Abstract
The utility model discloses a fuel evaporation control device for a motorcycle, which comprises an gas-oil separator, a ventilation pipe, a toppling control valve and a carbon canister, wherein the gas-oil separator is fixed on the upside of the interior of an oil tank; one end of the ventilation pipe is inserted into the gas-oil separator and the other end extends out of the oil tank and is connected with the carbon canister through the toppling control valve; the carbon canister is communicated with the atmosphere through a pipeline. The gas-oil separator comprises a casing with an inner cavity; the top surface and the bottom surface of the casing are respectively provided with a through hole; and the ventilation pipe inserted into the inner cavity of the casing is close to the top surface of the casing. By adding the corresponding control device in an oil supply system and reasonably connecting the pipeline, the utility model can not only ensure the smooth oil supply of the oil channel, but also control the evaporation amount of the fuel to the atmosphere. Meanwhile, the arranging of the toppling control valve can stop the access timely to prevent the escape of the fuel when the vehicle topples.
Description
Technical field
The utility model relates to the fuel control unit on a kind of motorcycle, specifically is a kind of motorcycle fuel evaporation control gear.
Background technique
The fuel oil supply system of existing motorcycle directly communicates with ambient atmosphere, as long as under fuel tank has oil condition, fuel oil always can be evaporated in the atmosphere gradually and go, and causes certain environmental pollution.Constantly perfect along with the enhancing of people's environmental consciousness and environmental legislation, motorcycle industry requires the steam output of oil supply system intermediate fuel oil is carried out strict control, therefore, must in the motorcycle oil supply system, increase the control corresponding device, with the steam output of control fuel oil.
The model utility content
Technical problem to be solved in the utility model provides a kind of control gear that is installed in the fuel supply system for motorcycle, and this device can guarantee that the fuel feeding of oil circuit is unobstructed, can control the steam output of fuel evaporation in the atmosphere again.
Fuel evaporation control gear described in the utility model, comprise deaerator, breathing pipe, topple over control valve and canister, described deaerator is fixed on the fuel tank internal top, breathing pipe one end inserts deaerator, the other end stretches out fuel tank and connects canister through toppling over control valve again, and canister then is communicated with atmosphere by pipeline.
Above-mentioned deaerator comprises the shell with inner chamber, and outer casing top surface and bottom surface are respectively equipped with through hole, and the inlet of the breathing pipe of insertion shell inner cavity is near outer casing top surface.
Under the normal use condition of vehicle, fuel tank keeps communicating with atmosphere by this device, and the pressure in the fuel tank is identical with atmospheric pressure, makes oil circuit unimpeded, and motor can proper functioning.
If the fuel oil in the fuel tank evaporates, the through hole that oil gas sees through deaerator enters in the deaerator, more successively by breathing pipe, topple over control valve (be open mode this moment) and, in canister, be absorbed at last to canister, prevent that oil gas is leaked in the air.
When vehicle is toppled over accidentally, topple over control valve and cut off path rapidly, prevent the leakage of fuel oil.
The utility model can guarantee that by being connected increasing control corresponding device and the reasonable of pipeline in the oil supply system fuel feeding of oil circuit is unobstructed, can control the steam output of fuel evaporation in the atmosphere again.Be provided with simultaneously and topple over control valve, when vehicle is toppled over, can in time block path, prevented leaking of fuel oil.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of deaerator.
Embodiment
As shown in Figure 1, the utility model mainly comprises deaerator 1, breathing pipe 2, topples over control valve 3 and canister 4, deaerator 1 is fixed on the top of the fuel tank inner bag 8 of fuel tank 5 inside, breathing pipe 2 is fixed in the fuel tank inner bag 8 by fixed plate 7, one end of breathing pipe 2 inserts in the deaerator 1, the other end stretches out fuel tank 5, connects canisters 4 through toppling over control valve 3 again, and 4 of canisters are communicated with atmosphere by pipeline.
As shown in Figure 2, deaerator 1 comprises the shell 6 with inner chamber, and shell 6 end faces and bottom surface are respectively equipped with a through hole 7 and through hole 8, and the inlet of the breathing pipe 2 of insertion shell 6 inner chambers is near shell 6 end faces.
The function of major control element:
Deaerator: fuel oil is separated with oil gas, keep the fuel tank inner chamber to communicate, when the vehicle driving road surface of jolting with atmosphere, or gasoline may be by entering the deaerator inner chamber by through hole 7 during climb and fall, because action of gravity, oil through hole 8 are again flowed out, and can not enter in the breathing pipe 2.
Topple over control valve: under the normal behaviour in service of vehicle, keep path, when vehicle is toppled over, block path.
Canister: absorbing and filtering oil gas.
