“…Preliminary research from Wouters et al [20], conducted to evaluate the use of machine to measure temperature and pressure reported that methanol showed an atomization performance comparable to gasoline. Furthermore, under realistic engine operation, the penetration length of methanol spray increased due to the required injection duration attributed to the lower energy content.…”

“…In lean-burn operations, methanol achieved an impressive net efficiency of more than 45% and an extended limit of 0.1 units compared to gasoline [20]. Preliminary research has examined the potential use of methanol in combustion conditions with excess air, to determine the unique property of releasing hydrogen on evaporation with less fuel [26].…”

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.
