Fuel Supply Characteristics in the Transition Region of Fixed-Venturi Type Carburetor

抄録

This paper reports computative and experimental investigation on the fuel supply characteristics in the transition region where the fuel supplied from main-system begins to join the fuel discharged from the idle-system in the fixed-venturi type carburetor. The investigation have revealed the effects of geometric parameters in both systems by introducing the relation between the carburetor air flow and fuel levels in a main well and an air bleed tube on the fuel supply characteristics in the transition region. The computative simulation developed in the report is available for predictings the fuel supply characteristics not only in the transition region but also the whole regions.
