Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This paper intended to indicate the experimental investigation for presenting the influence of employing many fuel additives on spark ignition (SI) engine performance. Three types of fuel additives comprising, Octane booster, Gasoline booster, and Gasoline additive, are added separately with pure Gasoline for a volumetric addition of 2.5, 5, 10 mL/L, 1.5, 3, 6 mL/L, and 2.5, 5, 10 mL/L respectively, whenever 5, 3, 5 mL/L are the normal volumetric addition respectively. An SI internal combustion engine is used with rotational speed range of 1500 - 2500 rpm, wherever the nine blends and the pure Gasoline itself are employed. The results showed improvements in engine performance when using Octane booster. The brake power rises by 8.3%, 14% and 19.4% respectively at the use of half, double, and normal addition of Octane booster compared to that of using pure fuel of Gasoline. Brake thermal efficiency increases to its maximum value by 18.4% when using normal addition, and to its minimum magnitude for using half addition of 7.3% of Octane booster. It exhibited that the magnitude variations in brake specific fuel consumption through using half, double, and normal addition for using Octane booster was 9%, 14.7% and 20.2% respectively compared to employing pure Gasoline only. The results of using Gasoline booster and Gasoline additives found effect on SI internal combustion engine have similar influence as of using Octane Booster. It is noticed that using of additive type Octane booster and using a normal amount of additives lead to reduction in CO concentration in emissions compared with only pure Gasoline and other additives concentrations
In this study, a new structure of the positive output super lift Luo (POSL) converter is presented. The major aim of this new converter is to provide ultra voltage transfer ratio gain. The basic (POSL) convertr has voltage lift circuit (cell), which contains single inductor, diode and capacitor. The disadvantage of the basic (POSL) converter is that it becomes the same with boost converter in case of increasing the output voltage at high duty cycle. The new converter provides ultra voltage transfer ratio gain by adding the switched capacitor inductor cell, which consists of two inductors, two diodes and one capacitor to the basic (POSL) converter and matching it with suitable connection. This allows gaining practically more than triple rise in the line to output voltage ratio. Pulse width modulation (PWM) voltage mode controller strategy is used to control the new converter. The new converter works by using two switches and they work instantaneously to make the control simple, more efficient and more effective. In addition, the equations of voltage and current in continuous and discontinuous conduction modes (CCM) and (DCM) are analyzed at steady state error. The simulation and practical results shows the effectiveness of matching the new converter to the theoretical analysis. The new converter has high efficiency that reaches 96.1% in comparison with the basic (POSL) converter, which has 94.1%. The simulation has done by using Matlab/Simulink program
