Assessment of ethanol autoxidation as a drop-in kerosene and surrogates blend with a new modelling approach

Abstract

Autoxidation of real and surrogates kerosene was evaluated using PetroOXY method.• Ethanol addition decreases the induction period of real kerosene while increases that of surrogates.• Nine antioxidants were assessed to improve the thermal stability of ethanol.• A new method for modelling PetroOXY test is proposed.

Characteristics of SI engine fueled with BE50-Isooctane blends with different ignition timings

“…Furthermore, because the composition of the ethanol compound (see Table 1 ) makes it more soluble and oxygenated in isooctane [ 8 ], and because of the heat of vaporization, and low vapor pressure, bioethanol can be converted into a renewable fuel [ 9 – 11 ]. On the other hand, when compared to biodiesel [ 12 ], bioethanol has lower greenhouse gas emissions and production costs and has a more profitable future evolution; thus, bioethanol and its mixtures (gasoline, isooctane) have great potential to be used as renewable fuels, especially in SI engines and in modern vehicles [ [13] , [14] , [15] , [16] ]. In addition, a recent studies on the effect of a mixture of ethanol and isooctane on laminar burning characteristics [ 17 – 19 ], octane reaction on the methyl tert -butyl ether (MTBE) with gasoline [ 20 ].…”

Artificial Neural Network-Based Modeling of Performance Spark Ignition Engine Fuelled with Bioethanol and Gasoline

“…The highly efficient use of bioethanol in spark ignition engines (SIE) is attributed to its low sulfur content and flammable properties, rendering it a viable alternative fuel [1]- [3]. Therefore, numerous research efforts have been undertaken to develop suitable models and configurations for the fuel system and the spark ignition engine (SIE) using bioethanol.…”
