Abstract

The utility model relates to a field of combustion engine technology, and is arranged at the exhaust pipe of the engine and used for reducing to release the harmful gas of the engine. The utility model mainly consists of a cylinder(1), an air guiding body(2) and air guiding blades(3); wherein the air guiding body takes a bullet shape, one end takes s shape of cone, the other end takes a shape of conical bluntness, and the middle takes a shape of circular cylinder; the number of the air guiding blades(3) is three to four, taking a shape of rectangle, and each air guiding blade is bent to be a certain radian, and vertically fixed at the air guiding body in an interval of equal radian. The air guiding body and the air guiding blades are fixed at the internal wall of the cylinder by a joining-piece(5). The utility model is capable of making the exhaust gas released from the firebox of the engine forms an eddy current, and then released, forming a negative pressure in the firebox, making the fresh air speeding up to flow into the firebox, and making the fuel completely atomized; thereby the utility model has the advantages of complete burning and powerful operation, and at the same time, saving the fuel and reducing the release of the harmful gas.

Description

A kind of reduction motor noxious gas emission and fuel-saving device

Technical field

The utility model relates to the combustion engine technical field, particularly a kind of reduction motor noxious gas emission and fuel-saving device.

Background technique

Along with the sustainable and stable development of national economy, the output and the sales volume of the annual automobile of China are all increasing substantially, and use the crowd of automobile more and more.Existing motor car engine generally adopts traditional intake and exhaust mode, deficiency of air, and fuel atomization is insufficient, and it is insufficient therefore to burn, and the black smoke of discharge is a lot.Harmful gas such as a large amount of carbon monoxide, hydrocarbon, oxynitrides causes severe contamination to atmosphere in the black smoke, and the healthy of people in serious threat.In order to improve environment for human survival, reduce the pollution that the tail gas of vehicular emission causes atmosphere, people are seeking solution always.At present in order to reduce the Motor Vehicle discharge of harmful gases, make fuel sufficient combustion as far as possible, increase the air inlet amount, reduce the resistance of intake and exhaust, the intake and exhaust manifold of motor has been done some improvement: select for use ganoid stainless steel material to replace original cast iron, cast aluminium on the one hand, the shape with intake and exhaust manifold changes the arc streamline into by original right angle type on the other hand.Though more than improve certain effect is arranged, very not remarkable.The part Motor Vehicle is also arranged in order to reduce discharge of harmful gases, in gas exhaust manifold, install a three-way catalytic apparatus additional, reduced discharge of harmful gas in tail gas to a certain extent, but after increasing this device, strengthened the resistance of exhaust again.Because exhaust is obstructed, waste gas can not effectively be discharged in the firing chamber, and air inlet is obstructed, and causes deficiency of air, and fuel atomization is insufficient, incomplete combustion.

Summary of the invention

The purpose of this utility model is to provide a kind of engine exhaust that makes to quicken discharging, improves induction air flow ratio, thereby makes the air inflow abundance, and fuel combustion is abundant, reduces motor noxious gas emission and fuel-saving device.

The purpose of this utility model is achieved by the following technical solution: a kind of reduction motor noxious gas emission and fuel-saving device mainly are made of cylinder 1, deflector 2, guide vane 3.Cylinder 1 usefulness stainless steel is made, and its internal diameter is slightly larger than the outlet pipe external diameter, and an end has 2-4 to vertical masonry joint (4) along vertical dashing.Deflector 2 usefulness metals are made bullet shape, and an end becomes cone blunt nosed, and the other end becomes cone, and the centre is a cylindrical body.Lonely degree is shaped on 3～4 semicircle holes (6) at interval around the cylindrical body etc.Guide vane (3) has 3-4, all does rectangularity book sheet with metallic material.All blades all curve certain radian, are shaped on two perpendicular connecting sheets (5) on the long limit.Be shaped on a semicircle end ear (7) on another long limit.The radian difference that each blade is bent is calculated principle according to Archimedian screw and is drawn.Several guide vanes (3) vertically are fixed in the semicircle hole (6) on the cylindrical body of deflector (2) by end ear (7), and making lonely degree that guide vane become with the vertebra point of the cone of deflector in R210～250 scopes, another side is fixed on the inwall of cylinder (1) by connecting sheet (5).During use, this device is enclosed within on the outlet pipe, being fixed by clamp (8) and screw (9) gets final product.

The utlity model has following good effect:

After engine exhaust pipe is installed the utility model, during engine operation, under the effect of deflector and guide vane, the waste gas of discharging from engine chamber forms eddy current rapidly and quickens to discharge from the vertebra point of deflector and guide vane crack, form certain negative pressure in the firing chamber, makes fresh air quicken to flow to during air inlet, strengthen the air input, make that fuel fully atomizes, sufficient combustion, work done is powerful, and fuel saving also reduces noxious gas emission simultaneously.According to preliminary test, after motor is installed the utility model, increase power 10%～30%, fuel saving 3%～10% reduces tail gas noxious gas emission 10%～30%.

The utility model is installed in the engine aspirating system, also can play similar effect.

Fig. 1 is the utility model structural representation.

Fig. 2 is the guide vane schematic representation.

Among the figure, 1 cylinder, 2 deflectors, 3 guide vanes, 4 vertical masonry joints, 5 connecting sheets, 6 semicircle holes, 7 end ears, 8 clamps, 9 screws.

Embodiment

A kind of reduction motor noxious gas emission and fuel-saving device mainly are made of cylinder (1), deflector (2), guide vane (3).Add and make short cylinder (1) with stainless steel man-hour, make its internal diameter be slightly larger than the engine exhaust external diameter of pipe, and at one end along vertically towards 2-4 to vertical masonry joint (4).With metallic material deflector (2) is made bullet shape, an end is made cone shape, and it is blunt nosed that the other end is made cone, and cylindrical body is made in the centre.Around cylindrical body, wait radian to dash 3～4 semicircle holes (6) at interval.With metal book sheet guide vane is cut into rectangular, wherein folding has two perpendicular connecting sheets (5) on the long limit, semicircle end ear (7) of system on another long limit, do 3～4, each guide vane all curves certain radian, the radian difference that each blade is curved, its numerical value calculates principle by Archimedian screw and draws.Then several guide vanes (3) vertically are fixed in the semicircle hole (6) on the cylindrical body of deflector (2) by end ear (7), and make lonely degree that guide vane become with the vertebra point of the cone of deflector between R210～250.Again with deflector (2) together with guide vane (3), make cone vertebra point that cylinder one end of vertical masonry joint (4) be arranged dorsad, be fixed on by connecting sheet (5) on the inwall of no vertical masonry joint (4) one ends of cylinder (1) and get final product.During use, open the vertical masonry joint of several correspondences, this device is enclosed within the outlet pipe tail end, clamp (8) is inserted in the vertical masonry joint (4), it is fixed getting final product with outlet pipe with screw (9) at the outlet pipe tail end.
