Since 2011, the Euro 5b European standard limits the particle number (PN) emissions in addition to the particulate mass (PM) emissions. New thermal engine equipped vehicles also have to auto-diagnose their own particulate filter (Diesel particulate filter or gasoil particulate filter) using on-board diagnostic (OBD) sensors. Accumulative resistive soot sensors seem to be good candidates for PM measurements. The aim of this study is to bring more comprehension about soot microstructures construction in order to link the response of such a sensor to particle size and concentration. The sensor sensitivity to the particle size has been studied using successively an electrostatic and an aerodynamic classification, showing the same trend.
自 2011 年以来，欧洲 5b 号标准除了限制颗粒物质量 (PM) 排放外，还限制了颗粒数量 (PN) 的排放。装有新型热机的车辆还必须使用车载诊断 (OBD) 传感器自动诊断其自身的微粒过滤器（柴油微粒过滤器或汽油微粒过滤器）。累积式电阻式 soot 传感器似乎是 PM 测量的良好候选者。本研究的目的是更好地理解 soot 微观结构的构建，以便将这种传感器的响应与颗粒尺寸和浓度联系起来。通过静电和空气动力学分类，研究了传感器对颗粒尺寸的敏感性，结果表明存在相同的趋势。
