Dynamic Analysis of a Valvetrain System

The mathematical modeling of the dynamics of a mechanical system is a powerful tool for the engineer predicts the behavior of the system. In the design of intake and exhaust valvetrains of diesel engine, the dynamic analysis of the system is essential for the proper sizing of the components. Through dynamic analysis of a 1D model using the Simulink software, this paper will describe the behavior of a valvetrain system that uses an exhaust rocker with hydraulic lifter.
