Abstract

The current research focuses on the impacts of pine oil injection and hydrogen induction separately with hemp oil methyl ester (HOME) in the single cylinder diesel engine in dual fuel-reactivity controlled compression ignition (DF-RCCI) combustion mode. The engine was tested under a DF-RCCI mode for the different energy shares of 10% pine oil with HOME (10P-HOME), 30% pine oil with HOME (30P-HOME), 3-lpm hydrogen with HOME (3-lpmH₂-HOME), and 6-lpm hydrogen with HOME (6-lpmH₂-HOME) separately at 345 °CA bTDC of low reactivity fuel (pine oil and hydrogen) and 23°C bTDC injection timing of high reactivity fuel (HOME). The results showed a higher Brake Thermal Efficiency (BTE) of 7.44%, 5.32%, 5.72%, and 2.46% for 6-lpmH₂-HOME, 3-lpmH₂-HOME, 30P-HOME, and 10P-HOME fuel shares, respectively, over the conventional diesel combustion (CDC) at full load. 30P-HOME, 3-lpmH₂-HOME, and 6-lpmH₂-HOME fuel combinations recorded 4.08% 4.42%, and 5.69% lower brake specific fuel consumption (BSFC), respectively, at full load. When comparing DF-RCCI combustion to CDC, an increase in the heat release rate (HRR) of 2.89%–26.50% and a rise in peak cylinder pressure of 0.77%–12.99% were observed. The 30P-HOME, 3-lpmH₂-HOME, and 6-lpmH₂-HOME emit less smoke in DF-RCCI combustion mode by 13.06%, 4.84%, and 7.26%, respectively at full load condition. When using 30P-HOME the exhaust gas temperature (EGT) decreased by 3.50% at full load condition. At part and full load conditions, the 30P-HOME fuel share reduced oxides of nitrogen (NO_X) emissions by 3.93% and 5.26%, respectively.

松油和大麻油甲酯氢气诱导对柴油机双燃料反应控制压燃燃烧的影响

目前的研究重点是在双燃料-反应控制压燃（DF-RCCI）燃烧模式下，在单缸柴油发动机中分别喷射松油和氢气诱导麻油甲酯（HOME）的影响。在低反应性燃料（松油和氢）的 345 °C bTDC 和高反应性燃料（HOME）的 23 °C bTDC 喷射时机下，分别对 10%松油加 HOME（10P-HOME）、30%松油加 HOME（30P-HOME）、3-lpm 氢加 HOME（3-lpmH2-HOME）和 6-lpm 氢加 HOME（6-lpmH2-HOME）的不同能量份额进行了 DF-RCCI 模式下的发动机测试。结果表明，在满负荷时，6-lpmH2-HOME、3-lpmH2-HOME、30P-HOME 和 10P-HOME 燃料份额的制动热效率（BTE）分别比传统柴油燃烧（CDC）高 7.44%、5.32%、5.72% 和 2.46%。满负荷时，30P-HOME、3-lpmH2-HOME 和 6-lpmH2-HOME 燃料组合的制动比油耗（BSFC）分别降低了 4.08% 4.42% 和 5.69%。在将 DF-RCCI 燃烧与 CDC 燃烧进行比较时，观察到热释放率（HRR）增加了 2.89%-26.50%，气缸压力峰值上升了 0.77%-12.99%。在 DF-RCCI 燃烧模式下，30P-HOME、3-lpmH2-HOME 和 6-lpmH2-HOME 在满负荷条件下排放的烟雾分别减少了 13.06%、4.84% 和 7.26%。使用 30P-HOME 时，满负荷条件下的废气温度（EGT）降低了 3.50%。在部分和全负荷条件下，30P-HOME 燃料份额分别减少了 3.93% 和 5.26% 的氮氧化物（NOX）排放量。
