Abstract

The invention discloses a preparation method of a compressed nano hydrogen bubble / diesel oil mixed fuel. The preparation method comprises the following steps that: hydrogen with preset pressure is supplied to a mixer from a hydrogen cylinder through a pressure regulating electromagnetic valve; a predetermined volume of diesel oil is supplied from an oil tank to the mixer through an oil pump, a flow controller and an electromagnetic valve; a controller controls a thrust generator to push hydrogen and diesel oil in a piston compression cylinder to reach preset pressure intensity; and then the hydrogen / diesel oil solution in the compression cylinder is released to an oil / gas separator for separation to obtain the nano hydrogen bubble / diesel oil mixed fuel, and after the controller drives a piston, a push rod and the thrust generator to reset, the mixed fuel preparation cycle can be started again. When the nano hydrogen bubble / diesel oil mixed fuel is combusted, the diesel engine only needs one set of oil supply system, and hardware of the oil supply system does not need to be adjusted; and economic and emission performances of the diesel engine can be greatly improved, the preparationefficiency of the mixed fuel can be improved, and the method is more suitable for industrial production of the nano hydrogen bubble / diesel oil mixed fuel.

Description

technical field [0001] The invention belongs to the alternative fuel technology of internal combustion engines, and in particular relates to a circulating preparation method of nanometer hydrogen bubble / diesel fuel mixed fuel which can be used as diesel engine fuel. Background technique [0002] In recent years, with the vigorous development of my country's economy and the improvement of people's living standards, cars have changed from "luxury goods" to "necessities" and entered ordinary people's families, which has brought about a rapid increase in my country's car production and ownership. In 2018, although the production and sales of domestically produced automobiles experienced a "slide", there were still 27.809 million newly produced automobiles, of which new energy vehicles accounted for less than 5%, and liquid fuel (gasoline, diesel) vehicles are still the mainstay of my country's automobile industry. mainstream products. However, my country's increasingly large aut...
