Go up the catalyst converter front end housing of clam shell and lower clam shell welding together formation " X " type. The steering current is come to the clam shell structure of " X " the type of utilization, has avoided the pressure oscillation for engine performance is more stable. Arrange by connecting gradually the catalyst converter assembly close coupling that together catalyst converter front end housing, catalyst converter body, catalyst converter rear end cap constitute, very big improvement the combustion initiation temperature of catalyst, emission level when having promoted the cold start.
Description
Technical field
The utility model relates to the exhaust manifold device of motor, particularly one longitudinal motor close coupling exhaust manifold assembly.
Background technique
Energy-saving and environmental protection, efficiently these characteristics become the target that Automobile Enterprises is competitively pursued, and gas exhaust manifold part plays an important role for realizing above-mentioned target, for the automobile that motor is longitudinally arranged, and good gas exhaust manifold design especially difficulty.Mostly existing longitudinal enmgine exhaust is no tight coupling form, and four outlet pipes are pooled to same passage simultaneously, catalyst temperature low and impact discharge when such design causes vehicle cold start-up, the air flue layout of four-in-one can cause the bad phenomenon such as interference in air flow and pressure surge simultaneously, affects engine performance.
Summary of the invention
The utility model proposes a kind of longitudinal motor close coupling exhaust manifold assembly, its structure is simple, be convenient to processing, easy for installation.
The technological scheme that the utility model adopts is: a kind of longitudinal motor close coupling exhaust manifold assembly, the the first bend pipe air flue comprising suction flange and fit together with suction flange, second bend pipe air flue, 3rd bend pipe air flue, 4th bend pipe air flue and outlet(discharge) flange, its technological points is: also comprise catalytic converter assembly, described catalytic converter assembly is by the catalyst converter front cover be connected in turn, catalyst converter body, catalyst converter rear end cover forms, catalyst converter front cover is by the upper clam shell with the first recess and the second recess, lower clam shell with the 3rd recess and the 4th recess forms, first recess of upper clam shell and the 3rd recess of lower clam shell are oppositely arranged, form first mouth, second recess of upper clam shell and the 4th recess of lower clam shell are oppositely arranged, form second mouth, upper clam shell is relative with lower clam shell to be welded together.
First bend pipe air flue and the 3rd bend pipe gas are plugged on first mouth, and the second bend pipe air flue and the 4th bend pipe air flue are plugged in second mouth, catalyst converter rear end cover connection outlet flange.
As a kind of preferred version of the present utility model, upper clam shell and lower clam shell are welded together to form the catalyst converter front cover of X-type.
As further preferred version of the present utility model, the X point of intersection place on X-type catalyst converter front cover is provided with lambda sensor.
The beneficial effects of the utility model and advantage are: this longitudinal motor close coupling exhaust manifold assembly, according to firing order, 4 bend pipe air flue intervals are arranged, first bend pipe air flue and the 3rd bend pipe gas are plugged on first mouth, second bend pipe air flue and the 4th bend pipe air flue are plugged in second mouth, catalyst converter rear end cover connection outlet flange, the air passage structure of this 4-2-1 ensures that each cylinder exhaust stream does not interfere with each other, and reduces pumping loss, improves the performance of motor.Upper clam shell and lower clam shell are welded together to form the catalyst converter front cover of " X " type.The clam shell design of " X " type of utilization guides air-flow, avoids pressure surge, makes engine performance more stable.X point of intersection place on X-type catalyst converter front cover is provided with lambda sensor.This lambda sensor position is arranged so that the identification of each cylinder exhaust signal is more accurate, effectively reduces oil consumption.The catalytic converter assembly close coupling be made up of the catalyst converter front cover be connected in turn, catalyst converter body, catalyst converter rear end cover is arranged, greatly improves the initiation temperature of catalyzer, improves emission level during cold start-up.
