“…The use of methanol alcohol, ethanol, and butanol results in high engine efficiency and torque [11,12]. The concentration of alcohol in the fuel increases the oxygen content in the fuel and improves the quality of combustion, thereby reducing CO and HC emissions of gasoline engines [13,14,15]. Also, the addition of alcohol reduces the ignition delay time thereby reducing the production of carbon monoxide and hydrocarbons increasing the fuel efficiency of gasoline engines [16].…”

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 methanol to fuel can reduce exhaust emissions better than ethanol and butanol.

“…Some alcohols such as ethanol and methanol can be used as both pure fuel and fuel additive [12]. There are advantages and disadvantages of using alcohol and ethers as a fuel additive [13]. The biggest advantage of alcohols is that their octane number is high.…”

Oxygenated fuel additives are added to gasoline in order to reduce the gases released from vehicle engines, to increase the octane number, and to expand the use of renewable resources. In this study, molecular and geometric analysis of oxygenated fuel additives was conducted theoretically and the energy values of optimized structures were calculated. The effect of molecular energy and the bond structure between C, H and O on the chemical and physical properties of some oxygen fuel additives were investigated. The obtained results will form the basis for future studies in obtaining more environmentally friendly fuels.

“…The maximum power of the fuel blend with the additive is on M15-9 where the brake power is 51.7 kW at 5900 rpm. The presence of methanol increases the mass injected into the engine [24][25][26]. In this case propylene glycol increases the brake power of the gasoline-methanol blend if added with the right composition.…”

The researches on fuel alternative for the spark-ignition engine are currently conducted intensively, including the use of methanol-gasoline blend. One of the problems faced against the use of this fuel is the decreasing of engine performance. In this research, the use of the additive in a spark-ignition engine fueled with methanol-gasoline M15was investigated. The purpose of the research was to find an additive that could overcome the decrease of power and torque of an engine fueled with M15 methanol-gasoline blend. So, the study was intended to determine the effect of additive on the engine torque and power, as well as to find the best additive composition which produced relatively the same performance if compared with the pure gasoline engine. The measurements were performed by using a 1200 cc electronic fuel injection car that has maximum power and torque of 51.7 kW and 84.5 Nm, respectively. The engine was tested on a roll chassis dynamometer equipped with an engine scanner and the acquisition data system. The composition of the additive being tested was between 3 to 10 cc/l. It was found that the power and torque relatively unchanged on the additive composition of 9 cc/l. It can be concluded that the engine performance can be kept up by adding the propylene glycol as an additive for methanol-gasoline blend. Therefore, through this study, a method has been found to overcome the decrease in power and torque of an engine fueled with M15 methanol-gasoline blend.
