RU164973U1 - SILENCER RECEPTION PIPE WITH NEUTRALIZER - Google Patents

Abstract

A silencer receiving pipe with a converter, including a collector flange in the form of a rectangular plate connecting the output channels of the head of the block with four input elements, in the form of bent pipes articulated with the gas receiving part of the pipe of the receiving silencer receiver with a catalyst, having an oval shape, in the direction of the exhaust gases ( OG), along the axis of symmetry, at an angle to which the outlet pipe is located, also having an oval shape in a perpendicular section, with a flange fixed to it, connecting to the exhaust system gases (IWG) of automobile engines, characterized in that the manifold flange is in the form of a plate with cutouts repeating the contours of the head of an 8-valve engine block connected by four input elements, in the form of bent nozzles having dents on the side surface that are connected to the housing consisting of two upper and lower stamped half-shells welded in a horizontal plane made of heat-resistant corrosion-resistant steel, representing a single unit from a gas receiver with a mounted sleeve of the oxygen sensor, the catalyst part, consisting of a catalytic unit fixed by a heat-resistant gasket and an outlet gas receiver, rotated in space so that the outlet pipe connected to it, in the form of a pipe whose length is equal to the diameter, and a flange mounted on it, provide connection with the system SVOG of the 8-valve engine, as well as above the outlet pipe, a stamped plate of heat-resistant corrosion-resistant steel is installed, and a bracket with a nut is attached to the upper half-body.

Description

The utility model relates to exhaust devices equipped with cleaning agents and mounted on internal combustion engines of a vehicle.

Known exhaust pipe silencer with a neutralizer (patent application RU No.2010140933, priority 06.10.2010), which includes a rectangular collector flange connecting four input elements in the form of bent pipes articulated with the gas receiving part of the pipe body of the exhaust silencer with a neutralizer. At the exit from the body, which has an oval shape, along the path of exhaust gases (OG), along the axis of symmetry, an outlet pipe is arranged at an angle, also having an oval shape in a perpendicular section, with a flange fixed to it, for connection with a gas exhaust system (CBOG ) 16-valve engine of the car LADA "Priora" "Kalina", "Samara".

The disadvantage of this design is the following:

1. For the manufacture of the specified outlet pipe requires sophisticated special equipment, and, as a consequence, a complex process and cost of production.

2. The design of the manifold flange does not allow the exhaust silencer intake pipe with the converter to be installed on the Vesta 8-valve engine, the body and the outlet pipe do not allow the outlet flange to be connected to the SVOG of the 8-valve engine.

The technical task of the claimed utility model is to simplify the manufacturing technology of the exhaust silencer pipe with the converter.

The technical result of using the claimed utility model is the development of a technological design that makes it possible to use it in the SVOG of the Vesta car with 8 valve engines.

1 The specified technical result is achieved due to the fact that the exhaust pipe of the muffler with a converter, including a manifold flange in the form of a plate with cut-outs repeating the contours of the block head connecting the output channels of the block head of the 8-valve engine of the Vesta family car with four input elements in in the form of bent pipes having dents on the lateral surface, which are connected to a housing consisting of two upper and lower stamped half-bodies welded in the horizontal plane, made from heat-resistant corrosion-resistant steel, representing a single unit from the gas receiver with the installed sleeve of the upper oxygen sensor, the catalyst part in the composition of the catalytic unit, fixed with a special heat-resistant gasket and the outlet gas receiver, rotated in space so that the outlet pipe connected to it is equal in length to the diameter and a flange mounted on it, allow you to connect the exhaust silencer pipe to the VVOG of the Vesta automobile. To increase the strength of the connection of the outlet pipe to the body, a stamped plate of heat-resistant corrosion-resistant steel is installed. On the upper half-housing there is a bracket with a nut for installing a thermo and soundproof screen, which is part of the engine of the Vesta car.

The drawings show: FIG. 1 is a main view of a receiving pipe with a converter, FIG. 2 is a side view.

The exhaust pipe of the muffler with the neutralizer assembly contains a collector flange 1, in the form of a plate with cutouts repeating the contours of the head of the block of the 8-valve engine of a Vesta family car, four inlet elements 2, in the form of bent pipes with dents on the side surface, which connected to the casing, consisting of two horizontal welded upper 3 and lower 4 stamped half-shells made of heat-resistant corrosion-resistant steel, representing a single unit of the gas receiver 5, with installed sleeve 6, the upper oxygen sensor, the catalyst part 7, in the composition of the catalytic unit, fixed with a special heat-resistant gasket and outlet gas receiver 8, the outlet pipe 9, in the form of a pipe whose length is equal to the diameter, with the fixed sleeve 10 of the lower oxygen sensor and mounted on it flange 11. To increase the strength of the connection of the outlet pipe 9 to the housing, a stamped plate 12 made of heat-resistant corrosion-resistant steel is installed. On the upper half-housing placed bracket 13 with a nut.
