From the article:
Currently there has been no Producer gas carburettors sold commercially. Some of the concepts evolved have not been optimized and are not standardized as well. In this view, development of an optimized carburettor for producer gas application addressing the low energy density of the delivered mixture is need of the time. Design of a carburettor for producer gas application with special reference for reduced loss of pressure is taken up to generate the optimal fuel–air mixture to meet different load conditions of the engine as well as for varying operating conditions of producer gas reactor. A specially designed producer gas carburettor is comprehensively analyzed for its mixing performance and response with a CFD modeling. The model is made up of a mixing chamber that has the essential orifices for air and fuel (producer gas) inlets to generate stable stoichiometric mixture nearer to ambient conditions. The CFD simulations are carried out followed with experimental studies under engine simulation conditions using pressure controlling system to validate the analysis. The results show a consistency in the experimental data and the modeling has provided a good insight into the flow details and has paved way in optimization of geometrical design to get a good mixing efficiency.
