项目摘要

With the on-going roll-out of electric vehicles, tyres and their associated emissions are potentially becoming the biggest source of pollution from motor vehicles, but measuring them is hard. It is an important area as tyres have been identified as potentially the largest source of microplastics in the ocean, as a result of run-off into water courses. Emissions Analytics has been leading the development of real-world test methodologies, both for tyre wear rates, but also to profile the chemical composition and potential toxicological effects of the wear on humans and the wider environment. Initial work on potential regulation is underway at the United Nations.Tyre wear is more complex to measure than other emissions, including tailpipe, because tyres are part of an open system, where material abraded from tyre is 'sprayed' into the environment, where it mixes with other material - brake wear, road wear, resuspended dust and pollution from other sources. The challenge, therefore, is to be able to take a sample from on or near a vehicle and being able to estimate with good accuracy the tyre wear material contained in it, separately from the non-tyre components. Each of those pollution sources has a different chemical fingerprint, or contains unique tracers that can help separate them from each other. Without such separation, while we can measure the material lost from a tyre, we cannot fully understand in what form it is shed and where it goes.Emissions Analytics has an existing capability to measure the organic constituents of tyre wear using an in-house state-of-the art chemical analysis, using which it has developed a tyre fingerprinting database for the potentially harmful carbon-containing compounds in tyres. It has also developed a patent-pending system for physically sampling tyre wear material on a vehicle as it drives around in the real world. Therefore, many of the components required are in place to address the problem, but additional analytical expertise in both sampling optimisation and source apportionment data analysis is needed to achieve a high quality, market-ready offering.Therefore, by addressing this sampling and measurement challenge, there is the potential to unlock private sector value together with a public value in addressing current and pre-empting future environmental challenges. For Emissions Analytics, it would form an additional element to its growing suite of tyre analysis services.
随着电动汽车的不断推出,轮胎及其相关排放可能成为机动车最大的污染源,但很难对其进行测量。这是一个重要的领域,因为轮胎已被确定为海洋中微塑料的最大潜在来源,因为它会流入水道。Emissions Analytics一直在引领真实世界测试方法的开发,不仅用于轮胎磨损率,还用于分析化学成分以及磨损对人类和更广泛环境的潜在毒理学影响。联合国正在进行可能的监管的初步工作。轮胎磨损比其他排放(包括排气管)更难测量,因为轮胎是一个开放系统的一部分,从轮胎上磨损的材料被“喷洒”到环境中,在那里它与其他材料混合-制动磨损,道路磨损,再悬浮的灰尘和其他来源的污染。因此,挑战在于能够从车辆上或附近取样,并能够与非轮胎成分分开,以良好的精度估计其中所含的轮胎磨损材料。这些污染源中的每一个都有不同的化学指纹,或者包含独特的示踪剂,可以帮助将它们彼此分开。如果不进行这种分离,虽然我们可以测量轮胎损失的材料,但我们无法完全了解这些材料是以何种形式脱落的,以及它们去了哪里。Emissions Analytics拥有使用内部最先进的化学分析来测量轮胎磨损的有机成分的现有能力,并利用该分析开发了轮胎中潜在有害含碳化合物的轮胎指纹数据库。它还开发了一种正在申请专利的系统,用于在真实的世界中对车辆上的轮胎磨损材料进行物理采样。因此,解决这一问题所需的许多组成部分已经到位,但需要在采样优化和源解析数据分析方面的额外分析专业知识,以实现高质量、市场就绪的产品。因此,通过解决这一采样和测量挑战,有可能释放私营部门的价值以及公共价值,以应对当前和预防未来的环境挑战。对于Emissions Analytics来说,它将成为其不断增长的轮胎分析服务套件的一个额外元素。
