Comparison of regulated emission factors of Euro 6 LDV in Nordic temperatures and cold start conditions: Diesel- and gasoline direct-injection
Open accessAbstract
Local air pollution in Norwegian wintertime is characterized by an increase in NO 2 concentrations, due to poor dispersion and increased vehicle emissions. The focus of this study is therefore the characterisation of exhaust vehicle emissions in cold ambient temperatures. Euro 6 Gasoline Direct Injection (GDI) cars and diesel cars were tested in the laboratory in cold temperatures, including with cold start of the engine. Results show high emissions of CO 2 , PM and NO x . For the first time, we report also elevated NO x values for GDI vehicles. Further measurements are required to investigate whether these results are the beginning of a new trend of high NO x emissions from GDIs, or if these results represent singular events, but it may indicate that further NO x traps or catalysts are required for these vehicles. Understanding the relationship of cold ambient temperatures and vehicle emissions is also particularly important for air quality dispersion modelling, which do not currently account for emission temperature dependence.

“Under extremely cold conditions, pollution emission rates from domestic heating and energy production are generally high, and traffic emissions at cold temperatures can release comparatively more pollutants than under higher temperatures due to inefficient combustion conditions (e.g., Brett et al., 2025;Weber et al., 2019;Zhu et al., 2022).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
