The intake air manifold is a vital part of any internal combustion engine. The main purpose of the air intake manifold is to provide sufficient air to each cylinder and also equal distribution of air flow for each runner. The air needed to be distributed evenly within the runners, to achieve the maximum efficiency and performance of the engine. The present study is performed on the air intake manifold used over a 1.8-liter Dual Overhead Cam Engine (DOHC) in-Line16-valve 4-cylinder engine (2015 Model). The main objective of this study is to perform computational fluid dynamics (CFD) analysis using Ansys – Fluent package. The analysis is performed using steady-state and transient conditions. The simulations are performed by varying the air intake velocity, also the effect of each runner with references to the time (Transient). The mathematical calculation is performed to having different boundary conditions to enhancing the analysis. The results obtained for the outlet velocity using mathematical calculation 113m/sec and that of simulation is 79m/sec. This paper mainly focuses on the flow simulation study of the air-intake manifold using Ansys CFD Fluent for the four outlet runners with regards to the different inlet velocity. Furthermore, the study is incorporated by the mesh resolution method by using three different values such as (0, 4 and 7). This method can be adopted for any air-intake system and a comparative study can be performed. |
