The Effects of Camelina Ethyl Ester on the Performance of Diesel Engine and Combustion Characteristics

Abstract

Energy is a primary factor which is necessary for the basic needs of human life. Striking progress has been made in internal combustion engines since they were invented in which petroleum gasoline and diesel are generally used as an energy source and they have an important position in industry and in our daily lives. However, searches for new energy sources have been started due to the fact that petroleum-based fuels will run out and they damage the environment. This study is intended to determine the effects of cameline ethyl ester, which is obtained from raw camelina oil by using ethanol, on engine performance mixing it with diesel fuel proportionately. Diesel, 80% diesel and 20% cameline ethyl ester volumetrically and 100% cameline ethyl ester fuels were used as fuel. In the experiments, a four-cylinder, 1900cc, turbocharger supplier diesel engine with Common - Rail fuel injection system was used. The experiments were repeated 3 times and the averages of the results were taken. When the results were investigated, it was seen that maximum torque value was measured in diesel fuel as 167,68 Nm at 2000 rpm, maximum power value was measured in diesel fuel as 40,88 kW at 3000 rpm and minimum specific fuel consumption was measured in diesel fuel as 219,52 g/kWh at 2500 rpm. Power and torque values of B20 and B100 fuels were a little lower than in diesel fuel and their specific fuel consumption was higher than the others.
