Abstract
The utilization of alternative fuels in internal combustion engines has received considerable attention in recent years due to the need for sustainable and environmentally friendly energy sources. This study focuses on the concept of dual-fuel combustion, specifically the combination of diesel fuel and ethanol, in a compression ignition engine. Ethanol, a renewable fuel source, also helps to reduce fossil fuel dependence and greenhouse gas emissions. In this study, the ethanol is injected into the intake manifold while the diesel fuel is injected directly into the combustion chamber. The engine used is a single-cylinder research engine that allows operation with two fuels. Diesel oil serves as the ignition fuel, which ignites the ethanol-air mixture. A constant IMEP value was specified for these tests. To meet this requirement, the mass of diesel injected into the pilot injection was kept constant, while it was gradually reduced in the main injection. As the diesel from the main injection decreased, ethanol was injected with an appropriate pulse to maintain the same IMEP value. The main objective of this study is to analyze the acceptable substitution rate of ethanol in a diesel engine and the emissions resulting from combustion. However, the implementation of diesel and ethanol dual-fuel engines requires careful calibration of injection timing and rates to ensure optimal performance and emissions.
