To ensure continuing environmental and health improvements, it is important constantly to reassess what pollutants from vehicles are growing in significance. Emissions Analytics’ presentation looks at several pollutant sources that may need to be considered, supported by data from its independent, real-world EQUA test programme.
• Post-Euro-6 emissions regulation in Europe should not become an unnecessary burden, but rather should focus on the emerging environment threats
• Beyond widening the measurement of particle number, what focus should be put on the composition of particles, and compounds carried on the surface of particles?
• Ammonia emissions from the tailpipe are a part of this, in so far as they lead to secondary particle formation of a particular chemical make-up
• Volatile organic compounds are of interest from a number of angles: vehicle interior air quality and the off-gassing from materials; tailpipe speciation of hydrocarbons including formaldehyde; and off-gassing from tyres
• Overall, a holistic view of pollutant emissions, carbon dioxide and fuel efficiency is needed
• Emissions Analytics runs a large independent test programme, covering hundreds of vehicles across three continents each year
• Data is analysed an available in a unique database that is accessed by a governments, industry and others
• Emissions Analytics’ database contains a large amount of test data covering passenger cars, light commercial, heavy commercial and off-road
• We will share test results and data with the SAE delegation
Sub-sessions cover emissions measuring techniques and testing regimes. This includes new analysis techniques and the novel application of existing techniques, the comparison of existing and proposed testing regimes with real world experience, including modelling.
Our founder, Nick Molden is on the agenda discussing ‘The increasing importance of particles, volatile organic compounds and ammonia in future air quality policy.’
