Design and Optimization of Inlet Manifold Nozzle for Single Cylinder C.I. Engine as per ISO: 9300

Abstract

The major aim of that paper to design the inlet manifold nozzle of single-cylinder C.I. engine for improving performance parameters like volumetric efficiency, exit velocity, pressure drop. In self-propelled vehicles or machines, the main function of the inlet manifold is to provide greater air for complete combustion inside the cylinder. Engine volumetric efficiency depends upon the mass flow rate of air for that select best turbulence model for the ISO: 9300 standard nozzles. As per standards have been adopted design consideration, four design variables are nozzle inlet diameter (D_i), inlet curvature radius (R), diffuser half-angle (θ) and length (L) with four levels of each variable. These four variables and four levels of each variable, we have a need to perform 256 experiment models, but we Design matrix by the help of the Taguchi method. Taguchi method is a procedure optimization method that is based on various levels of planning, conducting and evaluating results of matrix experiments to determine the best levels of control variables. Design of experiments (DOE) method widely accepted to define the relationship between control variables of the process and the output of that process. Hence L16 experiment matrix performs using DOE (Design of Experiments) in statistical tool Minitab software. Ansys CFD analysis for critical flow Venturi Nozzles and dimensions of nozzles optimize.
