The present study aimed to investigate the performance and exhaust emission characteristics of the diesel engine when fueled with a diesel mixed with different percentages of distilled Yang oleoresin. The purpose was to search for the optimal oil proportion to be eco-friendly and minimize the carbon footprint. Varied percentage concentrations of distilled Yang oleoresin were mixed with the diesel: 20% (B20), 40% (B40), 60% (B60), 80% (B80) and 100% (B100). A single-cylinder diesel engine was used to test the performance of the diesel, and blended diesel treatments, at speeds of 2,400 rpm, 2,000 rpm, 1,600 rpm, 1,200 rpm, and 800 rpm. The results showed that all blended fuel proportions gave maximum torque at a rotational speed of 1,600 rpm. The performance between B40 and diesel was not statistically significantly different (p > .05), however, B40 had a higher average torque and CO 2 emissions than pure diesel. In addition, the smoke of B40 was greater compared with diesel (~9.09%). The NOx emissions across all mixed fuel proportions were observed to be higher compared with diesel. In conclusion, B40 mixed fuel could provide an economically viable alternative to diesel because of its similar performance, emissions, and smoke.
