In this paper, a simultaneous design and development work for a diesel engine valvetrain system is presented. The rocker arm is one of the most important components of the valvetrain system which is transmitting the energy between the valves and the camshaft. Valvetrain system becomes even more complicated, when the extreme high speed of the system and nonlinear character of combustion is combined with the unpredictable behavior of the hydraulic lost motion mechanism during engine brake. As the complexity increases, it gets harder to predict valvetrain stress values especially while engine brake is in action. By taking all of these effects into account, that is reducing reliability of virtual analysis, requirement to conduct a strain measurement on valvetrain became inevitable.
