Finite element analysis of piston engine block and exhaust muffler of an internal combustion engine using simulation technique

Abstract

Internal combustion engines have been playing a vital role and will remain an active area of engineering education and research in future. Most of the researches in internal combustion engines are of operating performance and fuel performance improvement oriented. Almost all of the components in an internal combustion engine are subjected to heat loads. Every mechanical component Piston, Engine block, Exhaust muffler have been designed for a particular structural and heat strength. Piston seizure and cylinder block melting are typical problems when heat and structural loads on the components exceed the design strength. In the current study attempt has been made to simulate the physical working conditions of components of an internal combustion engine. The analysis is virtual simulation (because it was carried out with the help of a digital computer and a software tool-ANSYS 17). The current study emphasizes on stress, strain, temperature, heat flux, thermal gradient distributions in the component Piston, Engine block and Exhaust muffler materials. CREO was used for the solid modeling of engine components and ANSYS 17 was used for the analysis. The study was carried out on prime components of an internal combustion engine such as Piston, Engine block, Exhaust manifold and Exhaust Muffler. Piston and Engine block were subjected to structural and thermal loads and connecting rod subjected to compressive gas loads, Exhaust manifold and exhaust muffler were subjected to study heat and fluid flow loads. Peak stress, deformation and temperature profiles were a matter of concern when analysis carried out in piston, engine block, and exhaust muffler. Velocity, temperature, and pressure distributions are a matter of concern when analysis carried out on exhaust manifold and exhaust muffler. newlineThe very basic intention was to simulate the working conditions of the engine components virtually for different loading conditions, for different component geometries, and for different component materials [15].
