Fuel (diesel engines)
Diesel fuel according to DIN EN 590. The cetane number of at least 49. Fuel PME (biodiesel) in accordance with DIN 51 606. Cars with diesel engine can operate on fuel RME (maslorastitelnom methyl ester).
Features fuel PME
Fuel PME obtained from a vegetable oil (preferably rapeseed oil) by a chemical process in which vegetable oil and methanol with a catalyst converted into fuel PME. PME fuel contains almost no sulfur. Therefore, during the combustion of the fuel is almost released sulfur dioxide. The combustion products contain less - Carbon monoxide
- Unburnt hydrocarbons,
- Solid particles (e.g. carbon black) than is obtained by the combustion of conventional diesel fuel. The content of harmful substances in the exhaust gas is less than the required legal standards. Fuel PME easily biodegradable. Fuel PME maintains sufficient fluidity to a temperature of about -15 ?� C. Fuel PME can be mixed in any proportion with conventional diesel fuel. There may be only insignificant deterioration tyagovodinamicheskih ing qualities of the car. Fuel PME may be somewhat higher.
Operation in winter conditions
When using summer diesel fuel at ambient temperatures below 0 ?� C may encounter disruptions to the engine as fuel due to loss of paraffin becomes viscous. Therefore, during the cold period of the year are used winter diesel fuel, which, depending on its grade ensures uninterrupted operation of the engine at a temperature of 15 ?� C or to -22 ?� C.
Heating of the fuel filter
The car is equipped with a heating of the fuel filter. Due to this fuel, intended to apply it at a temperature of -15 ?� C can be used at temperatures up to about -25 ?� C. If at temperatures below -25 ?� C fuel became so dense that the engine does not start, it is enough to give the car some time to stand in the heated room. For diesel fuel should not be admixed various additives, gasoline and other additives that enhance its fluidity.
