Abstract
The utility model provides a three-way catalytic converter assembly of an automobile engine, which comprises an air inlet flange, an air inlet end cap, a catalytic converter shell, an outlet end cap, an outlet pipe and an outlet flange welded in sequence. The air inlet end cap is divided into a punch-formed upper shell and a punch-formed lower shell along the length direction, the upper shell and the lower shell are butt-welded, one end of the air inlet end cap is welded with the air inlet flange, and the other end of the air inlet end cap is welded with the catalytic converter shell. Since the air inlet end cap is divided into the punch-formed upper shell and the punch-formed lower shell along the length direction, and the upper shell and the lower shell are butt-welded into a whole, the bending shape of each part can conveniently selected according to needs of the assembly space. Compared with the air inlet end cap with an overall structure, the utility model eliminates the forming difficulty. Moreover, the utility model can avoid the installation tool within the limited space, thereby solving the problem of difficult assembly of the three-way catalytic converter assembly and the turbocharger.
Description
Technical field
The utility model relates to the three-way catalytic converter structure of automobile.
Background technique
Along with people are more and more higher and environment more and more paid attention to the requirement of engine consumption, increasing motor has adopted turbosupercharger and ternary catalyzing unit has been installed to reduce oil consumption and to improve discharging on vent systems.At present the ternary catalyzing unit of motor car engine mainly by ternary catalyzing unit inlet flange, suction tude, air inlet end cap, middle casing, the end cap of giving vent to anger, steam outlet pipe and outlet(discharge) flange successively by being welded, and owing to be subjected to the restriction in engine compartment space, its suction tude generally designs shortlyer, be difficult in the bolt pneumatic gun that adopts when assembling the time is avoided ternary catalyzing unit and is connected with pressurized machine behind the bending, cause the assembly technology between ternary catalyzing unit and the turbosupercharger to seem very difficult.
Summary of the invention
The purpose of this utility model is to solve in limited space the problem of three-way catalytic converter assembly and turbosupercharger assembling difficulty, proposes a kind of motor car engine ternary catalytic converter assembly that improves structure.
The technical solution of the utility model is as follows:
A kind of motor car engine three-way catalytic converter assembly, its by air inlet flange disks, air inlet end cap, catalyst converter housing, outlet end cap, steam outlet pipe and outlet(discharge) flange successively by being welded, cover at inlet end the lambda sensor seat is installed, the post oxygen sensor seat is installed on steam outlet pipe.Wherein said air inlet end cap is divided into stamping forming upper shell and lower shell body two-part from length direction, and upper shell and lower shell body two-part are to welded together, and an end and air inlet flange disc weld, the other end and the welding of catalyst converter housing.This structure is divided into stamping forming upper shell and the butt welding of lower shell body two-part is assembled into one with the air inlet end cap from length direction, can make things convenient for like this its needs according to assembly space choose each to curved shape, with respect to integrally-built air inlet end cap, the difficulty that does not have moulding, can in limited space, avoid setting tool, solve the problem of three-way catalytic converter assembly and turbosupercharger assembling difficulty.
In order to satisfy three-way catalytic converter assembly and turbosupercharger assembling needs better, preferably the air inlet end cap is designed on two intersecting planes, be the continuous bend state, form special-shaped shape.
Description of drawings
