Background
In some areas, a customer using a motorcycle does not directly start to a gas station to fill fuel when filling the motorcycle, but carries an oilcan to the gas station, and the fuel is filled in the oilcan to return home and then is repeatedly filled into the fuel tank of the motorcycle.
The above-described way of filling is very likely to result in the tank being overfilled (submerged to the highest point of the tank filler). And after filling, the motorcycle is generally kept stand and not started, and fuel oil is not consumed immediately. When the motorcycle is exposed to the sun at high temperature outdoors, the pressure in the fuel tank can rise to the pressure to press the fuel out of the fuel tank. After the fuel overflows due to the two conditions, the liquid fuel enters a carbon tank (about 200 mL) through an adsorption pipeline and then flows into a throttle body through a desorption pipeline, so that the fuel is over-concentrated and the starting of the motorcycle is failed. And after the fuel overflows and flows into the carbon tank, part of the fuel flows into the throttle body, and part of the fuel is discharged from the water leakage pipe of the carbon tank, so that the fuel is wasted.

Specifically, the oil can 4 is communicated between the pouring valve 3 and the carbon tank 6 through the second connecting pipe 5, and the horizontal position of the oil can 4 is higher than that of the oil tank 1. The above arrangement is that a temporary oil reservoir (oilcan 4) is provided between the pouring valve 3 and the canister 6, above the oil tank 1.
The invention provides a fuel recovery device, which at least comprises an oil pot 4, on one hand, after the oil pot 4 is arranged, when a user oversubstantially refuels an oil tank 1 or the oil tank 1 is stood and insolated, fuel overflowed due to high-temperature expansion can enter the oil pot 4 for temporary storage, and can prevent the fuel from directly flowing into a carbon tank 6 and a throttle valve body 8 after overflowing, thereby effectively solving the problem of flameout after starting caused by oversubstantial refuelling or long-term placement of high-temperature insolation. On the other hand, after the motorcycle starts to burn a part of fuel, the liquid fuel in the oilcan 4 can flow back into the oil tank 1, so that the oil cost is effectively saved. In addition, the oil gas is adsorbed by the carbon tank 6, and the liquid oil is temporarily stored by the oil pot 4, so that the discharge into the atmosphere is avoided, and the energy conservation and the emission reduction are effectively realized.
In some embodiments of the application, see fig. 5, the bottom of the oilcan 4 is provided with a lower opening 41 and the upper part is provided with an upper opening 42.

The arrangement ensures that the connecting pipeline between the oil pot 4 and the oil tank 1 inclines to the oil tank 1 in the whole course, and is more beneficial to the backflow of liquid fuel to the oil tank 1. And the position of the pouring valve 3 is reasonably arranged, so that the connecting pipeline between the oil pot 4 and the oil tank 1 is shortened as much as possible, and the whole structure is more compact.
In some embodiments of the present application, referring to FIG. 2, the connecting line (i.e., the second pipe segment 52) between the upper opening 42 and the carbon canister 6 has a downward sloping tendency to facilitate the circulation of oil and gas.
In some embodiments of the application, a one-way valve may be provided in the connecting line (i.e., the second tube section 52) between the upper opening 42 and the canister 6 to prevent liquid fuel in the tank 4 from directly flowing into the canister 6 during vehicle tipping or other extreme conditions.
In some embodiments of the application, referring to fig. 5, the bottom of the oilcan 4 is an inclined surface, and the lower opening 41 is provided at the lowest point of the inclined surface. The above arrangement ensures that the liquid fuel in the tank 4 will better flow back into the tank 1 when the motorcycle starts to burn off a portion of the fuel.
In some embodiments of the application, see fig. 5, the bottom of the oilcan 4 is at an angle B of 3 ° -10 °, preferably 5 °, to the horizontal. The proper inclination angle is set to facilitate the liquid fuel to flow back to the oil inlet box 1 better.
In some embodiments of the present application, referring to fig. 5, an accumulation chamber 43 is formed to protrude upward at a predetermined position of the inner top of the oilcan 4, and an upper opening 42 is provided at the accumulation chamber 43. This arrangement facilitates the collection of oil and gas in the oil kettle 4 at the collection chamber 43 and then out the upper opening 42.
In some embodiments of the application, see fig. 5, the accumulation chamber 43 is located on the same side as the lowest point of the inclined surface of the oilcan 4.
Gathering cavity in some embodiments of the present application, referring to fig. 1, 5 and 6, the basic shape of the oilcan 4 is an isosceles trapezoid, the bottom of which is an inclined plane, the upper part of the isosceles trapezoid is provided with an upward protruding gathering cavity 43 at a position corresponding to the low point of the inclined plane, and the angle between the waist of the isosceles trapezoid and the bottom is 60 ° -80 °, preferably 77 °.
In summary, the invention provides a fuel recovery device, which at least comprises the following advantages compared with the prior art:
first, can temporarily deposit because of the excessive fuel or long-term after placing the high temperature and insolate the fuel that overflows, effectively solve the excessive fuel or long-term after placing the high temperature and insolate the start-up after-flameout problem that brings.
And the second and temporarily stored fuel can flow back to the fuel inlet box 1 after a part of fuel is burnt out when the motorcycle is started, so that the fuel consumption cost is effectively saved.
Thirdly, the oil gas is adsorbed by the carbon tank 6, and the liquid oil is temporarily stored by the oil pot 4, so that the liquid oil is prevented from being discharged into the atmosphere, and the energy conservation and the emission reduction are effectively realized.
