RU152531U1 - SILENCER RECEPTION PIPE WITH NEUTRALIZER - Google Patents

Abstract

A silencer receiving pipe with a converter, including a manifold flange, four input elements in the form of stepped pipes, deformation of the pipe in the form of dents symmetrically located relative to the central axis of the pipe is made on the extreme pipes, the middle pipes in the upper part at the outlet have an oval shape in the vertical section, different the fact that the exhaust pipe of the muffler with a converter, including a collector flange in the form of a rectangular plate with tides at the beginning and in the middle of the plate, and connected to it There are four curved nozzles made of Ø38 mm pipe, the leftmost and rightmost nozzles are the same in size, have the last bend mirrored in different directions, the middle left and right nozzles have the last bend in the opposite direction, so that the axis of each branch and the front edge contour the edges of the catalyst part form an angle of 90 °, on the casing of the catalyst part are fixed brackets with up or down edges.

Description

The utility model relates to exhaust devices equipped with cleaning agents and installed on 16 valve internal combustion engines of LADA vehicles.

Known exhaust pipe silencer with neutralizer assembly (patent RU No. 136988, registered in the State register of utility models 01/27/2014), including a collector flange, four input elements in the form of stepped pipes, the pipe deformation in the form of dents is made on the extreme pipes, symmetrically located relative to the central axis of the pipe, and in the upper part of each pipe there is compression, the middle pipes at the outlet are oval in vertical section.

The specified technical solution has the following disadvantage:

- this design can only be installed on 8-valve engines of LADA cars.

The technical task of the claimed utility model is to use the technical capabilities of the design specified in patent No. 136988 on 16 valve internal combustion engines of LADA cars.

The technical result of using the inventive utility model is to reduce the toxicity of engine exhaust gases by improving the “washability” of the control sensor, ensuring a uniformity of the exhaust gas flow rate of more than 0.9 and reducing labor costs in the manufacture of a receiving pipe with a converter.

The specified technical result is achieved due to the fact that the exhaust pipe of the muffler with the converter FIG. 1 and FIG. 2, consisting of the collector part 1 and the catalyst part 2, includes a collector flange 3 having the shape of a rectangular plate with tides at the beginning and in the middle for installing a heat-insulating screen (not shown in the application). The mounting dimensions of the plate 3 allow you to install the exhaust silencer intake pipe with the converter assembly on the exhaust manifold of the 16 valve engine of the LADA car. The plate is connected by four input elements in the form of stepped nozzles to the catalyst part 2, the extreme left 4 and right 7 nozzles are made with mirror-shaped bends, the axis of which and the contour of the cut-off 8 of the front edge of the catalyst part form an angle of 90 °. The nozzles do not have additional deformations. The middle left 5 and right 6 nozzles are made with mirror-opposite bends, the axis of which and the cut-off contour 8 of the leading edge of the catalyst part form an angle of 90 °, the oval shape of the end of the nozzles corresponds to the shape of the middle input channels of the catalyst housing of the catalyst part 2.

The drawings show: FIG. 1 is a general view in isometric view. Brackets with upward facing edges, FIG. 2 is a main view, FIG. 3 is a perspective view in general of brackets with ribs pointing downward, FIG. 4 is a main view, FIG. 5 is a side view.

Silencer exhaust pipe with catalytic converter, FIG. 1 contains a collector part 1 and a catalyst 2, made in accordance with patent RU No. 136988. The header part, FIG. 2 consists of a collector flange 3 in the form of a rectangular plate with tides in the beginning and in the middle of the plate for attaching a heat-insulating screen and four bent pipes made of a Ø38 mm pipe connected to it, the leftmost 4 and right 7 pipes are the same in size, having mirror-directed the last bend and the middle left 5 and right 6 nozzles having a mirrored multidirectional last bend. The last bend of all nozzles is made so that the axis of each nozzle and the contour of the cut-off 8 of the leading edge of the catalyst part form an angle of 90 °, which ensures a minimum clearance in the connection.

In FIG. 3, FIG. 4, FIG. 5 shows a utility model with brackets 8 mounted with ribs pointing down.
