NEUTRALIZER OF VEHICLE 'CHEVROLE NIWA' (VAZ 2123)

摘要

The utility model refers to the exhaust devices that are equipped with cleaning means and installed on the internal combustion engines of the car. For the installation of a maximum volume catalytic unit on the Chevrolet Niva cars (VAZ 2123), which allows to ensure the best cleaning of the exhaust gases according to the E5 standard, to increase the service life of the neutralizer and at the same time to use the volume under the car's bottom rationally, the neutralizer housing is designed in such a way that the ratio Inner case dimensions, the width A / height B is 1.5, i.e. in the cross section is close to the oval, which makes it possible to install a catalytic block with a volume of 1.5221 liters. The input cone of the body, in the course of the exhaust gas flow, has a stepped section that goes into a rectilinear conical section, transition into a stepped section with radius conjugation of surfaces. The rectilinear section of the input cone in the cross section has an oval shape. The radial coupling values ​​of the first step segment r1 and r2, the radius conjugation values ​​of the second step segment r3 and r4, and the length of the straight section X are calculated and selected based on the design of the neutralizer of the Chevrolet Niva car (VAZ 2123). 6 Fig.
