Description:The invention is illustrated with the help of the accompanying drawing figure 1 to 4. With reference to figure 1,2,3 and 4 the present invention illustrates that the front view, side view, top view and isometric view of the new manifold model – II. According to another embodiment of the present invention, as shown in figure 6 is the new manifold model -I. The design methodology incorporates new manifold models and existing manifold are designed and analyzed through FLUENT tool. The new manifold model - II has performed well, while comparing with other new manifold model and existing model. Once the models are designed using CAD software, they are imported into the ANSYS Fluent software for further analysis. The geometric design models are presented. The existing manifold model demonstrates four inlet pipes bending and merging into a single outlet pipe, facilitating efficient gas exhaust. The new manifold models (I, II) showcase variations in the design, such as a single horizontal pipe, a small horizontal pipe with a central exit resembling a nozzle, and inclined pipes merging into a horizontal exhaust pipe. Engine specifications for the Maruti Suzuki Wagon-R, a 4-stroke 4-cylinder CI engine. These specifications include details such as displacement, calorific value, bore and stroke dimensions, maximum power, maximum torque, and compression ratio.

, C , Claims:1. A manifold model - II for effective fuel flow in multi-cylinder diesel engine comprising of :
An inlet pipes (1,2,3,4) , a bend and a pipe towards exhaust. Where in the four inlet pipes are bends and merged to small horizontal pipe and center exist of the manifold like nozzle.
2. The method analysis of the design is to improve the performance and efficiency of the engine performance of manifold model-II which gives better result while comparing with other new manifold model.
