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 catalyst, an engine exhaust assembly and an automobile. According to the three-way catalyst, the engine exhaust assembly and the automobile, the air inlet end of thethree-way catalyst is optimized from the overall structure by adopting an air inlet flange with blades and an air inlet pipeline matched with the air inlet flange, the problem that an air inlet pipeline and a three-way catalyst shell cannot be welded and matched with each other due to the fact that the arrangement space of a three-way catalyst becomes small can be solved, in addition, the uniformity coefficient of airflow can be increased, and the high-performance design requirement is met.

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, the uniformity coefficient as high as possible is required, but the layout space is limited, and the uniformity coefficient required by the design is often not achieved. At this time, it is necessary to design a three-way catalytic converter structure to improve the uniformity coefficient. The commonly used three-way catalytic converter structure is as follows: figure 1 As shown, common air intake flange 31, common air duct 32, and three-way catalytic converter housing 303, wherein o...
