“…5.7% more CO and 3.4% more HC. It was not surprising, because the engine compression ratio was only 8 : 1, and therefore RON 91 was sufficient [5]. An almost similar result was obtained as well, where the powers, torques and specific fuel consumptions from RON 91 fueled engine are astonishingly better than that from RON 95.…”

“…Sayin et al (2005) demonstrated that using RON 95 instead of RON 91 not only increased its BSFC by as much as 5.6%, but also gas emissions, i.e. 5.7% more CO and 3.4% more HC.…”

“…SI engines have been adapted for three-way catalysts with advanced engine designs and improved fuel properties. Lately, researchers [8][9][10][11] have been focusing more on the octane number. This is because the exhaust emissions from automobiles and the subsequent engine performance are known to be determined by the gasoline quality, which depends on the octane number.…”

The resistance of gasoline to knocking is critically determined by the octane number. The engine will encounter a significant waste of power, reduced efficiency and enhanced emission levels if a well-defined gasoline octane number is not employed. In this study, the engine performance and emission of hazardous gases were experimentally investigated through the use of three gasoline fuels (RON95, 97 and 102). The engine selected for the testing was a 1.6-L four-cylinder Toyota 4A-GE Blacktop VVT with the original ECU. The engine was run at different constants for various part load conditions as well as at constant throttle body. The engine that was operated with RON97 fuel was found to display positive improvements in terms of the brake specific fuel consumption of the engine, reduced at an average of 5 and 10%, compared to RON102 and RON95 fuels, respectively. Furthermore, the engine operated with RON102 fuel exhibited higher torque and engine power compared to RON97 and RON95. The brake thermal efficiency for both RON97 and RON102 fuels was remarkably improved at an average of 12% compared to RON95. The incorporation of RON102 fuel reduced the emission of NOX compared to RON95 and RON97 fuels at an average of 34% and 40%, respectively. The RON102 fuel produced the highest HC emission compared to RON97 and RON95. The CO emission was found to be higher for RON102 fuel compared to RON97 and RON95 at an average of 12.4% and 17%, respectively. The study concluded that although engine performance and efficiency versus gasoline depend highly on the engine design parameters, RON97 is able to deliver high performance and efficiency in all conditions. Therefore, it is recommended that RON97 be used instead of RON95 to achieve better performance with this type of engine.

Motor Gasoline (MOGAS) that serves as modifiers thermal energy into mechanical energy with a Research Octane Number (RON) of 91 was produced by mixing (blending) of two components. RON are high is one of MOGAS specifications needed for good engine performance. To obtain a MOGAS with high RON usually needs additional materials, chemical components. In this work, we don't need any additional materials to increase the RON. In the field of oil and gas blending method is a method that is widely used to acquire new products that are superior and achieve quality standards. The components used in blending these are products with a value of RON 88 and 92. Examination of specific gravity (ASTM D1298) was conducted to obtain specific gravity (SG) and temperature observations (T), while the ASTM D86 distillation examination was conducted to determine the components in materials. The results showed that the product specifications in accordance with the existing products on the market. The acquisition of distillate reached 95% with losses of about 3.9%, and the residue of 1.1%.
