Description
The utility model relates to engine and carburetor, particularly engine and carburetor of motorcycle.
Motorcycle relates to safety reliability and dynamic economics as the traffic tool.The factor that influences power character and Economy is a lot, but wherein main factor is the Carburetor of motorcycle engine, directly has influence on the power character and the Economy of motorcycle.What at present, XF250 type motorcycle series was joined is the 1F65E motor.The main two big problems that exist: the one, adjust the control difficulty, the 2nd, exhaust emission is serious.Tracing it to its cause is the unreasonable structure of Carburetor, has following point:
1, the carburetor structure complexity, the product manufacturability is poor, and performance inconsistency is big, instability.
2, mixing chamber, float chamber master nozzle block is linked to each other by fastening piece, therefore, poor reliability, easy to leak.
3, Carburetor is connected with motor, adopts transitional flange, the anchor ear form, and this Placement is easy to generate gas leakage.
4, idle metering jet and transitional pore are placed on the main nozzle block, can't adjust the control difficulty.
5, main oil system, idling oil system and air flue are non-independent the setting, have the phase mutual interference to adjust difficulty, therefore, just are difficult to the control idling or than the air fuel ratio (A/F) of low speed, can't supply with most economical mixed gas.Main oil system is except idling and minimum load condition, and system all works at other operating mode master fuel feeding, because non-independent the setting, the phase mutual interference causes the engine performance fluctuation unstable.
6, the cold starting difficulty adopts the oil gun oily plane that raises, the enriching starting, and air fuel ratio (A/F) is difficult to control, is not that overrich was exactly rare, causes starting difficulty.
7, because above device is unreasonable, motor can't be worked under most economical operating mode, therefore, the speed of a motor vehicle (50-70 kilometer/hour) oil consumption commonly used is big, and average fuel consumption is greater than 2.8 liters/hundred kilometers.
Comprehensive above-mentioned various factors all will influence air fuel ratio, and promptly mixed gas is not to burn under optimum, and incomplete combustion directly influences engine power performance and Economy, and exhaust emission is serious, influences environmental hygiene and life health.
The purpose of this utility model is to design a kind of rational in infrastructure, adjusts easily, and stable performance, power character and Economy all are applicable to the Carburetor of XF250 type motorcycle 1F65E motor.
Another purpose of the present utility model is to increase the Carburetor peak output, the Maximum Torque that design than former Carburetor, minimum specific fuel consumption, and common economic speed of a motor vehicle oil mass reduces than former Carburetor, makes discharging meet NBS.
The utility model purpose again is the Carburetor that designs to adopt independently automatic start excess fuel device, makes engine start easy.
The technical solution of the utility model is:
1, taper mutation spindle fuel-economizing Carburetor links flange by the Carburetor body, the mixing chamber loam cake, and the float chamber loam cake, and be arranged on intrinsic mixing chamber, and closure, float chamber, main oil system and air flue, idling oil system and air flue, automatic start excess fuel device is formed.
2, newly-designed carburetor bowl and mixing chamber unite two into one, and make the two place the Carburetor body portion to cancel main nozzle block, good reliability.
3, the cancellation counter flange, the Carburetor flange directly is connected with motor, is provided with adiabatic gum headblock and O RunddichtringO in the joint, reaches Carburetor and gas leak phenomenon to reduce the motor heat.
4, the monomer idle metering jet is set and adjusts screw, can regulate flow size makes and adjusts control easily, but supply engine idling and best mixed gas during than low speed, and interference-free, stable performance when making motor in idling with than low speed.
5, main oil system and air flue, idling oil system and air flue are absolute version, do not have mutual interference effect, the effect that main fuel feeding is is when the medium and small load condition of motor, supplies with most economical mixed gas, main oil system and air flue is set separately can gets rid of interference, reaches the fuel-economizing purpose.
6, the closure plunger changes down the back cover form into, makes the smooth-going smoothness of air-flow, and gasoline air mixture ratio (A/F) is good, and it is perfect to burn, and blowdown is few.
7, adopt independent automatic start excess fuel device, the cold starting air fuel ratio is controlled easily, starting is easily.
The utility model has the advantages that:
1, structure is rationally advanced, and gas leak of the oil leakage is few, and good reliability is adjusted control easily, stable performance.
2, peak output, Maximum Torque increases, and is suitable for assembling XF250 type motorcycle 1F65E motor.
3, the common economic speed of a motor vehicle (50-70 kilometer/hour) oil consumption (is seen accompanying drawing 6) than former Carburetor reduction more than 10%.
4, the improvement of oil-feed system has improved the oil-feed sealing greatly, improves the leakage of oil disadvantage.
5, reduced discharge amount, make discharging meet NBS.
