“…The results indicated that all n-butanol blends had lower CO and UHC emissions. Williams et al [41] evaluated the maximum achievable thermal efficiency of SI engine using gasoline and n-butanol-gasoline blend. Results indicated that thermal efficiency, combustion and emissions were not adversely affected as a result of adding n-butanol to gasoline.…”

“…Williams et al evaluated the maximum achievable thermal efficiency of SI engine using gasoline and n-butanol-gasoline blend. Results indicated thermal efficiency, combustion, and emissions were not adversely affected due to butanol additive [18]. Gu et al tested five blended ratios (B0, B10, B30, B40, and B100) and results showed the UHC and CO emissions of the blends are lower than those of gasoline.…”

Butanol is considered as the more promising alternative fuel candidate because of its favorable chemical and physical properties over ethanol and methanol. In this study, the performance and emissions of a port fuel injected spark ignition engine fueled with butanol‐gasoline blends (0–60 vol % butanol blended with gasoline referred as G100‐B60), including brake thermal efficiency (BTE), brake specific fuel consumption (BSFC) and carbon monoxide (CO), unburned hydrocarbon (UHC), nitrogen oxide (NOx), were investigated under various equivalence ratio. Among the butanol‐gasoline blends, B30 performs well in engine performance and emissions due to its CO (2.3%–8.7%), UHC (12.4%–27.5%), and NOx (2.8%–19.6%) emissions compared to those of gasoline. Butanol can be a good alternative fuel to gasoline for its potential to reduce pollutant emissions. It is well known that engine tests are hard, time consuming, and high cost. Therefore, support vector regression (SVR) was used to predict the performance and emissions of the engine, where equivalence ratio and blend ratio were used as the input parameters, and BTE, BSFC, CO, UHC, and NOx were used as the output parameters. It was observed that the correlation coefficients and mean relative error were in the range of 0.9940–0.9998 and 0.1901–10.2570%, respectively. The SVR predictions of BTE, BSFC, CO, UHC, and NOx yielded the root‐mean‐squared‐errors of 0.0511%, 4.6058 g/kW h, 0.9995% vol, 7.7503 ppm vol and 38.5861 ppm, respectively. It could be indicated that the SVR provided an accurate and simple approach to analyze performance and exhaust emissions of spark ignition engine. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13042, 2019

“…Niass et al [23] observed that the higher knock resistance allowing earlier more efficient ignition timing with lower BSFC and CO 2 emission in fuel blends. Williams et al [24] experimentally investigated pure gasoline and n-butanol-gasoline blends under engine condition of 2000 r/min. The results were unchanged in terms of thermal efficiency, combustion and emissions (except for a reduction in CO 2 emission) when engine was operated with blends and neat gasoline.…”
