The objective of this work was to develop a new design of an intake manifold through a 1D simulation.
It is quite familiar that a duly designed intake manifold is essential for the optimal performance of an
internal combustion engine. Air flow inside the intake manifold is one of the important factors, which
governs the engine performance and emissions. Hence the flow phenomenon inside the intake manifold
should be fully optimized to produce more engine power with better combustion and further reduces the
emission.
In this paper, during the new engine development the pressure waves for the intake manifold is simulated
using 1D GT-POWER software, to study the internal air flow characteristic for the 4-cylinder gasoline
engine during transient conditions. Based on the 1D simulation results, the intake manifold design is
optimized. As a result of this analysis, intake manifold with 2.5% improvement in volumetric efficiency is
achieved.
