The problem of possible pitting and cavitation in internal combustion engines is receiving considerable attention. Both theoretical and simulation simulation studies are carried out in order to understand the noise and vibration sources, using a force equation. For this work, the main aim is to actually study these vibrations and try to model it. A foundation is also laid to study cavitation and find possible ways of increasing the life of the engine components. A model to calculate pressure variation in the system is carried out using Modeling software, with the help of Finite Element Analysis and Fluid-Structure Interaction Analysis. Some important results have been shown with negative pressures leading to the fact that the developed models predict the presence of cavitation in the cylinder liner surface, stressing the importance of improving the piston and cylinder liner design.
