Summary:

This work shows a case study of a cavitation problem in a heavy duty diesel engine. We propose to solve this cavitation problem by studying the piston secondary motion. The first step was to simulate the piston secondary motion in order to evaluate the piston excitation against the liner that could cause the high frequency vibration. The second step was to optimize the piston secondary motion by changing pin offset. The solution proposed in this work was tested in the engine and the cavitation problem was solved. It was studied also the solution robustness for pin offset manufacturing tolerance. After opmizing the pin offset it was performed also a piston profile optimization
