ICM Data & Background Research 2013-01-1635: An Overview of the Effects of Ethanol-Gasoline Blends on SI Engine Performance, Fuel Efficiency, and Emissions 2013-01-1124: Fuel Composition Effects On Particulate Emissions in Direct Injection Spark Ignition Engines 3
4
Introduction to Ethanol Ethanol as a Fuel Octane is predictable Vapor Pressure is predictable Cooling Effect is 4X gasoline Distillation changes to gasoline is predictable Good Hydrogen/Carbon Ratio and Mole fraction Bio-Degradable with very low toxicity Positive Carbon Balance Value 4
5
Octane, Does It Matter? Octane Performance over measured Octane Measured Octane (Blending Value) E0 to E30 = +14 Octane E30 to E98 = +7 Octane 5
6
How to Improve Efficiency 6 SAE 2012-01-1277 Effects of Heat of Vaporization, Chemical Octane, and Sensitivity on Knock Levels for Ethanol-Gasoline Blends Increased Efficiency is achieved by increasing the working pressure of each combustion event: Octane allows the increase of overall efficiency increase. Sensitivity allow a wider range of overall efficiency when optimized (horizontal)
