Abstract

This invention discloses a catalytic converter exhaust pipe installation of removable structure for the exhaust pipe segmental, one section of which is connected with the engine, the other one with the muffler extinguishers, and they are fixed on the vehicle chassis. Segmental exhaust pipe on the adjacent side is fixed with catalytic converters used in the connector, one connecting level-hole with large-diameter pipe is put in a fixed link, catalytic converters installed in the casing at the height limit and within the hole the hole shoulder, another connector to the hole with step nut sets, the stage-hole path in space with another cut exhaust pipe, nut sets stage large diameter hole in a ring-sealed trap in the exhaust pipe , nut sets the stage-hole large-diameter casing installed in the thread and thread with nut sets of clamping ring withstood a catalytic converter will be sealed and catalytic converters in the positioning of the casing. It can make catalytic converters easily fixed in the exhaust pipe, and the demolition, the replacement is very convenient. It is good at sealing and looks nice.

Description

technical field

[0001] The invention relates to an exhaust muffler structure of a motor vehicle, in particular to a detachable installation structure of an exhaust pipe catalytic converter. Background technique

[0002] The function of the exhaust muffler of a motor vehicle is to discharge the exhaust gas of the engine into the atmosphere, reduce the noise and temperature of the exhaust gas at the same time, and eliminate the flame sparks in the exhaust gas. A good exhaust system can also improve the efficiency of intake and exhaust. Efficiency, increase engine power, reduce fuel consumption.

[0003] Motor vehicle exhaust emissions have become one of the important factors affecting the environment, so various manufacturers have taken various measures to reduce motor vehicle exhaust emissions, such as installing catalytic converters in exhaust pipes can effectively reduce motor vehicle exhaust emissions. At present, there are mainly the following ways to connect the catalyt...
