The use of biodiesel in agriculture is increasing rapidly. Valtra has a long tradition of testing and using biodiesel in tractors. In Brazil alcohol distilled from sugarcane has been used to a large extent in Valtra tractors for a long time already. In Finland the use of biodiesel in Valtra tractors has been tested over the last couple of decades with good success. Sisu Diesel’s CR engines satisfy Tier III emissions regulations, also in terms of biodiesel. Valtra tractors can run on 100 % biodiesel (11/2007) if the biodiesel complies with EN 14214 or ASTM D 6751 standards.
Sisu Diesel’s engines do not need to be modified before using biodiesel. However, when biodiesel is used in any Sisu Diesel (or Valmet) engine, the engine oil, oil filter and fuel filter must be changed twice as often as required by the normal service interval. In addition, for Common Rail Engines, an additional pre-filter is required and this must be fitted between the fuel tank and the engine.
