At present, put in the horizontal engine vent systems vertical, the traditional casting gas exhaust manifold of the many employings of gas exhaust manifold hot junction assembly, and connect the ternary catalyzing unit of back by flange, structure is not compact, needs assembly space big, and ternary catalyzing unit is far away apart from the engine chamber relief opening, cause the gas exhaust manifold thermal loss big, be unfavorable for the catalyst converter catalyzed conversion.The thickness of pipe wall of conventional cast gas exhaust manifold causes thermal loss excessive, influences the ternary catalyzing unit catalytic conversion efficiency of back.Gas exhaust manifold exit flow temperature reduces too much, at the engine start initial stage, can't guarantee the maximum discharge performance catalyst converter internal reaction temperature of present environmental requirement, make ternary catalyzing unit internal-response deficiency, catalytic conversion efficiency is lower, causes the car load discharge tail gas to be difficult to satisfy state 4, state's 5 emission standard requirements of national requirements for environmental protection.The inner wall roughness height of conventional cast gas exhaust manifold, coarse inwall cause that the back pressure of manifold increases, and increase the power loss of motor, are unfavorable for the lifting of engine performance.
The model utility content
The purpose of this utility model provides a kind of vertical special-purpose exhaust manifold assembly of horizontal engine of putting, and it is far away from engine exhaust port to solve existing ternary catalyzing unit, the problem that the gas exhaust manifold thermal loss is excessive.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of vertical special-purpose exhaust manifold assembly of horizontal engine of putting, comprise gas exhaust manifold and ternary catalyzing unit and the steam outlet pipe connected in turn, described gas exhaust manifold inlet end is provided with the air inlet adpting flange, and described steam outlet pipe outlet side is provided with the adpting flange of giving vent to anger; Described gas exhaust manifold is the exhaust duct that manifold lower shell body and manifold upper shell are welded into, and each branched pipe of described exhaust duct sidepiece setting is inserted on the air inlet adpting flange.
Preferably, described manifold lower shell body and manifold upper shell pass through mould compression moulding by resistant to elevated temperatures steel plate.
Preferably, lambda sensor joint before close ternary catalyzing unit end is provided with on described gas exhaust manifold is provided with the post oxygen sensor joint at described steam outlet pipe near the ternary catalyzing unit end.
Preferably, described gas exhaust manifold is provided with first support and second support that is used for fixing thermal shield.
The beneficial effects of the utility model: because described gas exhaust manifold is the exhaust duct that manifold upper shell and manifold lower shell body are welded into, each branched pipe of exhaust duct sidepiece setting is inserted on the air inlet adpting flange, engine exhaust collects in the exhaust duct of connecting each branched pipe and finishes, the distance of ternary catalyzing unit and engine exhaust port is shortened greatly, reduce the thermal loss on the gas exhaust manifold, improve catalyst converter catalytic conversion efficient, discharge tail gas is more cleaned, and this assembly structure compactness is convenient to arrange assembling.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
