摘要

柴油车的增长对柴油的消费产生了影响。因此，使用麻疯树作为替代燃料减少了对柴油的依赖，而且不会影响食物的供应。然而，麻疯树油的高粘度使燃油泵的工作更加困难。此外，低热值降低了燃料的质量，从而产生了独特的问题。乙醇具有低粘度和高氧含量，有望有效地减少柴油发动机的麻疯树问题。因此，本研究旨在评估乙醇的加入对制动扭矩、制动特定油耗、废气温度和烟雾不透明度的影响。带有EGR的4JB1柴油机在10% (DJ10)和20% (DJ20)柴油-麻疯树混合物上进行了测试。实验结果表明，DJ10应用后，制动扭矩提高1.51%，制动比油耗降低7.05%，废气温度降低0.67%，烟浊度提高25.91%。而在DJ20应用中，制动扭矩提高了3.19%，制动油耗降低了30.08%，废气温度降低了0.67%，烟雾不透明度提高了69.03%。

The Effect of Ethanol on Brake Torque, Brake Specific Fuel Consumption, Smoke Opacity, and Exhaust Gas Temperature of Diesel Engine 4JB1 Fueled by Diesel-Jatropha Oil

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%.
