Abstract
The utility model relates to an idling purifying device for a gasoline vehicle, which is characterized in that the utility model is mainly composed of a connection body (1), an electromagnetic needle valve (4), and a regulating valve (2), wherein, the electromagnetic needle valve (4) and the regulating valve (2) are arranged on the connecting body (1); a liquefied gas inlet, a regulating valve hole, and an installation hole of the electromagnetic needle valve are arranged on the connecting body (1); the installation hole of the electromagnetic needle valve is vertical with the regulating valve hole and the liquefied gas inlet; a hollow cavity (6) is also arranged on the connecting body; both ends of the hollow cavity are respectively communicated with a gas inlet straight pipe and a carburetor. The idling purifying device of the utility model supplies liquefied petroleum gas when the gasoline vehicle stays under an idling working condition. Because the liquefied petroleum gas can be sufficiently burned, and therefore, the discharge value of idling pollutants is obviously lower than the limited value specified by the national standard.
Description
The utility model relates to the automobile purification device, specifically gasoline car idling purification plant.
When the carburetor type automobile moves under idling operation, because ratio one air fuel ratio of air and fuel oil (gasoline) is lower, the mixed gas overrich, the gasoline combustion is around insufficient, cause CO and HC excessive concentration in the idling pollutant, the idling pollutant of these high concentrations causes more and more serious pollution to environment.For this reason, more and more severeer Abgasgesetz has been formulated in countries in the world.In order to reduce the discharge value of idling pollutant, carrying out unremitting effort both at home and abroad always, the measure of having taked comprises Electronic Fuel Injection (EFI), dual-fuel automobile, gas-fueled vehicles, electric vehicle and installs arrangement for catalytic purification etc. additional.But, perhaps because cost height (as Electronic Fuel Injection (EFI), electric vehicle etc.), perhaps because power and air feed influenced (as dual-fuel automobile, gas-fueled vehicles etc.), perhaps because effect lasting (as arrangement for catalytic purification etc.), applying of many measures is restricted.
The purpose of this utility model provides a kind of gasoline car idling purification plant, it is in the idle fuel way that can cut off the gasoline car Carburetor when moving under the idling operation automatically at gasoline car, connect the air supply channel of liquefied petroleum device, make gasoline car use liquid gas and reduce the exhaust emission of gasoline car when idling.
The purpose of this utility model is achieved in that this gasoline car idling purification plant is mainly by connecting body, electromagnetic valve, modulating valve is formed, electromagnetic valve, modulating valve are installed on the connecting body, connecting body is provided with the liquid gas inlet hole, regulates valve opening and electromagnetic valve mounting hole, the electromagnetic valve hole is vertical with the liquid gas inlet hole with the adjusting valve opening, also has a cavity on the connecting body, and its two ends are communicated with air inlet straight tube and Carburetor respectively.
At the liquid gas air inlet position explosion-proof valve is installed.Electromagnetic valve is connected with electronic controller.
This device can make liquefied petroleum gas (LPG) or the gasoline of supplying with gasoline car automatically switch by electronic controller, when automobile moves under idling operation, it can provide liquefied petroleum gas (LPG) to act as a fuel, and when automobile moves under other operating mode, then makes to use gasoline for the fuel.
Idling purification plant of the present utility model can be in when moving under the idling operation at gasoline car supplies with liquefied petroleum gas (LPG), and owing to liquefied petroleum gas (LPG) can fully be burnt, so the discharge value of idling pollutant is starkly lower than the limit value of national Specification.Test confirms, using liquefied petroleum gas (LPG) can make the power of gasoline vehicle engine descend to some extent, but idling operation is the not operating mode of output power of gasoline vehicle engine, when motor by idling during to middle and high fast transition, the automatic switching function of this device makes engine for combusting gasoline, thereby keeps its performance constant.The utility model can use household liquified gas, need not arrive the gas station aerating, and is easy to use.
Below in conjunction with accompanying drawing the utility model is described in further detail, but is not limited to shown in the accompanying drawing.
Fig. 1 is the structural representation of idling purification plant of the present utility model.
Among the figure, 1-connecting body, 2-modulating valve, 3-explosion-proof valve, 4-electromagnetic valve, 5-electronic controller, 6-cavity.
Embodiment, as shown in Figure 2, the utility model is mainly by connecting body 1, electromagnetic valve 4, modulating valve 2 is formed.Electromagnetic valve 4, modulating valve 2 are installed on the connecting body 1, on connecting body, be provided with the liquid gas inlet hole, regulate valve opening and electromagnetic valve mounting hole, the electromagnetic valve hole is vertical with the liquid gas inlet hole with the adjusting valve opening, and a cavity 6 is arranged on the connecting body, and its two ends are communicated with air inlet straight tube and Carburetor respectively.At the liquid gas air inlet position explosion-proof valve 3 is installed.Modulating valve 2, explosion-proof valve 3, electromagnetic valve 4 and electronic controller are the commercially available prod.
Connecting body 1 is installed between gasoline car Carburetor and the engine suction manifold, again modulating valve 2, explosion-proof valve 3 and electromagnetic valve 4 are fit into respectively in the connecting body 1, the explosion-proof valve place of being equipped with at connecting body connects the liquefied petroleum gas pipe, liquified petroleum gas cylinder (pressure regulator valve, pressure gauge etc. are arranged on it), electronic controller 5 are installed on the appropriate location in the car, the guide line of electromagnetic valve 4 links to each other with electronic controller 5, electronic controller 5 links to each other with the idling sensor with the idling solenoid valve of Carburetor again, and connecting body is connected by middle moulding pipe with pressure regulator valve on the liquified petroleum gas cylinder.When gasoline car moves under middle and high fast operating mode, gasoline car uses gasoline, this moment, solenoid valve 4 was in closed condition, liquid gas can not enter in the cylinder, when gasoline car changes idling operation over to, idling sensor on the Carburetor makes electronic controller 5 work, electronic controller 5 makes the idling closed electromagnetic valve idle fuel way on the Carburetor, and electromagnetic valve 4 is moved, open air flue, liquid gas promptly enters in the connecting body 1 and air mixing by electromagnetic valve 4 and modulating valve 2, enters the engine air in-cylinder combustion again.The flow of modulating valve 2 can regulate liquid gas is to obtain the best combustion effect, and explosion-proof valve 3 can prevent the blowback that blow back causes.
The profile of connecting body 1 can design according to the Carburetor of different vehicles, and modulating valve also can be regulated according to the discharge capacity of different automobile types.
The utility model also can use other gaseous fuel or the clean-burning liquid fuel of energy.
