Problems solved by technology

[0005] 1) One-time fuel distribution, poor fuel supply uniformity, the distribution of the flow rate of each fuel injection hole mainly depends on the internal fuel flow channel, and the machining accuracy has a great influence on fuel uniformity;
[0006] 2) The fuel supply pipeline is long, and the response of the oil thrower system to the change of fuel flow is slow

Embodiment Construction

[0028] In order to make the objects, content, and advantages of the present invention, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] The present invention provides a fuel supply component having a short fuel distribution and a short fuel supply path. This oil supply structure can effectively improve the uniformity of fuel atomization while increasing the response capability of oil supply systems on fuel pressure changes.

[0030] Such as Figure 1 to 3 As shown, a secondary dispensing fountain structure provided by the present invention is composed of a supply assembly 1 and a fuel disc 2;

[0031] Wherein, the oil supply assembly 1 is a bicyclic chamber structure, and the two cycascular cavities are connected by three axial fuel channels; the oil-side ring cavity is directly connected to the fuel tube, and the end surface of the oil side ring cavity is performed. The an...

Abstract

The invention relates to a secondary distribution oil supply structure, and belongs to the technical field of engines. Compared with the prior art, the oil supply structure has the advantages that a secondary fuel oil distribution mode is adopted, the uniformity of an engine oil supply system is improved, and the uniformity degree of a combustion chamber outlet temperature field is improved.

Description

Technical field [0001] The present invention belongs to the field of engine technology, and more particularly to a secondary distribution oil supply structure. Background technique [0002] Oil plate is widely used in small and medium-sized engine combustion chambers for fuel atomization. Compared with the conventional nozzle, the oil disc has the advantages of low oil supply pressure, simple structure, light weight, good atomization resistance; relative to the evaporative tube, the oil disc has the advantages of simple starting. The oil pan is generally fixed to the engine rotor, and when the engine is working, rotate with the rotor, relies on the action of centrifugation, and atomization. The processing accuracy of the oil disc and the oil supply method, etc. directly affect the uniformity of the fuel flow distribution. The uneven fuel flow will cause local hotspots and abnormal noise when the engine is working, and the turbine blade brings catastrophic consequences. [0003] M...
