Finite element structural analysis on a single step NGVM pressure regulator body

Abstract

Vehicular emissions are the main contributor to urban air pollution. Recent years have seen social demands for reduced automobile exhaust emissions and alternative fuels available from energy resources. The impact of vehicular emissions can be considered in terms of health and environmental risks; that the pollutants cause when introduced into the air (Morawska, 2003). Emissions of green house gases (GHGs) are generally seen as a large problem since a temperature rise caused by the increasing concentrations of GHGs in the atmosphere is likely to influence global climate (Hekkerta, 2005).
