- Summary:
- The use of alternative fuels and among them the biofuels of 1stgeneration - fatty acid methyl esters FAME's and pure plantsoils - for propulsion of IC engines is an important objective inseveral countries in order to save the fossil fuels and to limitthe CO₂ production.The properties of bio-fuels and bio-blend-fuels can vary andthis has an impact on the operation and emissions of diesel enginesand on the modern exhaust aftertreatment systems.The present paper represents the most important results obtainedwith RME at AFHB, EMPA and EC-JRC. Most of the activities wereperformed in the network project BioExDi (Biofuels, Exhaust SystemsDiesel) in collaboration between industry and researchinstitutes.Following most important statements can be given about thetreated subjects: - emissions (engine-out) are influenced by RME inthe sense less CO, HC and PM, more NOx and more SOF, -there are positive influences of RME on the functionality of DOCand DPF due to higher reactivity of RME, no influence on SCR, - thelong term functionality of exhaust aftertreatment systems with RMEcan be influenced by the potential higher availability of elements,like Ca, Mg, Zn, P, S, K, - regarding particle mass PM: without DPFthere are slight tendencies of lowering TEQ at low load with RMEand increasing TEQ at high load of the engine; with DPF there is astrong reduction of all toxic substances and there are no effectsof RME on PAH and TEQ.Some practical recommendations for the users of biofuels of the1st generation are given at the end of the paper. Generally thereis a necessity of higher costs and efforts for more frequentservice and maintenance and for the quality controls of fuel andfuel supply chain
