Computer Aided Modelling and Finite Element Analysis of Connecting Rod Fouling on Camshaft of DI Engine of Mahindra and Mahindra Tractor.

This paper provides the solution of live problem occurred in the engine of DI model of tractor of Mahindra & Mahindra by using the computer aided modeling and analysis techniques. The problem occurred in the connecting rod of engine which was fouling with the camshaft during operation. The main work is to model the components of engine with dimensions assemble those components and then simulate the whole assembly for each rotation of the crank. This will give the exact location of fouling and reason for fouling. The modeling software used is PRO-E wildfire 4.0 for modeling the engine components like camshaft, crankshaft, connecting rod, connecting rod bolt, nut, piston, etc. The analysis software ANSYS is used to analyze and simulate the whole assembly.
