Description
Technical field
The utility model relates to a kind of novel PD25J2-06 Carburetor.
Background technique
Existing, PD25J2-06 Carburetor, structure is comparatively simple, function singleness, and fuel oil often can not get Thorough combustion, causes fuel oil to waste and befouling environment, poor work stability.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of novel structure, good operating stability, ensures the clean-burning novel PD25J2-06 Carburetor of fuel oil.
The utility model adopts following scheme to realize: a kind of novel PD25J2-06 Carburetor, comprise carburetor body, the outer side described carburetor body being positioned at suction tude is provided with the sensor gathering tail gas carbon monoxide content, and described sensor is connected with offgas duct by tracheae; Described carburetor body is also provided with air block valve, described carburetor body is also provided with the L-type oil inlet pipe communicated with the float chamber be positioned at bottom carburetor body.
Further, described carburetor body is also provided with expander to expand with heat and contract with cold and control the electric enrichment valve of enriching oil circuit break-make.
Further, tilting ellipticity closure is provided with in described suction tude, carburetor body is provided with the rocking arm that throttle plate pin drives closure to rotate, the other end end relative with rocking arm of throttle plate pin be located at by described sensor, described rocking arm is controlled to rotate by bracing wire, described rocking arm offering two-wire groove, described carburetor body is also provided with guy wire support, described guy wire support offering the double flute mouth in order to being drawstring through.
Further, described carburetor body is also provided with the position transducer responding to throttle position, described sensor is fixed on carburetor body by screw lock, and described sensor is connected with central unit respectively with position transducer.
Compared with prior art, the utility model has following beneficial effect: this novel PD25J2-06 Carburetor can according to the change of carbon monoxide content in exhaust, determine the air fuel ratio value entering engine chamber mixed gas, fuel injection quantity is controlled by central unit ECU, air fuel ratio is made to remain near the desired value of setting, make fuel oil Thorough combustion, good operating stability, antijamming capability is strong.Can prevent from, because rare engine power deficiency and automatically extinguishing of causing appearred in combustion mixed gas, burning away after preventing not clean-burning inflammable mixture from entering baffler simultaneously simultaneously, even can cause baffler and blow out the sound.
For making the purpose of this utility model, technological scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the utility model will be described in further detail.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment constructs front view;
Fig. 2 is that the utility model embodiment constructs rear view;
Number in the figure illustrates: 1-carburetor body, 2-suction tude, 3-sensor, 4-air block valve, 5-rocking arm, 6-wire casing, 7-guy wire support, 8-notch, 9-L type oil inlet pipe, 10-float chamber, 11-electric enrichment valve.
Embodiment
As shown in Figure 1 and 2, a kind of novel PD25J2-06 Carburetor, comprise carburetor body 1, the outer side described carburetor body 1 being positioned at suction tude 2 is provided with the sensor 3 gathering tail gas carbon monoxide content, and described sensor 3 is connected with offgas duct by tracheae; Described carburetor body 1 is also provided with the position transducer responding to throttle position, and described sensor 3 is fixed on carburetor body 1 by screw lock, and described sensor and position transducer are connected with central unit ECU respectively.According to the change of carbon monoxide content in exhaust, determine the air fuel ratio value entering engine chamber mixed gas, central unit ECU is flowed to after error signal being amplified, the signal of input central unit ECU and the target air-fuel ratio value of setting compare, control fuel injection quantity by central unit ECU, air fuel ratio is remained near the desired value of setting, makes fuel oil Thorough combustion, good operating stability, antijamming capability is strong.
In the present embodiment, described carburetor body 1 is also provided with air block valve 4, can prevent motorcycle from running at high speed, carrying out anxious deceleration in a flash, carburetor throttle scram, motor is still running up under the effect of inertia, there is rare phenomenon in the inflammable mixture that now Carburetor produces, inflammable mixture velocity of combustion is slow, engine power will be caused not enough and automatically extinguishing, burn away after preventing not clean-burning inflammable mixture from entering baffler simultaneously, even can cause baffler and blow out the sound.
In the present embodiment, described carburetor body is also provided with the L-type oil inlet pipe 9 communicated with the float chamber 10 be positioned at bottom carburetor body.
In the present embodiment, described carburetor body 1 is also provided with expander and expands with heat and contract with cold and control the electric enrichment valve 11 of enriching oil circuit break-make, enriching oil circuit is connected with mixed gas suction tude.When engine rotation, magnetogenerator produces electricity makes heating unit heat, and the heat that heating unit produces makes expander (as rod wax) expanded by heating extend and promotes plunger closedown enriching oil circuit, and when motor does not work, plunger opens enriching oil circuit under the action of the spring.
In the present embodiment, tilting ellipticity closure is provided with in described suction tude 2, carburetor body 1 is provided with the Rocker arm 5 that throttle plate pin drives closure to rotate, simultaneously in order to prevent contamination by dust throttle plate pin, the other end end relative with Rocker arm 5 of throttle plate pin be located at by described sensor 3; Described Rocker arm 5 is controlled to rotate by bracing wire, described Rocker arm 5 offering two-wire groove 6, described carburetor body 1 is also provided with guy wire support 7, described guy wire support 7 offering the double flute mouth 8 in order to being drawstring through, the bracing wire demand of both direction can be met, easy to use.
Above-listed preferred embodiment; the purpose of this utility model, technological scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
