The utility model comprises a cavity type tank body, a valve seat mounted on the upper part of the tank body and a tank internal oil pipe. An oil inlet channel and an oil outlet channel are arranged on the valve seat, the upper end of the tank internal oil pipe is fixed on the valve seat and communicates with the oil outlet channel, the lower end of the tank internal oil pipe is close to the bottom of the tank body and communicates with the internal cavity of the tank body, an input valve and a pressure-regulating valve and a pressure meter are fixed on the valve seat, the input valve communicates with the internal cavity of the tank body via the oil inlet channel, one end of the pressure-regulating valve communicates with the oil outlet channel, the other end communicates with the dimethyl ether fuel feeding pipe of the engine, and the pressure meter communicates with the internal cavity of the tank body via the oil inlet channel. The utility model has the advantages of simple structure and small volume.
Description
Technical field
The utility model belongs to the technical field of internal-combustion engine, is specifically related to a kind of dimethyl ether engine fuel pot that prevents to produce because of the liquid dimethyl ether vaporization in the dimethyl ether engine liquid fuel supply pipeline vapour lock.
Background technique
Diesel engine is the power of automobile, tractor, engineering machinery, train, naval vessel and battlebus, and the diesel engine consumption increases year by year, and refines the petroleum resources exhaustion day by day of diesel oil, and countries in the world are all in the alternative fuel of seeking diesel oil for this reason.Countries in the world generally acknowledge that through development test dimethyl ether is the clean fuel that substitutes diesel oil.But after diesel engine changed into dimethyl ether engine, because the boiling point (25 ℃) of dimethyl ether is low, vapor tension (normal temperature is 0.5MPa down) is high, the ducted liquid dimethyl ether of liquid fuel supply is easily vaporized the generation vapour lock, cause motor not run well, take both at home and abroad to prevent that the dimethyl ether in the fuel channel from producing vapour lock for the method for dimethyl ether fuel jar pressurization to the dimethyl ether pressurization or with the elevated pressure nitrogen gas tank with pump; The equal more complicated of fuel supply system structure, the volume of realizing these two kinds of methods are big, have increased the difficulty of installing and using on automobile.
Summary of the invention
Technical problem to be solved in the utility model is to add armored pump or high-pressure nitrogen bottle causes dimethyl ether fuel feeding system complex structure, bulky problem in fuel supply system when avoiding above-mentioned diesel engine dimethyl ether fuel fuel, provides a kind of and prevents that dimethyl ether in the fuel supply pipeline from producing the dimethyl ether engine fuel pot of vapour lock.
The technological scheme that the utility model technical solution problem is adopted is: the dimethyl ether engine fuel pot comprises the cavate tank body, the valve seat that install on tank body top, the jar inner oil tube that is provided with in the tank body, it is characterized in that having on the valve seat oil input channel and oil road, the upper end of jar inner oil tube is fixed on the valve seat and with oil road and is communicated with, the lower end of jar inner oil tube is near tank base, and communicate with tank inner chamber, fixing transfer valve on the valve seat, pressure regulator valve and pressure gauge, transfer valve communicates with tank inner chamber through oil input channel, pressure regulator valve one end is connected with oil road, the other end is communicated with the engine fuel supply pipeline, and pressure gauge is communicated with tank inner chamber through oil input channel.Charge into compressed nitrogen through transfer valve and oil input channel to tank inner chamber in advance, be pressed into liquid dimethyl ether through transfer valve and oil input channel to tank inner chamber again, close transfer valve, open pressure regulator valve, the liquid dimethyl ether in the tank inner chamber is subjected to the pressure effect of jar interior compressed nitrogen through jar inner oil tube, oil road, pressure regulator valve inflow engine dimethyl ether fuel feeding pipeline.
The beneficial effects of the utility model: solve the problem that dimethyl ether in the dimethyl ether engine fuel supply pipeline produces vapour lock, need in fuel supply system, not add armored pump or high-pressure nitrogen bottle again, simple in structure, volume is little.
