Abstract: This study was conducted to investigate the effect of diesel fuels on in-cylinder pressure, engine performance and exhaust emissions. In this study, common-rail diesel engine was used with a cylinder volume of 1,500 cc. The engine was operated at 1,750 rpm and 40-100 Nm fixed engine loads. Besides, diesel fuel without any addition and L5Cu-added diesel fuel with four variables at 60 Nm of engine torque was examined by multivariate regression analysis, and pressure equations were produced. As a result, the engine at loads of 40 Nm and 60 Nm, which was also fed with L5Cu additive, was found to have reduced the specific fuel consumption and thermal efficiency by 1.9% and 0.73% respectively; however, at 80 Nm and 100 Nm loads, it was found to have increased by 0.3% and 0.7% respectively. It was concluded that the L5Cu additive at all engine loads caused a severe reduction in HC emission. [Received: March 30, 2020; Accepted: April 26, 2020]
