| Popis: | With growing concerns about environmental pollution caused by automobiles, biofuels containing oxygen – also known as oxygenates – are being researched very rigorously. In this article, we have inspected the use of isopropanol/gasoline blends, as fuel in a 4 – cylinder Spark Ignition engine with Multi-Point Fuel Injection System. Isopropanol was mixed with Unleaded Gasoline in proportions of 10, 20 and 30% by volume (IPA10, IPA20 and IPA30). It is found that with the use of isopropanol/gasoline blends in Spark Ignition Engine, Brake Thermal Efficiency and NOx emissions increased whereas carbon monoxide and hydrocarbon emissions decreased. When the spark timing was retarded by 2 degrees, it was found that isopropanol/gasoline blends emitted lower NOx emissions than those at original spark timing. Isopropanol blends also increased the in-cylinder pressure values and heat release rate values. |
