| Abstract(J) | 単気筒の予混合水素エンジンを用いてシリンダ―壁温を80℃から40℃まで変えた場合の高水蒸気分圧の水素燃焼ガスによる凝縮水の影響を調べた。この結果壁温が低下するほど、同じエンジンでのディーゼル燃焼と比べて20倍以上の水分割合にあることが分り、運転時間に応じて潤滑油中の水分量は増加することが確認された。 Translation |
| Abstract(E) | Using a single-cylinder premixed hydrogen engine, the effect of condensation of hydrogen combustion gas was investigated when the cylinder wall temperature was changed from 80°C to 40°C. The results showed that the lower the wall temperature, the more the water content was 20 times higher than in diesel combustion in the same engine, and it was confirmed that the amount of water in the lubricating oil increased depending on the operating time. |
