“…Using hydrogenated vegetable oil and biodiesel, Pechout et al [43] reported different emissions including NO2 during the cold-start section of different driving cycles. There are also few more articles in this field reporting NO2 and the NO2/NOx ratio emissions during cold-start engine operation using alternative fuels [44][45][46]. However, after an extensive literature review, we could find no literature which investigates NO2 and the NO2/NOx ratio with alternative fuels at different stages of engine warm-up including coldstart and also phases outside the officially defined cold-start boundary (EU Directive 2012/46/EU) which cannot be considered as hot-start either.…”

The emissions from vehicles in real world driving are of current concern, as they are often higher than on legislated test cycles and this may explain why air quality in cities has not improved in proportion to the reduction in automotive emissions. This has led to the Real Driving Emissions (RDE) legislation in Europe. RDE involves journeys of about 90km with roughly equal proportion of urban, rural and motorway driving. However, air quality exceedances occur in cities with urban congested traffic driving as the main source of the emissions that deteriorate the air quality. Thus the emissions measured on RDE journeys may not be relevant to air quality in cities. A Temet FTIR and Horiba exhaust mass flow measurement system was used for the mass emissions measurements in a Euro 4 SI vehicle. A 5km urban journey on a very congested road was undertaken 29 times at various times so that different traffic congestion was encountered. Each journey was split into ten sections in order that the location and traffic conditions of the highest emissions could be determined. It was found that low speed stop-start traffic has much higher emissions than for freely moving traffic and most of the higher emissions on the longer 5km journeys occurred in relatively short sections of slow moving stop/start traffic. The journey used passed a roadside air quality monitor that exceeded the EU NO2 and PM standards on an annual basis and it was located by the most congested part of the route, where the traffic emissions are shown in this work to be at their highest.
