How Does One Measure Ethanol’s Octane? - Urban Air Initative
WebJan 6, 2013 · Straight ethanol has an octane rating of 130 (RON), 102 (MON) and a pump AKI rating of 116. Ethanol racing fuels, which are typically available as either E85 (85% ethanol) or E90 (90% ethanol) blends with gasoline, carry octane ratings of 110 to 116 depending on the other ingredients in the fuel. WebDec 1, 2024 · The addition of alcohol such as ethanol or methanol to gasoline can enhance air quality because it improves fuel combustion.

WebFeb 1, 2024 · Ethanol has a research octane number (RON) of 108-109 and a motor octane number (MON) of 91; both are higher than that of gasoline. In blending with gasoline, ethanol often exhibits significant non-linear response in octane ratings [7], [8], [9], [10], [11], and such response is recently found to be strongly affected by the blended fuel. WebJan 1, 2024 · Pure ethanol has a 35.7 %- mass of oxygen. Oxygen contents of the base gasoline RON 88, RON 90, and RON 92 were 1.54%, 1.01%, 0.76%, respectively. The oxygen content of the GE fuel blend has a linear correlation to ethanol’s concentration. The more ethanol is added, the higher oxygen content in the GE fuel blends. WebThe blending RON of ethanol is about 120-135, and the blending MON 100-106. The sensitivity (RON-MON) is typically 8-10 units for gasoline, but 14 units for ethanol. The high octane numbers of ethanol could enable optimization of engine to increase the thermal … Methanol is used in China as various blends ranging from M5 to M100 and in some … The results with ethanol bus is marked with red star.
