Abstract

This study aimed to examine the effects of transesterification reaction temperature on the biodiesel properties and diesel engine performance. Biodiesel properties evaluated in this work included viscosity, density, and methyl ester content. Meanwhile, the diesel engine performance testing comprised the examination of the engines torque and power. The research was conducted in several stages, viz. producing biodiesel from fresh cooking oil with variations in transesterification temperature of 45, 55, and 65; testing the characteristics of biodiesel produced; blending biodiesel with petroleum diesel to result in B30 biodiesel fuel; and testing biodiesel fuel (B30) in diesel-engined vehicles. It was revealed that the higher transesterification temperature led to the lower biodiesel viscosity, the decreasing value of biodiesel density values, and the higher methyl ester content. Furthermore, it was also demonstrated that increase of the transesterification temperature resulted in the higher value of torque and power generated. However, compared to the petroleum diesel fuel (B0), biodiesel fuel (B30) exhibited the lower values of the engines torque and power. The highest average values of torque and power of B30 fueled diesel-engine were 108.11 Nm and 43.51 kW, respectively, provided by the biodiesel produced at the transesterification reaction temperature of 65.of 65.

Abstract

The purpose of this study was, 1) to examine the effect of the mixture composition between ceramics, TiO2, and activated carbon on catalytic converters on vehicle exhaust emissions, 2) test the composition of the mixture between ceramic, TiO2, and activated carbon in catalytic converters that produce the most exhaust emissions low. This study uses an experimental method with descriptive statistics. The independent variable is catalytic converter with a variety of ceramic material composition with a mixture of TiO2 and activated carbon. Control variables are the composition of the mixture, catalytic converter porosity control, standard exhaust without catalytic converter, engine speed used at stationary speed, and duration of testing time. Dependent variables are vehicle exhaust emissions CO and HC. The results of this study are, 1) The use of ceramic materials mixed with TiO2 and activated carbon in catalytic converters can reduce CO and HC content in gasoline-powered vehicles. 2) The best reduction is in the composition of 50% ceramic material, 25% TiO2, and 25% activated carbon, which is able to reduce CO content from 4.19% to 1.44% and HC gas. Suggestions from this study are, gasoline-powered vehicles can use catalytic converters made from Ceramic with a mixture of TiO2, and activated carbon with a composition of 50% ceramic material, 25% TiO2, and 25% activated carbon.
