In the starting process of the engine, when the the negative pressure in the negative pressure valve is not enough, the auxiliary fuel tank can provide enough fuel oil to the carburetor, the quick and normal starting of the engine is guaranteed, and the problems that the engine of a low fuel tank of a motorcycle is difficult to be started or can not be started are effectively solved. Furthermore, a first time fuel oil use filler is arranged on the upper portion of the auxiliary fuel tank, and the quick start of the engine is guaranteed when the fuel oil is used for the first time.

Description

The fuel tank position is lower than the motorcycle oil supply system of Carburetor
Technical field
The utility model relates to the motorcycle oil supply system, is specifically related to the oil supply system that a kind of fuel tank position is lower than Carburetor, is specially adapted to pedal motorcycle and uses.
Background technique
For pedal motorcycle, be subjected to structure and space arrangement constraints, the position of its fuel tank can be lower than Carburetor.Fuel tank position as shown in Figure 1 and Figure 2 is lower than the motorcycle oil supply system of Carburetor, is comprised of fuel tank 1, motor 2, air-strainer 3, Carburetor 4, negative pressure valve 5 etc.Carburetor 4 is connected between air-strainer 3 and the engine air inlet tube 6, fuel tank 1 links to each other by fuel tank oil outlet tube 7 with negative pressure valve 5, negative pressure valve 5 links to each other by Carburetor oil inlet pipe 8 with Carburetor 4, negative pressure valve 5 links to each other by negative tube 9 with engine air inlet tube 6, and the position of fuel tank 1 is lower than Carburetor 4.By negative pressure valve 5 fuel oil in the fuel tank 1 is taken out highly to Carburetor 4, is mixed with gas after filtering through air-strainer 3, the interior pressure of engine air inlet tube 6 was less than barometric pressure when the power of negative pressure valve 5 work came from motor 2 running.
When motor 2 ran well, the degree of vacuum in the engine air inlet tube 6 was high, and negative pressure valve 5 normal operations can continuously to Carburetor 4 fuel feeding, make motor 2 normal operations.But when motorcycle starting, because the rotating speed of motor 2 is low, the degree of vacuum in the engine air inlet tube 6 is not high, and negative pressure valve 5 can't work, and enough fuel oils can not be evacuated to Carburetor 4; In addition, when motorcycle parking, have the part fuel evaporation to reveal in the Carburetor 4, pasta is lower in Carburetor 4 float chambers, causes mixture strength low, and motor 2 is difficult to starting or can't starts at all.
The model utility content
The utility model is lower than this class motorcycle of Carburetor specially for the position of fuel tank, when negative pressure is inadequate in negative pressure valve, enough fuel oils can't be evacuated to Carburetor, causes the technical problem that motor can't normal starting.
For this reason, a kind of fuel tank position that the utility model provides is lower than the motorcycle oil supply system of Carburetor, comprise fuel tank, motor, air-strainer, Carburetor and negative pressure valve, described Carburetor is connected between air-strainer and the engine air inlet tube, described fuel tank links to each other by the fuel tank oil outlet tube with negative pressure valve, negative pressure valve links to each other by the Carburetor oil inlet pipe with Carburetor, negative pressure valve links to each other by negative tube with engine air inlet tube, and the position of fuel tank is lower than Carburetor, key is: be provided with service tank on the described Carburetor oil inlet pipe, described service tank links to each other with fuel tank by the service tank return tube, and the position of service tank is higher than Carburetor.
Its working principle is: when engine work, service tank can be stored fuel oil, in the engine start stage, before negative pressure valve can't work fully, service tank can provide enough fuel oils to Carburetor, guarantee the indoor fuel head of carburettor float, make mixed gas have enough concentration to pilot engine.Behind engine work, it is normal that the work of negative pressure valve also is tending towards, can provide enough fuel oils to Carburetor continuously, and the excess consumption when replenishing starting to service tank, the unnecessary fuel oil that pumps into from negative pressure valve can flow back to fuel tank by return tube, keeps the constant pressure of this oil supply system.
Be preferably, above described service tank, be provided with first use fuel oil feeding port.When motorcycle uses for the first time, fill with even fuel tank added, can not be full of immediately fuel oil in the service tank yet, at this moment, and can be by the first fuel oil man filler fuel up in the service tank that uses, can quick starting when guaranteeing to use for the first time.When motorcycle is parked for a long time, all fuel oils in the car need to be put driedly, when resetting, also need fuel up in the service tank.
Beneficial effect: by increasing service tank and service tank return tube in the motorcycle oil supply system that is lower than Carburetor in the fuel tank position, in the engine start process, negative pressure in negative pressure valve is inadequate, in the time of enough fuel oils can't being evacuated to Carburetor, service tank can provide enough fuel oils to Carburetor, to guarantee quick, the normal starting of motor, efficiently solves the problem that low fuel tank motorcycle engine starting difficulty maybe can't be started, simple in structure, novel, and effect is remarkable.
