Problems solved by technology

[0003] The disadvantage of these technologies is that for independent hydrogen, alcohol or gasoline and diesel injectors, it can neither effectively slow down or overcome the early ignition or deflagration caused by the high diffusion of hydrogen, nor is it helpful for liquid fuels, especially alcohol fuels. The fine mist spraying makes the combustion more complete; for the combustion method that uses a special mixer to mix and then sprays it through the injector, the engine fuel system is complicated and the control is complicated

Abstract

This invention relates to a gas-liquid mixed fuel sprayer containing an adjusting connecting cap, an outer body, a jet-injector, an isolation ring pad and a spread spring suitable for hydrogen-mellow mixed combustion internal combustion engines and turbine engines, which is advantaged that low energy combustion and extremely high diffusibility of hydrogen is helpful to complete combustion of liquid fuel, which is good in dispersed pulverization and burnt fully, early burning and deflagration of hydrogen is restrained to a certain stage, so the fuel system and its control method can be simplified greatly.

Description

Technical field [0001] The invention relates to a gas-liquid fuel mixed injector applied to power machinery, in particular to a fuel injection device applied to various internal combustion engines and gas turbine engines for mixed combustion of hydrogen and alcohol, hydrogen and gasoline and diesel. Background technique [0002] The hydrogen engine has the outstanding advantages of high energy conversion efficiency, good power performance and very little pollution. Hydrogen energy will become one of the ideal clean energy sources, and has attracted great attention and widespread use worldwide. In order to solve the problem of hydrogen storage and distribution, or because of the transition from gasoline and diesel to pure hydrogen fuel, or from the consideration of improving the thermal efficiency of the engine, hydrogen-alcohol, hydrogen-gasoline and diesel hybrid vehicles are increasingly becoming the research and development and promotion of countries all over the world. ...
