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.
