“…The values of NOx are in good agreement with previous accounts of reduced adiabatic flame temperatures with such alcohol fuels (32)(33)(34). However, high values of engine-out CO were observed with butanol, which perhaps indicates a more complicated interaction than just differences in peak gas temperatures.…”

“…Finally a commercial grade E85 was also acquired and an equivalent two-component splash blend of 85% volume ethanol/15% volume iso-octane prepared to help compare the effects of higher ethanol content fuels. While "lower" alcohols of reduced carbon count such as methanol and ethanol have previously warranted significant interest, "higher" alcohols such as propanol, butanol and pentanol have also previously been considered for automotive use (32)(33)(34). From a thermodynamic stance the higher alcohols generally exhibit higher calorific value (and hence better volumetric fuel consumption), better water tolerance, volatility control and lower Reid vapour pressure.…”

This work involved study of the effects of alcohol blends on combustion, fuel economy and emissions in a single cylinder research engine equipped with a mechanical fully variable valvetrain on the inlet and variable valve timing on the exhaust. A number of splash blends of gasoline, iso-octane, ethanol and butanol were examined during port fuel injected early inlet valve closing operation, both with and without variable valve timing. Under low valve overlap conditions, it was apparent that the inlet valve durations/lifts required for full unthrottled operation were remarkably similar for the wide range of blends studied. However, with high valve overlap differences in burning velocities and internal EGR tolerances warranted changes in these valve settings. In turn, it was concluded that high ethanol content blends facilitated minimum throttling at the inlet valve itself and the largest relative savings in terms of fuel consumption, engine-out emissions of NOx and (corrected) unburned hydrocarbons.

“…New sources of energy such as alcohols can be produced from a number of non-fossil raw materials, and they may offer strategic and economic benefits. Bata et al (1989a) investigated the effect of 20% butanol-gasoline blends on the exhaust gas temperature of a 4-cylinder engine; their work covered stoichiometric and rich fuel/air equivalence ratio. Research on the automobile focus on studies of utilizing alcohol-gasoline blends as alternative fuels in order to solve problems inherent in spark ignition engines such as undesirable NO V formation and ozone formation, and to maintain high engine thermal efficiency.…”

The effect of methanol and butanol addition to gasoline on brake specific fuel consumption (b.s.f.c.), exhaust gas temperature, and thermal efficiency has been experimentally investigated. A Hydra single cylinder, spark ignition, fuel injection engine was used over a wide range of fuel/air equivalence ratio (ϕ=0⋅8 to 1⋅3) for 30% volume alcohol–gasoline blends. The goal of this work is to study the engine performance when methanol and butanol–gasoline blends are used. The performance measurements show that there is an increase in b.s.f.c. when using alcohol–gasoline blends, and b.s.f.c. of a butanol–gasoline blend is less than for a methanol–gasoline blend. The experimental results show that the engine thermal efficiency was decreased when fueled with alcohol–gasoline blends. It was found that there was about a 4.5% reduction in engine thermal efficiency at ϕ=1⋅0 when 30% butanol was blended with gasoline compared to pure gasoline. The exhaust gas temperature measurements show that there is an increase in temperature in the case of using gasoline as compared to alcohol–gasoline blends, and that the temperature reaches a maximum at ϕ≈1⋅1 when using gasoline and alcohol–gasoline blends. © 1997 by John Wiley & Sons, Ltd.

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.…”

The Effect of Iso‐butanol‐diesel Blends on Engine Performance

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%.
