低活性燃料和直喷时刻对低负荷RCCI发动机着火燃烧特性影响的可视化试验研究
A Visual Experimental Study on the Impact of Low Reactivity Fuel and Direct Injection Timing on Combustion Characteristics of Low Load RCCI Engines
本研究的目标是探索在低负荷条件下RCCI(Reactivity Controlled Compression Ignition)燃烧模式所面临的挑战,即由于燃烧室中的稀薄燃料混合物导致的不充分燃烧甚至失火问题。为了解决这个问题,采用光学诊断和后处理技术,研究了在这低负荷下低反应性燃料和直接喷射时刻对双燃料发动机燃烧和火焰特性的影响。测试了三种不同的低反应性燃料和五种不同的直喷时刻,同时使用加氢化催化生物柴油(HCB)作为高反应性燃料。研究结果显示…查看全部>>
The objective of this study is to explore the challenges associated with the RCCI(Reactivity Controlled Compression Ignition)concept under low loads,where there may be insufficient combustion or misfires caused by a lean fuel mixture in the combustion chamber.To address this issue,optical diagnostics and post-processing techniques are utilized to investigate the effects of low-reactivity fuel and direct injection timing on combustion and flame characteristic…查看全部>>
