Abstract

The growth of diesel vehicles has consequences for the consumption of diesel oil. Therefore, using Jatropha as an alternative fuel reduces dependence on diesel oil and it does not interfere with food availability. However, the high viscosity of jatropha oil makes the fuel pump work harder. In addition, the low calorific value reduces the quality of the fuel which creates unique problems. Ethanol, with its low viscosity and high oxygen content, is expected to be effective in reducing jatropha problems for diesel engines. Therefore, this study aims to evaluate the addition of ethanol to the brake torque, brake-specific fuel consumption, exhaust gas temperature, and smoke opacity. The 4JB1 diesel engine with an EGR was tested on a 10% (DJ10) and 20% (DJ20) diesel-jatropha mixture. The experimental results showed that brake torque increased by 1.51% in the DJ10 application, brake specific fuel consumption decreased by 7.05%, exhaust gas temperature decreased by 0.67%, and smoke opacity increased by 25.91%. While in the DJ20 application, brake torque increased by 3.19%, brake-specific fuel consumption decreased by 30.08%, exhaust gas temperature decreased by 0.67%, and smoke opacity increased by 69.03%.

Abstract

Alternative fuels are a primary solution to address fuel scarcity and the adverse effects of fossil fuels, such as air pollution. Bioethanol is notable for its simple production process and the use of flexible raw materials, although it is often derived from crops used in food production. Mangrove bioethanol, however, is produced from Rhizophora mucronata mangrove fruit, which is abundant, rich in carbohydrates, and not part of the human food chain. This study aimed to evaluate the use of mangrove bioethanol as a biofuel on engine performance and emission reduction in gasoline engines. Laboratory-based experiments were conducted using mangrove bioethanol blends at concentrations of 5% (GE5) and 10% (GE10). Pure gasoline (G100) served as the baseline for comparison. The results showed that GE10 delivered better engine performance and lower emissions than both G100 and GE5, likely due to its high octane rating and oxygen content. Performance improvements with GE10 included increases of 7.89% in brake torque (BT) and brake power (BP), 47.55% in brake thermal efficiency (BTE), and 20.33% in exhaust gas temperature (EGT), along with a 98% reduction in brake specific fuel consumption (BSFC). In terms of emissions, GE10 led to reductions in carbon monoxide (CO) and hydrocarbon (HC) emissions by 43.56% and 36.54%, respectively, while carbon dioxide (CO₂) emissions increased by 59.42%.
