Embodiment 1

[0025] Example 1 as Figure 1-4 As shown, a liquid fuel quantitative mixing device for a vehicle engine includes a pressure regulating valve A, a distributor B and a mixer C connected sequentially by bolts and sealing gaskets;

[0026] The middle part of the pressure regulating valve housing 5 of the pressure regulating valve A is a pressure regulating valve chamber, the first oil return pipe 6 of the pressure regulating valve and the second oil return pipe 28 of the pressure regulating valve are straight pipes with a bell mouth at one end, and the horn There is a gap between the ports and it is relatively placed in the middle of the pressure regulating valve chamber. The straight pipes protrude from the middle of the upper and lower ends of the pressure regulating valve chamber respectively, and are sealed with the pressure regulating valve chamber. The tanks of the two fuels are connected;

[0027] The pressure diaphragm 2 is placed in the gap between the first oil return p...

Abstract

The invention provides a fluid fuel quantitative mixing device for a vehicle engine. The fluid fuel quantitative mixing device comprises a pressure adjusting valve A, a distributor B and a mixer C, wherein the pressure adjusting valve A, the distributor B and the mixer C are sequentially connected through bolts and sealing gaskets. The fluid fuel quantitative mixing device is unique in design, simple in structure, high in reliability and easy to manufacture. The mixing precision of two kinds of liquid fuel is high, the two kinds of liquid fuel are quantified and fully mixed according to the requirement of practical working conditions of the engine, pressure fluctuation in an oil way is reduced, the fuel supply pressure is stable, the requirement for fuel combustion in the engine is met, fuel replacement is facilitated, and the fluid fuel quantitative mixing device is used on the mixed fuel engine to achieve the functions of energy conservation and emission reduction when the mixed fuel is used.

Description

technical field [0001] The invention belongs to the technical field of controlling the fuel injection quantity of a cylinder fuel injector of an automobile mixed fuel engine, and in particular relates to a quantitative mixing technology of two liquid fuels of an automobile mixed fuel engine. Background technique [0002] Energy shortage and environmental pollution have become urgent problems to be solved. Petroleum reserves are getting less and less, and the use of alternative fuels can effectively reduce the emission of vehicle exhaust pollutants. For the fuel of diesel engines, some scholars propose to use petrochemical diesel as the basis, adopt technological solutions such as blending and reforming of oxygenated fuel and petrochemical fuel, change the physical and chemical properties of fuel, redesign the fuel, expect to improve the atomization quality of fuel, and expand the uniformity. The proportion of mass premixed combustion can be optimized to optimize the combust...
