为了节约油料,我们对幸福250摩托车汽化器主量孔进行了改革。现将改革后的麻花状双眼主量孔的结构特点和作用介绍如下。一、麻花状双眼主量孔的结构麻花状双眼主量孔的形成十分简单。取φ0.5毫米的铜线或铝线一截(长约35毫米左右),用钢丝钳铰成麻花形状后,旋入250的汽为了节约油料,我们对幸福250摩托车汽化器主量孔进行了改革。现将改革后的麻花状双眼主量孔的结构特点和作用介绍如下。一、麻花状双眼主量孔的结构麻花状双眼主量孔的形成十分简单。取φ0.5毫米的铜线或铝线一截(长约35毫米左右),用钢丝钳铰成麻花形状后,旋入250的汽化器主量孔中,上端以露出孔端面2～4毫米为宜。塞进主量孔内铜线的两个端头,分别卡进主量孔的铰刀槽中,然后用焊锡将它焊牢,(如图所示)。此时,主量孔就由一般单孔变成麻花状孔了。二、麻花状双眼主量孔的节油原理由于双眼主量孔比原来的主量孔截面积缩小约三分之二,其单位时间流量当然也相应地减少,因麻花条线在量孔中起螺旋的作用,它使气流形成涡流,通过主喷油咀和喷油针的作用,混合油中的颗粒得到粉碎,变成一种紊乱的混合气流,这样便提高了燃油的雾化程度,使燃料能充分地进行燃烧,从而达到了节油目的。三、使用效果和特点目前我局已有四辆摩托车采用了此种装置,取得了一定效果,现将其改革前后的车辆耗油情况对照如下:10064车采用标准主量耗油每百公里3.2公斤左右,采用麻花状主量孔后,在78年第3季度每百公里耗油2.0公斤左右,每百公里耗油量下降37.8%。78年第四季度每百公里耗油1.9公斤。百公里耗油量下降40.6%。四季度未换曲轴,未换缸,79年第一季度每百公里耗油1.59公斤,百公里耗油量下降50%左右。10066车采用标准主量孔、在新缸、新曲轴的情况下,百公里耗油4.5公斤左右,在没有对车辆换任何零部件情况下,采用麻花状双眼主量孔,79年第一季度百公里耗油2.1公斤左右,百公里耗油量降低2.4公斤。8845车在78年9月进局后就采用麻花状主量孔,到目前为止,耗油一直保持在百公里2.3公斤左右,比市局规定百公里耗油3.3公斤下降了1公斤。10068车采用标准主量孔,百公里耗油3公斤左右,采用麻花状双眼主量孔,79年2—3月均保持百公里耗油2.5公斤左右,百公里耗油量下降0.5公斤。此外,我们对10068及8845两车还进行了鉴定,发现其磨损情况和爬坡性能均符合出厂技术要求。车辆最高时速虽低于设计要求,但满足时速60公里的规定。实际上摩托车最经济的行驶速度为30～40公里/小时,适合农村投递的特点。麻花状双眼主量孔结构简单,工作可靠,不需要增加额外支出,也不用改动原汽化器的结构。由于使混合油燃烧充分,废气少,减少了气缸的积炭,也减少了对环境的污染。
In order to save fuel, we have carried out the reform on the main hole of blessed 250 motorcycle carburetor. Now the structure of the main features of the twist and the role of the main hole after the twist is described below. First, the twist of the main hole in the structure of the eyes Twist-shaped eyes of the main hole formation is very simple. Take φ0.5 mm copper or aluminum wire length (about 35 millimeters), with steel wire clamp articulated twist shape, into the 250 steam in order to save fuel, we happy 250 motorcycle carburetor main hole Reform. Now the structure of the main features of the twist and the role of the main hole after the twist is described below. First, the twist of the main hole in the structure of the eyes Twist-shaped eyes of the main hole formation is very simple. Take φ0.5 mm copper or aluminum wire length (about 35 millimeters), with steel wire clamp articulated twist shape, screw into the main volume of the vial 250, the upper end to expose the hole end 2-4 mm should. Insert the two ends of the copper wire in the main hole into the reamer slot of the main hole, and then solder it with solder (as shown). At this point, the main hole from the general hole into a twist hole. Second, the twist of the eyes of the main hole of the oil-saving principle As the main hole eyes binocular than the original main hole cross-sectional area of about two-thirds, of course, the corresponding reduction in the flow of time per unit, as a result of cannabis line in the amount of holes From the role of the spiral, which makes the air flow vortex, through the main nozzle and the injection needle role, the mixed oil particles are crushed, into a turbulent mixed gas flow, which will increase the degree of atomization of the fuel, So that fuel can be fully burned, so as to achieve the purpose of fuel-efficient. Third, the use of results and features At present I have four motorcycle Bureau has adopted such a device, and achieved some results, and now its vehicle fuel before and after the reform of the control are as follows: 10064 vehicles using the main standard fuel consumption per hundred kilometers 3.2 kilograms or so, the use of twist-shaped hole after the main hole in the third quarter of 78 per 100 kilometers fuel consumption of about 2.0 kg, 100 km fuel consumption decreased by 37.8%. In the fourth quarter of 1978, it consumed 1.9 kilograms of fuel per 100 kilometers. 100 kilometers fuel consumption decreased 40.6%. The fourth quarter did not change the crankshaft, did not change cylinder, the first quarter of 79 fuel consumption per hundred kilometers 1.59 kilograms, 100 kilometers fuel consumption decreased by about 50%. 10066 cars using the standard main hole, in the case of a new cylinder, the new crankshaft, fuel consumption per kilometer 4.5 kilograms, in the absence of any parts for the case of vehicles, the use of twist eyes main hole, the first quarter of 79 About 100 kilos of fuel per kilometer 2.1 kilograms, reducing fuel consumption per kilometer 2.4 kilograms. 8845 car in September 78 after entering the use of twist-shaped main hole, so far, fuel consumption has been maintained at about 2.3 kilograms per kilometer, than the municipal bureau prescribed fuel consumption of 3.3 kilograms per kilometer decreased by 1 kilogram. 10068 cars using the standard main hole, 100 km fuel consumption of about 3 kg, the use of twist-hole eyes of the main hole, 79 from February to March were 100 km fuel consumption of about 2.5 kg, 100 km fuel consumption decreased by 0.5 kg. In addition, we have 10066 and 8845 two cars were also identified and found that the wear and climbing performance are in line with the factory technical requirements. Although the maximum speed of vehicles below the design requirements, but to meet the provisions of 60 kilometers per hour. In fact, the most economical motorcycle speed of 30 to 40 km / h, suitable for rural delivery characteristics. The main hole of the twist-like eyes is simple in structure, reliable in work, does not need to increase additional expenditure, and does not need to change the structure of the original vaporizer. Due to the combustion of mixed oil, less exhaust, reducing the cylinder coke, but also reduce the pollution of the environment.
