TL;DR: In this paper , a revised variation disturbance method was proposed to evaluate the effect of methanol and ethanol on the combustion performance of primary fuels, and the results showed that ethanol has a more significant effect on improving the performance of gasoline than methanols.
Abstract: This paper proposes a revised variation disturbance method to provide valuable information and reference for fuel design or optimization of internal combustion engines to realize the comprehensive and quantitative evaluation of the effects of blending agents on the combustion performance of primary fuels. In this method, methanol and ethanol are blended into gasoline to form six kinds of alcohol–gasoline (E10, E20, E30, M10, M20, and M30). Then, the ignition delay, adiabatic flame temperature, component concentration, fuel-burning rate, extinction strain rate, and CO emission of gasoline and alcohol–gasoline are studied by system simulation in a wide range of operating conditions. Based on the new variation disturbance method, the effects of methanol and ethanol on the combustion performance of gasoline are next analyzed globally and characterized quantitatively. The comprehensive results of ethanol and methanol on the gasoline’s combustion are visually presented. The method proposed in this paper is preliminarily validated based on the analysis of the microscopic mechanism of combustion. The results show that the blending of ethanol and methanol has positive effects on gasoline combustion, and ethanol can rapidly ignite the gasoline in a wide range of operating conditions and is superior to methanol in terms of fuel combustion, stability, and pollutant discharge. Based on the treatment of simulated values of six combustion characteristics selected in this paper and the calculations of the variation disturbance method, the total disturbance values of ethanol and methanol to gasoline combustion are obtained as 0.8493 and 0.2605, respectively. That is, ethanol has a more significant effect on improving the combustion performance of gasoline than methanol. In addition, based on the analysis results of the combustion, it is found that the blending of ethanol enlarges the reaction of notable components in gasoline. This finding also proves the effectiveness and validity of the scientific method utilized in this paper.

TL;DR: The most effective pour-depressant additive additive are those containing such structural elements as an ester group in an aliphatic chain with olefinic bonds as discussed by the authors.
Abstract: 1. Straight-chain alkanes, when added to diesel fuel in amounts of 5% or more, harm the low-temperature characteristics of the fuel. The presence of these hydrocarbons will produce sharp increases in the cloud point, filterability temperature, and solid point of diesel fuels, and it is found that these three temperatures tend to converge when the n-alkanes are present. 2. The most effective pour-depressant additives are those containing such structural elements as an ester group in an aliphatic chain with olefinic bonds. The total molecular weight of such additives must be several times the molecular weight of the diesel fuel. 3. A given pour-depressant additive manifests identical effectiveness in fuels of a given hydrocarbon composition, including fuels with similar contents of n-alkanes.

TL;DR: An additive composition for use in a liquid fuel containing a mixture of alcohol, aromatic hydrocarbon, acetone, petroleum ether, and mineral oil is described in this article. But the additive composition is not suitable for the use in synthetic fuels.
Abstract: An additive composition for use in a liquid fuel containing a mixture of alcohol, aromatic hydrocarbon, acetone, petroleum ether, and mineral oil. The fuel additive is added to a hydrocarbon fuel to reduce pollutants and improve burning efficiency of the fuel. The treated fuel is produced by mixing a sufficient amount of additive to the fuel to produce the desired result.
