Description
Technical field
The utility model relates to a kind of petrol engine, particularly the fuel path system of petrol engine.
Background technique
Existing gasoline engine fuel oil-way system mainly comprises the fuel tank that has vent, by the Carburetor that transport pipe is communicated with fuel tank, the bottom of this Carburetor is provided with the mouth of draining the oil, it is realized sealing by oil discharge screw and drains the oil; Also be provided with the fuel oil throw over switch on the transport pipe.Generally; petrol engine is after operation is shut down; can retain in the Carburetor fuel oil is arranged; if do not start petrol engine for a long time; this fuel oil will volatilize; because fuel oil can produce colloidal material in the process of volatilization; this colloidal material is easily attached on the Carburetor internal components surface; thereby can cause petrol engine when start next time very the difficulty in addition can't start; after therefore if the petrol engine operation is shut down; need manually oil discharge screw to be turned on to emit the fuel oil in the Carburetor, the fuel oil that this is emitted is refunded to fuel tank again, therefore uses extremely inconvenient.
The model utility content
At above-mentioned deficiency, the utility model provides a kind of gasoline engine fuel oil-way system, and this oil-way system can realize that the fuel oil of retaining in the Carburetor is back to fuel tank automatically.
The purpose of this utility model is achieved through the following technical solutions: a kind of gasoline engine fuel oil-way system, the Carburetor that comprises the fuel tank that has closed fuel tank lid, is communicated with described fuel tank by transport pipe and be arranged at fuel oil throw over switch on the described transport pipe, wherein, the bottom of described Carburetor is provided with the mouth of draining the oil, and also is provided with return tube between described Carburetor and the described fuel tank; Described transport pipe is cross intercross arrangement with described return tube and is communicated with; Described fuel oil throw over switch is arranged at described transport pipe and is communicated with the place with described return tube.
The top of described fuel tank is provided with vent and breathing pipe; One termination of this breathing pipe is gone into vent and is communicated with the inner chamber of described fuel tank, the other end is communicated with the back with described fuel oil throw over switch and communicates with atmosphere, so that the air pressure in the described fuel tank inner chamber equates with barometric pressure, thereby the fuel oil in the described fuel tank can be flowed in the Carburetor smoothly, the transport pipe and the breathing pipe that are close to described fuel oil throw over switch place simultaneously are arranged in parallel, promptly adopt a fuel oil throw over switch can realize draining the oil and oil return between described fuel tank and the Carburetor, easy to use.
One end of described return tube is communicated with the mouth of draining the oil of described Carburetor, and the other end is communicated with the top of described fuel tank, and therefore the fuel oil in the described fuel tank inner chamber can not be back in the Carburetor.
The utility model is set up return tube between existing fuel tank and Carburetor, this return tube is cross intercross arrangement with transport pipe and is communicated with, and connection place at both is provided with the fuel oil throw over switch, promptly adopt a switch to control the unlatching of transport pipe and return tube simultaneously or close, use very convenient; Petrol engine work meeting raises the fuel oil temperature in the fuel tank inner chamber gradually, thereby the fuel oil temperature in the inflow Carburetor also can raise gradually, after petrol engine is out of service, fuel oil temperature in the fuel tank inner chamber slowly descends, air pressure in the process intermediate fuel oil case that its temperature descends also reduces thereupon gradually, therefore between fuel tank and Carburetor, form pressure difference, the fuel oil of retaining in the Carburetor is back in the fuel tank under this action of pressure automatically, need not manually to turn bolt can emit above-mentioned trapped fuel, has realized retaining in the Carburetor the automatic backflow of fuel oil; The utility model is arranged at the fuel oil throw over switch at the place that is communicated with of transport pipe and return tube, breathing pipe is communicated with the back with the fuel oil throw over switch and communicates with atmosphere, and the transport pipe and the breathing pipe that are close to described fuel oil throw over switch place are arranged in parallel, close return tube when having realized opening transport pipe and breathing pipe, otherwise, when opening return tube, close transport pipe and breathing pipe, promptly adopt the packet type switch valve to control transport pipe, breathing pipe and return tube simultaneously, it is simple in structure, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation sketch of gasoline engine fuel oil-way system among the utility model embodiment 1;
Wherein, part 1 is a fuel tank, and part 2 is a transport pipe, and part 3 is a Carburetor, and part 4 is the fuel oil throw over switch, and part 5 is the mouth of draining the oil, and part 6 is a return tube, and part 7 is a breathing pipe.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but therefore the utility model is not limited among the following concrete mode.
Embodiment 1: as shown in Figure 1, a kind of gasoline engine fuel oil-way system, the Carburetor 3 that comprises the fuel tank 1 that has closed fuel tank lid, is communicated with fuel tank 1 by transport pipe 2 and be arranged at fuel oil throw over switch 4 on the transport pipe 2, wherein, the bottom of Carburetor 3 is provided with the mouth 5 of draining the oil, and also is provided with return tube 6 between Carburetor 3 and the fuel tank 1; Transport pipe 2 is cross intercross arrangement with return tube 6 and is communicated with; Fuel oil throw over switch 4 is arranged at transport pipe 2 and is communicated with the place with return tube 6; The top of fuel tank 1 is provided with vent and breathing pipe 7; One termination of this breathing pipe 7 is gone into vent and is communicated with the inner chamber of fuel tank 1, and the other end is communicated with the back with fuel oil throw over switch 4 and communicates with atmosphere; The transport pipe 2 at next-door neighbour's fuel oil throw over switch 4 places is arranged in parallel with breathing pipe 7, controls the open and close of transport pipe 2 and breathing pipe 7 simultaneously to realize fuel oil throw over switch 4; One end of return tube 6 is communicated with the mouth 5 of draining the oil of Carburetor 3, and the other end is communicated with the top of fuel tank 1.
Rotation fuel oil throw over switch 4 is to open transport pipe 2 and breathing pipe 7, close return tube 6 simultaneously, this moment, the inner chamber of fuel tank 1 communicated with atmosphere by breathing pipe 7, the pressure that has guaranteed fuel tank 1 inner chamber equates with atmospheric pressure, thereby the smooth and easy inflow Carburetor 3 of the fuel oil energy in the fuel tank 1, petrol engine can normally start; After petrol engine is out of service, rotation fuel oil throw over switch 4 is to open return tube 6, close transport pipe 2 and breathing pipe 7 simultaneously, automatically be back in the fuel tank 1 by return tube 6 under the action of pressure of fuel oil between fuel tank 1 and Carburetor 3 that retain in the Carburetor 3 this moment, thus the automatic backflow of retaining fuel oil in the realization Carburetor 3.
