Abstract

The invention discloses a fuel atomizing nozzle of a sliding arc plasma-high disturbance cross structure. The fuel atomizing nozzle comprises an air inlet cavity a formed in an inner housing, whereina cyclone a is mounted at the bottom of the air inlet cavity a; an air inlet pipeline a communicating to the air inlet cavity a is formed in one side of the inner housing while an oil inlet pipeline is arranged on the other side of the inner housing, the oil inlet pipeline communicates to the top of the oil inlet cavity, the bottom of the oil inlet cavity are separately connected to an inclined downward channel a and an inclined downward arc-shaped channel b, the end parts of the channel a and the channel b form a cross spray hole, and a tungsten electrode penetrates an end cover, the air inlet cavity a and the cyclone a successively and extends into a sliding arc discharging area; an outer housing is connected to the periphery of the lower part of the inner housing, an air inlet pipelineb communicating to an air inlet cavity b is arranged on one side of the outer housing, and a cyclone b is arranged on the upper part of the air inlet cavity b. When an engine is ignited successfully,the nozzle can provide high activity plasma active groups continuously and stably to promote more full combustion, improve the combustion efficiency and reduce the pollutant discharge.

Description

technical field [0001] The invention relates to the technical field of fuel atomization nozzles, in particular to a fuel atomization nozzle with a sliding arc plasma-high disturbance cross structure. Background technique [0002] Nowadays, with the continuous innovation of engine technology, higher requirements are put forward for the characteristics of reliable ignition, high-efficiency combustion and low pollution emission of the combustion chamber. Studies have shown that the quality of fuel atomization will directly affect the fuel combustion process and the formation of pollutants. Therefore, improving the atomization quality and strengthening the control of the atomization flow field have become the focus of people's attention. At present, people generally optimize the nozzle structure, and optimize the fuel spray process by means of electrostatic spraying and externally enhanced electric fields and magnetic fields. Because of the ability of plasma excitation technol...
