The paper introduces a new valve dynamics simulation progra..-n called KV-DYN.Unlike existing convcntionai programs KV-DYN uses a now model taking non-steady valve ilow into account.Basic equations have been established on the basis of large-scale model experiments and simulation results have been validated.Two new non-dimensional parameters.characterising a compressor-valvearrangement arc introduced: Relative spring strength and compressibility related valve !ate closing number.These allow to overlook the influences of all relevant quantities.Another novelty in KV-DYN is the so-called stability diagram.This enables predictions to be made as to the probable incidence of valve nutter.
