Purification device capable of preventing influence of motor vibration on air-tightness of pipeline

Abstract

The invention discloses a purification device capable of preventing influence of motor vibration on the air-tightness of a pipeline. The purification device comprises an exhaust manifold, a catalyst, a connector, a flange and a fixed frame, wherein the connector comprises a sleeve head and a connecting pipe which are communicated with each other; the sleeve head is connected with the catalyst; the flange is provided with a plurality of plug holes; the nozzle of the exhaust manifold is correspondingly plugged into each plug hole; the flange is also provided with a plurality of threaded holes; and one end of the fixed frame is fixed to the sleeve head, and the other end of the fixed frame is provided with a through hole. By using the structure, the purification device has a rational structure and a relatively small size, and meanwhile, the entire exhaust device can be fixedly connected with a motor very well to prevent loosening of the exhaust manifold caused by vibration of the motor and guarantee the air-tightness.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a purification device capable of preventing motor vibration from affecting pipeline airtightness. Background technique [0002] Manifold is a pipeline structure used in automobile intake and exhaust systems, which can be divided into intake manifold and exhaust manifold. The intake manifold is located between the throttle valve and the engine intake valve. When the air enters the throttle valve and passes through the manifold buffer tube, the air flow paths begin to diverge, corresponding to the number of engine cylinders. For example, a four-cylinder engine has four channels. The five-cylinder engine corresponds to five channels, which introduce air into each cylinder separately. For a naturally aspirated engine, since the intake manifold is located behind the throttle valve, when the engine throttle opening is small, the cylinder cannot absorb enough air, which will cause ...

Problems solved by technology

[0004] The invention provides a purification device capable of avoiding motor vibration from affecting the airtightness of pipelines, and solves the problem that the structure of the previous purification device is not very reasonable, resulting in a relatively large volume. At the same time, since the entire exhaust device is connected to the motor, the vibration of the motor It is likely to cause the exhaust manifold to loosen, causing the problem of air leakage
