Description
Technical field
The invention belongs to motorcycle carburetor making-up air device technical field, be specifically related to a kind of motorcycle carburetor hand-control mechanical automatic formula making-up air device.
Background technique
The sky that the common motorcycle carburetor of prior art exists air and gasoline fires the deficiency that proportions of ingredients can not reach perfect condition, gasoline can not just be discharged from outlet pipe by Thorough combustion, cause the high and wasting of resources of oil consumption, and the gaseous contaminant that outlet pipe is discharged, as too high in carbon monoxide, hydrocarbon and nitrogen oxide large pollution is brought to environment, there is multinomial corrective measure though have for this deficiency, but there is such-and-such defect.Such as common electronic controlled carburetor, by electronic control tonifying Qi, primarily of electronic component and electrical part composition, it exists, and cost is relatively high, rate of fault is not also grown and is not easy the deficiency of maintenance high, working life, must be that professional workforce could repair when going wrong.
As China Patent No. 201120293199.3, name is called the utility model patent of " electronic controlled carburetor ", disclose a kind of electronic controlled carburetor, comprise carburetor main body, also comprise temperature transducer, lambda sensor, electric controller and solenoid valve, described temperature transducer, lambda sensor and solenoid valve are all connected to electric controller, and described solenoid valve is also connected to carburetor main body.The feature of this electronic controlled carburetor is application electromagnetic valve air inflow, solenoid valve normally can work and must have temperature transducer, the sensors such as lambda sensor gather relevant information and are supplied to electric controller, control signal Controlling solenoid valve is exported again through electric controller computing, through so many controlling unit, real-time control effects is reduced, rate of fault increases, especially the electromagnetic coil in solenoid valve, this is also regarded as the components and parts that rate of fault is high and the life-span is short in component of machine, as for the complexity of electric controller, layman is made to be difficult to start to keep in repair it.
And for example China Patent No. 200910190686.4, the patent of invention that name is called " novel electronic control carburetor electromagnetic valve and the installation interface technology with electronic controlled carburetor thereof ", disclose a kind ofly provides a kind of new airflow controlled magnetic valve namely to claim electronic control carburetor electromagnetic valve in petrol engine carburetor automatically controlledization integrated system, for the ease of the installation of solenoid valve on electronic controlled carburetor, be convenient to solenoid valve can reliablely and stablely work in running at petrol engine and motor vehicle, further improve the internal structure of solenoid valve, and the Placement of solenoid valve inner piece, and the Placement of solenoid valve and Carburetor, the computational methods of the range of a set of comparatively perfect interface mounting technique and movable iron core of electromagnetic valve motion are innovated.This invention is not only by the relatively high electromagnetic valve of rate of fault, also propose in the multiple Placement described in it in claim 1 especially, no matter any Placement, all must ensure that electromagnet is working perpendicular in substantially horizontal as far as possible, this is very unapproachable in fact, because whole device is fixed on Motor Vehicle, Motor Vehicle under steam, there is a variety of causes such as climb and fall, Uneven road, vehicle vibration due to road, make this requirement be difficult to reach.
Above-mentioned two routine patents also exist can not meet air compensation curve and engine speed fuel delivery Curve Matching requirement to set the deficiency of air supply passage sectional area Changing Pattern rightly.
Summary of the invention
The technical issues that need to address of the present invention are, overcome existing motorcycle carburetor making-up air device exist or control piece moving resistance large tonifying Qi speed to working conditions change reflection insensitive, or adopt air pump to add solenoid valve, increase load, frequent starting, the defect that complex structure cost is high and volume and weight is large, provide the mechanical type motorcycle carburetor making-up air device of the superior performance that a kind of structure is simple, easy to adjust, processing ease, air compensation curve mate with engine speed fuel delivery.
