| Summary: | Air motion within the intake system is one of the important factors which govern the performance of an
engine. Hence the flow phenomenon inside the intake system should be understood. The whole intake system of 1.3L twin venturi carburetor engine from air induct until manifold is modelled by SolidWorks and 3-D simulation is presented by using COSMOS FloWorks. Flow field velocity varying to engine speed is observed and is compared with theoretical result for validation. CFD simulation is also done in the filtering which the flow in a section of an intake system is considered resisted by a porous media. Besides that, steady state simulations have been accomplished to obtain the flow behavior due to the pressure loss for variation operating condition of idle speed, wide open throttle and sudden acceleration in the intake system. At last, comparison between the flow behavior in the first runner and second runner are observed. Finally, according to the simulation result, some suggestions are recommended to improve the performance of intake system. |
