The present work examines the oxygen enrichment on diesel engine at the fuel side and air side. Oxygenation at the fuel side is done by blending the Dimethyl carbonate (DMC) additive with a maximum percentage of oxygen whereas that of air side is done by coupling a blower to the inlet manifold. The experiment was conducted with four different blends of oxygenated additives with diesel, and then the effects of supercharging in these blends were analyzed. The performance and emission characteristics of DMC blend with diesel fuel were examined and compared with the base engine characteristics. The results show that for 5% of DMC there is an increase in the thermal efficiency of the engine and decrease the CO emissions.

To meet the challenges of increased energy need and concerned about environmental friendly, renewable fuels are being explored in the current energy scenario. In the present study non edible Linseed oil was used as alternative source for diesel engine fuel. The physico-chemical properties were evaluated and compared with mineral Diesel and found in close resemblance. The fuel was tested by using performance and emission parameters on an unmodified single cylinder diesel engine. The study was done by using diesel & Diesel-linseed oil blends at various loads from no load to 100% loads with interval of 20%. The linseed fuel was blended into 5%, 10%, 15% and 20% v/v ratio with neat diesel and compared with baseline data of neat diesel operation. Performance parameters such as brake thermal efficiency and brake specific fuel consumptions were studied and emission parameters such as CO (carbon mono oxide), UBHC (unburned hydrocarbon), NOx (oxides of nitrogen), CO2 (carbon di oxide), exhaust temperature were measured. The thermal efficiency of the engine was lower and the brake specific energy consumption of the engine was higher when the engine was fueled with Linseed oil-Diesel blends compared to diesel fuel. Emission characteristics are better than diesel fuel. NOx formations, using various fuel blends during the whole range of experiment were lower than diesel fuel. The results from the experimental study suggest that the linseed oil could be a potential substitute for diesel engine in the near future as far as small and medium energy productions are concerned.

Experimental tests have been carried out to evaluate the performance and emissions characteristics of a diesel engine when fuelled by blends of 25% vegetable oil with 75% diesel fuel, 50% vegetable oil with 50% diesel fuel, 75% vegetable oil with 25% diesel fuel, and 100% vegetable oil, compared with the performance, emissions characteristics of 100% diesel fuel. The series of tests were conducted and repeated six times using each of the test fuels. 100% of ordinary diesel fuel was also used for comparison purposes. The engine worked at a fixed speed of 1500 r/min, but at different loads respectively, i.e. 0%, 25%, 50%, 75% and 100% of the engine load. The performance and the emission characteristics of exhaust gases of the engine were compared and analyzed. The experimental results showed that the carbon monoxide (CO) emission from the vegetable oil and vegetable oil/diesel fuel blends were nearly all higher than that from pure diesel fuel at the engine 0% load to 75% load. Only at the 100% engine load point, the CO emission of vegetable oil and vegetable oil/diesel fuel blends was lower than that of diesel fuel. The hydrocarbon (HC) emission of vegetable oil and vegetable/diesel fuel blends were lower than that of diesel fuel, except that 50% of vegetable oil and 50% diesel fuel blend was a little higher than that of diesel fuel. The oxides of nitrogen (NOx) emission of vegetable oil and vegetable oil/diesel fuel blends, at the range of tests, were lower than that of diesel fuel.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.
