The current study investigates the performance and emission characteristics of a four stroke single cylinder diesel engine with 3 hole and 5 hole nozzle holes and with varying compression ratio with waste cooking oil (WCO) biodiesel blends. The WCO samples were collected from the restaurants in and around ballari and converted to biodiesel fuel with a two-step transesterification reaction. The fuel property tests showed that the properties of the WCO biodiesel were within the biodiesel standards. Diesel and diesel-WCO biodiesel blend (B10, B20 & B30) was used as fuel in a IC engine. The performance and emission characteristics of the engine were measured under varying load conditions. The experimental results showed that break thermal efficiency of 5 hole 18 cr(compression Ratio) B10 is maximum, SFC is minimum for 3 hole 18 cr Diesel, CO was found minimum for 5 hole 18cr B30, HC is found to be reduced for 3 hole 18 cr B20 and NOx is found to be reduced for 3 hole 17cr Diesel.
