Analisi Multibody di un sistema per il massimo sfruttamento della corsa del pistone Traditional Internal Combustion Engines are characterized by the presence of the crank mechanism. This solution is able to convert the linear motion of the piston, pushed by the combustion pressure, into a rotational motion. The crank mechanism is still used nowadays in all the ICEs. One of the main aspects of the crank mechanism is the output torque that is generated and its dependence on the crank angle. It is important to have in mind that the work done by the piston during its downward movement towards the BDC is not fully converted into useful work at the crankshaft. This effect is due to the different angles and positions the components of the crank mechanism assume during the operation. Based on this concept, my thesis is focused on the analysis of an alternative mechanism to be implemented in an ICE. The innovative system considered is based on Mr. Bertotti’s idea. Its system has the target to exploit in a larger amount the downward movement of the pistons and consequently obtaining an increase in the output torque from the engine. In practice, my job was to reproduce the mentioned engine mechanism in a 3D environment (SOLIDWORKS) and to simulate the working operation in order to verify the possible gain in the output torque of the system
