I.C.I.汽化器以泡沫薄层代替普通的雾化喉管,在样品中,采用一种滑阀式节流阀。在所有稳定工况范围内,该结构都能使空气—燃油比保持定值,且雾化性能好,因而可以省去加速泵和其他复杂补偿装置。所以,其固有成本远低于现有的汽化器。如图1所示,泡沫层直接装在滑阀上面,喷管机构夹在泡沫层中间。发动机工作时,空气 I.C.I. carburetor thin layer of foam instead of ordinary atomizing throat, in the sample, the use of a spool valve type throttle. In all stable operating conditions, this structure maintains a constant air / fuel ratio and provides good atomization performance, eliminating the need for acceleration pumps and other complex compensators. Therefore, its inherent cost is much lower than the existing carburetor. As shown in Figure 1, the foam layer is mounted directly on the slide valve and the nozzle mechanism is sandwiched between the foam layers. When the engine is working, air
