“…The results showed that engine torque and power decreased, whereas the brake thermal efficiency improved with the increase of methanol percentage in the fuel blend. Other authors [16] have studied the influence of methanol-gasoline blends on the gasoline engine performance. The results showed that the highest brake mean effective pressure (BMEP) was obtained from 5% methanol-gasoline blend.…”

During the last years, concerns regarding climate change, decline of energy security, and hydrocarbon reserves have resulted in a wide interest in renewable alternative sources for transportation fuels. Methanol and ethanol have been possible candidates as alternative fuels for the internal combustion engines because they are liquid and have several physical and combustion properties which resemble those of gasoline. Therefore, the aim of this study is to develop the one-dimensional model of a gasoline 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, ethanol, and gasoline (by volume). A comparison was made between the results gained from the engine simulation of different fuel blends and those of gasoline. They show that when blended fuel was used, the engine brake power decreased and the BSFC increased compared to those of gasoline fuel. When blended fuel increases, the CO and HC emissions decrease, and there is a major increase in NOx emissions when blended fuel increases up to 30% M30 (E30). Increase in the percentage of ethanol and methanol leads to a significant increase in NOx emissions.

“…Currently, alcohols are the most popular additives as octane boosters and as a partially oxidized fuel in gasoline fuel. The influences of methanol, ethanol, or their mixtures with gasoline on the performance parameters, combustion characteristics and exhaust emissions of SI engines were extensively studied in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In one of these studies, the effects of added methanol into gasoline on engine performance was investigated in an SI engine by Abu-Zaid et al [1].…”

The effects of oxygenated fuel additives have been investigated based on the second law (exergy analysis) of thermodynamic in an SI engine. Exergy terms such as the total cylinder exergy, exergy transfers via heat transfer and work, fuel chemical exergy and irreversibility were computed for closed part of the engine cycle. Additionally, the exergy distributions, the brake power, brake specific fuel consumption (BSFC), first (energy) and second law (exergy) efficiencies were determined. The experimental data, especially the measured cylinder pressure data, were used to calculate the exergy terms with a homemade code. Test results showed that when compared with gasoline operation, the peak cylinder pressure for M10, E10, and S10 was increased by 18.65%, 12.75% and 15.52%, respectively, and also shifted towards to TDC. In addition, the energy and exergy efficiency decreased with the addition of methanol, ethanol, and solketal. The maximum reduction in the exergy efficiency occurred for the S10, and this reduction was determined as about an 8.42%. The results also revealed that the gasoline blends containing 10% methanol, ethanol, and solketal were an unfavorable choice from the secondlaw perspective, due to the reduction in the exergy.

“…Methanol (CH3OH) and ethanol (C2H5OH), regarded as the most attractive alternative alcohol fuels for spark ignition engine, have some similar advantages over gasoline. They have excellent combustion properties and better antiknock characteristics [7,8]; moreover, supplying same amount of energy rather than quantity as gasoline, the two alcohol fuels could not only keep and even improve the original engine power but also improve the thermal efficiency and reduce the regulated emissions of hydrocarbon (HC), carbon monoxide (CO), and oxides of nitrogen (NO,) [9][10][11][12][13][14]. However, unbumed CH3OH and C2H5OH are emitted when the engine runs on the alcohol/gasoline blends [14,15], especially the CH3OH is a toxic pollutant.…”

“…The regulated emissions characteristics of alcohol/gasoline blends fueled spark ignition engine have been adequately studied under various working conditions throughout the world [9][10][11][12][13][14][15], and the researchers have obtained a consensus that the addition of alcohol into gasoline could reduce the volumetric emission of HC, CO, and NOx pollutants. A few literatures focused on the alcohol emissions of spark ignition engine [16][17][18][19].…”

Methanol (CH3OH) and ethanol (C2HSOH) are generally called alcohol. They can be mixed with gasoline to fuel SI engine. The fuel blends of alcohol and gasoline are named gasohoi. Alcohol emission characteristics and the contributions of fuel on hydrocarbon (HC) emission were experimentally investigated on a three-cylinder, electronic controlled, spark ignition JL368Q3 engine when it ran on 10 (v/v) %, 20 (viv) %, and 85 (v/v) % methanol I gasoline and ethanoll gasoline fuel blends. Experimental results show that, the value of alcohol emission rates (g aicohoi emission per kg alcohol fuel, glkg.) is a decreasing exponential function of exhaust temperature with high correlation: regardless of the alcohol fraction in fuel blends, the CH3OH emission rate is no more than 8%, while that ofC2HsOH no more than 35%. The emission rate of nonalcohol HC was one grade higher than the alcohol emission rate: the minimum HC emission rate occurs at middle and high engine loads, it is around 40% for methanol/gasoline blends and about 50% for ethanol/gasoline blends. Gasoline is the main source ofHC emission of gasohoi engine, methanol contributes no more than 8% while ethanol no more than 25% on HC emission.
