Istotnym celem europejskiej polityki transportowej, jak wynika z opublikowanej w marcu 2011 r. Białej księgi "Plan utworzenia jednolitego europejskiego obszaru transportu - dążenie do osiągnięcia konkurencyjnego i zasobooszczędnego systemu transportu", jest zapewnienie wzrostu sektora transportu i wspieranie mobilności przy jednoczesnym obniżeniu emisji związków toksycznych w tym sektorze o 60% (...). Uwzględniając cele europejskiej polityki transportowej, podjęte zostały liczne inicjatywy legislacyjne, które doprowadziły do przyjęcia pakietu klimatyczno-energetycznego. Zobowiązano się w nim m.in. do zwiększenia do 2020 r. udziału paliw z odnawialnych źródeł energii do poziomu 10%.

The results of comparative research of the organie components in the exhaust emissions of the CI engine fuelled with Diesel oil or rape seed methyl esters (RSME) were presented in this paper. The experimental works reported here was carriedout on the turbocharged, four cylinder, water cooled, CI engine, T 370 type (80 kW rated power at 2400 rpm, 400 Nm maximum torque at 1440 rpm, bore/stroke - 110/120 mm, displacement volume - 4560 cm3, compression ratio 17:1). The Signal equipment and AVL eeuipment were used for regulated exhaust emissions measurements and Hewlett Packard chromatograph type HP 5890 H for measurements of organic species emissions. The research was carried out under engine full load at maximum torque speed and at rated power speed. Using special equipment and normalized procedures the chromatographic test samples were collected. The 83 species were identified in HC emissions at these experiments but only the benzene, toluene and acetaldehyde were the components which were detected in substantial guantity. The research results show that the percentage emissions of individual components in total emissions of HC were weakly dependent on the used fuel. However in the case of RSME engine feed the HC emissions were lower than hose of the engine fuelled with Diesel oil and total emissions of their components were lower. Concluding, emissions from RSME combustion are less harmful than emissions of the engine fuelled with Diesel oil.

The article presents the results of the of the HC emissions composition for the compression ignition - diesel engine fuelled with rapeseed fuel (a mixture of methyl esters of fatty acids - RSME). The investigations were conducted on a turbocharged, four-cylinder compression-ignition engine type T370 (of 80 hW power at 2400 rpm engine speed and maximum torque of 400 Nm at 1440 rpm engine speed, with bore/stroke 110 mm /l20 mm, displacement volume 4560 cm3, compression ratio 17). For the exhaust toxicity investigations the eauipment of Signal and AVL companies was used, and for composition of nonregulated hydrocarbons emissions investigations the Hewlett Packard Company chromatograph type HP-5890II was used. The investigations were conducted under engine full load at maximum torque speed and for engine rotational speed of the rated power. Chromatographic test for emissions were collected using special equipment and special procedures. The article presents the results of chromatographic investigations focusedon: benzene, toluene and acetaldehyde. It was found that the percentage of emission of individual components in the total emissions of HC was independent of the fuel used. However, due to the fact that in the case of rape fuel, emission of unburned HC was smaller and smaller were the absolute amounts of emissions components. Thus, emissions from combustion of rape fuel are less harmful than emissions from the engine fuelled with diesel oil.
