Abstract
This report contains the result of practical studies of small scale pressing of rape seed oil and the running of a tractor with an Elsbett engine on Sjoesa farm. The report also contains a systems study of the production and use of rape seed oil as a fuel for vehicles in Swedish farming. Energy balances and economic calculations are included in the systems study. At Sjoesa farm 43530 kg of rape seed were pressed into 11360 litres of rape seed oil and 31505 kg of rape meal. The capacity of the oil expeller varied between 2.7 and 6.1 litres of rape seed oil per hour. Without preheating, the oil expeller consumes about 0.30 kWh electricity for each litre rape seed oil produced. Suitable sedimentation time for cleaning of the oil in a 0.6 m high tank is a little more than 20 days if the surrounding temperature is 15-20 degrees C. The tractor was a Valmet 805 with a three cylinder engine. This engine was rebuilt to an Elsbett engine. Engine power, fuel consumption and exhaust emissions were measured. The tractor has been driven in practical work for 339 hours. In the practical use, the tractor consumed ca 2440 litres

This corresponds to an average fuel consumption of 7.2 litres of rape seed oil per hour. In the engine dynamometer at Ultuna the fuel consumption of the Elsbett engine, on a volume basis, was measured to be 12% higher with rape seed oil than the diesel oil consumption is for an equivalent disel oil fuelled tractor. The Elsbett engine in the tractor had some running disturbances due to mechanical reasons. None of these running problems were caused by the use of rape seed oil as fuel in the engine. The cost for growing the oil crop varies from SEK 2 to almost SEK 20 per litre of oil between different oil crops and years. The production costs is about SEK 8.40 per litre of oil for summer rape which makes it difficult to compete with diesel oil at SEK 3.0 per litre. For (Abstract Truncated)}
