Summary:The internal combustion engine has an intake system that preparing sufficient charges for the engine cylinder. This study is focused on the effect of different intake geometry on the intake pressure and brake mean effective pressure to correlate volumetric efficiency and brake power performance. Five types of intake geometry are simulated by a one-dimensional computational tool. Through the simulations, it can be found the maximum volumetric efficiency predicted by taper design at 1.15 bar of intake pressure and 12.50 bar of brake mean effective pressure when volumetric efficiency reached to 115% and brake power of 19.5 kW. The baseline intake and bellmouth intake showing intake pressure at 0.91 bar and 0.94 bar except for both single bend intake and s-bend intake indicated 0.92 bar intake pressure and 9.35 bar of brake mean effective pressure. The measurement of intake pressure and brake mean effective pressure over various intake geometry displayed a significant influence on the volumetric efficiency and brake power trend.
