Abstract
The utility model relates to the field of automobile engines, in particular to a carburetor type gasoline fuel feeding system. The outlet-control carburetor type gasoline fuel feeding system comprises a gasoline tank, a gasoline filter, a gasoline pump, an air filter and a carburetor. The gasoline tank is communicated with the carburetor through an oil delivery pipe. The gasoline filter and the gasoline pump are connected in series on the oil delivery pipe in sequence. The air filter is communicated with an air inlet of the carburetor through an air inlet pipe. An oil nozzle of the carburetor is communicated with a gas inlet of a steam cylinder. An exhaust opening of the steam cylinder is communicated with an exhaust pipe. A flow meter is arranged at an inlet of the air filter. The air inlet pipe and the oil delivery pipe are both connected into a proportional valve in series. Flow of the air inlet pipe and the oil delivery pipe is controlled by the proportional valve. According to the carburetor type gasoline fuel feeding system, air inlet amount and output amount of fuel are controlled through the proportional valve in proportion, so that the air-fuel ratio of mixed fuel gas which finally flows into the steam cylinder is approximately controlled, efficiency of an engine is guaranteed, and emission of poisonous and harmful waste gas is lowered.
Description
Technical field
The utility model relates to the motor car engine field, relates in particular to a kind of carburetor type Fuel Petroleum supply system.
Background technique
Usually the fuel supply system of car engine is divided into Fuel Petroleum supply system and diesel fuel supply system two classes according to fuel used classification; And the Fuel Petroleum supply system is divided into two kinds of carburetor type and fuel jet types.The Main Function of fuel supply system is to supplying with pure air in cylinder, and, according to the need of work of motor, sends into quantitative fuel in cylinder on time, to regulate engine output and rotating speed, last, the waste gas after burning is discharged cylinder.
Be wherein, by Carburetor, gasoline atomizing and air are mixed to form inflammable mixture in the carburetor type fuel supply system, then send as each cylinder.When gasoline by the float chamber in gasoline pumping such as Carburetor, there is an amount empty in float chamber, it can be poor by ambient atmos pressure and jet pipe mineralization pressure, directly oil is sprayed into and shouts pipe, become oil droplet and shout the air of pipe top by air-strainer and mix, some under the various operating modes such as engine start, cold start-up, acceleration, idling, normal operation and the inflammable mixture of concentration are provided.Scientist thinks that 1 kilogram of gasoline perfect combustion approximately needs 14.7 kg of air per kg of water evaporated, be that air fuel ratio is 14.7: 1, the mixed gas of this air fuel ratio is called normal mixture, motor is most effective at this moment, the poisonous and hazardous waste gas of discharging is also minimum, because this numerical value is difficult to realize in practice, so be called again " theoretical mixture gas ".Air fuel ratio is greater than the weak mixture that is called of normal mixture, the rich mixture that is called less than normal mixture, because change in concentration and the load variations of motor under various operating conditionss of mixed gas is closely related, existing Carburetor is difficult to meet this proportion requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of carburetor type Fuel Petroleum supply system of control of export, native system is controlled the air inflow of air and the output quantity of fuel oil in proportion by a Proportional valve, roughly control air fuel ratio, guarantee the efficiency of motor, and reduce the discharging of toxic harmful exhaust gas.
The utility model is achieved in that a kind of carburetor type Fuel Petroleum supply system of control of export, comprise petrol tank, gasoline filter, petrol pump, air-strainer and Carburetor, described petrol tank is communicated with Carburetor by transport pipe, and described gasoline filter and petrol pump are in sequential series on transport pipe; Described air-strainer is communicated with the suction port of Carburetor by suction tude, the jet of described Carburetor is communicated with the suction port of cylinder, the relief opening of described cylinder is communicated with outlet pipe, flowmeter is equipped with in the ingress of described air-strainer, suction tude is all connected into Proportional valve with transport pipe, by the flow of proportional valve control suction tude and transport pipe.
In the middle part of described suction tude, one section is corrugated flexible hose.
Also be in series with baffler on described outlet pipe.
Described baffler is S drum type baffler, interior back pressure baffler or G type baffler.
The carburetor type Fuel Petroleum supply system of the utility model control of export is controlled the air inflow of air and the output quantity of fuel oil in proportion by a Proportional valve, make the air fuel ratio that finally flow into the combination gas in cylinder roughly to be controlled at 14.7: 1, guarantee the efficiency of motor, and reduce the discharging of toxic harmful exhaust gas.
Description of drawings
Fig. 1 is the structural representation of the carburetor type Fuel Petroleum supply system of the utility model control of export.
In figure: 1 petrol tank, 2 gasoline filters, 3 petrol pumps, 4 air-strainer, 5 Carburetors, 6 transport pipe, 7 suction tude, 8 cylinders, 9 outlet pipes, 10 Proportional valves, 11 bafflers, 12 flowmeters.
