Computational analysis of air intake system for internal combustion engine in presence of acoustic resonator /
Volumetric efficiency is the breathing capacity of the engine during the suction stroke where piston is moving from top dead centre (TDC) to bottom dead centre (BDC). Volumetric efficiency is one of the important parameters which affect the performance of four-stroke engines. Any change in engine pa...

| 520 | |a Volumetric efficiency is the breathing capacity of the engine during the suction stroke where piston is moving from top dead centre (TDC) to bottom dead centre (BDC). Volumetric efficiency is one of the important parameters which affect the performance of four-stroke engines. Any change in engine parameters especially intake and exhaust system directly influence the volumetric efficiency of the engine. This study examines the effect of resonators on the volumetric efficiency over a wide range of engine speeds. Intake system with and without resonator are simulated using GT-POWER software. Intake systems with three configurations of resonators with various resonator volumes are represented in terms of volumetric efficiency. The three intake system configurations are in-series, side-branch and double resonator. The results obtained are compared with intake system without resonator. Intake system with resonator gives a significant improvement of volumetric efficiency at medium and high speed compared to intake system without resonator. However, the volumetric efficiency drops at low engine speed. Among these three configurations, the double resonator has the highest value of volumetric efficiency followed by side-branch and in-line resonators. The percentage increases are 20%, 17% and 14% respectively taken at maximum peak. The changes in resonator volume also give effect on the volumetric efficiency of the engine. Volumetric efficiency showed an increment when the volume of the resonator increased. Overall, simulations indicate that the presence of resonator in the intake system affects the volumetric efficiency of the engine especially for single cylinder engines. Volumetric efficiency worsens at low engine speed but has good increment at medium and high speed. However, the ability of resonator to improve the volumetric efficiency of multi-cylinder engines is insignificant in comparison with that for single cylinder engines. | ||
