Embodiment
With reference to figure 1 and Fig. 2, present embodiment is that injection engine fuel oil turnaround system is applied to a locomotive carrier.Injection engine fuel oil turnaround system includes a fuel tank 10, a fuel tank cap 11, an oil pump 12, a fuel supply line 13, a sparger 14, a return line 15, a pressure regulator valve 16, a nozzle body 20, reaches an oil gas recycling can 21.Fuel tank 10 inside are dug and are provided with a grease chamber 102, in order to storing fuel oil, and offer an opening 101 in the top, see through fuel tank cap 11 and seal opening 101.
Sparger 14 be ornaments above fuel tank 10, and offer a nozzle 141, a fuel supply line connection mouth 142, an and return line connection mouth 143 on it.Fuel supply line 13 is to pick out from oil pump 12, and extends to the fuel supply line connection mouth 142 of sparger 14 and be communicated with.
15 of return lines are that the return line connection mouth 143 from sparger 14 extends to the fuel tank 10, but also special group is provided with pressure regulator valve 16 in return line 15 approach, so the fluid in the return line 15 is just to enter fuel tank 10 at last through pressure regulator valve 16 earlier.Pressure regulator valve 16 is to be fixed on fuel tank cap 11 bottoms with oil pump 12, so also be to be located immediately at fuel tank 10 inside and connection with it.
Need ben in addition, the relative position relation of each port need meet following on the sparger 14, be that return line is 143 the highest, fuel supply line connection mouth 142 takes second place, nozzle 141 is minimum, the definition of position height is the notion with general gravity field, as shown in Figure 2.
In above-mentioned oil supply system, its running is: with the pressurization of the fuel oil in the fuel tank 10, then fuel oil can be sent to sparger 14 through fuel supply line 13 to oil pump 12 earlier.Fuel oil is to enter sparger 14 from fuel supply line connection mouth 142, and air is promoted by fuel oil in the pipeline at this moment, and because of air specific weight is light than fuel oil, the part fuel oil can directly fall to nozzle 141 places, and air then almost upwards flows and accumulates in return tube connection mouth 143 places.Therefore air and part fuel oil are to get back to fuel tank 10 at last from return line connection mouth 143 through return line 15, pressure regulator valve 16.
Above-mentioned oil pump 12 pressure are set in the general range, and are about more than 4 pounds, and 16 may command pressure of pressure regulator valve are at 2.5 pounds.So, fuel oil can arrive nozzle 141 apace, and can allow the flow line internal pressure be maintained by pressure regulator valve 16, and makes unnecessary air and gasoline see through return line 15 to pressure regulator valve 16 eliminatings, reaches the purpose that allows sparger 14 keep specific oil-gas ratin.Therefore, engine running is comparatively smooth, does not have residual and the flame-out or car situation of air, particularly under the state of vehicle starting just.
Also demonstrate the fuel oil turnaround system in the drawings and include a nozzle body 20, an and oil gas recycling can 21 in addition, wherein nozzle body 20 is provided with an oil filler 201 and pours into for outside oil sources.10 of nozzle body 20 and fuel tanks respectively with an oil filling pipe 22, and an oil gas recovery tube 23 link to each other, oil gas recycling can 21 is connected in nozzle body 20 through a connecting tube 24.And on nozzle body 20, the link position of oil gas recycling can 21 and nozzle body 20 is higher than the link position of oil filling pipe 22 and oil gas recovery tube 23 and nozzle body 20 simultaneously.See through the setting of above-mentioned device for recovering oil and gas, the fuel fume of overflowing from fuel tank 10 is stopped then by active carbon utilize again.
With reference to figure 3, be the second preferred embodiment schematic representation.The present embodiment system layout is roughly same as the previously described embodiments, and only its difference is in, return line except that leading to fuel tank 10, also branches to oil gas recovery tube 23.The concrete structure of return line is to comprise leading portion pipe 31, back segment pipe 34, and branched pipe 35, links two pipes in addition and to be groups establish three-way pipe 33 in leading portion pipe 31 tail ends.And pressure regulator valve 32 is to be configured on the flow path of leading portion pipe 31, just before the split point.
With reference to figure 4, be the 3rd preferred embodiment schematic representation.This embodiment is similar to second embodiment, but difference is that return line is to branch to oil filling pipe 22, and just branched pipe 45 is to be connected to oil filling pipe 22.
In above-mentioned second and third embodiment, such shunting design equally also can reach the purpose of getting rid of air in the fuel oil, but has more strengthened the function that oil gas reclaims.Among Fig. 3, the oil gas one in the branched pipe 35 enters oil gas recovery tube 23, and its intermediate fuel oil part is just by gravity fall, and the air part arrives oil gas recycling can 21 because of more upwards flowing through nozzle body 20, connecting tube 24.The example of Fig. 4 also is to reach identical purpose with same principle.
The foregoing description only is to give an example for convenience of description, and the interest field that the utility model is advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
