Global concern over rising greenhouse gas emission levels and the availability of fossil fuels has led to the development of biofuels, and the use of gasoline formulations with oxygenated compounds has become common practice for improving fuel quality. This empirical study evaluated the effects of oxygenated gasoline fuel blends on air quality. Tests were conducted on a four-stroke, four-cylinder...
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...
In this study, we compared three different blended (20/80 by vol.) biodiesels of rice bran, neem, and cottonseed oils with varying degree of unsaturation. All three biodiesel blends decreased the brake thermal efficiency and increased the exhaust gas temperature of a single-cylinder diesel engine. They decreased CO, hydrocarbon, and smoke emissions, but increased NOx emissions. The biodiesels provided...
In this study, the effects of diisopropyl ether (DIPE)-gasoline (D10, D20, and D30) fuel blends on the performance, combustion, and emission characteristics of a spark ignition engine were investigated. In the study a four-stroke, four-cylinder multi-point fuel injection system (MPFI) engine with an eddy current dynamometer was used. The tests were performed at speeds between 1400rpm and 2800rpm under...
