Transient Simulation of Working Process for Four-valve Gasoline Engine

Abstract:

Software AVL-Fire was used to create the dynamic meshes of intake port and cylinder flow area of gasoline engine,in the strokes of intake,compression and expansion.The three-dimensional numerical simulation calculation was processed,and through the analysis of the distribution of air velocity,turbulent kinetic energy,temperature and pressure under different valve strokes,a more detailed flow field information was obtained,which provides a theoretical basis and reference to the design of the gasoline engine.
