The high energy demand in the industrialized world as well as the pollution problems caused due to the use of fossil fuels make it increasingly necessary to develop a new renewable energy source. This work transesterified waste cooking oil with methanol and investigated combustion characteristics of the resulting methyl ester and its blends in a compression ignition engine. The methyl ester and its blends were combusted in a direct injection single cylinder four-stroke air cooled diesel engine one after the other and the combustion characteristics such as combustion temperature, cylinder pressure, heat release rate and ignition delay were investigated at different loads of 0.0, 20.0, 40.0, 60.0, 80.0 and 100.0% with full throttle speed of the engine. Results obtained showed that the combustion temperature, cylinder pressure and heat release rate increased as the load increased for each blend. And for each load, the combustion temperature, cylinder pressure and heat release rate increased as the percentage of methyl ester in the blends increased. While ignition delay reduced as the load increased but increased as the percentage of methyl ester in the blends increased. The study concludes that waste cooking oil methyl ester and its blends compare favorably with petroleum diesel and possessed combustion characteristics very close to that of fossil diesel in terms of combustion temperature, cylinder pressure, heat release rate and ignition delay when combusted in a compression ignition engine.

Abstract
The high energy demand in the industrialized world as well as the pollution problems caused due to the use of fossil fuels make it increasingly necessary to develop a new renewable energy source. This work transesterified waste cooking oil with methanol and investigated combustion characteristics of the resulting methyl ester and its blends in a compression ignition engine. The methyl ester and its blends were combusted in a direct injection single cylinder four-stroke air cooled diesel engine one after the other and the combustion characteristics such as combustion temperature, cylinder pressure, heat release rate and ignition delay were investigated at different loads of 0.0, 20.0, 40.0, 60.0, 80.0 and 100.0% with full throttle speed of the engine. Results obtained showed that the combustion temperature, cylinder pressure and heat release rate increased as the load increased for each blend. And for each load, the combustion temperature, cylinder pressure and heat release rate increased as the percentage of methyl ester in the blends increased. While ignition delay reduced as the load increased but increased as the percentage of methyl ester in the blends increased. The study concludes that waste cooking oil methyl ester and its blends compare favorably with petroleum diesel and possessed combustion characteristics very close to that of fossil diesel in terms of combustion temperature, cylinder pressure, heat release rate and ignition delay when combusted in a compression ignition engine.
