| 摘要 |
The invention refers to a device for the homogenisation of fuel-air mixtures, used to equip the carburettor of internal combustion engines with spark ignition. According to the invention, the device is made up of an element (1) which has a flange (a) that enables the fuel-air mixture to be fixed inside a bore (b) located on the intake manifold (2). In order to increase the flow rate of the fuel-air mixture, the cylindrical element (1) is provided with a convergent-divergent nozzle (c). The ratio between the inner diameter and the outer diameter of the cylindrical element (1) is 0.7 d/D 1.2 , and the ratio between the height and the outer diameter is 0.08 h/D 0.3.
