In this paper Computational Fluid Dynamics (CFD) analysis has been carried out to study the flow characteristics and mixing performance of producer gas and air in the specially designed producer gas carburetor for 15 kw capacity engine. The model is made up of a mixer chamber that has the essential inlets i.e. three inlets for air and one inlet for fuel to generate stable stoichiometric mixture at near to ambient conditions using the induction of the engine as the driving pressure differential for the flow, Then based upon the results obtained from the above analysis a new prototype carburetor designes having two, four and five air inlets keeping inlet area ratio of air and fuel constant were designed. Further analysis was then performed on the prototype carburetors to study the effect on the air-fuel ratio. The results of the simulation shows that a four hole carburetor give better fuel distribution characteristics than the designed carburetor.
