A limited number of studies have been previously undertaken to evaluate the suitability of iso-butanol as an alternative fuel for spark ignition engines (Andziulis 2006;Alasfour 1997;Popuri and Bata 1993;Rice et al 1991;Bata et al 1989a and1989b). Most of these studies have shown that alcohol fuels can have a level of performance comparable to that of diesel and gasoline fuels.…”

abstract. The effect of iso-butanol addition to diesel fuel on engine performance parameters has been experimentally investigated. The used engine was a single cylinder four stroke CI engine Type Lister 1-8. The tests were performed at engine speed that ranges from 375 to 625 with an increment of 42 rpm at different loads and with 10, 20, 30 and 40% v/v iso-butanol-diesel fuel blends. The overall engine performance parameters measured included air-fuel ratio (AFR), exhaust gas temperature, brake power (B p ), brake specific fuel consumption (bsfc) and brake thermal efficiency (η th ). The experimental results show that AFR, exhaust gas temperature, (B p ) and (η bth ) decreased and bsfc increased with iso-butanol addition compared to net diesel fuel. Also, the obtained results indicate that the engine performance parameters when using up to 30% iso-butanol in fuel blends are better than that of 40%.

“…Tertbutanol, at low volumetric fractions, can be used to improve the knock behaviour of gasoline, but is not considered to be used as an alternative fuel at higher volumetric concentrations, due to its high melting point. Iso-butanol can increase the octane number of the gasoline in blends [7], it can also get lower brake specific fuel consumption and increase the power and thermal efficiency compared to methanol and ethanol blends [8].…”

The formation of polycyclic aromatic hydrocarbons (PAHs) and soot from the pyrolysis of the four butanol isomers: 1-butanol, 2-butanol, iso-butanol and tert-butanol, at three reaction temperatures (1275, 1375 and 1475 K) has been studied. The identification and quantification of the sixteen PAHs, classified by the Environmental Protection Agency (EPA) as priority pollutants, were done using the gas chromatography-mass spectrometry (GC-MS) technique. The soot formed was collected at the reactor outlet. Light gases formed were also quantified. The harmful potential of the PAHs through the benzo[a]pyrene equivalent, B[a]P-eq amount, has been evaluated. The main results show that the highest formation of light gases was obtained from the pyrolysis of isobutanol at 1275 K. The formation of H2 increases significantly as the temperature increases, following the Hydrogen abstraction carbon addition (HACA) route that leads to form PAHs which subsequently form soot. The tendency to soot formation, under the experimental conditions of the present study, is ranked as follows: tert-butanol, 2butanol, 1-butanol and iso-butanol. The highest PAHs amount and the highest toxic potential, expressed as B[a]P-eq amount, were found in the pyrolysis of all butanol isomers at 1275 K.

“…Saab's goal was a more powerful engine. Popuri and Bata 49 used the same concept to make a more fuel-efficient engine. They found that the brake-specific fuel consumption of isobutanol blends could be as good as, or better than, that of gasoline if the compression ratio of their single-cylinder research engine was adjusted to account for the higher anti-knock qualities of the alcohol additives.…”
