| All models, except 132 kW (AJQ) equipped with engines: Unleaded gasoline is not worse than AI-95 Use of unleaded gasoline not worse than AI-91 is allowed, at the same time engine capacity decreases. Models with engines of 132 kW (AJQ): Unleaded gasoline is not worse than AI-98. Use of unleaded gasoline not worse than AI-95 is allowed, at the same time engine capacity decreases. | |
| Diesel engines | |
| Diesel fuel | |
| on DIN EN1) 590 | Cetane number of not less than 49 |
| Biodiesel fuel | |
| on E DIN 51 606 | RME (methyl air of vegetable oil) |
| Almost does not contain sulfur. Therefore at combustion of RME are almost absent release of dioxide of sulfur (S02). Contains the fulfilled gases less: – carbon monoxide, – hydrocarbon, – soot. Insignificant power deceleration and increase in fuel consumption can take place. In cold season mainly fill diesel fuel. Application of RME is allowed at a temperature up to -10 °C. At a temperature less than -10 °C it is necessary to add diesel fuel to proportions 1: 1 to prevent RME fuel folding. In winter conditions When using summer option of diesel fuel at a temperature below 0 °C there can come interruptions in operation of the engine that is explained by a fuel gusteniye as a result of release of paraffin. Therefore apply "winter" diesel fuel. Depending on brand winter fuel provides uninterrupted operation at temperatures from -15 °C to -22 °C. Do not add gasoline to diesel fuel, etc. a flux oil. At poor quality of fuel removal of water from a settler of the fuel filter perhaps will be required to be made more often than it is provided by the schedule THAT. For removal of water turn off a hand a carving stopper in the lower part of the filter. The water congestion in the filter can lead to violations of operation of the engine. | |
