Abstract
The new European Commission Regulations for vehicle certification include a new
laboratory procedure for fuel consumption and require Real Driving Emissions
(RDE) to be gauged on-road with Portable Emissions Measurement Systems (PEMS).
The goal of this investigation is to underline some critical issues in the
development of RDE cycles with particular reference to the repeatability on-road
and the reproducibility on-track. More specifically, the study includes an
optimization of the route for RDE cycles to ensure robustness with respect to
traffic conditions, an analysis of emissions variability on-road in hot weather
and a discussion about the possibility to reproduce RDE cycles on-track. The
tests were performed with a start&stop Diesel Class3b vehicle that was
equipped with a PEMS instrumentation and tested over an optimized route in
summer in the southern Italy. The tests on the track were performed on the
testing facilities of the Nardò Technical Center. The emissions levels measured
in the on-road and on-track test were found to be strongly affected by ambient
conditions together with engine load and speed and cycle specification in terms
of speed and acceleration. This result underlines the necessity of improving the
corrections for NOx versus ambient temperature and humidity used in
the European Regulation and suggests the possibility to correlate the emissions
of NOx and CO2 to some parameters of RDE tests: vehicle
speed and acceleration, engine load and speed, ambient temperature and
humidity.
