In modern research, computer simulation has become a powerful tool for IC engine performance prediction as it saves time and is also economical. A proposed theory or an innovation can be analyzed quickly using a computer and the setting up cost for an experimental work can be postponed until optimization is achieved. For the purpose of evaluating performance of direct injection diesel engine operated with neat oxygenated fuel, the literature data were found confined to experimental investigations and insufficient to serve the purpose because of the large number of oxygenated fuels available for testing. Any improvement predicted in the combustion of the engine fuel will enhance the performance and reduce the emission simultaneously. Therefore oxygenated fuel combustion predictive capability is a acquit necessity at this point of time to screen the oxygenated fuels for better performance.

The increasing demand for higher specific power, fuel economy, Operating Costs as well as meeting global emission norms have become the driving factors of today’s product development in the automotive market. Substitution of high-density materials and more precise adjustment of material parameters help in significant weight decrease, but it is accompanied by undesirable cost increase and manufacturing complexity. This becomes a challenge for every automotive engineer to balance the above parameters to make a highly competitive design. This work is a part of the Design and Development of 2.2 L, 4 Cylinder TCIC Diesel Engine for a whole new vehicle platform, concentrated on automotive passenger car operation. This paper explains the selection of a suitable cylinder head gasket technology for a lightweight engine that acts as a sealing interface between the cylinder block and cylinder head.
