Abstract
The utility model relates to an adjustable air metering orifice of a carburetor, which comprises a metering orifice main body provided with an air passage, wherein, a cone-shaped regulating screw rod is arranged in the metering orifice main body, and the cone-shaped regulating screw rod can axially move corresponding to the air passage. The utility model has simple structure, easy fabrication and installation and convenient adjustment, can satisfy the requirement of rated air quantity of engines of different specifications and same model, and can increase optimum proportion of oil and gas of the mixed fuel fed by the carburetor. The goal of fuel saving, improvement of power output effect of the engine and the decrease of pollution is achieved, and the service life of the carburetor is effectively prolonged.
Description
The utility model relates to a kind of motor car engine Carburetor air bells conditioner, particularly a kind of adjustable air jet that improves the Carburetor atomizing effect.
Existing Motor Vehicle such as motor car engine with or motorcycle engine with the air jet of Carburetor, be fixed, determine by its fixing aperture fully by the air quantity of metering-orifice.When having on the motor that the fixing Carburetor of metering-orifice is contained in same model different size, because each engine output power is variant, so its fuel consumption is also different with required air quantity, so the motor of same model different size can't adopt the Carburetor with a kind of specification, Carburetor and motor do not match, and will have a strong impact on efficiency of engine and cause certain environmental pollution.In addition, in the air-strainer using process of motor, often the aperture is diminished or stop up because of the filtering hole laying dust, thereby change the air jet Throughput, cause motor to can not get best oil gas mixing ratio, influence firing effect, weaken the power output of motor, not only increase fuel consumption, but also can not fully burn, cause certain environmental pollution because of fuel oil.
The purpose of this utility model provides a kind of Carburetor adjustable air metering-orifice, it is simple in structure, make and install easily, easy to adjust, can satisfy the needs of the motor of same model different size, improve the best gas oil ratio of fuel that Carburetor is supplied with, reach fuel-economizing, improve the engine power output effect specified air quantity, reduce the purpose of environmental pollution, effectively prolong Carburetor working life.
The purpose of this utility model is achieved in that this device comprises the metering-orifice body that has air passageways, wherein has in the metering-orifice body with respect to the axially movable taper adjusting screw rod of air passageways.
Because the utility model is that an integrated type or split type metering-orifice body are installed in the fixedly metering-orifice (main oil system air jet or idle system air jet) of existing Carburetor, the taper adjusting screw rod is set in the metering-orifice body again, utilize moving axially of adjusting screw rod, change the sectional area of air passageways, control is through the air quantity of air passageways, so can satisfy same model different size motor to the desired maintenance optimum oil of Carburetor, gas be mixed than air quantity, to reach best fuel atomization effect and oil, the gas ratio that is mixed, the power output that improves motor.This device is not only simple in structure, manufacturing is installed easily, and uses adjustment also very convenient.Therefore can reach fuel-economizing fully, improve the engine power output effect, reduce the purpose of environmental pollution.In addition, when Carburetor has foreign matter to influence rate of air circulation at air-strainer, suitably adjust adjusting screw rod, enlarge the sectional area of air passageways, still can guarantee provides enough air quantities to motor, and makes oil, gas mixed gas keep best proportioning, thereby prolongs Carburetor working life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model I type concrete structure schematic representation.
Fig. 2 is the utility model II type concrete structure schematic representation.
Fig. 3 is the user mode figure that is used for the motor car engine Carburetor.
Fig. 4 is the user mode figure that is used for engine and carburetor of motorcycle.
Describe concrete structure of the present utility model in detail according to Fig. 1-4.This device comprises metering-orifice body 2 and its interior taper adjusting screw rod 1 of assembling that has air passageways 3, screw rod 1 can move axially with respect to air passageways 3, this device is made two kinds on I type structure and II type structure as required, is installed in respectively on the corresponding position of Carburetor.Wherein the body 2 of I type structure is an integrated type, and promptly the adjustment screw thread of taper adjusting screw rod 1 is combined as a whole (as shown in Figure 1) with the metering-orifice body 2 that has air passageways 3.The body 2 of II type structure is split type, and promptly the adjustment screw thread of taper adjusting screw rod 1 is provided with (as shown in Figure 2) respectively with the metering-orifice body 2 that has air passageways 3.
During use, metering-orifice body 2 is installed in motor car engine with in the main oil system air jet of Carburetor or the idle system air jet (as shown in Figure 3), also metering-orifice body 2 can be installed in motorcycle engine with in the main oil system air jet of Carburetor or the idle system air jet (as shown in Figure 4).According to motor actual demand oil-gas ratio; suitably adjust the position of adjusting screw rod 1 in air passageways 3; change the sectional area of air passageways 3; reach the purpose of supplying with optimum air amount; thereby when guaranteeing that same model Carburetor is contained on the motor of different size respectively; can both guarantee that Carburetor offers the gasified fossil fuel of the best atomizing effect of motor, widens the application area of same specification Carburetor.
