Abstract

The utility model discloses an automobile exhaust treatment device comprising an automobile exhaust front pipe connecting with an engine, an air suction pipe, a mixed gas combustion chamber, a spark plug arranged in the combustion chamber, a muffler connecting with the combustion chamber and an exhaust rear pipe. When the engine is started, the produced exhaust containing carbon monoxide, hydrocarbon, oxynitride, lead dust and other harmful substances flows through the exhaust front pipe, as the exhaust front pipe is trumpet-shaped, the flow rate of the exhaust produced by the engine is accelerated while passing through the small end of the trumpet port, the negative pressure is generated around the small end of the trumpet port, the air is sucked in from the air suction pipe and mixed with the exhaust flowing through the exhaust front pipe to generate most of combustible gas mixture which flows through the combustion chamber, the spark plug is arranged in the combustion chamber and connected with a distributor, the spark plug ignites ceaselessly, so that the unburned exhaust burns again, the harmful gases produced by the exhaust are reduced, and the air pollution is improved. The automobile exhaust treatment device is applicable to various types of automobiles.

Description

The vehicle exhaust treater

One, technical field

The utility model belongs to a kind of motor vehicle fittings, relates in particular to a kind of motor-vehicle tail-gas treater.

Two, background technology

The tail gas of present most self-propelled vehiclees directly is not discharged in the air through handling, owing to contain objectionable impurities in the motor-vehicle tail-gas: materials such as carbonic oxide, hydro-carbon, Nitrogen oxides, lead dust cause aerial contamination.Particularly big or middle city, because being on the increase of vehicle, the pollution that vehicle exhaust produces is more and more serious, that gives people healthyly brings influence.

Three, summary of the invention

The purpose of this utility model is exactly to reduce the improved vehicle exhaust treater of environmental pollution for market provides a kind of pernicious gas of vehicle exhaust that makes.

Main technical schemes of the present utility model is: it comprises before the vehicle exhaust exhaust that links to each other with automotive engine manages after pipe, the vehicle exhaust exhaust.Pipe partly is made up of mixture combustion chamber, silencer and tail gas outlet etc. after the vehicle exhaust exhaust, on the tube wall of back, air suction pipe is installed, and at the indoor installation light-up plug of mixed firing, silencer is arranged at after hybrid combustor and the vehicle exhaust exhaust between the pipe, and pipe is horn shape before the vehicle exhaust exhaust.

The beneficial effects of the utility model are: not only simple in structure, easy to make, neither influence the various performances of automobile after the installation, but long-term use; do not increase use cost; the pernicious gas that vehicle exhaust is produced reduces, and the protection environment is contaminated, is applicable to various types of automobiles.

Below in conjunction with accompanying drawing the utility model is further described.

Four, description of drawings

Fig. 1 is the utility model structural representation.

Among the figure, 1 is air suction pipe, and 2 is pipe before the vehicle exhaust exhaust, and 3 is the mixture combustion chamber, and 4 is light-up plug, and 5 is silencer, and 6 for managing after the vehicle exhaust exhaust.

Five, specific embodiments

As shown in Figure 1, choose and manage 6 after metallic material is made preceding pipe 2 of tubaeform vehicle exhaust exhaust and vehicle exhaust exhaust, pipe 6 is divided into parts such as mixture combustion chamber 3, silencer 5 and tail gas outlet after the described vehicle exhaust exhaust, and in hybrid combustor 3, be provided with light-up plug 4, the loudspeaker osculum of pipe 2 is managed in 6 after placing vehicle exhaust emissions before the vehicle exhaust emissions, is provided with air suction pipe 1 on the back tube wall.When implementing the utility model, when the tail gas stream that is produced after the engine start manages 2 before exhaust, because under the horn-like contraction mouth effect of the preceding pipe of exhaust, flow velocity is accelerated, and produces negative pressure around the exit skirt small end, and air is sucked from being arranged in the air suction pipe 1 on the tube wall of back, mix with the tail gas of pipe 2 before the exhaust of flowing through, form most of carburetion mixture,, be installed in the spark ignitor burning in it through combustion chamber 3.Because light-up plug ceaselessly lights a fire, failing the tail gas of after-flame burns in hybrid combustor 3 once more, and the contained pernicious gas of tail gas is reduced greatly, and the tail gas pollution that is discharged in the Nature air is greatly improved, applicable to various types of automobiles.

Claims

1. vehicle exhaust treater, it manages (6) after comprising the preceding pipe of vehicle exhaust exhaust (2), vehicle exhaust exhaust, it is characterized in that: pipe (6) comprises mixture combustion chamber (3), silencer (5) and the outlet of last person's gas after the vehicle exhaust exhaust, air suction pipe (1) is installed on the back tube wall, and in hybrid combustor (3), light-up plug (4) is installed.

2. a kind of vehicle exhaust treater according to claim 1 is characterized in that: pipe (2) is a horn shape before the described vehicle exhaust exhaust.
