预燃室湍流射流点火甲醇发动机稀薄燃烧和排放特性试验研究OA北大核心CSTPCD
Experimental Investigation on the Lean Combustion and Emission Characteristics of the Methanol Engine by Pre-Chamber Turbulent Jet Ignition
基于一台四冲程单缸发动机开展预燃室湍流射流点火(turbulent jet ignition,TJI)甲醇发动机燃烧特性、性能表现和排放特性的试验研究.结果表明,TJI燃烧模式燃烧速率较快,放热率(heat release rate,HRR)峰值明显较高,且具有更短的滞燃期和燃烧持续期.随着过量空气系数变大,缸内压力和放热率峰值变小,TJI和火花塞点火(spark ignition,SI)燃烧模式滞燃期和燃烧持续期均变长.此外,TJI燃烧模式可有…查看全部>>
The combustion characteristics,engine performances and emission characteristics of a pre-chamber turbulent jet ignition(TJI)methanol engine were investigated experimentally by a four-stroke single-cylinder engine.The results show that,TJI combustion mode has a higher burning rate,and the heat release rate(HRR)peak is higher than that of spark timing(SI)combustion mode.Meanwhile,the ignition delay and combustion duration of TJI combustion mode is significantl…查看全部>>
