Description
Technical field
The utility model relates to a kind of carburetor structure, relates to PD25J-07 type Carburetor.
Background technique
Carburetor (carburetor) is under the vacuum action of engine operation generation, by the mechanical device that a certain proportion of gasoline mixes with air.Carburetor is as a kind of mechanical device of precision, and it can be referred to as " heart " of motor to the important function of motor.Its complete device should comprise starting arrangement, idling device, moderate duty device, full load device, accelerating unit.Carburetor can according to the different operating status requirements of motor, and automatic mixing goes out corresponding concentration, exports the mixed gas of corresponding amount, and what mix to make the mixed gas allotted is relatively more even, and Carburetor also possesses the effect making fuel-oil atmozation, normally runs for machine.In order to make Carburetor high-efficient atomizing light a fire with efficient, the valve member in needing control to be atomized and ignition part, therefore how installing in order to the sensor of regulation and control and the position of ignition part is the object that the utility model is studied.
Model utility content
In order to solve existing technical deficiency, the utility model provides a kind of carburetor structure.
The technical solution of the utility model is:
A kind of carburetor structure, comprise carburetor main body, it is characterized in that: the housing of described carburetor main body is provided with one in order to be connected to the lambda sensor body on vehicle ECU, the inductive head of described lambda sensor is arranged on tail gas discharging pipe place, the housing of described carburetor main body is also provided with the heater assembly that firing head is positioned at engine compartment, the housing of described carburetor main body is also provided with the rocker arm assembly, the manual upgrading valve that control by vehicle ECU.
Wherein, the housing of described carburetor main body is provided with a bolt hole, and described lambda sensor body is connected and fixed by the bolt hole on bolt and housing.
Described heater assembly is fixedly connected with the tapped hole on the housing of carburetor main body by outside thread.
The housing of described carburetor main body is also provided with guy wire support.
The housing of described carburetor main body is also provided with curved oil inlet pipe and straight shape short covering gas repay pipe.
The utility model has the advantage of: the utility model structure is simple, and it is reasonable, convenient that position is installed, realize the guarantee to Carburetor high-efficient atomizing and engine high-efficiency igniting in conjunction with locomotive control unit ECU, meet user demand.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment perspective view one,
Fig. 2 is the utility model embodiment perspective view two.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Referring to figs. 1 to Fig. 2, the utility model relates to a kind of carburetor structure, comprise carburetor main body 1, the housing of described carburetor main body is provided with one in order to be connected to the lambda sensor body 2 on vehicle ECU, the inductive head of described lambda sensor is arranged on tail gas discharging pipe place, the housing of described carburetor main body is also provided with the heater assembly 3 that firing head is positioned at engine compartment, the housing of described carburetor main body is also provided with the rocker arm assembly 4, the manual upgrading valve 5 that control by vehicle ECU.Make the sensor that increases newly and heater assembly be installed on Carburetor, reduce the impact of installing equipment of other positions of vehicle.
In order to be connected firmly, the housing of above-mentioned carburetor main body is provided with a bolt hole, and described lambda sensor body is connected and fixed by bolt 6 and the bolt hole on housing.
Convenient in order to install, above-mentioned heater assembly is fixedly connected with the tapped hole on the housing of carburetor main body by outside thread.
The housing of above-mentioned carburetor main body is also provided with guy wire support 7.
In order to coordinate vehicle needs, the housing of above-mentioned carburetor main body is also provided with curved oil inlet pipe 8 and straight shape short covering gas repay pipe 9.
Specific implementation process:
Increase the effect of lambda sensor and heater assembly:
According to the change of oxygen content in exhaust, determine the air fuel ratio value entering engine chamber mixed gas, to ECU after error signal is amplified, the target air-fuel ratio value of the signal sets of input ECU compares, control fuel injection quantity by ECU, air fuel ratio is remained near the desired value of setting, makes fuel oil Thorough combustion, good operating stability, antijamming capability is strong.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
