Abstract

This study aimed to determine the effect of porting diameter variations on the performance of a Honda Tiger 200 cc engine using an intake manifold with a dimple pattern. An experimental method was employed using four manifold configurations: a standard manifold and modified manifolds with diameters of 26, 27, and 28 mm. Engine performance was tested using a dynamometer at 5500, 6500, 7500, 8500, and 9500 rpm. The observed parameters were power, torque, and specific fuel consumption (SFC). Power and torque data were analyzed using one-way ANOVA at a 5% significance level. The results showed that the 26 mm modified manifold provided the best overall performance, producing average power of 25.314 hp, average torque of 24.850 N·m, and SFC of 133.7 g/kWh. In comparison, the standard manifold produced 24.77 hp, 24.31 N·m, and 150.3 g/kWh, respectively. ANOVA indicated significant effects of porting diameter on torque (F = 4.78, p = 0.015) and power (F = 7.72, p = 0.002). CFD simulation supported these findings, showing maximum air-flow velocity of 27,348.96 cm/s in the 26 mm manifold. Thus, the 26 mm manifold was optimal.
