A significant increase in every nation’s energy demand and insufficient conventional energy reservoirs for long duration, there became necessary requirement to shift from non-renewable to renewable energy sources. Diesel and biodiesel fuels have different thermo physical properties; hence performance and emission output parameters are also different compares with each other. For effective utilization of biodiesel, the characteristics of conventional single cylinder diesel engine with changing load and static speed (1500 rev/min) conditions are evaluated. The baseline diesel, biodiesel - diesel (BD) B08 [8% biodiesel blended with diesel] and ethanol-biodiesel-diesel (EBD) E05B08 [5% ethanol and 8% biodiesel blended with diesel] by v/v ratio are used for experimentation. Brake thermal efficiency (BTE) reduced from 29.14% with diesel to 27.64% with biodiesel and 28.49% with ethanol blends. It is observed that BTE reduced by 1.5% with biodiesel blend and 0.65% only with ethanol blend. The CO, HC and opacity of exhaust gas pollutants are reduced with biodiesel blend fuel and also further reduced with EBD blend. NOx formation with B08 fuel is enhanced to 1967 ppm from 1557 ppm of baseline diesel whereas it is slightly increased to 1734 ppm by E05B08 fuel.

In this investigation, tests were conducted on a single cylinder DI diesel engine fueled with neat diesel and biodiesel as baseline fuel with addition of 5 to 20% DEE on a volume basis in steps of 5 vol.% as supplementary oxygenated fuel to analyze the simultaneous reduction of smoke and oxides of nitrogen. Some physicochemical properties of test fuels such as heating value, viscosity, specific gravity and distillation profile were also determined in accordance to the ASTM standards. The results obtained from the engine tests have shown a significant reduction in NOX emissions especially for biodiesel and a little decrease in smoke of DEE blends compared with baseline fuels. A global overview of the results has shown that the 5% DEE-Diesel fuel and 15% DEE-Biodiesel blend are the optimal blend based on performance and emission characteristics.

The world needs an alternative fuels that could maintain the world running on its wheels due to the increasing energy demand and uncertainty in availability of the fossil fuels. The present investigation analyzes the scope of utilizing the Deccan hemp oil based biodiesel derived from jute seed as an alternative to the diesel. Experimental investigation was carried out at diesel engine with different loads from 0% to 100% and 10% overload condition under a constant speed of 1500 rpm. It was found that the reduction in brake thermal efficiency and higher brake specific fuel consumption was observed with biodiesel in comparison with diesel. The carbon monoxide (CO), carbon-dioxide (CO2), unburnt hydrocarbon (HC) and nitric oxide (NO) emissions for Deccan hemp oil based biodiesel were reduced by 0.2% vol, 1.6% vol, 62.5%, 36.84% whereas slightly higher smoke emission was observed when compared to diesel fuel. These studies revealed that Deccan hemp oil based biodiesel can be used as a fuel in compression ignition engine without any engine modifications.

The paper presents an experimental investigation, to evaluate the performance and emission characteristics of a direct injection diesel engine using diesel-ethanol blends with aqueous cerium oxide nano fluid (ACN) as additive at different load conditions. The test fuel (D85E15ACN) prepared using ultrasonic sonicator, contains diesel 85%, ethanol 15% (D85+E15) by volume, with 1ml of aqueous cerium oxide nanofluid (ACN) added with the blend. The results show that, when the engine is run with D85E15ACN, there is an increase in brake thermal efficiency and reduction in hydrocarbon (HC), carbon monoxide (CO) and smoke emissions, compared to that of neat diesel.However, nitric oxide (NO) emission are more for D85E15ACN.
