Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly.
Details options for and benefits of leapfrogging the Euro 5/V LDV/HDV vehicle emissions standards, and instead progressing directly from Euro 4/V to Euro 6/VI.
HDVs conforming to Euro IV and V standards frequently show poor real-world NOx emissions performance. Evidence indicates that new certification protocols in Euro VI resolve this problem, and Euro VI-compliant HDV NOx emissions meet expectations.
Documents the discrepancy between type-approval and real-world NOx emissions from new diesel passenger cars. On average, on-road NOx emissions from the vehicles tested for this analysis were about seven times higher than the limits set by the Euro 6 standard.
Results of a project by the Center for Alternative Fuels, Engines and Emissions at West Virginia University to conduct in-use testing of three vehicles, using a portable emissions measurement system, over a variety of test routes.
Beijing's new local standards to prevent excess NOx emissions from HDVs operating at low-speed in urban conditions make the city the first region in the world to address this deficiency in the Euro IV and V standards.
