Description
Technical field
The utility model relates to electric vehicle field, refers to a kind of extended-range electric vehicle switch pressure regulating type fuel oil supply system especially.
Background technique
At present, the distance increasing unit of extended-range electric vehicle generally adopts small-power petrol engine to come to electrical power generators, and fuel oil supply system generally has two schemes:
The first scheme is that the layout of distance increasing unit fuel oil supply system is similar to motorcycle, and fuel tank is arranged in upper position of engine, and gasoline enters Carburetor through filter cleaner under gravity, and atomization and air are mixed to form inflammable mixture in Carburetor.Fuel tank and distance increasing unit are integrated together, and volume is large, is unfavorable for flexible arrangement.Owing to having motor in electric vehicle forward engine room, the arrangement space of distance increasing unit is very limited, arranges that often to cause distance increasing unit, motor radiating bad by force, and dismounting difficulty, even needs to increase forward engine room height etc.
First scheme is that distance increasing unit fuel oil supply system is similar to the oil supply system of old-fashioned Carburetor car, fuel tank and motor arranged apart, fuel tank position is relatively flexible.Gasoline enters Carburetor through parts such as fuel tank, oil pump, fuel filter, oil pipes, and atomization and air are mixed to form inflammable mixture in Carburetor.Need to add oil loading pump, and the pump oil pressure of oil pump needs to match with Carburetor, if the meeting bigger than normal of pump oil pressure causes carburettor float to set high than predetermined bits, fuel economy is deteriorated; If pump oil pressure is less than normal, can cause for shortage of oil, the problem such as even flame-out.
Therefore be badly in need of a kind of fuel oil supply system, distance increasing unit can be made to arrange relatively flexible, without the need to strictly carrying out mating of oil pump and Carburetor, fuel feeding can be cut off by force when needs again, having with low cost, easy to operate feature.
Model utility content
In order to the distance increasing unit solving existing fuel oil supply system is arranged dumb, or strictly need carry out the problem of mating of oil pump and Carburetor, the utility model provides a kind of extended-range electric vehicle switch pressure regulating type fuel oil supply system, it is relatively flexible that this system can make distance increasing unit arrange, without the need to strictly carrying out mating of oil pump and Carburetor; Fuel feeding can be cut off by force when needs again, have with low cost, easy to operate feature.
A kind of extended-range electric vehicle switch pressure regulating type fuel oil supply system that the utility model provides, comprising: fuel tank, fuel filter, petrol pump, air-strainer, Carburetor, cylinder; Also comprise tap changer; Described fuel filter one end connects described fuel tank, and the other end connects described petrol pump; Described petrol pump is also connected with one end of described tap changer; The other end of described tap changer is connected with the first end of described Carburetor; Second end of described Carburetor is connected with described air-strainer, and the 3rd end is connected with described cylinder.
Wherein, described tap changer is common water tap.
Wherein, described tap changer is special pressure regulator valve.
Wherein, the pressure of described petrol pump is greater than the pressure that described Carburetor mates.
Wherein, the parts of annexation are had all to be interconnected by oil pipe between described fuel tank, fuel filter, petrol pump, air-strainer, Carburetor, cylinder, tap changer.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, fuel tank and motor arranged apart, and by increasing pressure regulator valve between petrol pump and Carburetor, distance increasing unit can be made like this to arrange relatively flexible, again can when designing oil supply system without the need to strictly mating with Carburetor oil pump, and fuel feeding can be cut off by force when needing, have with low cost, easy to operate feature.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As the structural representation that Fig. 1 is a kind of extended-range electric vehicle switch pressure regulating type fuel oil supply system of the present utility model, this system comprises: fuel tank 1, fuel filter 2, petrol pump 3, air-strainer 4, Carburetor 5, cylinder 6 and tap changer 7.Wherein, one end of fuel filter 2 connects fuel tank 1, and the other end connects petrol pump 3; Petrol pump 3 is also connected with one end of tap changer 7; The other end of tap changer 7 is connected with the first end of Carburetor 5; Second end of Carburetor 5 is connected with air-strainer 4, and the 3rd end is connected with cylinder 6.
In system shown in Figure 1, petrol pump 3, by fluid sucking-off from fuel tank 1, enters Carburetor 5 through fuel filter 2 and tap changer 7, and the air exported with air-strainer 4 is mixed to form inflammable mixture and supply engine.This fuel oil supply system is the improvement to first scheme in prior art, namely after petrol pump, installs a tap changer additional, can play the function of regulating system pressure and force disconnect fuel feeding.Due to the existence of switch, without the need to strictly mating with Carburetor petrol pump during design oil supply system, only need choose the relatively large petrol pump of pump oil pressure, then manually the circulation area of by-pass cock or other modes regulate the adjustment realized system pressure, until carburettor float arrives specified altitude, and till the sufficient fuel feeding of energy.During owing to tentatively choosing oil pump, its pump oil pressure is close with input pressure needed for Carburetor, so pressure regulation process can complete very soon.
Preferably, tap changer is common water tap, and cost is low, serviceability good.
Preferably, tap changer can also select special pressure regulator valve.
Preferably, the pump oil pressure of petrol pump is greater than the pressure that Carburetor mates.
Preferably, the parts of annexation are had all to be interconnected by oil pipe between fuel tank 1, fuel filter 2, petrol pump 3, air-strainer 4, Carburetor 5, cylinder 6, tap changer 7.
In such scheme, fuel tank and motor arranged apart, and by increasing pressure regulator valve between petrol pump and Carburetor, distance increasing unit can be made like this to arrange relatively flexible, again can when designing oil supply system without the need to strictly mating with Carburetor oil pump, and fuel feeding can be cut off by force when needing, have with low cost, easy to operate feature.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
