Abstract(J) | エンジンの主なエネルギー損失である排熱損失と冷却損失を低減し,大幅な熱効率向上を実現すべく,本研究室では多重衝突パルス噴流圧縮原理を提案し実験を行ってきた.本研究では8本の吸気管から燃焼室に混合気を取り込んだ場合と,1本の吸気管のみから吸気した場合とで燃焼実験を行った.燃焼室壁に設置した圧力センサによって得られた結果から,ノッキングレベルについて検討し報告する. Translation |
Abstract(E) | We have proposed a new compressive-combustion principle of colliding pulsed supermulti-jets to improve thermal efficiency drastically by reducing cooling loss and exhaust heat loss. We developed a prototype gasoline engine with octagonal colliding pulsed supermulti-jets and double piston unit. In this research, we mainly did combustion experiments for the octagonal colliding jets injected from eight intake ports, while also for single intake port, which is performed by shutting off seven jets among eight, i.e., similar to conventional piston engine having an intake port and an intake poppet valve. The experimental results indicate the new compressive-combustion principle brings less knocking. |
