全球各地的公司和研究人员都使用 TSI 粒子仪器来收集有关发动机和车辆排放的关键数据，并用于监管法规审查工作。我们的产品可量化并分析轻型及重型发动机与车辆的颗粒物排放，适用于道路、非道路及固定应用场景。
在先进的内燃机和后处理系统的研发中，您会发现TSI产品的应用，例如柴油粒子过滤器(DPF)或汽油粒子过滤器（GPF）。我们的粒子计数器可精确量化气溶胶粒子的数量浓度。 TSI粒径谱仪用于测量尾气排放颗粒物的粒径分布。
我们的仪器可支持在排气管、定容采样器（CVS）或其他部分气流采样器处进行测量。
发动机排放研究与法规
欧盟、中国和印度的现行法规（如欧6/VI、国六、BSES VI）要求测量大于23 nm的固体（即非挥发性）粒子。研究表明，某些发动机技术如汽油直喷（GDI）会排放大量小于该粒径范围的粒子。 鉴于这些发现，下一阶段的法规如欧7标准可能会将这一限值降至10nm。为满足这些不断变化的标准，现已开发出先进工具，用于测量固体尾气粒子并提供时间分辨的粒径分布。 详细的粒子数据有助于优化发动机性能，确保符合严格的排放标准，并支持低排放车辆的研发。
非道路发动机排放测试
评估建筑行业机械、船舶发动机及其他非道路机械和设备在实际工况下的发动机排放已成为近年来的关注焦点。 TSI开发了一款符合瑞士法规941.242中的关于非道路移动机械(NRMM)要求的测试解决方案。在粒子浓度极高的工况下，例如未安装粒子过滤器的柴油发动机，新款设备已实现对固体颗粒物的全面监测，涵盖冷启动排放及生物质燃烧等污染源排放，其监测能力甚至可超越现行法规限值要求。
声誉良好的历史
30多年来，TSI始终引领粒子测量仪器的发展前沿，产品广泛应用于汽车发动机、非道路移动机械、航空及船舶引擎领域。这些解决方案为发动机研发及实际排放测试提供有力支持。 发动机开发商、后处理制造商以及汽车行业供应商利用这些数据来设计低排放车辆并优化后处理设备。 随着道路车辆排放标准的日益严格，飞机和船舶发动机等非道路污染源正成为重点管控对象，而TSI的检测设备为开发更清洁、更节能的技术提供了有力支持。
核准认证粒子数量（PN）测量
40多年来，TSI始终是制造业凝聚核粒子计数器领域的行业领导者，产品广泛应用于各类场景。 值得注意的是，TSI®凝聚核粒子计数器（CPC）作为联合国欧洲经济委员会（UN-ECE）主导的粒子测量计划（PMP）非正式工作组的开发过程中， TSI 凝聚核粒子计数器被视为标准参考仪器，对当前欧洲基于粒子数量的排放法规制定起到了关键作用。 如今，用于型式认证试验的仪器通常使用TSI 的发动机排放凝聚核粒子计数器（EECPC) 作为测量仪器完整解决方案的一部分，通过底盘测功机测量来认证车辆。

Time-Resolved Particle Size Distributions
Time-resolved particle size distributions (PSD) are essential for understanding the rapid changes in particle emissions from engines. Engine emissions testing requires tools that can measure particle concentrations and size variations in real-time, capturing transient events and providing a detailed profile of exhaust particulates. With high-resolution measurements, researchers gain insight into emission behaviors under different operational conditions, aiding the development of cleaner technologies and compliance with stringent emission standards. TSI’s particle sizing instruments, like the Engine Exhaust Particle Sizers (EEPS™), deliver sub-second response times, allowing researchers to track dynamic changes in PSD, critical for evaluating control technologies and understanding the downwind impacts of combustion processes.
Engine Particle Characterization
Physico-chemical characterization of particles emitted by internal combustion engines allows researchers to understand their structure, morphology, and chemical composition, which significantly influence their behavior and properties. This critical information can help engine manufacturers reduce particle emissions, assist climatologists in developing atmospheric chemistry models, inform public health researchers as to the human health effects of exposure to these particles, and aid aftertreatment manufacturers in designing particle filters to protect heavy equipment operators. The particles have to be sampled in an intelligent way to gather this information, however. MSP, a Division of TSI®, has been an industry leader for over 30 years in developing and manufacturing unique and innovative cascade impactors for size-resolved particle sampling, with applications spanning environmental sources, pharmaceutical aerosols, engine particle emissions, and more.
