Effects of ethanol addition on performance and emissions of a turbocharged indirect injection Diesel engine running at different injection pressures

摘要: Abstract Ethanol is an alternative renewable fuel produced from different agricultural products. The ethanol–Diesel emulsion technique one of the techniques to use ethanol in Diesel engines. most important advantage this be able without any modification In study, effects addition (10% and 15% volume) No. 2 on performance emissions a four stroke cycle, cylinder turbocharged indirect injection engine having pressures (150, 200 250 bar) at full load were investigated. 1% isopropanol was added mixtures satisfy homogeneity prevent phase separation. Experimental results showed that reduces CO, soot SO2 emissions, although it caused increase NOx emission approximately 12.5% (for 10% addition) 20% power reductions. It also found increasing pressure running with decreased CO smoke especially between 1500 2500 rpm, respect fuel, while some reduction power.
