1997年4月17日～30日日本日产柴油机技术研究所所长林裕先生应邀来锡进行技术指导。今将有关改进供油系统、降低柴油机排放的内容整理成文,供同行们参考。 1 柴油机排放产生机理 柴油机排气中的氮氧化物(NO_x)是燃油在高温高压下燃烧生成的。温度对NO_x形成影响很大。燃烧温度超过2000℃时,NO_x急
April 17, 1997 to 30 Japan Nissan Institute of diesel engine technology director Lin Yu invited to Tin technical guidance. The contents of improving the fuel supply system and reducing the emission of diesel engines will now be organized and written for reference by their counterparts. 1 Diesel engine emissions mechanism Diesel engine exhaust nitrogen oxides (NO_x) is the fuel combustion under high temperature and pressure generated. The temperature has a great effect on NO_x formation. When the combustion temperature exceeds 2000 ℃, NO_x is urgent
