Tractors fueled with climate protection
TFZ certifies biofuel long-term practicality
Straubing, Germany, 21.02.2019.
"Recommendable!" Is how the scientists of the Technology and Support Center (TFZ) could describe their conclusion from analyzing modern tractors for functionality, efficiency and environmental impact in a long-term project. The special feature: The tractors were fueled with rapeseed oil fuel. In the research report that has just been published, the results are extremely positive: the biofuel is convincing in terms of both practicability and climate protection. Conclusion: Farmers can rely on the new technology.
The scientific results are based on 60,000 operating hours of 20 tractors fueled with standardized rapeseed oil fuel (DIN 51605). Engine performance, fuel consumption and exhaust emissions differed little compared to measurements from diesel-powered tractors. With regard to exhaust emissions, measurements on the tractor test bench and with portable emissions measurement technology (PEMS) in the field prove that the latest standards are met in rapeseed oil operation and the exhaust aftertreatment systems work reliably.
Dr. Edgar Remmele, area manager at the TFZ, points out the benefits for climate protection: "The drive of modern tractors with regionally produced rapeseed oil fuel causes about 90 percent less greenhouse gas emissions than diesel." Wherever electromobility reaches its limits, biofuels should be preferred be used. According to Remmele, this mainly includes machines in agriculture and forestry.
The project was funded by the Bavarian State Ministry for Economic Affairs, Regional Development and Energy. The research report is available as a free download at www.tfz.bayern.de
