Abstract
The utility model relates to a single-fuel methanol engine fuel feeding device, which comprises an air inlet pipe and a methanol common-rail cavity, wherein one end of the methanol common-rail cavity is connected with the air inlet pipe, and the other end of the methanol common-rail cavity is connected with an engine air inlet channel. The single-fuel methanol engine fuel feeding device is characterized in that a methanol oil inlet channel and an oil return channel, a conical injection guide airway are arranged in the methanol common-rail cavity, the side surface of the methanol common-rail cavity is provided with a pressure regulating valve mounting seat, and the upper end of the conical injection guide airway is provided with a nozzle which is connected with the conical injection guide airway. The structure is made from alloy materials when designing, thereby reducing the production cost. Methanol is fully evaporated through using the conical injection guide airway and then is lead in the air inlet channel, thereby reducing the air inlet resistance, leading fuel to more smoothly enter an engine, and being more fully mixed with the air. Furthermore, the single-fuel methanol engine fuel feeding device further has the advantages of simple structure, strong generality and low making cost and the like.
Description
Technical field
The utility model belongs to engine aspirating system and combustion gas mixing systems technology field, particularly relates to a kind of single fuel methanol engine fuel supply device.
Background technique
At present, diesel engine air inlet system is only controlled the flow of air, and the gas handling system of petrol engine is arranged in oil sprayer on the suction tude, realizes fuel supply and air mixing.Single fuel methanol engine combustion mode is close with petrol engine, and fuel mixes outside cylinder with air, so when diesel engine being transform as single fuel methanol motor, need transform to adapt to the requirement of fuel gas handling system.If mode according to petrol engine, it is very big for the change of diesel engine intake pipe that nozzle is installed on suction tude, causes the significantly rising of cost, and change suction tude and determine to have different schemes for nozzle location, improvement effect determines that the time is longer, has prolonged the construction cycle of car load.The single-fuel methanol engine adopts multiple spot intake duct direct injection technology, need redesign engine inlets or air feeder structure.
Summary of the invention
The utility model provides a kind of simple in structure, conformability is strong, intake resistance is little single fuel methanol engine fuel supply device for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of single fuel methanol engine fuel supply device, comprise air intake duct, methyl alcohol rail chamber altogether, methyl alcohol rail chamber one end altogether connects air intake duct, the methyl alcohol the other end in rail chamber altogether connects engine inlets, it is characterized in that: described methyl alcohol is provided with methyl alcohol oil input channel, back oil road, conical jet guiding air flue in the rail chamber altogether, methyl alcohol side, rail chamber is altogether installed the pressure regulator valve fitting seat, in conical jet guiding air flue upper end the nozzle that is connected with conical jet guiding air flue is installed.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, the utility model has solved single fuel methanol engine fuel supply problem, and it is few to have proposed a change, and adaptability is strong, actual effectively scheme.For methanol fuel direct injection technology, this model utility adopts adds the methyl alcohol mode in rail chamber altogether outside engine inlets, reduced the transformation for cylinder cap intake duct and suction tude.Adopt alloy material to reduce cost when design, adopt conical jet guiding air flue that methyl alcohol is fully evaporated and introduce intake duct then, reduced intake resistance, it is more unobstructed to make fuel enter engine inlets, more abundant with air mixing; The utility model also has advantages such as simple in structure, general strong, low cost of manufacture in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view among Fig. 1.
Among the figure: 1, air intake duct; 2, methyl alcohol is total to the rail chamber; 2-1, methyl alcohol oil input channel; 2-2, back oil road; 2-3, conical jet guiding air flue; 3, engine inlets; 4, pressure regulator valve fitting seat; 5, nozzle.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1 to Fig. 2, a kind of single fuel methanol engine fuel supply device, comprise air intake duct 1, methyl alcohol rail chamber 2 altogether, methyl alcohol rail chamber 2 one ends altogether connects air intake duct 1, the methyl alcohol the other end in rail chamber 2 altogether connects engine inlets 3, wherein said methyl alcohol is provided with methyl alcohol oil input channel 2-1, back oil road 2-2, conical jet guiding air flue 2-3 in the rail chamber 2 altogether, methyl alcohol 2 sides, rail chamber is altogether installed pressure regulator valve fitting seat 4, in conical jet guiding air flue 2-3 upper end the nozzle 5 that is connected with conical jet guiding air flue 2-3 is installed.
Because the utility model adopts technique scheme, minimizing is to the change of former diesel engine structure, realize the versatility of part to greatest extent, between air intake duct and engine inlets, increase a methyl alcohol that supplies methyl alcohol to enter air flue and be total to the rail chamber, methanol fuel is total to the nozzle of installing in the rail chamber by methyl alcohol and sprays into the methyl alcohol conical jet guiding air flue of inside, rail chamber altogether, methyl alcohol enters in the engine inlets and air mixing by conical jet guiding air flue, and then enters the firing chamber.Adopt alloy material to reduce cost when design, adopt conical jet guiding air flue that methyl alcohol is fully evaporated and introduce intake duct then, reduced intake resistance, it is more unobstructed to make fuel enter engine inlets, more abundant with air mixing; The utility model also has advantages such as simple in structure, general strong, low cost of manufacture in addition.
