Abstract
In a two-stroke-cycle gasoline engine, the scavenging flow plays a very important role in the combustion performance. The scavenging flow discharges the burned gas from the cylinder and draws the mixture of fresh air and gasoline into it. However, the flow pattern in the loop-flow scavenging system of this type of engine is very complicated and the measurement of the gas velocity and the gas concentration is difficult. Thus, there is little information on the flow characteristics in the cylinder. The authors have developed a simulation method for the uniflow scavenging two-stroke-cycle diesel engine. In this report, the authors outline the development of this method, applying it to the loop-flow scavenging two-stroke-cycle gasoline engine. The characteristics of the gas flow and the gas concentration in this engine are made clear by the simulation method.
