Recently, the environmental issues on an earth scale and the depletion of energy resources are requiring internal combustion engines to improve fuel economy and to reduce NO_x emissions and particles urgently, which cause mainly atmospheric pollution. For this purpose, an alternative fuel and new combustion techniques have been studied so far. In this context, the interest in using alcohols as an engine fuel has increased. Among the various alcohols, Ethanol is known as the most suited fuel for spark-ignition engine. The most attractive features of Ethanol as an SI engine fuel are that Ethanol can be produced from renewable energy sources such as agricultural products and it has high octane number. Ethanol can be used in SI engines as pure or blending with gasoline. For pure Ethanol some modifications on engine design, where it can be used in SI engines by blending with gasoline at low concentrations without any modification. As the combustion properties of Ethanol, however, differ from those of gasoline fuel, it is necessary to investigate the combustion characteristics of Ethanol and the effects of Ethanol addition to gasoline in detail for the proper application of Ethanol to a new internal combustion engine. The main purpose of this work is to measure the laminar burning velocity of Ethanol and clarify the effects of Ethanol addition on octane combustion properties.
