Analysis of Multicylinder Petrol Engine Intake Manifold Flow using CFD
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
Multicylinder engines are most widely used in high sector cars so as to get comfort. The power balancing of multicylinder engines are very high but the fuel efficiency is not in the expected range. This is due to the location of carburetor, length and diameter of intake manifold runners, geometry of pipe junction, design of manifold itself and etc. Now days there are advanced technologies like Multi Port Fuel Injection (MPFI) to overcome this problems but some attention to be given to the carburetor type engine. Design and operational variables of inlet system are decisive factor to determine engine performance. The engine overall performance can be obtained by proper design of the engine inlet system. The various aspects of the intake manifold design that affect the engine performance are to be analyzed and optimum parameters are found out using Design of Experiments (DOE). The parameters are modeled and computer flow model of intake manifold has been developed using Computation Fluid Dynamics (CFD) code. The parameters are analyzed and the optimum parameter has chosen using the design of experiments. Finally evaluate the optimum parameter result to the actual dimension results. Flow inside the intake manifold is assumed to be two-dimensional, unsteady, compressible and turbulent. Computer simulation results are presented in the form of velocity and pressure. The simulation results are comparing to the experimental data.
