BIODEG is an acronym for “Influence of bio-components content in fuel on emission of diesel engines and engine oil deterioration”. The project will provide knowledge of the consequences of use of biodiesel in combination with fossil diesel in two areas: 1) emissions and 2) effect on motor oil. Western Norway Research Institute has the responsibility for the first area - emissions – through lifecycle assessments of the fuels' emission of climate gases and compounds with human health effects. Biodiesel produced from biological oils from three different sources will be investigated: 1) rape seed, 2) sunflower seed and 3) fish.
The project will last for 33 months and is financed through the EEA-financing mechanism (EEA Grants). Collaborative partners are the coordinator Oil and Gas Institute of Krakow (IniG) in Poland and Abgasprüfstelle Fachhochschule Biel (AFHB) in Switzerland.
The practice of blending the fuel with fossil diesel,c ommon in Europe, USA, and Canada, is done in order to comply with policy targets for increasing the share of transport fuels based on renewable energy sources. Results obtained from advanced modeling, designed to predict future consequences of the blending practice indicates that new toxic nanoparticles are being formed in the exhaust pipes of vehicles run on bio-blended diesel. This represents a likely mechanism for the increased exhaust mutagenicity of bioblended diesel observed in other studies.
