Abstract

A catalytic convertor is disclosed having a housing defining a catalyst chamber 13, an inlet 12 to the chamber 13, an outlet 14 from the chamber 13 and at least one catalyst coated matrix 15 a, b located within the chamber 13. High pressure gas jets 25 a, b located at the inlet 12 to the chamber 13 are provided to concentrate the flow of exhaust gases entering the chamber 13 onto a small part of the catalyst coated matrix 15a or one of the catalyst coated matrices 15a, b. <IMAGE>

Description

A CATALYTIC CONVERTOR This invention relates to a catalytic convertor for the exhaust system of an internal combustion engine.
Cata ] ytic convertors have been used for sometime particularly in the United States of America to reduce the release of obnoxious by-products of combustion Into the atmosphere.
Fly 1 of the accompanying drawings is a diagranmatic cross-sectio tnrough a standard type of catalytic convertor as currently in use.
Tne convertor comprises a housing 1, defining an entry section 2 for exhaust gases, a catalyst section 3 and an exit section 4.
Tne catalyst section comprises two matrices 5a,5# each of which deflnes a plurality of longitudinally extending passages 6 coated with a catalyst material such as platinum and which are open at end surtaxes 7, 8 to define inlets 7a and outlets 8a.
The housing is provided with a flange 10 at its inlet end for attachment to an exhaust pipe (not shown) and the housing is then widened at 11 to form the entry section 2.
A similar arrangement is provided at the opposite end ot the housing to enable the housing to-attached by means of a flange 12 to a tail pipe of the exhaust system.
It is a problem with such prior art exhaust systems that upon starting the engine there is a considerabl# -lelay before the catalytic convertor is working etticiently due to the large area of catalyst to be heated to the temperature at which conversion by catalytic action occurs.
It is an object of this invention to provide a catalytic convertor that overcomes the problems of the prior art.
According to the invention there is provided a catalytic convertor having a housing defining a catalyst chamber, an inlet to the chamber, an outlet from the chamber and at least one catalyst coated matrix located within the chamber wherein means are provided to concentrate the Slow of exhaust gases entering the chamber onto a small part of the catalyst coated matrix or one of the catalyst coated matrices.
Preferably, the flow is concentrated by high pressure gas jets located at the inlet to the chamber.
The high pressure gas jets maybe compressed air Dets.
The high pressure gas jets maybe at right angles to the flow of exhaust gases entering the chamber.
The high pressure gas dents maybe arranged to concentrate the flow of exhaust gases towards one side of the chamber.
Fig 2 of the accompanying drawings is a diagrammatic cross-section through a catalytic convertor according to the invention.
The convertor comprises a housing 11, defining an inlet section 12 for exhaust gases, a catalyst chamber 13 and an outlet section 14.
The chamber houses two matrices 15a,15b each of which detines a plurality of longitudinally extending passages 16 coated with a catalyst material such as platinum and which are open at end surfaces 17, 18 to refine inlets 17a and outlets 18a.
The noising is provided with a flange 20 at its inlet end for attachment to an exhaust pipe (not shown) Rnd tne housing is then widened at 21 to torm the inlet section 12.
4 similar arrangement is provided at the opposite end ot the housing to enable the housing to attached by means of a flange 22 to a tail pipe of the exhaust system.
A number of high pressure gas jets in the form of high pressure air jets 25 a,b are provided at the entry to the inlet section 12.
The air jets 25 a,b are connected via switching means 26 to a source of air at high pressure in the form of the compressor 27 and the reservoir 28. The compressor is driven by an auxiliary drive belt of the engine to which the catalytic convertor is connected.
Upon engine start up a blast of air is supplied to the air jet 25a causing tne exhaust gas flow to be diverted as shown. The flow of exhaust gas is thereby concentrated on a small area of the entry face 17a of matrix 15a. The flow of exhaust gas remains attached to that side wall of the inlet portion 32 until such time as flow can be returned to normal.
A short blast of air from jet 25b is then admitted causing the tiow to be detached trom the side wall of the inlet portion 12 and return to normal central flow.
During the period when the flow of exhaust gas is being concentated substantially all of the thermal energy present in the exhaust gas is available to heat the small area of matrix 15a upon which it is being directed. This results in rapid heating of this part of the matrix 15a which renders the catalyst in that drea active in a much shorter time than if the exhaust gas is allowed to impinge upon the entire open ena surface 17 of the matrix 15a.
