Task of the present utility model provides a kind of petrol engine fuel oil hot water vaporization economizer, gasoline is at first vaporized, enter the air mixing of Carburetor and feeding again, to improve the combustion condition of motor, make priming speed fast, oil-saving effect is good, and smoke emission concentration is low, befouling environment is light, thereby overcomes the existing existing above-mentioned deficiency of fuel-saving technique.

Task of the present utility model realizes with following scheme: it has an annular water tank, and the internal orifice dimension of water tank is identical substantially with the petrol engine outlet pipe, and two ends are extruded with the joint that can be connected with outlet pipe; Water tank upper is established filler pipe, and the bottom sets out water pipe, establishes annular oil vapour box in the water tank; There is the vaporization coiler oil vapour box below around the inwall coiling of water tank, and an end of this coiler feeds oil vapour box, and the other end passes water tank and draws, and can be connected with the fuel supply line of petrol engine, and establish the pneumatics valve; Establish oily steam pipe on the oil vapour box, this oil steam pipe passes water tank draw after, be divided into two branch roads, the one tunnel can lead to gasoline engine carburetor, the control end of the logical said pneumatics valve in another road.

Fig. 1 is that master of the present utility model looks sectional view;

Fig. 2 is a use scheme of installation of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated:

According to shown in Figure 1,5 is water tanks among the figure, ringwise, diameter of bore is identical substantially with the petrol engine outlet pipe, and two ends are extruded with the joint that is connected with the petrol engine outlet pipe, can the utility model fuel economizer main body be serially connected in the middle of the outlet pipe by it, or between outlet pipe and the baffler.The top of water tank 5 is provided with filler pipe 10, is used for adding hot-water flooding to water tank first, and the bottom is provided with outlet pipe 3, in case of necessity the water in the water tank is emitted.Be provided with annular oil vapour box 7 in the water tank 5, there is vaporization coiler 4 below of oil vapour box 7 around the coiling of water tank 5 inwalls, and an end of this coiler feeds in the oil vapour box 7, and the other end passes water tank 5 and draws, and can be connected with the petrol engine fuel supply line, and establish a pneumatics valve 11; Oil vapour box 7 is provided with oily steam pipe 9, after this oil steam pipe is drawn from water tank 5, is divided into two branch roads, one the tunnel can lead to the Carburetor of petrol engine, to the fuel oil of Carburetor steam supplyization, the control end of the logical above-mentioned pneumatics valve 11 in another road is controlled oil circuit automatically by the pneumatics valve.

During use, as shown in Figure 2, can be serially connected in the middle of the petrol engine outlet pipe 14, or be serially connected with between outlet pipe 14 and the baffler 13 with the utility model fuel economizer main body by the outstanding joint of water tank 5 two ends endoporus, petrol engine fuel supply line 16 is provided with a bypass, and establish threeway command valve 15, and the bypass of fuel supply line 16, top is connected with the Outlet of coiler 4, terminal is connected with the end that oily steam pipe 9 is drawn, and adds a safety check 17.

Be higher than 65 ℃ hot water by filler pipe 10 to water tank 5 addings, close the main road of fuel supply line 16 by threeway command valve 15, open bypass, to coiler 4 fuel feeding, enter the gasoline in the coiler 4, by hot water heating vaporization, enter oil vapour box 7, and by oily steam pipe 9, one tunnel logical gasoline engine carburetor, the work of gasoline feed machine, the control end of the logical pneumatics valve 11 in another road is controlled automatically to pneumatics valve 11.When extraction pressure is higher than setting value, two barometric pressure for example, pneumatics valve 11 can cut out, temporary transient fuel cut-off, when oil-air pressure was lower than setting value, pneumatics valve row was again opened, continuation keeps in the oil vapour box 7 enough extraction pressures being arranged, the work of gasoline feed machine to the vaporization of vaporization coiler 4 fuel feeding.During the petrol engine proper functioning, Tail Pipe Temperature generally can reach more than 200 ℃, can heat water tank, replenishes the heat energy for fuel gasification.

Petrol engine will be when the long period quits work, hot water in the water tank 5 can be emitted by outlet pipe 3, get time use ready, particularly in the winter time, and when other seasons, water in the water tank can not put yet, close the fuel feeding bypass by threeway command valve 15, open main road, press the former oil circuit fuel feeding of petrol engine and work, when treating that water in the water tank 5 is heated to more than 65 ℃ by outlet pipe, then can close the fuel supply line main road by threeway command valve 15, open bypass, earlier with fuel gasification, send into Carburetor again and make petrol engine work by this fuel economizer.

For increasing the heat exchange area between water tank 5 and petrol engine outlet pipe, make petrol engine in the course of the work, the high temperature that makes full use of outlet pipe replenishes the heat energy of fuel oil hot water vaporization, said water tank 5, below oil vapour box 7, its diameter of bore strengthens, the bottom of enlarged portion, and said endoporus is divided into some [es.
