Abstract

Three types of experiments of shock-tube, computation, and theoretical thought indicate a high potential of the new compression principle, which was proposed by first-author's patents and previous reports of us. The engine based on the principle essentially differs from the traditional four types of engines with piston, turbofan, ran-scram, and pulse-detonation, because the new compression principle is based on supermulti-jets colliding with pulsation. This engine makes it possible that higher compression ratios result in lower noise, lower emissions, and higher thermal efficiency. A way to generate pulsation is a new rotary plate valve, which is relatively silent. Shock tube experiments and numerical simulations on super-computers show a possibility of stable and high compression. This compression principle with supermulti-jets colliding can be used for three purposes of automobiles, aircrafts, and electric power plants. To say more on the possibility for near future automobiles, this compression principle is also effective for preventing the knocking phenomenon as the critical problem for small turbo-charged engines and also for realizing higher-power Atkinson cycle, extremely lean burning in direct injection engines, and silent auto-ignition engines of gasoline.
