The equivalent two-stroke method was used to establish the 1D simulation model of OPO2S diesel engine with GT-power. Taking the heights and the ratios of width to circumference from the intake and exhaust port as the test parameters, the orthogonal experiment was designed. Taking the average indicated pressure, feed ratio and scavenging efficiency as the evaluation indexes, Taguchi algorithm was used to analyze the signal-to-noise ratio of simulation results and the test parameters were optimized. The order of influence degree of each parameter on the ventilation effect of OP2S diesel engine was acquired and the optimal port structure was determined. The results showed that the optimal parameter combination was obtained and therefore the ventilation performance of OP2S diesel engine effectively improved by using Taguchi algorithm.
