Design and Analysis of Exhaust Manifold in Diesel Engine
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
This project aims in re-designing an exhaust manifold by determining the thermal stresses and deflections exhibited under various operating conditions with different materials and temperatures. The objective is to ensure the suitability of the design for a particular material from the view point of reliability and serviceability. Defects in existing manifold are cracks usually occur due to prolonged exposure to extreme temperatures, defects in casting and repeated heat cycling. Welded regions and the curved profiles are the critical regions of failure. A methodology is developed to ensure the best suited design and material for the given operating conditions. Manifold behavior for Cast Iron is analyzed. Redesigning the curved profiles can reduce the turbulence effect of the exhaust gases on the welds. High-end CAD/CAM software such as Cero3.0 and ANSYS 14.0 are used for modeling and analysis.
