Abstract This study is aimed at reducing NOx, Smoke, HC, CO emissions from single-cylinder, four-stroke, and water cooled diesel engine. The research engine is fueled with diesel and two blends of butanol and diesel at atmospheric conditions. Neat diesel is termed as D100, 10%, and 20% Volume of butanol dispersed in D100 is termed as D90B10 and D80B20 respectively. The chemical and physical properties of D100, D90B10 and D80B20 fall within the limits of ASTM standards. Results revealed that enhanced chemical properties and higher latent heat of vaporization of butanol lowered the CO, HC, smoke, and NOX emissions of diesel fueled research diesel engine.

研究柴油机中柴油和丁醇混合物的排放分析

摘要 本研究旨在减少单缸、四冲程和水冷柴油机的 NOx、Smoke、HC、CO 排放。研究发动机在大气条件下以柴油和丁醇和柴油的两种混合物为燃料。纯柴油称为 D100、10% 和 20%。分散在 D100 中的丁醇体积分别称为 D90B10 和 D80B20。D100、D90B10 和 D80B20 的化学和物理特性均在 ASTM 标准的范围内。结果表明，增强的丁醇化学性质和更高的汽化潜热降低了以柴油为燃料的研究柴油发动机的 CO、HC、烟雾和 NOX 排放。
