Abstract
In this paper are presented the results obtained regarding the dynamic loads from the crank mechanism (variation of the forces and of the moments related with the crankshaft’s rotation angle of the D-2402.000 engine, alternatively fueled with biodiesel obtained from used sunflower oil and diesel fuel), following the application of a calculation method developed in this way. At the elaboration of the calculation method it was taken into consideration the fuels’ physic and chemical properties, the constructive parameters of the engine, the working cycle and the best function conditions of the engine.
Keywords: Loads, Engine, Biodiesel
