Investigation of the Influence of Compression Ratio, Intake Air Temperature and Swirl in Intake passage on Random Cyclic Pressure Variations in Spark-Ignition Engines 2007-01-1831

Cycle to Cycle variations in Spark Ignition engines have increased our attention as reducing these Cycle By Cycle fluctuations will lead to better drivability, increased power output, better fuel economy, reduced emissions. As auto industry is growing at an alarming rate, numbers of users of automobiles are increasing day by day & strict emission standards have led people to think about the ways of increasing power with the same input. In this aspect evaluating the reasons for Cycle By Cycle variations has become the urgent need. In the present work, a C-program has been written to simulate the same and pressure crank angle diagrams are obtained, the results are plotted & analyzed so that the best operating conditions are developed. The results are validated through experiments.
