Description
Technical field
The utility model relates to a kind of fuel vehicle exhaust emissions purification plant.
Background technique
Because of the fuel vehicle exhaust emissions is mainly CO and HC, the purification technics that adopts adopts the secondary air introductory technique more now.The secondary air introductory technique is divided into electric controlled gas-compensation and the unidirectional aeration valve mode of the secondary air behind the motor before the motor.The electric controlled gas-compensation product is to install suction tude additional under carburettor base, and link to each other with bypass solenoid valve, the solenoid valve inlet end is connected with empty filter, generally get engine rotational speed signal from spark coil, feed back to ECU (Electrical Control Unit) ECU, ECU is by the program of setting, speed conditions according to motor, send the pulse electrical signal instruction to solenoid valve, by solenoid valve and opened/closed operating frequency, the benefit of control secondary air is gone into amount; When engine speed was not high, throttle opening was little, and the air inlet of motor has pressure reduction, and the air-breathing inlet manifold that adds to of meeting entered motor with mixed gas after solenoid valve was opened, and reached the purpose of regulating air fuel ratio.And under the high engine speeds operating mode, the very big or standard-sized sheet of throttle opening, air inlet this moment is pressed very little or is not had the electric controlled gas-compensation DeGrain.Simultaneously, improper because of electric controlled gas-compensation is a ram charging if coupling is adjusted, engine power also can take place to descend, the motorcycle unstable idle speed, bad phenomenon such as starting difficulty, and cost is very high.
Unidirectional aeration valve mode is the pulse pressure reduction by engine exhaust, and when negative pressure, aeration valve sucks air delivery of supplemental oxygen content in the outlet pipe from the external world.The factor that influences aeration valve tonifying Qi effect has:
1, engine operating condition: because aeration valve adopts the reed-type one-way valve structures, from the experimental measurement result, be subjected to the restriction of reed response frequency, aeration valve has certain tonifying Qi effect when low engine speed, and air compensation is very little when high speed.
2, the mounting point of aeration valve: the general sky of aeration valve is contained on the outlet pipe or the engine exhaust cylinder head.If go into to make a slip of the tongue closely apart from silencing apparatus in the position that is installed in outlet pipe, when engine exhaust enters silencing apparatus, can produce reflected gas stream, the malleation that causes exhaust pulses pressure reduction is excessive and negative pressure is too small, influences the air inlet effect of aeration valve.
3, inlet pipe connection is very little to the greatest extent: the diameter of connecting tube is too small and length is long, can influence air inflow, is unfavorable for the tonifying Qi of aeration valve.
Because the tonifying Qi poor effect of secondary air product when the high engine speeds operating mode is more abominable for former machine discharging, particularly the dense motor of high-speed working condition mixed gas also must be put in order the auxiliary tone of Carburetor district.
The model utility content
The purpose of this utility model is in order to solve the deficiency of above-mentioned present technology, and provides a kind of cost low, and excellent catalytic effect does not need a kind of fuel vehicle exhaust emissions purification plant that motor and Carburetor are carried out any adjustment.
The purpose of this utility model is achieved by the following technical solution: a kind of fuel vehicle exhaust emissions purification plant, comprise outlet pipe, it is characterized in that comprising purification plant, described purification plant comprises ozonizer, air pump, power supply, described power supply provides power supply to air pump and ozonizer, the air outlet hole of air pump links to each other with the inlet hole of ozonizer, and the air outlet hole of ozonizer is connected with the vent systems of vehicle, and the air pump inlet hole communicates with ambient atmosphere.
Described power supply can be divided into accumulate pond or vehicle self power supply.
Adopt this model utility that the tail gas of motorcycle is purified, its effect is than also low in European secondary discharge standard.In order to reach better effect, when using the utility model, can guide plate be set in Vehicular silencer, ozone and exhausting air are fully mixed to reach better effect.It is low, easy for installation that the utility model compared with prior art has a cost, and do not influence any coupling of motor, advantage such as effective.
Description of drawings
Fig. 1 is the utility model structural drawing.
1, ozonizer; 2, the suction tude of ozonizer; 3, the steam outlet pipe of ozonizer; 4, air pump steam outlet pipe; 5, air pump suction tude; 6, air pump; 7, air pump motor; 8, lead; 9, ozonizer controller; 10, loam cake; 11, lower cover; 12, power line.
Concrete case study on implementation
The utility model is described in further detail below in conjunction with accompanying drawing.Fig. 1 has provided an embodiment of the present utility model, ozonizer 1 in Fig. 1, air pump 6, air pump motor 7, the steam outlet pipe 3 that is arranged at ozonizer on the lower cover 11 stretches out outside the lid, and the suction tude 2 of ozonizer links to each other with the steam outlet pipe 4 of air pump, air pump suction tude 5 links to each other with the external world, the controller 9 of ozonizer is arranged at loam cake 10, and is connected with ozonizer 1 by lead 8, the controller 9 of ozonizer, air pump motor 7, is linked to each other with power supply 13 by lead 12.
The inventor is applied to this model utility to measure its result such as following table on the motorcycle and to its discharging tail gas:
