Diesel Temperature dependency of the fuel Biodiesel (FAME) Scania uses the term biodiesel according to the EN 14214 standard to refer to renewable diesel which is made from greases or oils and metha- nol. The biodiesel should conform to the require- ments of European standard EN 14214. For biodiesel in accordance with EN 14214 the ge- neric term FAME is frequently used. At temperatures lower than those specified for the fuel, paraffin wax may precipitate from the fuel and block filters, pipes and hoses. The en- gine can then lose power or stop. The fuel is adapted for use in the specific climate of each country.
If a vehicle or an engine is to be operated in a temperature zone with a tempera- ture lower than normal, first identify the temper- ature properties of that particular fuel. Scania XPI engines are approved for diesel ac- cording to the EN 590 standard. EN 590 contains up to 7% biodiesel in accordance with EN 14214. The properties of the fuel when cold can be im- proved by adopting one of the following meas- ures before the temperature drops: Use of fuel oil in stand-by generator sets Install an electric fuel heater if this particular fuel is not suitable for the expected tempera- ture and no fuel is available with the correct temperature properties.
Add 0.5-2% alcohol (isopropanol) to prevent any water in the fuel from freezing and form- ing plugs of ice. Drain fuel tanks and drain or renew fuel filters regularly. Long-term storage of diesel, where the diesel comes into contact with water, may lead to the growth of micro organisms (bacteria and fun- gus). To avoid this in fuel used in stand-by gen- erator sets, i.e. ESP engines, Scania permits the use of fuel oil according to DIN 51603-1 and ЦNORM C 1109. IMPORTANT! Use of fuel oil is only permitted for ESP engines and under the following conditions: Mixing kerosene or other paraffins with the fuel is prohibited. The injectors may be damaged.
The fuel must not be stored or used in temper- atures under -10°C (14°F). The engine must not be equipped with an SCR system. Mixing petrol with the fuel is prohibited. In the long term petrol can cause wear in the injectors and engine. Definition of ESP ESP is an output class for stand-by generator sets in accordance with ISO 8528, which states that stand-by generator sets may be used under vary- ing loads for a maximum of 200 hours/year. ESP engines are intended for use as stand-by power supplies in the efficient electrical net- works in Europe, North and South America, Australia, New Zealand, Japan and Taiwan.
