Problems solved by technology

[0004] The invention provides a three-way catalytic converter, an engine exhaust assembly and an automobile. By adopting an intake flange with blades and an intake pipe matched therewith, the air intake end of the three-way catalytic converter is adjusted from the overall structure. Optimization can not only solve the problem that the intake pipe and three-way catalytic converter shell cannot be welded and matched due to the smaller layout space of the three-way catalytic converter, but also improve the uniformity coefficient of the air flow to meet the high-performance design requirements

Abstract

The invention provides a three-way catalytic converter, an engine exhaust assembly and an automobile. By adopting an intake flange with blades and an intake pipe matched with it, the intake end of the three-way catalytic converter is analyzed from the overall structure. The optimization can not only solve the problem that the intake pipe and the three-way catalytic converter casing cannot be welded and matched due to the smaller layout space of the three-way catalytic converter, but also can improve the uniformity coefficient of the airflow and meet the high-performance design requirements.

Description

technical field [0001] The invention relates to an automobile engine exhaust system, in particular to a three-way catalytic converter, an engine exhaust assembly and an automobile. Background technique [0002] The three-way catalytic converter is generally located between the supercharger and the muffler, and is generally close to the cylinder head of the automobile engine. In order to ensure the low back pressure of the catalytic converter and meet the performance requirements of the engine, a uniformity coefficient as high as possible is required, but the layout space is limited, and the uniformity coefficient of the design requirements is often not achieved. At this time, it is necessary to design a three-way catalytic converter structure to improve the uniformity coefficient. At present, the commonly used three-way catalyst structure is as follows: figure 1 As shown, the common intake flange 31 , the common air passage 32 , and the three-way catalytic converter housin...
