Modelling and Analysis of Spark Ignition Carburettor

Modern passenger vehicles with gasoline engines are provided with different compensating devices for fuel air mixture supply. Even there is a high fuel consumption because of many factors. One of the important factors that affects the fuel consumption is carburettor. The venturi of the carburettor is important that provides a necessary pressure drop in the carburettor device. For a better economy and uniform air fuel supply there is a need to design the carburettor with an effective analytical tool or software. In this work three parameters namely, pressure drop and fuel discharge nozzle angle and the throttle angle will be analysed using the computational fluid dynamics. For this analysis two soft wares are used namely CATIA and ANSYS. Whereas CATIA for designing of carburettor and ANSYS for analysis of the carburettor. The results obtained from the soft wares will be analysed for optimum design of a carburettor and also find out the exact pressure at various throttle angles and choke valve for a proper homogenous air fuel mixture.
