AI Technical Summary
The prior art When the catalyst is arranged vertically on the cylinder side, the production cost is high and the intake pipe welding process is cumbersome, so it cannot be applied to projects where the catalyst is closer to the intake pipe.
The integrated retaining ring structure is used as the catalyst support and is fixed inside the cylinder, which can not only support the catalyst to prevent twitching, but also prevent the cylinder deformation caused by welding, and simplify the processing technology.
It reduces the overall cost and is suitable for compact structures. The retaining ring almost does not intercept the airflow, reduces the back pressure and improves the power performance of the entire vehicle.
