Problems solved by technology

The commonly used servo motor single pump has a relatively complex structure, relatively low fuel pressure, and the highest short-circuit fuel pressure does not exceed 8 bar (bar). At the same time, the control of this kind of fuel pump is relatively complicated, so there is an urgent need for a light weight, high pressure, structure. Simple and reliable fuel pump

Description

technical field [0001] The invention relates to a fuel boosting machine in an engine, in particular to a moving-coil high-frequency boosting pump. Background technique [0002] The fuel injection system of the engine has a great influence on the performance of the engine. The fuel pressure directly affects the fuel atomization characteristics of the engine. Especially when the aviation two-stroke engine burns medium oil, the atomization is relatively difficult and requires a higher pressure. At the same time, the fuel pump is required to have a relatively simple structure to ensure the power-to-weight ratio and reliability of the engine. The commonly used servo motor single pump has a relatively complex structure, relatively low fuel pressure, and the highest short-circuit fuel pressure does not exceed 8 bar (bar). At the same time, the control of this fuel pump is relatively complicated, so there is an urgent need for a light weight, high pressure, structure. Simple and re...
