In this study, the effects of neutralized waste cooking oil biodiesel-diesel mixture (B30) and diesel fuels on combustion, performance and emission characteristics were investigated and compared experimentally in a four stroke, single cylinder direct injection diesel engine at different engine loads. For this reason the test engine was operated with different engine loads including 3.75, 7.5, 11.25, 15 and 18.75 Nm at 2200 rpm engine speed. The variations of in-cylinder pressure, heat release rate, cyclic variations, combustion duration and CO, CO2, NOx and soot emissions were determined. The test results showed that in-cylinder pressure and heat release rate increased with B30 compared to diesel for all engine loads due to better oxidation reactions. CO and soot emissions reduced  by about 57.9 % and 25.5 % with biodiesel compared to diesel at 18.75 Nm. It was also found that higher indicated mean effective pressure (imep) was obtained with B30 according to neat diesel. Besides, shorter combustion duration was determined with B30. Combustion and performance characteristics can be improved with biodiesel compared to diesel. As a result, neutralized waste cooking oil biodiesel-diesel fuel mixture (B30) could be easily used without engine modifications in diesel engine.
