Abstract
The utility model relates to an electric spray and atomization device for an engine. A vortex vacuum generator is sleeved at the lower part of an electric spray nozzle, fuel oil sprayed by the electric spray nozzle is sprayed downward through a central through hole of the vortex vacuum generator, a gas spray nozzle is also sleeved at the outer side of the vortex vacuum generator, a jet hole is arranged at the bottom of the gas spray nozzle and vertically corresponds to the central through hole of the vortex vacuum generator, a gas chamber which is composed of distances and performs the atomization function is arranged between the gas spray nozzle and the vortex vacuum generator, a gas inlet hole is arranged on the lateral surface of the gas spray nozzle, and the gas enters downward into the air chamber through gaps between the gas inlet hole, the gas spray nozzle and the vortex vacuum generator. Compared with the prior art, the electric spray and atomization device has the advantages that the utilization rate of the fuel oil can be enhanced, the oil consumption is decreased by 10 percent to 15 percent, and simultaneously the harmful gas emission is reduced.
Description
Technical field
The utility model is a kind of engine electric spray atomising device, relates to final controlling element and interface that engine electric spray atomization gas motor is engine electric spray and burning, belongs to the technical field of structures of product.
Background technique
The EFI atomising device of motor mainly contains three kinds of forms both at home and abroad:
1. the oil of single hole and porous type ejection forms taper oil column shape, and oil atomizing is bad;
2. high pressure simple oil vortex-spraying type;
3. gas cover type gas-liquid mixed formula.
The shortcoming that said structure exists is: first kind atomizing is bad; Second kind of high pressure oil vortex-spraying type easily forms the air inlet obstacle, reduced intake efficiency, influenced the volumetric efficiency of cylinder; The third high pressure oil does not become the atomizing ratio with low pressure gas mixed oil and gas pressure.
Summary of the invention
The utility model designs at above-mentioned problems of the prior art just a kind of engine electric spray atomising device is provided, and its objective is to make fuel oil more fully atomize, fully burn, and reaches and saves the effect that fuel oil reduces discharging.
The purpose of this utility model realizes by following measure:
This kind engine electric spray atomising device, it is characterized in that: at swirl vacuum generator of the bottom of EFI mouth suit, the fuel oil of EFI mouth ejection sprays downwards by the center through hole of swirl vacuum generator, gas nozzle of suit again in the outside of swirl vacuum generator, it is vertically corresponding with the center through hole of swirl vacuum generator that the bottom of gas nozzle processes a spray-hole, and it has one section to haze and turn the air chamber that spacing constituted of usefulness between the two, there is an inlet hole side of gas nozzle, and gas enters air chamber downwards by the slit between inlet hole and gas nozzle and the swirl vacuum generator.
The characteristics of this technological scheme are to add the gas nozzle that can introduce air, this air draught is entering the back along the formation of the slit between gas nozzle and swirl vacuum generator swirling eddy, this swirling eddy can mix and atomize more fully with fuel oil in air chamber, high velocity air when utilizing motor air-breathing forms vacuum in petrol jet oil spout zone, under the effect of vacuum, fuel oil is realized expanding, and improves oil gas atomizing and melting effect.And under the prerequisite of good atomizing, a certain amount of vegetable oil can also be added, like this in fuel oil.

Embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1, this kind engine electric spray atomising device, at swirl vacuum generator 4 of the bottom of EFI mouth 1 suit, the fuel oil of EFI mouth 1 ejection sprays downwards by the center through hole 5 of swirl vacuum generator 4, gas nozzle 2 of suit again in the outside of swirl vacuum generator 4, it is vertically corresponding with the center through hole 5 of swirl vacuum generator 4 that the bottom of gas nozzle 2 processes a spray-hole 7, and it has one section to haze and turn the air chamber that spacing constituted 8 of usefulness between the two, there is an inlet hole 3 side of gas nozzle 2, and gas enters air chamber 8 downwards by the slit 6 between inlet hole 3 and gas nozzle 2 and the swirl vacuum generator 4.
This device has been owing to there has been a good atomizing effect, therefore can add 5% renewable oils (rape oil) and burn in gasoline, and rape oil has the lubricity of High Temperature High Pressure, can improve the lubricity and the sealing of cylinder, can improve engine power.
On the Yi Mei automobile of Han River, reequip, carried out 20,000 kilometers demonstration tests (this test car has travelled 80,000 kilometers) after the repacking.Test result shows, uses this device can reduce oil consumption 10%～15%, and the harmful gas of discharging obviously reduces, and the automobile power engine strengthens.Its test result sees Table just like showing.
The utility model device compared with prior art can improve the utilization ratio of fuel oil, reduces oil consumption 10%～15%, has reduced discharge of harmful gases simultaneously.
