Abstract
The utility model relates to the field of automobile engine, in particular to a carburetor type gasoline fuel supply system. The carburetor type gasoline fuel supply system capable of precisely controlling the air-fuel ratio 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 a gasoline pipe. The gasoline filter and the gasoline pump are sequentially connected on the gasoline pipe in series. The air filter is communicated with a gas inlet of the carburetor through a gas inlet tube. An oil spray opening of the carburetor is communicated with a gas inlet of an air cylinder. An exhaust outlet of the air cylinder is communicated with an exhaust pipe. A flowmeter is arranged on the gas inlet pipe. A gas inlet branch pipe is arranged on the air cylinder. A solenoid valve is arranged on the gas inlet branch pipe. According to the carburetor type gasoline fuel supply system, the gas inlet branch pipe is used for replenishing mixed fuel gas sent into the air cylinder through the carburetor, so that the air-fuel ratio is precisely controlled, the efficiency of an engine is ensured, and emission of poisonous and harmful waste gas is reduced.
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 accurate control air fuel ratio, native system has connected again the arm of a fine adjustment air inflow on cylinder, make air fuel ratio accurately be controlled at 14.7: 1, 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 accurate control air fuel ratio, 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, on described suction tude, flowmeter is housed, on described cylinder, air intake branch is housed, on described air intake branch, solenoid valve is housed.
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 that the utility model is accurately controlled air fuel ratio has connected again the arm of a fine adjustment air inflow on cylinder, the combination gas of Carburetor being sent into cylinder by air intake branch supplements, make air fuel ratio accurately be controlled at 14.7: 1, guarantee the efficiency of motor, and reduce the discharging of toxic harmful exhaust gas.
