Summary:

The performance characteristics of naturally aspirated 4-stroke cycle engines are influenced by the through-flow or exchange of fresh charge for exhaust gas during the valve overlap period. During this gas exchange period the influence of unsteady wave effects in both inlet and exhaust systems are most important. Pressure-time histories were measured at various tract locations for four inlet/exhaust configurations to demonstrate the effects of wave action on performance.The good correlation shown between measured and predicted pressure-time histories suggested that the theoretical technique may be used in further design analyses with a high degree of confidence
