The objective of this study was to determine the performance and emission of diesel engine using Yang (Dipterocarpus alatus) oil compared with conventional diesel fuel. This test was conducted on a single-cylinder diesel engine at 800, 1200, 1600, 2000, and 2400 rpm, then measured and recorded the values. The experimental results showed that torque, brake power and brake thermal efficiency of the engine using Yang oil showed average increased by 5.22%, 5.38% and 4.27%, respectively and brake specific fuel consumption of the engine using Yang oil showed an average decreased by 6.27% compared with those from diesel. The exhaust gas emission of engine using Yang oil were higher than diesel; CO, CO₂ and NO_x emissions increased slightly by 0.3% Vol., 2.02% Vol. and 18.80 ppm, respectively.

杨（Dipterocarpus alatus）燃油供油的单缸柴油机的性能和排放特性

这项研究的目的是确定与传统柴油相比，使用杨（Dipterocarpus alatus）油的柴油发动机的性能和排放。该测试是在800、1200、1600、2000和2400 rpm的单缸柴油发动机上进行的，然后测量并记录这些值。实验结果表明，使用杨油的发动机的扭矩，制动功率和制动热效率分别平均提高了5.22％，5.38％和4.27％，使用杨油的发动机的制动比油耗平均降低了6.27。 ％与柴油相比。使用扬油的发动机废气排放量高于柴油。CO，CO ₂和NO _x排放量微增0.3％体积，2.02％体积 和18.80 ppm。
