Atomization oil nozzle capable of improving oil injection efficiency

Abstract

The invention discloses an atomization oil nozzle capable of improving the oil injection efficiency. The atomization oil nozzle comprises an oil nozzle part; a filter screen, a solenoid electric valveand a needle valve are arranged in the oil nozzle part; the filter screen is arranged on an oil outlet of the oil nozzle part; the solenoid electric valve is arranged below the oil outlet; and the needle valve is arranged below the solenoid electric valve. The atomization oil nozzle is characterized in that the atomization oil nozzle further comprises a dispersion cover arranged at the end face of the lower part of the oil nozzle part; an atomization fan is arranged on the dispersion cover; and after the needle valve sprays oil liquid, the oil liquid is dispersed through the atomization fan on the outer side of the oil nozzle part, and the dispersion range is controlled through the dispersion cover. With the adoption of the atomization fan, through the positive rotation and negative rotation of the atomization fan, the dispersion area is raised or the atomization efficiency is improved, and the dispersion efficiency of the atomization oil nozzle can be improved through the adopted dispersion cover. When oil injection is required, the solenoid electric valve is started to upwards suck the needle valve, a needle valve port is opened, and the oil liquid is sprayed out of the needle valve.

Description

technical field [0001] The invention relates to an atomized fuel injector, in particular to an atomized fuel injector which improves fuel injection efficiency. Background technique [0002] At present, the domestic diesel fuel injector market is monopolized by foreign companies, and the design and manufacturing technology of domestic fuel injectors needs to be improved urgently. Therefore, it is particularly important to design fuel injectors with superior atomization performance. The method that has been recognized by the industry to improve the atomization performance is to increase the fuel injection pressure (for example, the current common rail electronically controlled injection system can provide an injection pressure of about 250MPa), but too high fuel injection pressure increases the accuracy of the injector. The manufacturing requirements and precision of coupling parts increase the processing and manufacturing cost of precision coupling parts of fuel injectors. Th...

The method that has been recognized by the industry to improve the atomization performance is to increase the fuel injection pressure (for example, the current common rail electronically controlled injection system can provide an injection pressure of about 250MPa), but too high fuel injection pressure increases the accuracy of the injector. The manufacturing requirements and precision of coupling parts increase the processing and manufacturing cost of precision coupling parts of fuel injectors, so improving the design of fuel injectors and manufacturing fuel injectors that are more conducive to fuel atomization become an effective way to reduce costs
