Design and Analysis of Camshaft in Six-Stroke Internal Combustion Engine

An I.C. engine (internal combustion engine) commonly utilizes a four stroke operation process in engine including as an intake process, compression process, expansion process, and exhaust process and in addition to this four stroke process, in addition of a secondary process, add two additional strikes for scavenging process which installs a fresh air to intake stroke and exhaust stroke to exhaust for any remaining burnt and un-burnt gases from the combustion chamber. It is also estimated that about 35 percent of fuel energy is lost in exhaust of engine and 30 percent in cooling down of engine. Out of the remained 35 percent of energy of the fuel about 50 percent of energy gets converted into the work. Two extra additional strokes have to be added for increase the thermal efficiency and better utilization of the fuel. The modelling of a camshaft for six stroke engine created by using computer aided design (CAD).Finite element analysis (FEA) is performed to analysis critical locations of the camshaft using the ANSYS software. This analysis performed for find out critical location of camshaft during load conditions.
