Abstract

The utility model discloses a double-choke blade type oil-combustion atomizer, composed of a support frame, an inner choke, an outer choke and a blade, wherein, the blade is fixedly connected between the axial directions of the inner choke and the outer choke and positioned on the side identical with an oil inflow port in the through hole of a bracket. The kinetics actions of the blade, the inner choke and the outer choke to the fuel airflow are used, the atomizing effect of the fuel airflow is sufficiently changed, fuel saving rate is increased by about 20 %, power is increased up to 10 %, and the structure is simple; the utility model is suitable to be uses on various engines of vehicles.

Description

Two trunnion blade type oil-combustion atomizers

The utility model relates to a kind of vehicular engine oil-combustion atomizer, particularly a kind of pair of trunnion blade type oil-combustion atomizer.

Many in the prior art about having reported for work of fuel economizer, oil-combustion atomizer, as magnetized fuel economizer, nine hole atomizers etc.The principle of magnetized fuel economizer is to increase a magnetic core in oil circuit, and the effect by magnetic field separates the fuel molecule chain link, make the fuel oil particle become more tiny from face, thereby it is better to reach fuel atomization effect, the purpose of sufficient combustion.But from actual use condition, effect is also not obvious, and oil-saving effect is not good, fails effectively to apply; Nine hole atomizers are to increase a metal framework that circle is divided into nine apertures that differ in size in the vaporizer bottom, to change oil stream normal flow direction, improve fuel atomization effect, but it is reported that its fuel saving ratio has only 3%, effect is also not obvious, so be difficult to equally popularize in an all-round way.

The purpose of this utility model be to provide a kind of simple in structure, fuel atomization effect significantly improves, oil inflame efficient height, fuel saving ratio height, pollute little two trunnion blade type oil-combustion atomizers.

Realize that technical solution of the present utility model is: a kind of pair of trunnion blade type oil-combustion atomizer, it is characterized in that it is made of support, outer throat pipe, inner throat pipe, fan blade, mid-stent is provided with cylindrical hole, this through-hole wall outer throat pipe that is connected, inner throat pipe is arranged at oily inflow entrance one end at place, through hole medial axis, inside and outside trunnion fixedly installs fan blade between radially, inside and outside trunnion inboard is provided with the curved surface to the medial axis projection, form inner throat pipe neck and outer throat pipe neck, two neck positions occupy oily inflow entrance direction one side.

Principle of the present utility model is: from the cavity of fuel oil air-flow in the middle of an end of the present utility model enters outer throat pipe and inner throat pipe that Carburetor is introduced, the fuel oil air-flow that enters outer throat pipe also must be earlier by having the fixed fan blade at certain inclination angle, because interior outer throat pipe inwall is equipped with neck, like this, the fuel oil air-flow is through out-of-date, pushed to the center by the effect of trunnion neck on the one hand, outwards expand subsequently, simultaneously, be subjected to the positive action of fan blade, the fuel oil air-flow forms the rotation around axis, under the effect of multiple interaction effect power, form the turbulence and the eddy current of fuel oil air-flow, form fierce bump between the molecule, thereby make fuel particles become more and more littler, reach the effect of abundant atomizing.

The utility model compared with prior art, its remarkable advantage is: structure is simple especially, and is easy to install; Fuel atomization effect is good, and fuel saving ratio reaches more than 20%, and power increases about 10%; Discharge amount of exhaust gas reduces by 50%; Because atomizing effect is good, thereby makes oil, gas ratio reach 1: 20.

Fig. 1 is a kind of structural representation of of the present utility model pair of trunnion blade type oil-combustion atomizer.

Fig. 2 is the plan view of structure shown in Figure 1.

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

In conjunction with Fig. 1, Fig. 2, of the present utility model pair of trunnion blade type oil-combustion atomizer is by support (1), outer throat pipe (2), inner throat pipe (3), fan blade (4) constitutes, support is provided with cylindrical hole (5), outer throat pipe is fixed on through-hole wall, the outer throat pipe neck (7) that the upper end has a curved surface to form, inner throat pipe (3) is arranged at center, through hole upper end, be provided with the inner throat pipe neck (6) that forms by curved surface in oily inflow entrance direction one side, interior, between the outer throat pipe, be fixed with fan blade (4), totally 4, the inclination angle is 40, the long 20mm of inner throat pipe, the long 50mm of outer throat pipe, through-hole diameter 60mm, inner throat pipe external diameter 20mm.
