Dynamic Analysis of Intake and Exhaust Valve Motion in a High-Performance four Stroke Engine. Part 2 - Development of a Numerical Model for the Simulation of the Valvetrain

This study develops a 1D GT-Suite© model of a four-valve, dual-camshaft racing engine valvetrain to accurately predict valve motion, including high-RPM phenomena such as float and bounce. The model is calibrated with experimental data and allows evaluation of subsystem behavior and component variations to optimize valve dynamics.
