Özet:

Ethanol is an environmental friendly alternative diesel fuel that has received significant attention both as a possible renewable alternative fuel and as an additive to existing petroleum-based fuels. Beyond simply representing an additional fuel supply, ethanol exhibits several advantages when compared to existing petroleum fuel. The objective of this work is to investigate experimentally the effects of using different blends of specified percentages of ethanol on the engine performance and emissions and to compare it with that of conventional diesel fuel. Tests will be done on the ‘‘Engine Test Laboratory’’ of the Turkish Tractor Factory (TTF) using a fourcylinder, turbocharged and naturally aspirated, DI diesel engines. Engine performance parameters such as engine speed, torque, power, fuel consumption will be measured. At the same time, the engine emissions including particulate matter, unburned hydrocarbons, carbon monoxide, and NOX will also be recorded.
