Abstract
The utility model aims to design an air exhaust manifold for cars. Three groups of manifold components are composed of three stainless steel pipes. One end of the manifold components is connected with a connecting flange, and the other end is gathered together, is connected with a catalytic converter and is connected with a confluence pipe. The confluence pipe is connected with a flange. The catalytic converter for a metal carrier is additionally arranged between the manifold component and the confluence pipe by the air exhaust manifold of the utility model, and is used for converting part of harmful gas in the air exhaust manifold into innocuous gas to be exhausted to atmosphere. Thus, the waste gas is purified, the exhaust gas emission is improved and the pollution on environments is reduced.
Description
Technical field
The utility model relates to a kind of vent systems that is used for motorcar engine, relates to the gas exhaust manifold that connects in a kind of motorcar engine between cylinder and the outlet pipe specifically.
Background technique
Gas exhaust manifold is connected between the cylinder and outlet pipe of motor car engine, is used for the guiding of waste gas.Shown in Fig. 1 a, 1b, be respectively the structural representation of two different visual angles of existing gas exhaust manifold, three groups of manifold part 2a, 2b, 2c that form by three Stainless Steel Tubes, its end separately is connected to an adpting flange 1, be connected to convergence tube 3 after the other end is gathered together, convergence tube 3 links to each other with a flange 4 again; Wherein, adpting flange 1 is cylinder head (not shown) the relief opening side that is connected to motorcar engine, and flange 4 then is connected with the outlet pipe (not shown) of motorcar engine.Enter each pipeline of manifold part after waste gas in the cylinder comes out from relief opening so respectively, enter outlet pipe more together after converging to convergence tube then.This existing gas exhaust manifold, its adpting flange adopts corrosion resistant plate, each arm adopts Stainless Steel Tube, by being welded into assembly, have compared with more traditional cast iron gas exhaust manifold that wall is thin, material is even, on technology, avoided casting defect, advantage such as in light weight, but its effect is relatively simple, only plays waste gas and lead.
The model utility content
The purpose of this utility model provides a kind of gas exhaust manifold that is used for motorcar engine that the waste gas transformation efficiency can be significantly improved.
For reaching above-mentioned purpose, the gas exhaust manifold that is used for motorcar engine of the present utility model, be provided with three groups of manifold parts that form by three Stainless Steel Tubes, its end separately is connected to an adpting flange, after being gathered together, the other end is connected to convergence tube, convergence tube links to each other with a flange again, is characterized in: also have additional a catalytic converter between the connection mouth of described manifold part and described convergence tube.
This shows, gas exhaust manifold of the present utility model has increased the catalytic converter of a metallic carrier between manifold part and convergence tube, part harmful gas in the gas exhaust manifold can be converted into innocuous gas is discharged in the atmosphere again, thereby purified waste gas, improved toxic emission, thereby reduced pollution greatly environment.
For further specifying above-mentioned purpose of the present utility model, structural feature and effect, the utility model is described in detail below with reference to accompanying drawing.
Description of drawings
Fig. 1 a, 1b are the structural representations of two different visual angles of existing gas exhaust manifold.
Fig. 2 is the structural representation according to the gas exhaust manifold of a preferred embodiment of the present utility model.
Embodiment
Be illustrated in figure 2 as the structural representation that the utility model is used for the gas exhaust manifold of car, three groups of manifold part 2a, 2b, 2c that constitute by three Stainless Steel Tubes, its end separately is connected to an adpting flange 1, after being gathered together, the other end is connected to a catalytic converter 6, welding one lambda sensor seat 5 before catalytic converter 6 inlets, last catalytic converter 6 is connected to convergence tube 3, and convergence tube 3 is connected with a flange 4 again; Wherein, adpting flange 1 is cylinder head (not shown) the relief opening side that is connected to motorcar engine, and flange 4 then is connected with the outlet pipe (not shown) of motorcar engine.This shows, gas exhaust manifold of the present utility model has been set up the catalytic converter 6 of a metallic carrier between manifold part 2a, 2b, 2c and convergence tube 3, welded a lambda sensor seat 5 between catalytic converter 6 and each manifold part 2a, 2b, 2c, being used within it, portion fixedly installs a lambda sensor (not shown).Because the exhaust gas constituents in manifold part inside mainly is carbon monoxide, hydrocarbon, nitrogen oxide etc., in case be discharged in the atmosphere with the severe contamination air, therefore gas exhaust manifold of the present utility model has been set up this catalytic converter 6 especially, make part waste gas be converted into innoxious substances such as carbon dioxide and water by redox reaction, the part harmful gas that to will discharge in manifold part is converted into harmless gas and discharges, thereby has purified waste gas, has improved toxic emission.And lambda sensor is set in lambda sensor seat 5 mainly is the concentration that is used to detect each waste gas in the gas exhaust manifold, regulates the oxygen of suction port input and the proportioning of fuel oil thereby can produce a feedback information, and waste gas is burnt more fully.Because the structure of parts such as catalytic converter 6 and lambda sensor is a prior art, is that affiliated technician is known, just seldom give unnecessary details at this.
Be noted that in addition, why adopt the catalyst converter of metallic carrier and do not adopt the catalyst converter of ceramic monolith, be because the former have the latter can't be equal to and advantage: first, structurally, the catalytic converter of metallic carrier does not need encapsulation, can directly be welded on the gas exhaust manifold, and ceramic monolith need add the cushions, encapsulation is welded on the gas exhaust manifold relative complex on the technology more then; The second, because under the equal order said conditions, it is thinner that the wall thickness of metallic carrier can be done,, make the arrangement space of motor compact more so the catalyst converter of metallic carrier is littler than the volume of the catalyst converter of ceramic monolith; The 3rd, on function,, effectively raise the efficient that waste gas is converted into innoxious substance because the catalyst converter of metallic carrier has fast, the resistant to elevated temperatures advantage of ignition, reach higher emission request, especially the toxic emission requirement during engine start.
Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, under the situation that does not break away from the utility model spirit, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present utility model in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
