This paper presents the results of investigations carried out on a three-cylinder, fourstroke, and direct-injection CI engine operated with terebinth (pistacia terebinthus) oil biodiesel. Terebinth oil was squized using the extraction method and therefore terebinth oil biodiesel was produced via the transesterification method. Terebinth oil biodiesel (B)-diesel fuel (D) blends were tested in a direct injection diesel engine at full load condition. Power values showed a trend of decreasing with all biodiesel fuels at high engine speeds. Specific fuel consumption (SFC) values increased depending on the amount of biodiesel in the test fuels. In general, exhaust emission profile of biodiesel fuels improved. CO and CO2 emissions decreased up to 34.54% and 10.69% respectively. However, NOx emissions increased up to 32.97%.
