本文將單缸直噴式柴油引擎與CO2吸收系統結合成密閉式循環柴油引擎(CCDE),並加裝乾、濕式防爆設備,於引擎進氣岐管導入ECU自動噴氫系統。引擎實驗操作參數將氧氣濃度固定於23%,ECU噴射角度為10°ATDC,採用三種KOH水溶液重量百分比濃度(CO2吸收藥劑)10%、15%、20%,四種氫氣預混合比0%、5%、10%、20%,在不同引擎之轉速和負載進行交叉實驗。量測引擎之排氣污染、經CO2吸收系統後之引擎進氣組成與缸內壓力,探討氫氣和KOH濃度對於CCDE系統燃燒特性之影響。
使用KIVA3V-RELEASE2為程式主體,藉由加入程式的詳細化學反應進行數值運算,分析不同氫輔助燃料對柴油引擎的影響。將數值模擬與實驗結果相互比較,證實模擬之可靠性,進而探討氣缸內之溫度場變化和汙染物之生成。
模擬與實驗結果皆顯示於柴油引擎添加輔助燃料氫氣,可增加預混合燃燒期之熱釋放率,進而有效降低CO2、CO和Smoke等排氣污染,增加KOH藥劑之使用壽命。然而,較高的峰值壓力與溫度會促使有害之NOX生成。

This thesis combines a single DI diesel engine with CO2 absorption system and installs the hydrogen injected automatically system, anti-explosion-burning system to form a closed cycle diesel engine. Operating parameters of the oxygen concentration are fixed at 23%, ECU injection at 10ATDC, KOH weight percentage concentration of 10%, 15%, and 20% (CO2 absorbent), and hydrogen pre-mixing ratio of 0%, 5%, 10%, and 20%. Engine exhaust pollution, gas content which before and after CO2 absorption system, cylinder pressure are measured to investigate the combustion characteristics of hydrogen and the concentration of KOH for the CCDE system.
The numerical simulation by KIVA3V is used as the main of the program modifying some sub-models with additional detailed chemical reaction, and the results between the simulation and the experiment will be identified. Then the temperature fields within the cylinder and pollutant generation are realized.
The simulation and experimental results show that a diesel engine is better with premixed hydrogen than without premixed hydrogen in decreasing exhaust emissions, and the result is conspicuous for the reduction of carbon-monoxide, carbon-dioxide and soot emission, so as to increase the life of CCDE system. However, a higher peak pressure and temperature will lead to NOX generation.
