Description
Technical field
The utility model relates to the Component of motorcycle oil supply system, relates in particular to a kind of novel Carburetor of using electronic control technology.
Background technique
Environmental pollution and energy shortage have become two big crises of the world today, are seriously threatening the existence of whole human society, so green technology and power-saving technology have become the problem of a sternness.Along with human living standard's raising, people's environmental consciousness improves constantly, and the minimizing day by day of petroleum resources in addition makes people all have higher requirement to Economy, exhaust index and the driving comfortability of motorcycle.
The work system of general Carburetor is divided into: main oil system 2, low speed oil are 3, starting system etc.Technology emphasis wherein is to satisfy under the prerequisite of environmental regulation, and main oil system 2, low speed oil are 3 to provide good characteristic of fuel delivery, satisfy motor under different operating modes required combustion gas mixing than and fuel feed.As shown in Figure 1, the main oil system of Carburetor is made up of body related channel program, main spindle 21, main jet pipe 22, main foam tube 23, main jet 24, primary air metering-orifice 25 and main oil system master air vent 26 (see figure 2)s, mainly bears the characteristic of fuel delivery requirement under the big-and-middle load condition service condition of motor.(as shown in Figure 1) the low speed oil of Carburetor is 3 to be made up of body related channel program, idle metering jet 31, transition oil outlet 32, idling oil outlet 33, idle spiral shell pin 34, idling air jet 35, idling master's air vent 36 and idling bypass air flue 37 (seeing accompanying drawing 2), mainly bears the characteristic of fuel delivery requirement under the operating mode service conditions such as zero load little load such as engine idle, transition.In addition, when throttle is lost in high engine speeds running, for example: the anti-forced idling mode that drags engine running of motorcycle the etc. when decelerating mode when running at high speed, descending.Closure has been got back to the position of idling, and motor still runs up, and has only idling oil outlet fuel feeding, forms rare partially mixed gas, produces to vow fire and flame-out phenomenon, and mixed gas after-burning when serious produces the strong sound of blowing out in baffler.Maximum consequence is to produce a large amount of carbon monoxide (CO) and hydrocarbon (HC), contaminated air in the exhaust.In order to address this problem, general Carburetor has increased air cutoff valve (ACV) system in the low speed oil supply system.As shown in Figure 2, low speed oil supply system intake duct is made up of idling master air vent and idling bypass air flue, and idling bypass air flue is controlled by air cutoff valve (ACV) 7` system.Air cutoff valve (ACV) 7` system is made up of Carburetor body 1, air cutoff valve (ACV) diaphragm 71`, air cutoff valve (ACV) lid 72`, return spring 73`, piston 74`.Nominal situation two passages give the low speed oil supply system for air simultaneously.When taking place suddenly to lose the throttle operating mode, suction function behind the closure is to air cutoff valve (ACV) diaphragm, air cutoff valve (ACV) diaphragm overcomes the elastic force of return spring, move on the piston and block idling bypass air flue, compensated with air amount in the low speed oil system reduces, in the idling oil outlet, spray denseer fuel mixture, avoid motor to vow fire and flame-out phenomenon.
In the using process of reality, the motorcycle driving operating mode is very complicated: cold starting, idling, acceleration, deceleration, descending, upward slope etc.Carburetor provides required air fuel ratio for each operating mode.This traditional mechanical formula structure Carburetor, for a certain specific operation, air fuel ratio is fixed.If change its numerical value, must adjust structural parameter.But the adjustment of structural parameter certainly will influence the air fuel ratio of other operating mode.Therefore, the fixing structural parameter of this Carburetor can not satisfy the needs of each operating point fully, must take all factors into consideration.Factory reaches EUROIII Emission Standard in order to make exhaust emissions, and each operating point air fuel ratio is generally all rare partially, must sacrifice power character and driving comfortability.If will make Carburetor 100% discharging of producing reach EUROIII Emission Standard, power character and good economy performance must propose very high requirement to the precision of the main ingredients element of Carburetor, just present level of processing, the part of producing does not reach permissible accuracy, and has certain scattered error.
