甲醇/柴油共置燃烧技术的尾气排放研究

摘要

Methanol fuel can be used to replace part of the diesel fuel to burn in the internal combustion engine,which can fully burn the fuel and reduce the harmful emissions,because the methanol contains only one carbon atom,sulfur-free,and high oxygen content.In this paper,the methanol/diesel co-combustion system operated in WP10 diesel engine,in which the exhaust emissions were reduced a lot,the smoke emissions reduced by 80％ compared with the original machine,and all the exhaust emissions meet GB 17691-2005 (Ⅳ).%甲醇只含一个碳原子,不含硫等且含氧量高,使用甲醇燃料替代部分柴油在内燃机燃烧后,可使燃烧充分并降低柴油机有害气体排放.本文采用甲醇和柴油共置燃烧方式在潍柴WP10高压共轨电控柴油机上运行,其中各尾气排放量较原机大量降低,烟度排放量降低80％,满足GB 17691-2005国Ⅳ排放标准要求.
