“…Smoke level was the highest with RapO, followed by CotO and SunO. Rao and Mohan [15] investigated the effect of supercharging on a DDE performance with CotO and found that changes in injection pressure did not affect performance, but supercharging, even if low, provided better performance with BSFC reduction. Nwafor [16] examined fuel inlet temperature effect on RapO and resulted that fuel heating was beneficial at low speed and part-load operation.…”

A comparative experimental investigation was conducted to evaluate the performance and exhaust emissions of an agricultural tractor engine when fueled with sunflower oil, rapeseed oil, and cottonseed oil and their blends with diesel fuel (20/80, 40/60 and 70/30 volumetrically). Tests were also carried out with diesel fuel to be used as a reference point. Engine power, torque, BSFC, thermal efficiency, NO x and CO 2 were recorded for each tested fuel. All vegetable oils resulted in normal operation without problems during the short-term experiments. The 20/80 blends showed unstable results, in comparison to higher oil content fuels. Power, Torque and BSFC were higher as oil content was increased in the fuel. Rapeseed oil fuels showed increased power, torque and thermal efficiency with simultaneous lower BSFC in comparison to the other two vegetable oils. Cottonseed oil fuels gave better engine performance than sunflower oil fuels. In all oil types, NO x emissions were augmented when fuel oil percentage was increased. Cottonseed oil fuels led to higher NO x emission increase compared to rapeseed oil fuels. CO 2 emissions showed a tendency to be increased as the oil content was evolved. The highest CO 2 emissions were given by cottonseed oil fuels, followed by rapeseed and sunflower oil.

“…Rakopoulos 22 carried out a study on an analysis of the operation of a multi-cylinder, turbocharged, indirect injection diesel engine from a second-law analysis by using single-zone thermodynamic model. Rao et al 23 investigated the effects of supercharging on the performance of a direct injection diesel engine with the use of untreated cotton seed oil. It was seen a reduction in brake specific fuel consumption of about 15% when the engine is run at the recommended injection and supercharging pressure compared to naturally aspirated engine.…”

“…Several studies conducted worldwide have shown that vegetable oil, without any modification, can give engine performances comparable with those of diesel fuels. In general, it has been reported by most researchers that crude vegetable oils can be used as diesel engine fuel (Huzayyin et al, 2004;Ramadhas et al, 2004;Rao and Mohan, 2003;Nagaraj and Prabhu, 2002;Babu and Devaradjane, 2002;He and Bao, 2005;Zaher and Taman, 1993;Knothe et al, 1992;Shay, 1993). The most important advantage of vegetable oils is that they are renewable energy sources compared to the limited resources of petroleum.…”

In this study, an alternative diesel fuel, of which chemical modification was made by transesterification with short chain methyl alcohols, was produced from cottonseed oil. The modified products were then evaluated according to their fuel chemical properties as compared to diesel fuel. The purpose of this study is to investigate the emission characteristics of the fuel blend of 75% cottonseed oil methyl ester with 25% diesel fuel in a single cylinder unmodified diesel engine. The effects of biofuel and diesel fuel blend on a direct injected, four strokes, and single cylinder diesel engine exhaust emissions were studied. The results showed on the emissions of the engine that there was about 36% reduction in CO, about 18% reduction in CO 2 , and about 15% reduction in NOx. These results show that B75 fuel has better emission characteristics than diesel fuel. The reduction exhaust emissions made B75 a suitable alternative fuel for diesel engines and could help in controlling air pollution.
