Abstract

PURPOSE: A method for improving a fuel injection method for vehicles by applying electrospray technology is provided to completely burn fuel as fuel particles with polarity are injected after being converted into ultrafine particles by repulsion. CONSTITUTION: An fuel injector for vehicles comprises an injector body(10), a part(17), a sharp charge injection electrode(15). The injector body comprises a fuel inlet and a fuel injection hole. The part generates high voltage inside the injector body. The charge injection electrode electrifies the fuel which is not injected yet when electric current is supplied.

분출이 될 때, 분자끼리 밀어내려는 성질에 의해 초 미립자화 되어 분사가        When ejected, the particles become super fine particles due to the nature of pushing out molecules

되어 연료(13)의 표면적을 크게 하여 완전 연소에 가깝게 연소가 될 수        To increase the surface area of the fuel 13 so that it can be burned close to complete combustion.

있으며, 연소 효율이 높아지게 되며 더 적은 연료로 더 큰 출력을 얻게 할        Will result in higher combustion efficiency and greater output with less fuel.

수 있도록 한 것이다.       I would have to.
