“…Since this decreasing engine output power value is obtained with the same amount of fuel, the BTE values of the engine are also decreased in the calculations. In the literature, some researchers have reported that due to the high evaporation temperature of bioethanol in the combustion chamber cannot be achieved in the homogeneity of the mixture so the use of bioethanol decreased BTE values [22,23].…”

In this study; 95 octane unleaded gasoline and bioethanol were tested as fuel in a spark-ignition engine by blending bioethanol with gasoline in certain proportions (2%, 4%, 6%, 8%, 10%). Tests were carried out at five different engine loads for a constant engine speed of 2500 rpm. The variations in engine performance parameters (engine torque, engine power, brake thermal efficiency, brake specific fuel consumption, brake specific energy consumption) and exhaust emissions (exhaust gas temperature, HC, CO, CO 2 and O 2) were investigated on the basis of test fuel and engine load. According to the test results, with the increase of bioethanol ratio in the blend, brake specific fuel consumption values increased by 9.71% and brake thermal efficiency values decreased by approximately 4.97% compared to gasoline. There was decrease up to 35.56% and up to 23.77% in HC and CO emissions respectively, and an increase by 6.01% in CO 2 emissions with bioethanol addition.

“…In the current study, BSFC increased by 3.67% and 1.97% for E5M5 and E10, respectively, compared to pure gasoline. Kamil and Nazal [56] found that decreases in BSFC of 10%, 14% and 18.4% in the cases of E6M6, M12 and E12, respectively. BTE is a measure how efficiently the engine converts the fuel's heat energy into useful mechanical work, which is expressed as a percentage.…”

Growing environmental concerns over global warming and depleting fossil fuel reserves are compelling researchers to investigate green fuels such as alcoholic fuels that not only show the concrete decrement in emissions but also enhance engine performance. The current study emphasizes the influence of different alcoholic fuel blends in gasoline on engine performance and emissions for an engine speed ranging from 1200 to 4400 rpm. The obtained performance results demonstrate that the brake power and brake thermal efficiency (BTE) increased with an incrementing blend percentage of ethanol and methanol in gasoline (EM). The minimum brake specific fuel consumption (BSFC) was ascertained using pure gasoline followed by E2 and then E5M5. The NOx and CO2 emissions can be described in the decreasing order of E, EM and gasoline due to same trend of exhaust gas temperature (EGT). CO results were in reverse order of CO2. HC emissions were found in the increasing order of E, EM and pure gasoline. E10 performed better among all blends in terms of less exhaust emissions and engine performance. However, EM blended with gasoline significantly reduced NOx. E5M5 produced 1.9% lower NOx emission compared to E10 owing to 1.2% lower EGT. Moreover, greenhouse gases such as CO2, which is mainly responsible for global warming reducing by 1.1% in case E5M5 as compared to E10.

In this paper, an investigation of the use of gasoline-ethanol-methanol on the spark ignition engine is presented, it is not common practice on public roads to use three fuels simultaneously in a spark-ignition engine. Using methanol reduces the ignition delay during combustion, especially at lean air-fuel ratios, and reduces knocking potential in small amounts. The best result ignition delay with value λ= 1,3 obtained in the E5M15 mixture with SoC occurred at 325 CAo, while the value λ= 1,0 also obtained on the same mixture with SoC occurred at 321,5 CAo. The CCV results indicate a more sloping increase in the COV (coefficient of variation) value when using GEM fuel, particularly with the addition of more methanol. The addition of methanol enhances combustion progression and improves the ability of the fuel blend to sustain combustion under lean conditions. Regarding the torque and power values, at λ= 1,0; 1,1; 1,2 are not significantly different, while the value λ= 1,3 is below the other λ values.
