Abstract:
Rapeseed oil fuelled tractors gain more and more importance in Germany. Since 2008 series produced vegetable oil compatible tractors are on the market and have a technical release for rapeseed oil due to DIN V 51605. However, the emission characteristics of those new exhaust gas stage IIIA tractors are widely unknown. Objects of investigation were two commercially available Fendt 820 Variogreentec tractors equipped with a two-tank-system with fuel-management. As fuels diesel, rapeseed oil and for one tractor sunflower oil has been used. Emission testing was done for all possible operation modes the driver can choose. The carbon monoxide (CO), hydrocarbon (HC) and particle mass (PM) emissions were lower with rapeseed oil than with diesel fuel, whereas the nitrogen oxides (NOX) emissions were higher. The lowest CO and PM emissions were reached, when the fuel-management system was enabled and in operation mode “AUTO”. Sunflower oil showed the same emission behaviour like rapeseed oil and from this point of view seems promising for being used as a fuel in vegetable oil compatible engines. Further research on the long-time behaviour of sunflower oil in tractors must be done and a fuel quality standard has to be set up like for rapeseed oil.
