: In current field of automotive industry enhancing the economy of fuel and emission reducing are the major challenges, the different fuels and novel combustion ideas are rising to face each pollution and fuel crises. Even though it late, the conception of homogenous Charge Compression Ignition, has been receiving extended attention, thanks to its potential for at the same time reducing fuel consumption, ox and especially Emissions. Specifically in HCCI engine analysis, wherever combustion is regarded to be a chemical-reaction-governed method, the value of correct chemical kinetic mechanisms and their machine potency is emphasized. Throughout this paper examines the Ethanol (C2H5OH), and also investigating trends of ignition method in a variable volume reactor for finding initial pressure, initial temperature and preservative fuels. This chemical experimentation of Ethanol was formulated in CHEMKIN using 57 species and 383 reactions for understating of analysis procedure characteristics of Combustion like cylinder pressure rise, ignition delay and formation of species characteristics were studied in HCCI engine and therefore the analysis was done by using COMSOL computer software code. The analyzed results exhibit that the water temperature of the fuel air mixture could be a potential standardization parameter for ignition. A rise in pressure resulted in a rise with in the species concentrations within the fuel-air mixture, leading to the conventional enhanced ignition times.
