ANALYSIS OF A CARBURETOR’S VENTURI UNDER DIFFERENT INCLINATIONS OF CHOKE VALVE AND THROTTLE VALVE

Abstract

Present research work is devoted to investigations in effect of inclinations of choke valve and throttle valve on the performance of venture section of a carburetor. For this purpose, a simulation approach is being adopted, under which a versions of a standard model of carburetor is designed and CFD analysis is done under different inclinations of choke and throttle openings. The results pointed out that the optimal opening angles for choke and throttle valve are 30 degree and 40 degrees, respectively.
