装有陶瓷粒子收集器的柴油机排放物的致变物的研究

A Study on Mutagens in Exhaust Emissions from a Diesel Engine with Ceramic Particulate Trap

此文主要介绍了用陶瓷粒子收集器减少柴油机排放物中微粒、可溶性有机成份和氧硫化物等的排放量。确定了排放物中的微粒和可溶性有机成份的生物实验反应的增强不是由于采样过程中可能产生的矫作物的影响。可溶性有机成份的生物活性增强受到排放物中含有的硝基芳香族成份的影响。

A porous ceramic paraticlate trap was evaluated on a medium—dutydiesel engine.Tests were conducted at №.4 mode of EPA 13 mode heavyduty cycle to measure the total particulate,soluble organic fraction(SOF),sulfates and hydrocarbons emitted by the engine with and withoutthe trap.Thand hydrocarbons emitted by the engine with and without thetrap.The Ames biossay results showed that the mutageniciy/μg of SOF didnot change with sampling time and sampling process,but the effect ofnitroaromatic compounds in exhaust emissions on revertant emession ratesof SOF is significant.
