Abstract
Fossil fuels are commonly used fuel for automobiles. The exhaust gas emission of fossil fuel causes a serious problem. This arises the need for alternative fuels. Biodiesel is a renewable fuel produced from plant and animal material by trancesterification process. Transesterification is base catalyzed reaction, they convert triglycerides into mono alkyl esters. The main problem of biodiesel is its high cost which could be reduced by use of less expensive feed stock. Dates seed oil is obtained from the extraction of dates seed. Dates seed oil is used for production of biodiesel. Since, the dates oil is extracted from the dates seed, which is a waste, the usage of dates seed for the production of dates seed biodiesel becomes very inexpensive and feasible. The calorific value of dates seed biodiesel is 38000 KJ/kg while the density is 879 kg/m³, flash point is 122 °C, viscosity is 5.2 mm²/s and cetane number is 42. A single cylinder, 4 stroke, water cooled diesel engine of Kirloskar Oil Engine TAF 1 is used for evaluating combustion and Emission characteristics of dates seed biodiesel blends and diesel. The cylinder pressure for all the dates seed biodiesel blends is lower than the diesel and the Emissions parameters HC, NOx, CO, Smoke are lower than the diesel where the exhaust temperature, CO2 are higher than diesel, it indicates the complete combustion of biodiesel blends.
