Improved SI engine efficiency using Acetone–Butanol–Ethanol (ABE)

摘要: Abstract Alcohols, especially n-butanol, have received a lot of attention as potential fuels and shown to be possible alternative pure gasoline. The main issue preventing butanol’s use in modern engines is its relatively high cost production. ABE, the intermediate product ABE fermentation process for producing bio-butanol, being studied an fuel because it not only preserves advantages oxygenated fuels, but also lowers recovery individual component during fermentation. With development advanced technology, volumetric percentage acetone, butanol ethanol bio-solvents can precisely controlled. In this respect, desirable estimate performance different blends determine best blend optimize production accordingly. paper, with ratio, (A:B:E 3:6:1, 6:3:1 5:14:1), were combusted naturally aspirated, port-fuel injected spark ignited engine. these was evaluated through measurements in-cylinder pressure, various exhaust emissions. addition, gasoline neat n-butanol tested baselines comparison fuels. tests conducted at engine speed 1200 RPM loads 3 5 bar brake mean effective pressure (BMEP) under equivalence ratios. On basis experimental data, combustion characteristics emission behavior been presented discussed. It found that terms thermal efficiency, ABE(6:3:1) might much better suited fuel, relative ABE(3:6:1) or n-butanol.
