The Effects of Butanol-Gasoline Blends on the Performance and Exhaust Emissions of a Four-Stroke Spark Ignition Engine

Adil Md Saleh

This study examined the possibility of chancing  an indispensable energy to replace the Iraqi- origin gasoline. Iraqi gasoline has high  situations of lead and sulfur  composites, so the adulterants emitted from it are  veritably dangerous to  mortal health and the  terrain. In the current study, butanol was added to gasoline with volume  fragments of 25 – 75 gasoline( G75B25) and 50 butanol to 50 gasoline( G50B50). The influence of these two alcohol  rates of blending on the performance and exhaust emigrations of machine were compared. This study aims to  give a clean and healthy energy as an  volition to gasoline of Iraq with low combustion emigration content.  The results revealed that mixing gasoline with butanol led to better machine performance and lower exhaust emigrations compared to the case of gasoline energy alone. When comparing gasoline with G75B25  mix, it shows a relative  drop in the specific boscage  consumption( bsfc) of about 2 while( bsfc) was increased by2.38 when G50B50 was used compared to gasoline. The CO emigrations were reduced by27.79 and39.11. Also, HC  situations were reduced by15.93 and 28, independently, compared to gasoline. The studied  composites reduced noise  situations by1.64 and3.93. The  attained results confirm the possibility of  espousing any of the two studied  composites as a suitable  volition to gasoline and friendly to the Iraqi  terrain.
