“…The results were consistent with previous research about alcohol addition. 26,27 When run on blended fuels, the engine's exhaust temperature was lower than on E10 with or without EGR. With the increased blending ratio, the temperature of the engine exhaust gas further decreased.…”

“…However, butanol exerts some negative effects on the engine including cold start issues. Although the low heating value (LHV) of n -butanol is high relative to ethanol or methanol, it is still lower than that of gasoline, resulting in a fuel consumption penalty in high-proportion butanol–gasoline blends …”

Butanol is attracting more attention as an alternative fuel. The performance and emissions of butanol/ethanol−gasoline (E10) was investigated in a spark ignition engine. Exhaust gas recirculation (EGR) was employed to improve the engine performance and emissions in this reported test. The experimental results showed that high brake thermal efficiency (BTE) was observed with a high proportion of blended fuels in comparison to E10. During EGR operation, the introduction of butanol changed the combustion behavior, including prolonged ignition delay, shortened rapid burning duration, a reduced knock number, and knock intensity. The brake-specific fuel consumption (BSFC) increased with butanol addition, and when EGR was introduced, it decreased similarly to E10. The butanol−E10 blends exhibited lower exhaust gas temperature in comparison to E10 at various EGR rates. Hydrocarbon emissions from the blends increased slightly with the increased EGR rate, whereas CO emissions decreased. EGR exhibited high inhibition of NO x emissions for both blended fuels and E10, which were reduced by more than 80%. The NO x emissions from the blended fuels were 20−30% less than that of E10 with or without EGR conditions. Finally, EGR contributed to a reduction in BSFC and improvement in BTE for the butanol−E10 engine. The butanol−E10 blends exhibited a similar power performance, slightly reduced combustion stability, and acceptable emissions with respect to the baseline conditions.

“…The use of isobutanol and 1-butanol in neat form, as well as in 30 and 60 vol.% blends with gasoline, was investigated by Pechout et al [88] on a small PFI spark ignition engine with fully adjustable fuel injection and spark timing. Their goal was to evaluate the influence of the spark timing and fuel injection strategy on the combustion behavior with the different butanol fuels.…”

Isobutanol, one of the four isomers of butanol (C4H9OH), possesses some favorable properties that make it an attractive fuel for internal combustion engines. For instance, when compared to ethanol, isobutanol features a higher heating value and lower hygroscopicity (which prevents corrosion and enables it to be transported via pipelines). Moreover, its addition to gasoline does not distort the fuel blend’s vapor pressure to the same extent as ethanol does. All of this while having a high octane rating. Those advantages over ethanol suggest that isobutanol has the potential to be used as a gasoline oxygenate or even as a neat fuel. Furthermore, the advances made in biotechnology have enabled isobutanol to be produced from biomass more efficiently, allowing it to be used in compliance with existing renewable energy mandates. This article reviews some of the relevant literature dedicated to isobutanol as a motor fuel, covering its merits and drawbacks. Several studies on its combustion characteristics are also discussed. Most of the included literature refers to the use of isobutanol in spark-ignition (SI) engines, as its properties naturally lend themselves to such applications. However, isobutanol’s utilization in diesel engines is also addressed, along with a couple of low-temperature combustion examples.
