Study on Structural Stability and Thermal Analysis of Intake Manifold Valve through Numerical Analysis 2023-01-0989

Given that it improves engine efficiency and performance, the intake manifold is regarded as a critical component of the internal combustion engine (ICE). The right fuel-air mixture intake, which depends on the material geometry of the intake manifold, allows for the burning of the desired fuel-air combination.

The current study concentrates on the geometric modelling, structural analysis, and modal analysis of the intake manifold. By using Finite Element Analysis (FEA) software, static structural linear analysis and heat analysis were conducted to evaluate the structural safety. Following investigation, modal analysis revealed a minimum deformation of 56.34 mm at a frequency of 977.45 Hz and a maximum deformation of 104.22 mm at a higher frequency of 2518.1 Hz. According to study, the intake manifold structure is more vibration-resistant than cast iron when compared to aluminum and other materials. Cast iron and aluminum were used as the material for the thermal analysis. By looking at the thermal analysis results, it can be seen that the modified intake manifold model has a thermal flux rate of 0.71 and 0.68 and a heat flow rate of 0.21 and 0.17 on the surface medium.
