Abstract

We have previously proposed the concept of a new type of engine, based on a new compressive combustion principle based on the collision of supermulti-jets with pulse, while some combustion experiments qualitatively indicated a possibility of nearly-complete air-insulation and noiseless high compression. In this report, the compression level of the supermulti-jets colliding around the chamber center at the cold flow condition without combustion is quantitatively examined by three dimensional unsteady computations and also shock tube experiments. It is stressed that both computations and experiment results of pressure increases caused by the collision of the supermulti-jets agree at the chamber center fairly well, which indicate values much higher than tank pressures at upstream from the intake system of engine and also those of traditional pulse denotation engines. This important milestone data will lead from basic engine research to engine development stage.
