Design and Analysis of Poppet Engine Valve for Enhanced Mechanical Properties with Varied Geometric Parameters and Materials

Poppet engine valve is a precision engine component which blocks gas flow ports and controls the exchange of gases in internal combustion engines. The functionality of the valve is to seal the working space inside the cylinder against manifolds by continuously opening and closing of valve according to valve timing diagram. Existing difficulties with poppet engine valve being that it tend to fail due to fatigue after executing about 300 million operating cycles. Thus this research paper aims to establish effect of varied materials and Geometric parameters on mechanical properties of poppet engine valve to improve its performance over life and fatigue life using Ansys software
