system assembly, especially relates to a kind of enmgine exhaust and ternary catalyzing unit hot junction assembly.
Background technique
Gas exhaust manifold and ternary catalyzing unit are very important parts in the engine exhaust system.Gas exhaust manifold is assemblied between engine cylinder-body and the vent systems, and its function is the waste gas behind each cylinder combustion of motor to be compiled and through vent systems and then enter in the air.Along with reaching its maturity of engine technology, motor itself reduces gradually for the space of performance boost, and the optimal design of gas exhaust manifold is having very big potentiality aspect the engine performance lifting.
At present, gas exhaust manifold mainly is divided into two classes, and a class is traditional founding type manifold, and its shortcoming has: the first, and pts wt is big, and tube wall is too thick, and thermal loss is too high, is unfavorable for the ignition of catalyst converter, is unfavorable for the control of Ou Si, Europe five emission requests; The second, casting gas exhaust manifold inner wall coarse, flow resistance is big, can cause higher engine power loss.Another kind of gas exhaust manifold is a stainless steel welding type gas exhaust manifold, and such manifold tube wall is thin, weight is lighter, and flow resistance is little, and thermal loss is little, and is favourable for the catalyst converter ignition.But mostly two class gas exhaust manifold structures are the waste gas behind each cylinder combustion of motor is directly converged to the inlet end of ternary catalyzing unit through each gas exhaust manifold, and then enter in the air through vent systems.Exhaust airstream behind its each cylinder combustion is interfered in the mutual disturbance of concourse, and it is big that the gas flow resistance becomes, and the power loss of motor on vent systems is bigger, influences the lifting of engine performance.
The model utility content
The purpose of this utility model provides a kind of enmgine exhaust and ternary catalytic converter assembly, and the problem that the gas flow resistance is big is interfered seriously in the mutual disturbance of exhaust airstream that solves each gas exhaust manifold concourse.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of enmgine exhaust and ternary catalytic converter assembly comprise gas exhaust manifold group and ternary catalyzing unit; Also comprise one group of influx pipe connecting gas exhaust manifold group and ternary catalyzing unit, described influx pipe is shaped as " Y " font, and the outlet side of described influx pipe inlet end and two gas exhaust manifolds is connected, and the inlet end of influx pipe outlet side and ternary catalyzing unit is connected.
Described ternary catalyzing unit comprises front cone and ternary catalyzing unit body and back cone, and the front cone of described influx pipe lower end and ternary catalyzing unit is connected.
Described gas exhaust manifold, influx pipe, front cone, back cone form by the corrosion resistant plate impact briquetting.
Described gas exhaust manifold, influx pipe, front cone, ternary catalyzing unit body, back cone are in turn by being welded to connect.
The beneficial effects of the utility model: owing between gas exhaust manifold and ternary catalyzing unit, set up the influx pipe of a plurality of " Y " font, make existing a plurality of gas exhaust manifold directly merge in the ternary catalyzing unit inlet end, become wherein that two gas exhaust manifolds converge to earlier in the influx pipe, each influx pipe converges to the ternary catalyzing unit inlet end more then.Make the mutual disturbance of exhaust airstream of its each stainless exhaust manifold and influx pipe concourse interfere less, the gas flow resistance is little, improved the uniformity coefficient of ternary catalyzing unit, reduced hot junction exhaust pressure loss simultaneously, reduce the power loss of motor on vent systems, and then improved the performance of motor.
