Abstract
The non-transformed vegetable oil applications as fuel on Diesel engines are frequent. However, the utilization of these oils without criterion causes damages to engine. The literature shows that has a great variability of results, which are directly related with the vegetable oil quality, production and purification processes, utilization criteria and engine technology in which the oils were tested. In this work, an essay was performed with a diesel engine fueled with crambe oil preheated at 100°C, with application of an average load of 51% of the rated power, aiming to evaluate the lubricant. At time zero and each 15 hours of engine working, the lubricant was sampled for physico-chemical analysis, and it was completely replacement after 50 hours, according to manufacturer’s recommendation. The essay had duration of 100 hours, totalizing 7 samples. The physico-chemical analyses of the lubricant indicate that the fuel combustion was adequate, because there are not indications of lubricant contamination by the fuel. However, on first 50 hours, was observed high iron contamination. It should be noted that important properties of the lubricant were not significantly altered.
