Abstract:

Abstract The properties of gasoline change as a result of blending with an alcohol. The aim of this paper is to report new experimental data on distillation curve and Reid vapor pressure of pseudo-binary blends of a catalytic reforming gasoline with ethanol, i-propanol and n-butanol, respectively. Gasoline blend with ethanol was used as reference for discussing properties of isopropanol and respectively, n-butanol blends with gasoline. The main conclusion is that alcohol addition to gasoline affects the relevant characteristics of the blend that influence engine operation. Gasoline+i-propanol

Abstract:

The aim of this work was to describe the density and viscosity and water tolerance of 1-butanol-gasoline blends. Density and viscosity of 1-butanol are higher than that for gasoline and they can affect these parameters in the final gasoline blend. Density increases linearly and viscosity exponentially with the content of 1-butanol. Water solubility in 1-butanol-gasoline blend was determined as the temperature of a phase separation. The water was separated in the solid form at negative temperature and the phase separation point was determined as the temperature of crystallization. Influence of

Abstract:

Although alcohols have been considered and used as fuels for internal combustion engines for decades, their use in automotive transportation systems has been rather limited. In the past few years, ethanol has received varying amounts of attention in the United States owing to the increasing cost of gasoline fuel and legislative mandates in some states requiring the sale of alcohol-blended gasoline for light-duty vehicles. This may, in the end, help the agricultural economy in the United States. If alcohol blends are to be used in spark ignition (SI) engines designed to operate on gasoline, the

The use of ethanol/gasoline blends on gasoline engines is not only a potential solution for satisfying the fuel demand but also for reducing emissions from vehicles which cause environmental pollution and adverse health effect. In Vietnam, the blend with 5% of ethanol (E5) has been widely used. However, blends with higher than 5% of ethanol should be studied and applied in order to improve the ability to substitute for gasoline.

Abstract:

The performance comparisons of engine fueled with butanol/gasoline and ethanol/gasoline blends were tested. It was indicated from the experimental results that, compared with pure gasoline, power and fuel economy of engine fueled with butanol/gasoline and ethanol/gasoline blends reduced slightly, while HC and CO emission reduced significantly, and NO emission increased. It can be concluded that, the performance of engine fueled with butanol/gasoline blends was better than ethanol/gasoline blends, and B20 was better than B30.

Abstract:

To address the growing gap between energy demand and availability, the need for biofuels has become increasingly urgent. Biofuels offer a renewable energy source while significantly reducing or even eliminating net greenhouse gas (GHG) emissions. Ethanol, commonly produced through biomass fermentation, has emerged as a promising alternative to gasoline due to its advantageous combustion properties, including a high octane rating and inherent oxygen content. Despite its expanding use, a key research gap exists in evaluating the compatibility of internal combustion engines with ethanol or ethano

Abstract:

In recent years, one of the most logical efforts made to reduce the dependence on fossil energy sources is the use of a gasoline-methanol fuel blend. However, the problem in using a gasoline-methanol blend as fuel is that the methanol will eventually separate itself from the gasoline unless they are properly blended together, this is because methanol has a polar hydroxyl group called monohydric that binds water vapor together, causing the mixture to separate. Previous research showed that adding a small amount of ethanol to the gasoline-methanol blend makes it a homogeneous blend. Therefore, t

As alternatives for gasoline, ethanol and recently 2,5-dimethylfuran (DMF) have been investigated for their different properties. Lubricity analysis of fuels in fuel systems is vital because of the lubricating role of fuel. Lubricity of gasoline and its alternatives became important since introduction of direct-injection gasoline fuel pump with high injection pressure becoming closer to diesel pumps. Therefore, this work examines the lubricity properties of gasoline and its blends with alternative fuels using

Abstract:

Now days, the use of fossil fuels is still the most widely used energy source. This condition causes its availability to start depleting and it has an impact on worsening air quality. Biofuel can improve air problems when used as a substitute or mixture of fossil fuels. Methanol is a potential candidate because it is cheap and easy to produce. The problem of gasoline-methanol fuel blends has been solved by adding a certain amount of ethanol. But the combustion speed characteristics have not been disclosed which is one of the urgent properties of SI Engine fuel. This study aims to measure the c

Abstract: Finding substitute fuels has been more popular in recent years as a response to escalating pollution levels and fuel shortages. The goal of this research is to find the ideal gasoline to ethanol ratio that will maximize engine performance and reduce emissions in spark ignition engines. In order to analyse the performance of different blending ratios, the research looks at metrics such carbon monoxide (CO) emissions, brake power (BP), brake specific fuel consumption (BSFC), and brake thermal efficiency (BTE).

In today’s world we see that the demand for gasoline and cars keep increasing and one problem which is significantly seen is that we either opt for a fuel which provides higher performance or for a fuel which provides lesser emissions. In this study we aim to provide higher performance and lower emissions by combining two chemicals or octane boosters, namely ethanol and toluene with gasoline and find out its performance and emission characteristics when compared with traditional gasoline and ethanol-gasoline blend.

Abstract:

In the modern industrial field, there is a strong emphasis on energy-saving and emission reduction. Increasing the amount of ethanol in ethanol–gasoline blends has the potential to replace fossil fuel gasoline more effectively, improving energy efficiency and lowering emissions. The interaction between liquid fuel film generation on the piston crown and spray impingement in the combustion chamber in the setting of GDI engines has a substantial impact on particle emissions and engine combustion. In this study, 92# gasoline and ethanol by volume are combined to create the ethanol–gasoline blend

Emissions levels for CO, NOx, and unburned fuel (UBF) from a stationary four-cylinder Chrysler engine were measured under a variety of operating conditions for gasoline and three different 20 vol percent alcohol-gasoline blends. In tests of separate isobutanol, ethanol, and methanol blends, lower CO and NOx emissions were observed for the alcohol blends relative to gasoline, particularly for fuel-rich operation. Generally, on a volume (mole) basis unburned fuel emissions were highest for methanol blends and lowest for gasoline, but on a mass or OMHCE basis only small differences were noted. Fo

Our experimental approach involved using a rapid compression and expansion machine (RCEM) to achieve elevated temperatures and pressures. The fuels containing different volumes of oxygenated hydrocarbons were burned at equivalence ratios of 1.0 or 0.7, an initial temperature of 340 K, and initial pressures of 0.10 or 0.05 MPa. To simulate knocking phenomena, we installed a rectangular channel in the combustion chamber of the RCEM and measured the pressure history
