Autoignition of Ethanol-Diesel Blends: Is it Worth Dehydrating Ethanol?
SSRN Electronic Journal, 2021 This study analyses the impact of the concentration of water in ethanol on the autoignition characteristics of ethanol-diesel blends. A constant volume combustion chamber was used to emulate the conditions of a diesel engine. Tests were carried out modifying the water content in the alcohol, and then the concentration of hydrated ethanol in the diesel ...
