Abstract

Today, because of expansion in oil costs, restricted petroleum product assets, ecological thought and an unnatural weather change, the ethanol fills have been centered around elective powers. The use of ethanol is more effective in compression ignition (CI) engines because it is about 30 percent more effective than in spark-ignition (SI) engines due to increased combustion efficiency. The use of ethanol in low heat rejection (LHR) engines helps raise the temperature of the combustion chamber, creating a heat barrier around it. The effect of coating the cylinder head, pistons, and valves of a diesel engine with the molybdenum (Mo) and Al2O3+TiO2 is investigated in this work. As a result, the coated pieces of the combustion chamber were accommodated by a heated boundary. The coated and uncoated engines were evaluated under similar engine operating conditions. The CO, HC, and smoke emissions were reduced, but NOx emissions slightly increased for the Al2O3+TiO2 coated engine. As a result, it has the most beneficial environmental effects.
