Investigation on Effect of Oxygenated Additive on Multicylinder Diesel Engine Performance and Emission
This paper present the experimental investigation on effect of oxygenated additives on multi-cylinder Diesel engine performance and emission. The experimental trail was carried out at constant speed of 1500rpm with variable load conditions and 10% of oxygenated additive in diesel fuel. Six different additives were selected for investigation. After the experimentation, it’s found that DIGILYME shows least brake specific fuel consumption of all other additives but around 10 -20% higher than that of diesel for the same load variation. All additive shows rise in EGT except DMC which is quite close to that of diesel. Brake thermal efficiency of DMC is high at idle to moderate load after that it drop than that of diesel due to low calorific value. It shows around15% rise in low load condition. DMC looks very promising in emission control. DMC shows around 15-30 drop in CO high load condition while 20 % drop in HC. Also It is good option in NOx control as it shows around 10% drop at low load and 15% drop at higher load condition. The only limitation is high smoke production by DMC where other additive like N Butyl Alcohol help in lowering smoke production that is its show around 30% drop at high load condition.
