This course, which is based on our long standing CPD course on Diesel Particulate and NOx Emissions, was completely revised in 2016 to include real-world driving emissions and the development of European Real Drive Emissions (RDE) legislation and the reasons for modern SI and Diesel vehicles to have higher emissions in real world congested traffic than they do on legislated test cycles. This leads to worse air quality in cities. The technology of SI and Diesel engines for low CO2 is converging and SI engines have significant particulate emissions relative to modern diesels with particulate filters. This is leading to the requirement for Gasoline Particulate Filter for gasoline direct injection engines (GDI), but this is likely to be extended to PFI gasoline in the future as the use of rich mixtures in transient acceleration leads to the generation of soot.
The Real Drive Emissions additions to the course are based on the extensive experience in this area of BOSMAL and Prof. Gordon E. Andrews, both of whom have published on RDE for over 12 years and been researching in this area
for 20 years. This experience includes both SI and Diesel passenger car and truck RDE. Prof. David Kittelson also has considerable experience in on-road emissions measurements with vehicles measuring their own exhausts and for chase vehicles and his work has concentrated on particulate and particle size emissions. The issue of whether current EU proposals for RDE testing address the issue of poor air quality in cities will be discussed, as such RDE testing must include congested traffic and cold start if they are to be realistic. Currently the proposals do not address these issues.
The course covers the sources of emissions of CO, HC, NOx and PM in SI and diesel engines and on the design and
operation of catalytic and particulate emissions reduction systems for both vehicles. The latest technology for emissions reduction from SI and diesel engines is reviewed and the consequences for NOx, CO, HC and PM emissions of CO2 legislation that is making fuel consumption the primary driver in engine development at present. Engine calibration methodology that can reduce fuel consumption at the expense of NOx and PM engine out emissions is reviewed, which leads to RDE problems if the aftertreatment system for NOx and PM emissions cannot cope with the more transient demands of RDE in congested traffic with longer cold starts.
The 2018 course programme and leaflet will be available approximately 3 months prior to the course. However, you can view and download the 2017 course details for further information by clicking the course leaflet and course programme link.

Who should attend?
Who should attend?
The course is relevant to vehicle manufacturers, engine consultancies and emissions control R&D with an interest in RDE and engine and emissions control technology for Euro 6 and beyond as well as for technology for future CO2 emissions reduction. The course is also relevant to those who need to understand real world traffic emissions from an air quality viewpoint and to those involved in emissions regulation formulation and enforcement.
