2、研究怎样降低燃用重油的船舶柴油机的排放，越来越受关注。本文分析了船用柴油机燃用重油对排放的影 响，并且深入探讨了有害物质的形成机理。对国内外的减排方法进行分析，取其优点避其负面影响，最后提出了一 套有效的方案进行减排：海水水洗排气与排气再循环结合。这一方案能有效的减少 NOX、SOX、COX、PM 的排放。 关键词关键词：燃用重油；船用柴油机；排放；减排. 燃用重油对船舶柴油机排放的影响及对策 2 Effect and Countermeasures of Burning Heavy Fuel Oil on Emissions of Marine Diesel Engine Abstract
3、Abstract: Since twenty-first Century, the number of Chinas shipbuilding growing, Diesel Engine Fueled with heavy impact on the environment more and more, In order to protect our ecological environment, to study how to reduce the ship diesel engine fueled with heavy oil discharge, more and more atten
