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.

Abstract
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.
