The main objective of this paper is to investigate spray and flame characteristics of waste cooking oil (WCO) biodiesel and diesel fuel in a single-cylinder common-rail direct injection optical diesel engine. The tests were conducted at 800 r/min with injection pressure of 80 MPa and injection timing of -5 crank angle degree (CAD) after top dead center (aTDC). The results indicated that start of injection was later with WCO biodiesel than that of diesel. Spray tip penetration length of WCO biodiesel was longer and spray angle was narrower than those of diesel due to poor atomization characteristics. In terms of combustion, WCO biodiesel showed later start of combustion even though it had higher cetane number. The natural flame luminosity of WCO biodiesel combustion was lower than diesel due to its lower particulate matter emissions level.
