The complete process chain – from the production and the quality determination and standardisation of biofuels to the performance and emission properties of engines using biofuels – has been subject to the research of the Technology and Support Centre for more than 25 years.Established and novel biofuels are analysed, developed and ecologically assessed in the laboratory. At the tractor test stand, the performance, fuel consumption and exhaust emissions of engines suitable for running on vegetable oil are determined. Accompanying field tests give indications of their practical suitability. Finally, the use of vegetable oils as lubricants or component of biodegradable covering materials is tested.
Despite the growing interest in real operating emissions measurement and analysis of modern diesel and rapeseed oil powered tractors have been little studied. Here under real operating and ambient conditions, the emissions vary compared to the measurements on the test bench. Using a portable emissions measurement system (PEMS), TFZ has measured the emissions of a Fendt Vario 724 S4 with a Euro IV engine running on rapeseed oil fuel in accordance with DIN 51605 during ploughing in the field and on the tractor test stand.
Scientists in the subject group "Liquid Biofuels, Biolubricants and Process Materials" of the Technology and Support Centre have published a paper in the renowned journal "Biomass & Bioenergy". In this peer-reviewed journal research results in regard to production and usage of renewable resources are being published to an international audience. The article covers fundamental research, conducted at the Technology and Support Centre, that furthers the understanding of the use of vegetable oils as fuel for combustion engines.
Scientists of the subject group “Liquid Biofuels, Biolubricants and Process Materials" of the Technology and Support Centre have published a new paper about the “Emission behaviour of vegetable oil fuel compatible tractors fuelled with different pure vegetable oils” in the renowned journal FUEL. The scientific article was positively evaluated in the peer-review-process by international experts. Since the last 80 years FUEL is one of the leading journals where new fundamental research work in fuel sciences is published and discussed. In the research article new results concerning the influence of the molecular structure of different vegetable oils on the emission behaviour of vegetable oil compatible tractors are presented.
