Test of plant oil as fuel and lubrication oil in an Indien type engine (Fieldmarshal) - Summary, (pdf-file 21 kb) |
The concept of using plant oil as fuel is not new. Already Rudolf Diesel, the inventor of the Diesel engine, used plant oil to run his first diesel engine in 1895. Rudolf Diesel demonstrated his new engine with peanut oil at the World Exhibition 1900 in Paris.
During the following years both, the engines and the fuel, made a development towards optimisation. So at present we have a big variety of modern Diesel engines, well otimised to use the standard diesel fuel.

Efforts to replace the fossil fuel diesel by plant oil as a renewable fuel started after the two energy crises in the Years 1973 and 1978. These efforts resulted in two different ways:

The efforts to create an special plant oil engine did not succeed in the mass production of such an engine. The Elsbett engine, which runs perfectly with plant oil, was opposed by the big car and engine manufacturers.
