DaimlerChrysler Off-Highway engines: Various engine series capable of running on biodiesel

• Engines released for operation with FAME, PME and RME
• No engine modification required

By running its machinery on biodiesel fuels, agriculture is able to use a kind of energy the raw material for which it provides itself. Considerably reduced soot emissions and an almost completely closed CO2 circuit during combustion are positive features of this kind of fuel which is also sulfur-free. There are now three abbreviations for biodiesel fuels in general use: FAME (fatty acid methyl ester) is the generic term used in EU standardization. PME (vegetable oil methyl ester) is a term previously used in the German language area. Finally, RME (rape methyl ester) designates biodiesel made from oilseed rape.

Following comprehensive test runs, the new Series 500 and 900 engines exhibited at Agritechnica, as well as DaimlerChrysler Off-Highway’s Series 460 engine have now been released for operation with DIN-compliant FAME, RME and PME biodiesel fuels.

No engine modification required

The Series 460 engine as well as the Series 500 and 900 engines can be operated with FAME fuels without modification, provided the fuel complies with DIN EN 14214. Running the engines on inferior-quality fuel may lead to damage and malfunctions. FAME biodiesel and diesel fuel can be used alternatively. The resulting mixtures of FAME and normal diesel fuel in the fuel tank do not represent any risk to engine operation.
