| Abstract(J) | エンジンの異常燃焼であるノッキングに影響を与える因子として，燃焼室内の温度や混合気濃度の不均一性が挙げられる．2ストロークエンジンの点火位置を変えることで，排気ポートや掃気ポートの位置関係から，エンドガス部の温度や混合気濃度の分布が変わると考えられる．本研究では点火位置を変化させるほか，筒内にガス流動を与えることで，温度や混合気濃度の分布が自着火やノッキングにどのような影響を与えるかを調査した． Translation |
| Abstract(E) | Changing the ignition position of a two-stroke engine is expected to change the distribution of temperature and mixture concentration in the end-gas region due to the position of the exhaust port and scavenging port. In this study, in addition to changing the ignition position, the effects of temperature and mixture concentration distribution on auto- ignition and knocking were investigated by applying gas flow in the cylinder. As a result, it was found that the first auto- ignition tended to occur in the high-temperature region, and that knocking tended to be stronger when auto-ignition occurred between distant locations. |
