Corresponding Author: Hakan ÖZCAN-ABSTRACT-An experimentally study were carried out to investigate the effect of methanol and/or ethanol blends with gasoline on the combustion characteristics,engine performance and pollutant emissions. The blends including up to 15% by volume of alcohol and pure gasoline were used as test fuels in a four stroke, single cylinder, spark ignition (SI) engine. Experiments were performed at similar operating conditions under wide open throttle (WOT) operating conditions with varying engine speeds between 1200 and 1800 rpm. The test results showed that the average change in engine brake power, brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), volumetric and combustion efficiencies within all engine speed and all blends rates by 4.63%, 4.91%, 1.46%, 13.5% and 0.27% for methanol-ethanol-gasoline blends, respectively. The calculated average reduction for all speeds and all blends rate in CO, HC, and NOx emissions were found as 7.56%, 16.02% and 8.17% for methanol-ethanol-gasoline blends, respectively. The results demonstrated that the pure gasoline has minimum cylinder pressure than blended fuel and increasing the rate ethanol and/or methanol in blends resulted in an increase of the maximum cylinder pressure. It was found that the alcohol content increases in the fuel blend caused also the higher the heat release rate (HRR) and thus the shorter the combustion duration. In addition, the ignition timing for the alcohol blends advanced to achieve maximum brake torque (MBT) conditionsI. INTRODUCTION Developing alternative fuels for internal combustion engines is one of most attractive research topic for scientist and engineers.The use of alcohol and their blends as fuels has been a popular subject of research sincethe 1970s[1-5]. Currently, alcohols are the most popular additives as octane boosters and as a partially oxidized fuel in gasoline fuel. In literature, there are several recent studies on the usage of ethanol andmethanol blending with gasoline in SI engines[6-18]. In some studies, the effects of methanol blends with gasoline on the performance and exhaust emissions of SI engines were investigated [6,9,14]. M. Abu-Zaid et al.[6]found that the methanol mixture has a significant impact on improving the performance of SI engines and also increases the octane number. Bilgin and Sezer [9]concluded that M5 fuel blend was given the maximum brake mean effective pressure (BMEP). Shenghua et al. [14]concluded that the methanol ratio increase in the gasoline blends decreased the engine power, and torque while the BTE increased. In other some studies, the effects of ethanol blends with gasoline on engine performance and exhaust emissions were investigated [10,13,15]. Koc et al. stated that the engine torque, power, and BSFC increases, while the emissions of CO, NOx and HC decreases with the higher ethanol concentration in the blends compared with the gasoline. Schifter et al. [15]investigated the effect of ethanol-gasoline blends containing up to 20vol% ethanol on engine performance and exhaust emissions.They found that ethanol in the blends of 20 vol% was slowed down the rate of burning and the cyclic variation was increased.Another study reported that the use of hydrous ethanol cause higher BSFC and higher thermal efficiency than the gasoline-ethanol blend for the range of all operating speeds[10].The effects of methanol and/or ethanol blended gasoline on engine performance and exhaust emissions have investigated in a number of studies [19-22]. In a limited number of studies, the effect of ethanol and methanol blends with gasoline on the combustion characteristics of SI engines have investigated [15,20].The effects of adding at low ratios of methanol and ethanol to gasoline on thecombustion characteristics, engine performance and exhaust-gas emissions were experimentally investigated[19].Their results showed that the ethanol-gasoline blends have higher BSFC compared with pure gasoline. They also found that the combustion pressure rise was noted to occur later than gasoline fuel, and the lowest peak heat release rate was obtained in the gasoline study.Balki et

India is a developing country with an increasing workforce. A large part of transportation, movement etc depends on SI engines. Even agriculture today is largely dependent on SI engines. However in recent past we have witnessed a rapid increase in petrol prices. This price rise has not only affected commuters but also farmers and industries. Today's fuel research is completely based on finding alternative fuel, however more availability of heat from fuel is not acceptable. It is the ability to transform into mechanical work that matters the most. Meanwhile until some substitute is chalked out, researchers are Concentrating on petrol blends (generally alcohol blended). Although a variety of alcohols can be chosen, it has been found that heat from ethanol can be transformed to mechanical work more efficiently. In this paper, facts supporting use of ethanol and petrol blends have been discussed. Results obtained from experimental tests have been discussed too. Internal combustion engine are the most preferred prime mover across the world. Spark ignition engine is preferred locomotive prime mover due to its smooth operation and low maintains. The gasoline is fossil fuel which is limited in reservoirs causes varieties of study in search of alternative fuel for SI engine, where alcohol promises best alternative fuel. In this paper study of three alcohols are tried to investigate in two parts. Comparative study of methanol, ethanol and butanol on the basis of blending percentage is first part, followed by investigation of oxygen role on the basis of oxygen percentage in the blend. The result shows highest replacement of gasoline by butanol at 5 % of oxygen content, the performance of same oxygen percentage for other two alcohols are also better. Presence of oxygen gives you more desirable combustion resulting into low emission of CO, HC and higher emission of CO2 as a result of complete combustion, higher temperature is also favorable for NO emission resulting higher emissions for it

This study is concerned with investigating experimentally the effects of methanol and Methyl tert-Butyl Ether (MTBE) blending to base gasoline on the performance CO emissions and fuel cost of a spark ignition (SI) engine. The fuel blends were prepared by addition 5, 10, 15, and 20 vol % of methanol and MTBE with a specified amount of base gasoline. The methanoland MTBE-gasoline blends were designated as M5, M10, M15, M20, and MTBE5, MTBE10, MTBE15, MTBE20, respectively. Experiments were conducted under various engine speeds, spark timings (STs), and compression ratios (CRs). The engine was operated under wide-open throttle conditions. The results of the study showed that the M5 and MTBE10 blends yield the best engine performance in terms of the brake mean effective pressure (bmep), while the M20 and MTBE15 blends are the best performers in terms of brake thermal efficiency (bte). Moreover, M20 and MTBE10 blends give the minimum CO emission values. The economical analysis performed i...

In this study, the effects of methanol–gasoline (M5, M10, M20, M30 and M50) fuel blends on the performance of a spark ignition (SI) engine were investigated. In the theoretical study, the four-cylinder, four-stroke, multi-point injection system SI engine was used. The results obtained from the use of methanol–gasoline fuel blends were compared to those of gasoline fuel. The results indicated that when methanol–gasoline fuel blends were used, the brake specific fuel consumption increased and engine performance parameters such as torque and power increases with increasing methanol amount in the blended fuel.

The increasing volume of motorized vehicles leads to an increase in dependence on fossil fuels and an increase in air pollution. The problem can be reduced by utilizing renewable alcohol fuels such as methanol, ethanol, and butanol. The high number of octane and oxygen content is the main reason. Therefore, this study aims to observe the exhaust emissions of the 160 cc gasoline engine with a mixture of methanol, ethanol, and butanol. The percentage of alcohol used is 0 % to 30 % by volume. The test was carried out in 2000, 3000, and 4000 rpm. The results of the study explained that the use of methanol, ethanol, butanol in the fuel mixture was proven to reduce exhaust emissions. CO and HC emissions decreased as the percentage of alcohol in the fuel increased. The highest reduction in CO and HC emission in methanol blended fuel was 30 %, 94.55 % and 82.71 %, respectively. Meanwhile, CO2 emissions increased by 34.88 % at 2000 rpm engine speed. Based on this test, the addition of methan...

In this study, the effect of methanol-gasoline fuel blend (M15, M30 and M50) on the fuel consumption and exhaust emission of a spark ignition engine (SI) were investigated. In the experiment, an engine four-cylinder, four stroke injection system (engine of Toyota Kijang Innova 1TR-FE) was used. Test were did to know the relation of fuel consumption and exhaust emission (CO, CO2, HC) were analyzed under the idle throttle operating condition and variable engine speed ranging from 1000 to 4000 rpm. The experimental result showed that the fuel consumption decrease with the use of methanol. It was also shown that the CO and HC emission were reduced with the increase methanol content while CO2 were increased.

In this study, the performance parameters are investigated for a single cylinder, four-stroke, spark-ignition engine with varying speed (1000 to2500 rpm) with compression ratios (CR=8). For this analysis, (base fuel) and blends of ethanol with base fuel (E10, E20) and methanol with base fuel (M10 & M20) are used. The results show that the exhaust temperature increases with the increase in engine speed for all the tested fuels. lost of heat energy with exhaust were decreased and exhaust emissions were reduced with the increase of ethanol and methanol-gasoline blends content.
