Impact of Methanol-Gasoline Fuel Blend on The Fuel Consumption and Exhaust Emission of A SI Engine
The 3rd International Conference on Advanced Materials Science and Technology (ICAMST 2015) , 2016
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.
The objectives of this work are to study the characteristic performance and pollutant emissions of the internal combustion engine using gasoline fuel and hybrid methanol-gasoline-blends (0%vol, 3%vol, 7%vol and 10%vol methanol). A fully functioning internal combustion engine experiment is built up for that purpose. The experiment setup includes a single cylinder four-stroke spark-ignition engine, brake and drive unit (BDU) that functions as a dynamometer, and a combustion engine basic module (CEBM) that functions as a display and control panel. For monitoring pollutant emissions, exhaust gas analyser with hand held remote operating unit is used to examine the carbon monoxide (CO), carbon dioxide (CO 2) and unburned hydrocarbons (HC) levels in exhaust gases of the SI engine. The analyser applies an interference filter correlation procedure using an infrared energy. The infrared energy in the test bench is transmitted through the flow of exhaust gases to a filtered infrared detector. A rotating chopper wheel cyclically interrupts the infrared rays and produces a sequence of signals. The analysis of the measured signals is done automatically by a microprocessor. Experimental results of the analyser as well as engine performance declare that when methanol is added into gasoline, the fuel blend contains more oxygen, which improves performance and reduces CO and HC emissions. Low fraction of methanol in methanol/gasoline blend (e.g., 10%vol methanol) can be used in SI engines without need to modify the engines.

In the present day scenario emissions associated with the exhaust of automobiles resulting in global warming is a major menace to the entire world and also detrimental to health. Here an experimental attempt has been made to know the level of variation of exhaust emissions (Carbon monoxide, Hydrocarbons, Nitrusoxides) in S.I. four cylinder engine by adding methanol in various percentages in gasoline and also by doing slight modifications with the various subsystems of the engine under different load conditions. For various percentages of methanol blends (0-15%) pertaining to performance of engine it is observed that there is an increase of octane rating of gasoline along with increase in brake thermal efficiency, indicated thermal efficiency and reduction in knocking. On the other hand exhaust emissions CO and HC are considerably decreased but CO 2 and No x simultaneously slightly increasing. It is notable that for these methanol blends combustion temperature is found to be high and exhaust gas temperature decreasing gradually.

It was reasoned that among the diverse mixes, the mix including M20 is the most suited for SI motor from the motor fumes discharge perspective.
Investigation Of Methanol Utilization In Ci Engines
MATEC Web of Conferences, 2018
The decrease in the fossil fuel resources and more rigid emission standards make the necessity to look for new fuels and technologies. One of the possible fuels can be the different alcohols. The oxygen content of the alcohols can improve the combustion process and reduce the emission rates of incomplete combustion products. The blending methanol (M) and ethanol (E) with diesel fuel is limited by separation. This article shows the research results and analysis of two typical solutions. First are blends of stabilized rape seed methyl ester (RME) to prevent the phase separation. The tests are carried out on a conventional TDI engine (VW 1Z) at different speeds and loads. Experimental results indicate that the addition of 10% methanol to 80% Diesel and 30% of FAME blend increased the unburned hydrocarbon (THC) with 60%, decreased CO emission with near 4% and the particulate emission (PM) with near 30%, the NOx emissions were near the same. The other technology is the dual fuel method. In this case, different amount of methanol is injected into the intake manifold. The tests are carried out with a conventional DI engine (IVECO AIFO 8031) at constant speeds and different loads and energy ratios. Experimental results indicate that the increase of energy ratio of the methanol at full load decreased NOx emission with up to 60% and the particulate emission (PM) up to 90%, while the CO and THC emissions increased extremely mainly at part loads.

To get extensive knowledge about the combustion behavior and emission benefits of a methanol-fueled internal combustion engine, a literature survey on recent academic research has been made and presented in this paper. Maximum 90% of methanol was effectively used in a compression ignition engine at high load conditions under dual fuel combustion technology. The methanol-fueled dual fuel combustion mode breaks a trade-off between the oxides of nitrogen (NOx) and the soot emissions which was the major problem existing in conventional diesel combustion (CDC). The methanol-fueled dual fuel combustion resulted in completely premixed combustion. The methanol blended with high cetane fuels improved the combustion rate due to the presence of oxygen content.

The aim of this study is to develop the one-dimensional model of a four-cylinder, four-stroke, multi-point injection system SI engine and a direct injection system SI engine for predicting the effect of various fuel types on engine performances, specific fuel consumption, and emissions. Commercial software AVL BOOST was used to examine the engine characteristics for different blends of methanol and gasoline (by volume: 5% methanol [M5], 10% methanol [M10], 20% methanol [M20], 30% methanol [M30], and 50% methanol [M50]). The methanol-gasoline fuel blend results were compared to those of net gasoline fuel. The obtained results show that when methanol-gasoline fuel blends were used, engine performance such as power and torque increases and the brake-specific fuel consumption increases with increasing methanol percentage in the blended fuel.

Automotive Experiences, 2021
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...
