Performance and Emission Characteristics of a Single-Cylinder Diesel Engine Fueled with Yang (Dipterocarpus alatus) Oil

Abstract

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.
