Analysis of Diesel Engine Turbocharger & its Optimization

In general the engine operates as a naturally aspirated engine. The combustion air is drawn directly into the cylinder during the intake stroke. In turbocharged engines, the combustion air is already pre-compressed before being supplied to the engine. The engine aspirates the same volume of air, but due to the higher pressure, more air mass is supplied into the combustion chamber. Consequently, more fuel can be burnt, so that the engine's power output increases related to the same speed and swept volume. An effort has been made to carry out the analysis of “Turbocharger�. The project requires a basic knowledge of the analysis software and the working of the turbo charger. This is a complicated task, so to solve such problem COSMOS is the most preferred software tool, which has no boundary limit for analysis. Here Structural type of analysis carried out for the turbo charger. The report includes a general overview of the Turbocharger, CAD systems, FEM, the introduction to COSMOS. The final section of the documentation deals with the comparison of manual design results with the results obtained from the use of analysis software and a brief idea of the future scope of analysis using COSMOS software for the turbo charger.
