Design and analysis of exhaust manifold for multi-cylinder diesel engine with monolith catalytic converter using CFD

Abstract

This paper discusses the challenges in converting the existing multi-cylinder diesel ventilation system into an innovative model of the manifold with monolithic. Reactant gases after treatment of car engines are increasingly being used for the benefit of environmental quality, especially in the large metropolitan region of the country, through the use of exhaust systems to bring an end to their main pollutants. A well-conditioned exhaust system increases the performance of the engine. The performance of the manifold has a significant impact on engine efficiency. With the accelerated growth of modern technology and numerical methods, computer simulation has become a valuable method for research and development of fluid flow systems. The industrial CFD (Computational Fluid Dynamics) software was used to analyze the exhaust manifold system. In order to enhance the fundamental understanding of manifold operations, extensive knowledge was obtained on the flow property distribution and heat transfer. Various calculations were performed to research the parametric impacts of working conditions and math on the exhibition of manifolds. Proposals were made to improve complex plan and execution.
