Used Vegetable Oil

An experimental study to measure the evaporation rates, engine performance and emission characteristics of used vegetable oil methyl ester and its blends with producer gas on naturally aspirated vertical single cylinder water cooled four stroke single cylinder diesel engine is presented. The thermo-physical properties of all the bio fuel blends have been measured and presented. Evaporation rates of used vegetable oil methyl ester and its blends have been measured under slow convective environment of air flowing with a constant temperature and the values are compared with fossil diesel. Evaporation constants have been determined by using the droplet regression rate data. The fossil diesel, biodiesel blends and producer gas have been utilized in the test engine with different load conditions to evaluate the performance and emission characteristics of diesel engine and the results are compared with each other. From these observations, it could be noted that, smoke and hydrocarbon drastically reduced with biodiesel in the standard diesel engine without any modifications.

Oil Sunflower

In the present work, the combustion, performance and emission characteristics of sunflower oil, sunflower methyl ester and its blends were studied and compared with diesel by employing them as fuel in a single cylinder, direct injection, 4.4 KW, air cooled diesel engine. Emission measurements were carried out using five-gas exhaust gas analyzer and smoke meter. The performance characteristics of Sunflower oil, Sunflower methyl ester and its blends were comparable with those of diesel. The components of exhaust such as HC, CO, NOx and soot concentration of the fuels were measured and presented as a function of load and it was observed that the blends had similar performance and emission characteristics as those of diesel. NOx emissions of sunflower oil methyl ester were slightly higher than that of diesel but that of sunflower oil was slightly lower than that of diesel. With respect to the combustion characteristics it was found that the biofuels have lower ignition delay than diesel. The heat release rate was very high for diesel than for the biofuel.
